一种烟草薄片的制备方法及其应用A kind of preparation method and application of tobacco sheet

技术领域technical field

本发明属于烟草薄片技术领域，具体涉及一种烟草薄片的制备方法及其应用。The invention belongs to the technical field of tobacco sheets, and in particular relates to a preparation method and application of tobacco sheets.

背景技术Background technique

卷烟工业再生烟草薄片是将卷烟加工过程中产生的废料、废弃的烟梗、烟叶和劣次烟叶，经过不同的加工处理，再造成具有高经济附加值及特殊使用性供卷烟使用的重组烟叶，该技术是一项具有绿色环保概念和重大社会与经济效益的高新技术，填补了卷烟工业废弃物料再利用技术的空白，改变卷烟生产“全烟叶、全烟梗”的现状。Cigarette industry regenerated tobacco sheet is the waste produced in the cigarette processing process, discarded tobacco stems, tobacco leaves and inferior tobacco leaves, through different processing, and then into recombined tobacco leaves with high economic added value and special usability for cigarettes. This technology is a high-tech with the concept of green environmental protection and significant social and economic benefits. It fills the gap in the recycling technology of waste materials in the cigarette industry and changes the current situation of "full tobacco leaves and entire tobacco stems" in cigarette production.

目前，国内外生产烟草薄片的主要方法有三种：辊压法、稠浆法和造纸法，其中造纸法烟草薄片具有烟草成分可调、燃烧性能好、焦油释放量低、产品密度小、填充性好等特点，在卷烟设计中能调整卷烟配方，不论在自身香气、降低焦油量以及提高卷烟产品物理机械等方面，都能适合加工要求，起到改善卷烟品质的重要作用，因而为卷烟生产厂家和消费者的青睐。At present, there are three main methods of producing tobacco sheets at home and abroad: roll pressing method, thick pulp method and papermaking method. Among them, the papermaking method tobacco sheet has the advantages of adjustable tobacco components, good combustion performance, low tar release, low product density, and filling properties. Good features, the cigarette formula can be adjusted in the cigarette design, no matter in terms of its own aroma, reducing the amount of tar, and improving the physical machinery of cigarette products, it can meet the processing requirements and play an important role in improving the quality of cigarettes, so it is a cigarette manufacturer. and consumers' favor.

国外烟草行业使用造纸法烟草薄片较为广泛，且造纸法烟草薄片的生产工艺也很成熟，近年来，国内烟草企业积极开展造纸法再造烟叶的生产、应用研究工作，并取得了一定的进展。The foreign tobacco industry uses paper-making tobacco sheets widely, and the production process of paper-making tobacco sheets is also very mature. In recent years, domestic tobacco companies have actively carried out research on the production and application of paper-making reconstituted tobacco leaves, and have made some progress.

中国专利CN 1274548A公开的《一种利用烟厂废料生产烟草薄片的方法》和CN 1324586A公开的《全价利用废弃及低次等烟草原料生产烟草薄片的方法》，给出一种将烟末和烟梗中经萃取、固液分离后，固体部分经制浆后制成纸基，液体部分则浓缩后回涂到纸基上的造纸法烟草薄片制备工艺，该制备工艺是一个原材料的物理重组过程，浓缩后的萃取液中的大分子化合物在制备过程中几乎不发生转化，从而导致烟草薄片存在吃味品质较差、杂气重等吸味缺陷，影响了薄片在卷烟产品中的使用效果和添加量。Chinese patent CN 1274548A discloses "A Method for Producing Tobacco Sheets Using Waste from Tobacco Factory" and CN 1324586A discloses "The Method for Producing Tobacco Sheets Using Waste and Low-grade Tobacco Raw Materials at Full Price", which provides a combination of tobacco powder and After extraction and solid-liquid separation from the tobacco stems, the solid part is pulped to make a paper base, and the liquid part is concentrated and then coated on the paper base. The paper-making tobacco sheet preparation process is a physical recombination of raw materials. During the preparation process, the macromolecular compounds in the concentrated extract hardly undergo transformation, which leads to tobacco flakes with poor taste quality, heavy miscellaneous gas and other flavor-absorbing defects, which affects the use effect of the flakes in cigarette products and the amount added.

中国专利CN 1600183A《一种造纸法烟草薄片的制备工艺》，采用酶制剂或/和微生物制剂对烟草水溶性物浓缩液进行生物降解反应，将经过降解反应的烟草水溶性物浓缩液浸涂或喷涂至烟草薄片片基上。这种方法仅对萃取后的浓缩液中的大分子物质进行降解，而片基中仍存留有大量的纤维、蛋白、果胶、淀粉等不利成分。中国专利CN1947606A《一种再造烟叶改性添加剂及其制备和使用方法》对烟梗进行生物酶处理，使果胶、蛋白质等大分子物质，降解、转化，所述专利技术没有对卷烟香气的改善进行进一步的研究，烟末所含致香成分对烟草薄片的香味有贡献作用，但所述方法也未提供对烟末的处理方案，也没有对烟梗酶处理后烟草薄片或者卷烟的降焦和改善口感及香型提出进一步的解决方案。Chinese patent CN 1600183A "Preparation process of paper-making tobacco sheet", uses enzyme preparation or/and microbial preparation to carry out biodegradation reaction on tobacco water-soluble substance concentrate, and the tobacco water-soluble substance concentrate after degradation reaction is dip-coated or Spray onto tobacco flake base. This method only degrades the macromolecular substances in the concentrated solution after extraction, while a large amount of unfavorable components such as fiber, protein, pectin and starch still remain in the film base. Chinese Patent CN1947606A "A Modified Additive for Reconstituted Tobacco Leaf and Its Preparation and Application Method" conducts biological enzyme treatment on tobacco stems to degrade and transform macromolecular substances such as pectin and protein. The patented technology does not improve the aroma of cigarettes Carrying out further research, the aromatizing components contained in the tobacco powder contribute to the aroma of the tobacco sheet, but the method does not provide a treatment plan for the tobacco powder, nor does it reduce the tar of the tobacco sheet or cigarette after the tobacco stem enzyme treatment And improve the taste and flavor to propose further solutions.

