本发明涉及造纸法再造烟叶领域，具体是一种提高造纸法再造烟叶品质的保香方法。The invention relates to the field of reconstituted tobacco leaves by papermaking method, in particular to a method for preserving fragrance by improving the quality of reconstituted tobacco leaves by papermaking method.
背景技术Background technique
造纸法再造烟叶的制备过程中，为了确保上机物理强度的要求，通常会在原料配方中添加10％左右的植物纤维来提高片基强度，另一方面由于碎片原料紧张，有时也使用一些低次的级外烟叶，因此会给产品带来刺激性、木质气、舒适性等方面的缺陷，这些缺陷主要是通过加香加料的方法进行掩盖。而涂布后的干燥加工是保香的一道关键而重要的工序，涂布液中挥发性、半挥发性致香成分在干燥过程中易挥发损失，而影响产品的感官质量。现有技术中，通常是将浓缩液与香精香料混合配料后进行表面施胶或夹网等单次涂布，涂布后进行高温热风穿透干燥，通常干燥热风温度高达120℃以上，易造成挥发性致香成分的大量损失，查阅相关资料显示，造纸法再造烟叶在涂布后的干燥过程中致香成分的损失高达20％-30％，给产品感官质量带来较大的负面影响，另一方面，浓缩液与香精香料混合添加方式，存在涂布液体系互溶性较差而带来的涂布均匀性以及涂布液渗透性等方面的问题，易导至产品出现粘连结块等质量问题。In the preparation process of reconstituted tobacco leaves by papermaking method, in order to ensure the physical strength requirements of the machine, about 10% plant fibers are usually added to the raw material formula to improve the strength of the sheet base. Therefore, it will bring defects such as irritation, woodiness and comfort to the product, and these defects are mainly covered up by adding flavors and ingredients. The drying process after coating is a key and important process for maintaining fragrance. The volatile and semi-volatile aroma components in the coating solution are easy to volatilize and lose during the drying process, which affects the sensory quality of the product. In the prior art, the concentrated liquid is usually mixed with flavors and fragrances, and then the surface is sizing or sandwiched for a single coating. After coating, high-temperature hot air penetration drying is carried out. Usually, the temperature of the drying hot air is as high as 120°C, which is easy to cause A large amount of volatile aroma components are lost. According to relevant information, the loss of aroma components in paper-making reconstituted tobacco leaves is as high as 20%-30% during the drying process after coating, which has a relatively large negative impact on the sensory quality of the product. On the other hand, the mixed addition method of concentrated liquid and flavors and fragrances has problems in coating uniformity and coating liquid permeability caused by poor miscibility of the coating liquid system, which can easily lead to sticking and caking of the product. Quality issues.
提高造纸法再造烟叶品质的相关报道有很多，但从加料方式和干燥温度控制上来减少致香成分损失的方法，未见相关报道。There are many related reports on improving the quality of reconstituted tobacco leaves by the papermaking method, but there are no relevant reports on the method of reducing the loss of aroma components from the feeding method and drying temperature control.