当前，在用造纸法制备烟草薄片的生产工艺中，如何降低造纸法再造烟叶的杂气含量、优化口感，增浓烟香，是众多烟草生产企业迫切希望解决的技术难题。At present, in the production process of tobacco flakes prepared by papermaking, how to reduce the miscellaneous gas content of papermaking reconstituted tobacco leaves, optimize the taste, and increase the aroma of tobacco is a technical problem that many tobacco manufacturers are eager to solve.

发明内容Contents of the invention

本发明的目的在于针对现有技术的不足，提供一种可根本上提高烟草薄片内在品质和功能性使用价值，降低烟草薄片杂气含量、优化口感，增浓烟香，并可提供多种香气类型的烟草薄片的制备方法。The purpose of the present invention is to address the deficiencies of the prior art, to provide a tobacco sheet that can fundamentally improve the intrinsic quality and functional use value of the tobacco sheet, reduce the miscellaneous gas content of the tobacco sheet, optimize the taste, increase the aroma of the tobacco, and provide a variety of aromas. A method for the preparation of types of tobacco sheet.

本发明的另一个目的在于提供由上述方法制备所得烟草薄片在卷烟生产中的应用。Another object of the present invention is to provide the application of the tobacco sheet prepared by the above method in the production of cigarettes.

本发明的上述目的是通过如下方案予以实现的：Above-mentioned purpose of the present invention is achieved by following scheme:

本发明提供一种烟草薄片的制备方法，该方法采用现有传统的造纸法，将烟草物料(如烟梗、烟末等)用水浸泡萃取，经压榨过滤，固液分离后，固体制成纤维薄片片基，液体浓缩制成涂布液，将涂布液涂布到纤维薄片片基上，烘干后切片制备得到烟草薄片，但与现有传统的造纸法不同之处在于，本发明的制备方法还包括如下两步操作：The invention provides a method for preparing tobacco flakes. The method adopts the existing traditional papermaking method, soaking and extracting tobacco materials (such as tobacco stems, tobacco powder, etc.) in water, pressing and filtering, and separating the solid and liquid, and making the solid into fiber Sheet base, the liquid is concentrated to make a coating solution, the coating solution is coated on the fiber sheet base, dried and sliced to prepare tobacco sheets, but the difference from the existing traditional papermaking method is that the present invention The preparation method also includes the following two steps:

(1)将酶加入到烟草物料浸泡液中，对烟草物料进行酶处理；(1) enzyme is added in the soaking liquid of tobacco material, and tobacco material is carried out enzyme treatment;

(2)将液体浓缩后，先向浓缩液中加入还原糖和氨基酸，使浓缩液发生美拉德反应，制备得到涂布液，再将该涂布液涂布到纤维薄片片基。(2) After concentrating the liquid, firstly add reducing sugar and amino acid to the concentrated liquid to make the concentrated liquid undergo Maillard reaction to prepare a coating liquid, and then apply the coating liquid to the fiber sheet base.

上述采用酶对烟草物料进行处理，主要是选择合适的酶以及确定酶适宜的用量、通过酶解作用将烟草物料中的大分子化合物尽可能地转化降解为小分子化合物，可降低烟草薄片杂气含量，从而改善烟草薄片的内在品质；所述复合酶可选择复合蛋白酶、复合果胶酶、中性纤维素酶、木聚糖酶或糖化酶中的一种或任意两种以上；所述复合蛋白酶、复合果胶酶、中性纤维素酶、木聚糖酶或糖化酶均有成品销售，可从市场购买获得。The above-mentioned treatment of tobacco materials with enzymes is mainly to select appropriate enzymes and determine the appropriate amount of enzymes, and convert and degrade the macromolecular compounds in the tobacco materials into small molecular compounds as much as possible through enzymatic hydrolysis, which can reduce the miscellaneous air in tobacco sheets. content, thereby improving the intrinsic quality of tobacco flakes; the compound enzyme can be selected from one or more of compound protease, compound pectinase, neutral cellulase, xylanase or glucoamylase; the compound Protease, compound pectinase, neutral cellulase, xylanase or glucoamylase are sold as finished products and can be purchased from the market.

美拉德反应是一种羰基-氨基反应，这种反应会引起物质色泽的改变，同时产生香气，但现有技术未见利用美拉德反应改善烟草香气或者通过改变美拉德反应条件获得不同香型烟草薄片的技术报道，本发明将美拉德反应引入造纸法烟草薄片制备工艺中，利用酶处理和美拉德反应所产生的香气赋予烟草薄片浓郁的香味。并通过长期大量的实验研究总结出合适和精确的美拉德反应条件，获得更优的产品品质；通过确定向浓缩液中外加不同的反应料(不同的还原糖和氨基酸)进行美拉德反应产生预期香气的技术方案，适应不同风格卷烟产品的要求。The Maillard reaction is a carbonyl-amino reaction, which can cause a change in the color of the substance and produce aroma, but in the prior art, there is no use of the Maillard reaction to improve the aroma of tobacco or to obtain different tobacco aromas by changing the Maillard reaction conditions. A technical report on flavored tobacco sheets, the present invention introduces the Maillard reaction into the papermaking tobacco sheet preparation process, and uses the enzyme treatment and the aroma produced by the Maillard reaction to endow the tobacco sheet with a strong fragrance. And through a large number of long-term experimental studies, the appropriate and accurate Maillard reaction conditions have been summarized to obtain better product quality; by adding different reaction materials (different reducing sugars and amino acids) to the concentrate to carry out the Maillard reaction The technical scheme for producing expected aroma is adapted to the requirements of different styles of cigarette products.

上述制备方法中，烟草物料优选烟梗和烟末的混合物，通过烟梗和烟末搭配不同的处理方案获得改善烟草薄片纤维片基和香味等品质的良好效果。In the above-mentioned preparation method, the tobacco material is preferably a mixture of tobacco stems and tobacco dust, and different treatment schemes are combined with tobacco stems and tobacco dust to obtain good effects of improving the quality of the tobacco sheet fiber base and flavor.

本发明采用的烟草物料中包含的主要成分为烟梗和烟末，烟梗主要含有纤维物质及果胶、糖、淀粉和少量致香成分，烟末中含有大量致香成分及纤维物质，在目前的烟草生产工厂，因为烟梗和烟末被废弃不用，所以导致烟叶中纤维物质、致香成分等不能得到充分的利用；同时，因为烟梗和烟末所含纤维物质、致香成分不同，因此本发明将两种物质分开进行处理，确定不同的处理方案，针对性地将两种物质中的有用物质充分提炼出来，并寻找到二者比较优选的搭配比例。The main components contained in the tobacco material used in the present invention are tobacco stems and tobacco powder. The tobacco stems mainly contain fibrous substances, pectin, sugar, starch and a small amount of aroma components. In the current tobacco production factory, because the tobacco stems and tobacco powder are discarded, the fiber substances and aroma components in the tobacco leaves cannot be fully utilized; at the same time, because the tobacco stems and tobacco powder contain different fiber substances and aroma components , so the present invention treats the two substances separately, determines different treatment schemes, fully extracts the useful substances from the two substances, and finds a more preferable matching ratio of the two substances.

本发明的制备方法具体包括如下步骤：The preparation method of the present invention specifically comprises the following steps:

(1)将烟梗打磨去皮后用水浸泡，得到烟梗浸泡液，向该烟梗浸泡液中加入酶，酶解处理后萃取；(1) Grinding and peeling the tobacco stems and soaking them in water to obtain a tobacco stem soaking solution, adding enzymes to the tobacco stem soaking solution, enzymatically treating and extracting;

将烟末用水浸泡，得到烟末浸泡液，向该烟末浸泡液中加入酶，酶解处理后萃取；soaking the tobacco powder in water to obtain a tobacco powder soaking solution, adding enzymes to the tobacco powder soaking solution, enzymolysis treatment and extraction;

(2)将步骤(1)萃取液分别依次进行压榨过滤、固液分离处理；(2) Squeeze and filter the extract in step (1) and perform solid-liquid separation successively;

(3)将步骤(2)烟梗处理分离所得固体、烟末处理分离所得固体分别分散于水中，打浆解纤，解纤后再合并配浆，纤维帚化得烟草纤维，烟草纤维脱水干燥后制成纤维薄片片基；(3) Disperse the solid obtained from the treatment and separation of the tobacco stems in step (2) and the solid obtained from the treatment and separation of the tobacco powder in water respectively, beating and defibrating, and then combining and preparing the pulp after defibrating, and the fiber is broomed to obtain tobacco fibers, and the tobacco fibers are dehydrated and dried Made into a fiber sheet base;

合并步骤(2)分离所得液体，浓缩得浓缩液，向浓缩液中加入还原糖和氨基酸，使浓缩液进行美拉德反应，制备得到涂布液；In the merging step (2), the obtained liquid is separated and concentrated to obtain a concentrated liquid, adding reducing sugars and amino acids to the concentrated liquid, and subjecting the concentrated liquid to a Maillard reaction to prepare a coating liquid;

(4)将步骤(3)制备所得涂布液涂布到纤维薄片片基上，干燥后得到烟草薄片。(4) Coating the coating liquid prepared in step (3) on the fiber sheet base, and drying to obtain a tobacco sheet.

上述制备方法中，所述烟梗的打磨去皮用水浸泡、烟末用水浸泡、萃取、压榨过滤萃取液、固液分离处理和将烟草纤维制成纤维薄片片基等基本操作可参照常规造纸法生产烟草薄片方法，例如萃取，可采用常规工艺单次提取、常规多次提取以及连续逆流提取。但作为优选，本发明所述萃取采用三级逆流罐式提取工艺，对每一份烟草物料(烟梗或烟末)进行三次提取，依次用二次提取液、一次提取液和水作为提取剂；每一份提取剂对三份梗进行提取，分别是二次提取梗或末、一次提取梗或末和新的梗或末，即对物料中水溶性成分提取完全，又不会对设备提出新的特殊要求，能将单级提取工艺35％的提取率提高到50％。萃取温度优选为50℃～80℃，萃取时间为30～60min，既能确保可溶性物质的提取，又降低能源消耗，而且有效避免香气成分的损失，保持造纸法再造烟叶产品的品质。为了筛选确定烟草物料与水溶剂的配比，我们做了大量的实验研究，总结出既保证原料可溶性物质完全提取，又有利于节约能源的最佳比例是：将烟梗打磨去皮后用水浸泡，烟末直接用水浸泡，采用的固液比为1∶5～1∶15(Kg∶L)。向该烟梗浸泡液中加入酶，酶的加入量为烟梗总质量的0.05％～5％，酶解温度为20～50℃，搅拌速度为5～60rmp，酶解时间为1～8小时。In the above preparation method, basic operations such as grinding and peeling the tobacco stems, soaking the tobacco stems in water, soaking the tobacco powder in water, extracting, pressing and filtering the extract, solid-liquid separation treatment, and making tobacco fibers into fiber sheets can refer to conventional papermaking methods. Tobacco sheet production methods, such as extraction, can use conventional single extraction, conventional multiple extraction and continuous countercurrent extraction. But as a preference, the extraction of the present invention adopts a three-stage countercurrent tank type extraction process, and each part of tobacco material (tobacco stem or tobacco powder) is extracted three times, and the secondary extraction solution, the primary extraction solution and water are used as the extraction agent in turn. ;Each extractant extracts three stems, which are the second extraction stem or end, the first extraction stem or end and the new stem or end, that is, the water-soluble components in the material are completely extracted, and the equipment will not be raised. The new special requirement can increase the extraction rate of single-stage extraction process from 35% to 50%. The extraction temperature is preferably 50°C to 80°C, and the extraction time is 30 to 60 minutes, which can not only ensure the extraction of soluble substances, but also reduce energy consumption, effectively avoid the loss of aroma components, and maintain the quality of papermaking reconstituted tobacco products. In order to screen and determine the ratio of tobacco material and water solvent, we have done a lot of experimental research, and concluded that the best ratio that not only ensures the complete extraction of soluble substances in raw materials, but also helps to save energy is: polish and peel the tobacco stems and soak them in water , the tobacco powder is directly soaked in water, and the solid-to-liquid ratio used is 1:5 to 1:15 (Kg:L). Add enzyme to the tobacco stem soaking liquid, the amount of enzyme added is 0.05%-5% of the total mass of tobacco stems, the enzymolysis temperature is 20-50°C, the stirring speed is 5-60rmp, and the enzymolysis time is 1-8 hours .

上述步骤(1)中，将烟末用水浸泡，所得烟末浸泡液的固液比为1∶5～1∶15(Kg∶L)，向该烟末浸泡液中加入酶，酶的加入量为烟末总质量的0.05％～5％，酶解处理时温度为20～50℃，搅拌速度为5～60rmp，酶解时间为1～8小时。In the above step (1), the tobacco powder is soaked in water, and the solid-to-liquid ratio of the obtained tobacco powder soaking solution is 1:5 to 1:15 (Kg:L), and enzymes are added to the tobacco powder soaking solution, and the amount of the enzyme added is The content is 0.05%-5% of the total mass of tobacco dust, the temperature during enzymolysis treatment is 20-50° C., the stirring speed is 5-60 rpm, and the enzymolysis time is 1-8 hours.

上述步骤(1)中，因为烟梗含有大量的纤维以及少量的致香成分，因此对烟梗进行步骤(1)的处理后，其纤维成分被提炼出来用于后续的纤维薄片片基制备，而烟梗中含有的果胶、糖、淀粉和少量致香成分则被用于后续的涂布液制备；烟末虽然含有的纤维成分较少，但是烟末含有大量的致香成分，经过步骤(1)的处理后，其致香成分被提炼出来用于后续的涂布液制备，而含有的少量纤维成分也可用于纤维薄片片基制备；本发明通过大量实验总结得到，烟梗和烟末的质量比优选为3∶1～1∶3，可获得很好的致香效果和片基质量。In the above step (1), because the tobacco stem contains a large amount of fiber and a small amount of aroma components, after the treatment of the tobacco stem in step (1), its fiber component is extracted for the subsequent preparation of the fiber sheet base, The pectin, sugar, starch and a small amount of aroma components contained in the tobacco stems are used in the subsequent preparation of the coating solution; although the tobacco powder contains less fiber components, the tobacco powder contains a large amount of aroma components. After the treatment of (1), its aroma-causing components are extracted for the subsequent preparation of the coating solution, and the small amount of fiber components contained can also be used for the preparation of the fiber sheet base; The mass ratio of powder is preferably 3:1-1:3, which can obtain good aroma effect and film base quality.

烟草薄片片基的吸收性能直接关系到涂布量的大小和产品的稳定性。叶片经提取后，特别容易被打碎，如果打浆程度太高，叶片细碎，就有可能在很大程度上降低片基的疏松性能，降低片基的吸收性能。本发明在上述步骤(3)中，对烟梗处理分离所得的固体采取三级解纤处理，一次解纤的叩解度为10～25°SR，二次解纤叩解度为13～26°SR，最后进入成品浆烟梗纤维的叩解度为14～35°SR；对烟末处理分离所得的固体采取二级解纤处理即可，一次解纤叩解度为10～25°SR，二次解纤叩解度为13～26°SR。分别解纤处理后进行混合按照常规进行纤维帚化操作得到烟草纤维片基，优选片基水分含量为25～35％；为了提高烟草薄片的物理性能，通常采用外加针木木桨纤维(该类纤维具有纤维长，杂气较少的特点)的方法来实现，木浆纤维的加入量一般为2～10％(干物质百分比)，加入量越高则物理性能越好，但杂气会越大，本发明人通过实践发现木浆纤维的加入量控制在3～5％可达到较平衡。The absorption performance of the tobacco sheet base is directly related to the size of the coating amount and the stability of the product. After the leaves are extracted, they are particularly easy to be broken. If the degree of beating is too high, the leaves will be finely broken, which may greatly reduce the looseness of the film base and reduce the absorption performance of the film base. In the above step (3), the present invention adopts three-stage defibration treatment on the solid obtained from tobacco stem treatment and separation, the degree of defibration for the first defibration is 10-25°SR, and the degree of defibration for the second defibration is 13-26°SR , and finally the beating degree of tobacco stem fibers entering the finished pulp is 14-35°SR; the solid obtained from the separation of tobacco powder treatment can be treated by two-stage defibrating treatment, the first-time defibrating degree is 10-25°SR, Fiber percussion degree of 13 ~ 26 ° SR. After the defibrillation treatment, mix them according to the conventional fiber brooming operation to obtain the tobacco fiber sheet base, preferably the moisture content of the sheet base is 25% to 35%; in order to improve the physical properties of the tobacco sheet, usually add needlewood wood pulp fiber (this kind The fiber has the characteristics of long fiber and less miscellaneous gas) to achieve it. The amount of wood pulp fiber is generally 2 to 10% (percentage of dry matter). The higher the amount, the better the physical properties, but the more the miscellaneous gas will be Large, the inventors have found through practice that the addition of wood pulp fibers can be controlled at 3-5% to achieve a more balanced.

上述步骤(3)中，合并步骤(2)分离所得液体，在将该液体进行浓缩前，可先加入乙醇，乙醇的作用是沉淀合并所得液体中的大分子物质，乙醇的加入量为合并所得液体体积的1～3倍。In the above-mentioned step (3), the liquid obtained in the merging step (2) is separated. Before the liquid is concentrated, ethanol can be added earlier. The effect of ethanol is to precipitate and merge the macromolecular substances in the obtained liquid. 1 to 3 times the volume of the liquid.

上述步骤(3)中，浓缩可采用现有的直接加热常压蒸发浓缩法、间接加热常压蒸发浓缩法、间接加热真空浓缩法对提取液进行浓缩，将液体浓缩至固形物含量为10～50％即可。本发明优选采用真空浓缩法进行浓缩，不加热。向浓缩液中加入还原糖和氨基酸，加热使浓缩液发生美拉德反应；美拉德反应条件为：还原糖的加入量为浓缩液质量的2.5％～10％，还原糖为木糖、核糖、阿拉伯糖、葡萄糖、果糖、甘露糖、半乳糖其中一种或任意两种以上的混合物；氨基酸的加入量为浓缩液质量的2.5％～10％，氨基酸为甘氨酸、亮氨酸、谷氨酸、脯氨酸、精氨酸、天门冬氨酸、苯丙氨酸其中一种或任意两种以上的混合物；调节美拉德反应总体系pH为6～8，美拉德反应温度为85℃～130℃，机械搅拌反应1～2小时；所述美拉德反应体系中还可以加入微量的维生素C(Vc)或丙二醇，加入量优选0.1％。In the above step (3), the extraction can be concentrated by using the existing direct heating atmospheric pressure evaporation concentration method, indirect heating atmospheric pressure evaporation concentration method, indirect heating vacuum concentration method, and the liquid is concentrated to a solid content of 10 ~ 50% will do. The present invention preferably adopts vacuum concentration method to concentrate without heating. Add reducing sugars and amino acids to the concentrated solution, heat the concentrated solution to undergo Maillard reaction; the Maillard reaction conditions are: the amount of reducing sugar added is 2.5% to 10% of the concentrated solution mass, and the reducing sugars are xylose and ribose , arabinose, glucose, fructose, mannose, galactose, or a mixture of any two or more; the amount of amino acids added is 2.5% to 10% of the mass of the concentrate, and the amino acids are glycine, leucine, and glutamic acid , proline, arginine, aspartic acid, phenylalanine or a mixture of any two or more; adjust the overall pH of the Maillard reaction system to 6-8, and the Maillard reaction temperature to 85°C ～130°C, mechanically stirring for 1～2 hours; a small amount of vitamin C (Vc) or propylene glycol may also be added to the Maillard reaction system, preferably 0.1%.

上述步骤(4)中，涂布到纤维薄片片基上的涂布液温度为50～60℃，涂布液20℃时密度为1.200g/cm³，涂布液20℃时粘度为0.01Pa.s。In the above step (4), the temperature of the coating liquid coated on the fiber sheet base is 50-60°C, the density of the coating liquid at 20°C is 1.200g/cm³ , and the viscosity of the coating liquid at 20°C is 0.01Pa .s.

根据实际需要，可重复步骤(4)，将每次得到的烟草薄片再次涂布步骤(3)所得涂布液，优选重复3次，然后将最后得到的烟草薄片切片，包装入库即可。According to actual needs, step (4) can be repeated, and the coating solution obtained in step (3) is re-coated with the tobacco sheet obtained each time, preferably repeated 3 times, and then the tobacco sheet obtained at last is sliced and packaged for storage.

通过酶解作用将烟草物料中的大分子化合物充分转化降解为小分子化合物，经固液分离处理后所得的纤维浆料含蛋白质、果胶等杂质成分很少，故既能有效地提高薄片片基的膨松度又能降低片基的杂气含量，从而为改善烟草薄片的内在品质提供良好的基础；所得液体能为美拉德反应提供更多的还原糖及氨基酸为美拉德反应创造良好的糖氨反应基础条件，经美拉德反应所制得涂布液，具有产生的更多香气并赋予烟草薄片浓郁的香味。The macromolecular compounds in the tobacco material are fully converted and degraded into small molecular compounds by enzymatic hydrolysis, and the fiber slurry obtained after solid-liquid separation contains very little impurity components such as protein and pectin, so it can effectively improve the quality of flakes.

具体实施方式Detailed ways

下面结合具体实施例对本发明做进一步详细的说明。The present invention will be described in further detail below in conjunction with specific embodiments.

实施例1烟草薄片制备条件的选择实验The selection experiment ofembodiment 1 tobacco sheet preparation conditions

1、萃取条件的选择1. Selection of extraction conditions

提取烟草废弃物的方法可有多种，如添加适宜的化学药品法或冷、热水直接法等，为了保证烟草有效成分的品质少受破坏以及实现尽可能多地回收利用，提取方法的选择十分重要。本发明采用萃取，实际上是采用一种三级逆流提取工艺。There are many ways to extract tobacco waste, such as adding appropriate chemicals or direct cold and hot water. In order to ensure that the quality of tobacco active ingredients is less damaged and to achieve as much recycling as possible, the choice of extraction method very important. The present invention adopts extraction, which actually adopts a three-stage countercurrent extraction process.

每一份梗进行三次提取，依次用二次提取液、一次提取液和水作为提取剂；每一份提取剂对三份梗进行提取，分别是二次提取梗、一次提取梗和新梗。Each part of the stem is extracted three times, and the secondary extraction solution, the first extraction solution and water are used as the extractant in turn; each part of the extraction agent is used to extract three parts of the stem, which are the second extraction stem, the first extraction stem and the new stem.

对每一份梗和每一份提取剂各步骤提取率进行研究，并以一次提取液为对照。同一原料三次提取的提取率依次降低，结果见表1所示：The extraction rate of each step of each stalk and each extract was studied, and one extraction was used as a control. The extraction rate of the three extractions of the same raw material decreases successively, and the results are shown in Table 1:

表1提取率比较Table 1 Comparison of extraction rates

从总提取率的平均趋势来看，经过三次提取后的梗有50％左右的绝干物质被提取出来，而提取过三次梗的提取液固含量也达到50％左右，故可以认为该工艺条件下梗的提取率为50％左右，比起现有常规工艺的提取率35％左右有较大提高。每一份梗要经过3次提取，提取时间增加，第一级提取时间为30分钟，第二级提取时间为25分钟，第三级提取时间为25分钟，但由于三级提取同时进行，除了刚开始运行时的非正常阶段，每一份梗实际提取耗时较少，比现有常规工艺缩短了大概20％。从下文所述实施例制备掺烟草薄片卷烟评吸结果来看，其抽吸品质与现有常规工艺所得薄片在杂气、刺激方面略有改善，不会影响造纸法再造烟叶产品的抽吸品质，但本发明方法能保证可溶性物质的高效提取，同时也是最有效的节能降耗的方法。Judging from the average trend of the total extraction rate, about 50% of the absolute dry matter is extracted from the stems after three extractions, and the liquid-solid content of the stems extracted three times also reaches about 50%, so it can be considered that the process conditions The extraction rate of the lower stem is about 50%, which is greatly improved compared with the extraction rate of about 35% in the existing conventional process. Each stalk needs to be extracted 3 times, and the extraction time increases. The first-level extraction time is 30 minutes, the second-level extraction time is 25 minutes, and the third-level extraction time is 25 minutes. However, since the three-level extraction is carried out at the same time, except In the abnormal stage at the beginning of operation, the actual extraction time of each stem is less, which is about 20% shorter than the existing conventional process. Judging from the smoking evaluation results of tobacco-infused sheet cigarettes prepared in the examples described below, its smoking quality is slightly improved in terms of miscellaneous gas and stimulation compared with the sheet obtained by the existing conventional technology, and will not affect the smoking quality of reconstituted tobacco leaf products by papermaking method , but the method of the present invention can ensure efficient extraction of soluble substances, and is also the most effective method of saving energy and reducing consumption.

本实施例选定不同温度来考察萃取的最佳温度。大量实验总结得到，温度太低不能保证可溶性物质的提取，而且温度较低时必须延长提取时间，才能保证提取的得率；温度过高，并不能明显提高提取物的得率，反而增加热能消耗和香气物质的损耗。结果表明，在50℃～80℃的温度下，萃取30～60min，既能确保可溶性物质的提取，降低能源消耗，又避免香气成分的损失，保持造纸法再造烟叶产品的品质。In this embodiment, different temperatures are selected to investigate the optimum temperature for extraction. A large number of experiments have concluded that the extraction of soluble substances cannot be guaranteed if the temperature is too low, and when the temperature is low, the extraction time must be extended to ensure the extraction yield; if the temperature is too high, the extraction yield cannot be significantly increased, but the heat energy consumption will be increased and loss of aroma substances. The results showed that extraction at a temperature of 50°C to 80°C for 30 to 60 minutes could not only ensure the extraction of soluble substances, reduce energy consumption, but also avoid the loss of aroma components and maintain the quality of reconstituted tobacco leaves produced by papermaking.

2、浓缩方法的选择2. Selection of concentration method

对烟梗提取液采用直接加热常压蒸发浓缩法、真空浓缩法对提取液进行了浓缩处理，表2中列出了直接加热常压蒸发浓缩法和真空浓缩法所得浓缩液的主要化学成分。The tobacco stem extract was concentrated by direct heating atmospheric pressure evaporation concentration method and vacuum concentration method. Table 2 lists the main chemical components of the concentrated liquid obtained by direct heating atmospheric pressure evaporation concentration method and vacuum concentration method.

表2在不同浓缩条件下的浓缩液的化学成分Table 2 The chemical composition of the concentrate under different concentration conditions

检测项目 Test items 直接加热常压浓缩法Direct heating atmospheric pressure concentration method 真空浓缩法Vacuum concentration method 提取液体积(ml)Extract volume (ml) 50005000 50005000 总糖％Total sugar % 5.105.10 4.764.76 总烟碱％Total Nicotine % 0.7670.767 0.7060.706 挥发性总量(％)Total volatility (%) 7878 8080 浓缩时间(min)Concentration time (min) 120120 4545 浓缩物密度(g/m³)Concentrate density (g/m³ ) 1.201.20 1.201.20

从表2中的数据可以看出采用真空浓缩法时，浓缩液中总糖和总烟碱的浓度较其它两种方法低，而且达到规定浓度时所需要的时间较短，同时，采用真空浓缩时，可适当降低浓缩温度，进行低温蒸发对于保持烟草有效成分的芳香品质具有积极的意义。It can be seen from the data in Table 2 that when the vacuum concentration method is adopted, the concentration of total sugar and total nicotine in the concentrated solution is lower than that of the other two methods, and the time required to reach the specified concentration is shorter. At this time, the concentration temperature can be appropriately lowered, and low-temperature evaporation is of positive significance for maintaining the aroma quality of tobacco active ingredients.

3、打浆方法的选择3. Selection of beating method

根据打浆过程对烟梗机械作用的强弱不同，设计四个过程：According to the strength of the mechanical action of the beating process on the tobacco stems, four processes are designed:

(1)轻刀打浆，用轻刀将烟梗纤维疏解开来，打浆时间较长。(1) Beating with a light knife, the tobacco stem fibers are loosened with a light knife, and the beating time is longer.

(2)重刀打浆，用重刀将烟梗纤维打散，打浆时间较短。(2) Heavy knife beating, the tobacco stem fibers are broken up with a heavy knife, and the beating time is short.

(3)先用重刀将烟梗纤维切断到一定程度，再换用轻刀将烟梗纤维疏解开。(3) First cut off the tobacco stem fiber to a certain extent with a heavy knife, and then use a light knife to loosen the tobacco stem fiber.

(4)先用重刀将烟梗纤维切断到一定程度，再换用轻刀将烟梗纤维疏解开，将叶的打浆度提高。(4) Cut off the tobacco stem fibers to a certain extent with a heavy knife first, and then use a light knife to loosen the tobacco stem fibers to improve the beating degree of the leaves.

第(1)、(2)、(3)组实验采用叶打浆度15°SR，第(4)组试验中梗的打浆过程跟第三组试验一样，只是将叶的打浆度由15°SR提高到了25°SR。各组试验所制的浆料，分别与外加纤维按一定的比例(按干物质百分比，外加4～10％的针木木浆纤维)抄造成片基，检测片基的各项物理性能，并分析制浆过程与片基性能的关系。实验工艺参数结果见表3，(检测方法为国标)。The first (1), (2), (3) group experiments adopt leaf beating degree 15 ° SR, the beating process of the stem in the (4) group test is the same as the third group of experiments, just the beating degree of leaves is changed from 15 ° SR Increased to 25° SR. The pulp prepared by each group of tests was copied with the added fiber in a certain proportion (according to the percentage of dry matter, plus 4-10% needle wood pulp fiber) to form a film base, and the physical properties of the film base were tested. The relationship between the pulping process and the properties of the sheet base was analyzed. The results of the experimental process parameters are shown in Table 3, (the detection method is the national standard).

表3梗打浆工艺参数实验结果Table 3 Experimental results of beating process parameters of stems

片基抗张强度与打浆程度的关系实验结果见表4和附图2(图2中，四条曲线分别为烟梗编号1～4的片基扩张强度与打浆程度关系曲线)：The experimental results of the relationship between the tensile strength of the film base and the degree of beating are shown in Table 4 and accompanying drawing 2 (in Figure 2, the four curves are respectively the relationship curves between the expansion strength of the film base and the degree of beating oftobacco stem numbers 1 to 4):

表4抗张强度与打浆程度的关系The relation of table 4 tensile strength and degree of beating

烟梗编号Tobacco stem number 第(1)组试验Group (1) test 第(2)组试验Group (2) test 第(3)组试验Group (3) test 第(4)组试验Group (4)test 1# 1# 0.4240.424 0.4230.423 0.4890.489 0.5630.563 2# 2# 0.4900.490 0.4870.487 0.620.62 0.710.71 3#3# 0.5570.557 0.5550.555 0.6650.665 0.7330.733 4#4# 0.6910.691 0.6530.653 0.6960.696 0.8000.800

由实验可知，片基抗张强度不仅与打浆度有关系，与打浆过程关系也非常密切。打浆度提高，抗张强度升高。打浆度提高纤维尺寸减小，纤维间的交织空隙减小，强度也相应增加。但这是以片基疏松性减小作为代价的。第(1)组试验和第(2)组试验的抗张强度几乎相等。这说明用轻刀长时间磨浆与用重刀短时间磨浆，成浆的结合强度相当。第(3)组试验，是先用重刀将烟梗纤维切断到一定程度，然后用轻刀将纤维疏解开来。用这组试验的浆料抄出的片基抗张强度最大，浆料质量较理想。It can be seen from the experiment that the tensile strength of the film base is not only related to the degree of beating, but also closely related to the beating process. The degree of beating is increased, and the tensile strength is increased. As the beating degree increases, the fiber size decreases, the interweaving gap between fibers decreases, and the strength increases accordingly. But this comes at the expense of reduced substrate porosity. The tensile strengths of group (1) test and group (2) test are almost equal. This shows that refining with a light knife for a long time and refining with a heavy knife for a short time have the same bonding strength. The (3) group test is to cut off the tobacco stem fiber to a certain extent with a heavy knife earlier, and then loosen the fiber with a light knife. The sheet base produced with the slurry of this group of tests has the highest tensile strength, and the quality of the slurry is ideal.

透气度与打浆程度的关系实验结果见表5和附图3(图3中，四条曲线分别为烟梗编号1～4的片基透气度与打浆程度关系曲线)。The experimental results of the relationship between air permeability and beating degree are shown in Table 5 and accompanying drawing 3 (in Fig. 3, the four curves are respectively the relationship curves between air permeability and beating degree oftobacco stem numbers 1 to 4).

透气度与造纸法再造烟叶的燃烧性能关系密切，透气度大燃烧性能相对较好。从附图3显示，第(1)组试验的透气度最好，第(4)组试验的透气性能较差，叶浆在较大打浆度下，被打的细碎，填塞了梗浆纤维间的缝隙，透气性能降低。The air permeability is closely related to the combustion performance of reconstituted tobacco leaves by papermaking method, and the combustion performance is relatively better if the air permeability is large. Shown from accompanying drawing 3, the air permeability of the (1) group test is the best, the air permeability of the (4) group test is relatively poor, and the leaf pulp is beaten finely under the larger degree of beating, filling the space between the stem pulp fibers gaps, the air permeability is reduced.

片基吸收性能与打浆程度的关系实验结果见表6、表7和附图4(图4中，四条曲线分别为烟梗编号1～4的片基吸水率与打浆程度关系曲线)、附图5(图5中，四条曲线分别为烟梗编号1～4的片基表面吸收性能与打浆程度关系曲线)：See table 6, table 7 and accompanying drawing 4 (in figure 4, four curves are the relationship curves of the water absorption rate of the film base and beating degree oftobacco stem numbers 1 to 4 respectively) and accompanying drawing 5 (In Fig. 5, the four curves are the relationship curves between the surface absorption performance of the tobacco stem number 1-4 and the beating degree):

片基的吸收性能用吸水率和表面吸水性能两个指标表示。吸水率表示的是水在纸条上的上升速率，单位为毫米/秒(mm/S)。表面吸水性能为一个液滴被片基表面完全吸收的时间，单位为秒(S)。用这两个指标综合考虑片基对涂布料液的吸收性能。The absorption performance of the film base is expressed by two indicators: water absorption rate and surface water absorption performance. The water absorption rate indicates the rising rate of water on the paper strip, in millimeters per second (mm/S). The surface water absorption performance is the time for a droplet to be completely absorbed by the surface of the film base, in seconds (S). These two indicators are used to comprehensively consider the absorption performance of the film base to the coating liquid.

从总体来看，片基的吸收性能随着打浆度的提高而降低。第(1)组试验的吸收性能较好，第(4)组实验的吸收性能较差，这与透气度试验的结果也相吻合。片基的吸收性能直接关系到涂布量的大小和产品的稳定性。In general, the absorption performance of the sheet base decreases with the increase of beating degree. The absorption performance of the group (1) test is better, and the absorption performance of the group (4) test is poor, which is also consistent with the results of the air permeability test. The absorption performance of the film base is directly related to the size of the coating amount and the stability of the product.

基于以上的研究，我们选择采用高浓盘磨、中浓盘磨、疏解机、精浆机的合理搭配和优化组合，充分利用中高浓盘磨的使用对原料纤维的切断较小，纤维分丝、细纤维化较好的特点，浆料质量较高，有利于片基成型，提高了纤维的柔韧性和成纸性；精浆机和疏解机的使用使得纤维的长度更加均匀，减少纸病，成纸匀度较好，对后续涂布工艺中涂布量的均匀稳定起到关键作用，保证再造烟叶的品质更加稳定，使造纸法再造烟叶成品具有一定的强度，并且柔软性和耐加工性较好。Based on the above research, we choose to use the reasonable collocation and optimized combination of high-consistency disc mill, medium-consistency disc mill, deflaker and refiner, and make full use of the use of medium-high-consistency disc mill to reduce the cutting of raw material fibers and reduce fiber separation. , good fine fiber characteristics, high pulp quality, which is conducive to the formation of the base, improving the flexibility and paper-forming properties of the fiber; the use of the refiner and deflaker makes the length of the fiber more uniform and reduces paper defects , better paper evenness, plays a key role in the uniformity and stability of the coating amount in the subsequent coating process, ensures more stable quality of reconstituted tobacco leaves, and makes the finished papermaking reconstituted tobacco leaves have a certain strength, flexibility and processing resistance sex is better.

上述表10中是依据中华人民共和国国家标准GB 5606.4-2005《卷烟第4部分：感官技术要求》进行感官检验得出，对照组2的配伍性较差影响了香气且欠协调，杂气稍显露，口腔有滞舌和刺激性稍较增大，造成品质有所下降，而当掺配实施例4烟草薄片且比例在5~25％时，S牌号卷烟风格保持良好，卷烟内质得分提高，卷烟吸食的口感改善，烟香协调，随着掺配比例的增加，S牌号产品风格会逐渐发生变化，会稍显烟草薄片的吃味风格，但燃吸品质并无明显变差。The above Table 10 is based on the sensory test conducted according to the national standard of the People's Republic of China GB 5606.4-2005 "Cigarette Part 4: Sensory Technical Requirements". , the oral cavity has stagnant tongue and slightly increased irritation, resulting in a decline in quality, and when the tobacco sheet of Example 4 is blended at a ratio of 5-25%, the style of S brand cigarettes remains good, and the internal quality score of the cigarettes increases. The taste of cigarette smoking is improved, and the smoke aroma is coordinated. With the increase of the blending ratio, the style of the S brand product will gradually change, and the taste style of tobacco flakes will be slightly revealed, but the smoking quality does not deteriorate significantly.
