Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural fat or oil containing docosahexaenoic acid (hereinafter abbreviated as DHA) at a high concentration. [0002] Natural oils and fats, which are glycerides containing ω3 polyunsaturated fatty acids, are often contained in fish oils and the like in the form of triglycerides. In particular, DHA is known to have useful physiological activities such as improvement of learning function, anti-atherosclerosis, anti-tumor, immunostimulation, and anti-allergy. This DHA
Natural fats and oils, which are naturally occurring glycerides, contain at most 20 to 30% of the constituent fatty acids. In addition, large amounts of saturated fatty acids such as palmitic acid and stearic acid and ω6 represented by linoleic acid Since these natural fats and oils are used as health foods and pharmaceuticals, they are inconvenient in terms of lipid excess because they contain system unsaturated fatty acids. For this, D
Fats and oils reduced in fatty acids other than HA were prepared by an enzymatic method (Yukihisa Tanaka et a).
1, Journal of American Oil
Chemical Society, 69, (199
2) 1210-1214). [0003] Further, a report on a high-concentration DHA oil / fat prepared by using a lipase synthesis reaction using free high-purity DHA and glycerin as raw materials or a transesterification reaction of lipase with high-purity DHA ethyl ester (Tanaka). Yukihisa et al., Oil Chemistry, 41, 1992, pp. 563-567 and JP-A-5-331105). [0004] As reported above, in the prior art, even fats and oils obtained by an optimal selective hydrolysis reaction of fatty acid species using a lipase, even in fats and oils contained in the constituent fatty acids. The DHA content was 53%, and 75% of the glyceride was mainly composed of triglyceride, 24% of diglyceride, and 1% of monoglyceride as a main component. In addition, fats and oils prepared by a lipase synthesis reaction or a transesterification reaction consisted of triglycerides. Generally, triglyceride ingested as food is hydrolyzed to free fatty acids and monoglycerides via diglycerides by the action of lipase, a digestive enzyme secreted from the pancreas, and the decomposed monoglycerides and free fatty acids are converted into bile. It is known to form and absorb micelles with acid salts. However, since fats and oils composed of triglycerides do not have a hydrophilic residue in the molecule, operations such as use of a high-concentration dispersant and ultrasonic treatment were essential to disperse them in an aqueous system. In view of the above,
An object of the present invention is to provide a natural fat / oil having good dispersibility in water and good absorbability. The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems. As a result, the present inventors have found that DHA is contained at a high concentration as a natural fat and oil capable of achieving the object, and a saturated fatty acid content is obtained. The present invention succeeded in obtaining natural fats and oils with a small amount, and completed the present invention. [0006] That is, the present invention relates to anatural fat oroil containing 60% or more of DHA among the constituent fatty acids of the fat and oil, and having a diglyceride ratio of 70% or more in the whole glyceride.
Water-soluble polymer compound
The present invention relatesto natural fats and oilsobtained by performing in the presence of a product . Hereinafter, the present invention will be described in more detail. [0007] The term "natural fat / oil" as used in the present invention means a naturally occurring fatty acid glycerin ester or a fatty acid glycerin ester obtained by enzymatically decomposing a naturally occurring fatty acid glycerin ester. High concentration DH obtained by the present invention
Raw materials for A-containing fats and oils include fish oil rich in DHA,
Marine natural fats and oils such as whale oil and microorganism-derived natural fats and oils can be used. These fats and oils may be selectively hydrolyzed to general fatty acids other than DHA by utilizing the specificity for fatty acid species. However, as enzymes suitable for hydrolysis, substrates having low substrate specificity for DHA are preferred. It is a lipase, especially Candida Sylindrase and Candida
Enzymes derived from Ripolitica are preferred. [0008] Even when an enzyme reaction is carried out with the above enzyme,
According to the conventional method using only water in addition to the substrate fats and oils, it is not possible to obtain natural fats and oils containing DHA at a high concentration of 60% or more and having the composition specified in the present invention. In the present invention, the desired natural fats and oils could be obtained by adding a water-soluble polymer compound to the reaction system when performing the lipase reaction. The water-soluble polymer compound to be added to the lipase reaction system only has to have a property that does not inhibit the lipase reaction, and may be a naturally occurring or synthetic polymer compound. Examples of the naturally occurring water-soluble polymer compound include soluble starch, dextrin, dextran, pectin, gum arabic, natural polymer saccharide compounds such as xanthan gum, gelatin, amino acid polymer compounds such as corn protein-derived peptides, and carboxymethyl cellulose. Cellulose derivatives and the like can be used. Polyvinyl alcohol or the like can be used as the synthetic polymer compound. The concentration of these water-soluble polymer compounds to be added to the lipase reaction system varies depending on the concentration of fats and oils used, but 0.1 to 5% for compounds such as carboxymethylcellulose, katinal, pectin and xanthan gum. It can be used in the range of 0.5 to 2%, and can be used in the range of 1 to 20% for compounds such as gelatin, corn-derived peptide, soluble starch, dextran and gum arabic, and preferably 2 to 5%. is there. [0010] The reaction of hydrolysis with the above enzyme is carried out in the presence of water in an amount sufficient to exhibit the activity of the enzyme.
About 100%. The amount of the enzyme used depends on the concentration of the polyunsaturated fatty acid contained in the substrate, the reaction temperature, and the reaction p.
H, depending on the reaction time, 10 g / g
~ 1000 units (U), preferably 50-3
It is about 00 units (U). The reaction temperature can be appropriately selected within a range in which lipase is not inactivated (20 to 60 ° C), and particularly preferably 25 to 40 ° C. A buffer may be used instead of water in order to keep the pH in the hydrolysis reaction constant. p
H can be reacted in the range of 7 to 9, but is particularly preferably 7.
5 to 8.5. Further, a divalent metal ion such as calcium or magnesium may be added to the reaction solution in order to accelerate the hydrolysis reaction. Its concentration is 10-500m
Although it can be used in the range of M, particularly preferably 150 to 25
Use 0 mM calcium ions. The enzymatic reaction proceeds without any problem even in the presence of air, but polyunsaturated fatty acids are generally easily oxidized, so use an inert gas such as nitrogen or argon gas to perform the reaction in an oxygen-restricted environment. It is preferable to do so. The rate of hydrolysis of fats and oils can be determined by a method such as titration of liberated fatty acids with an alkali or by a method such as gas chromatography. Chromatography is advantageous in terms of measurement accuracy. The hydrolysis was determined by the following equation. (Equation 1) The hydrolysis rate may be controlled so as to be in the range of 60 to 80%, but is preferably 65 to 75%. When the above enzyme is used to carry out the enzymatic reaction, by adding a water-soluble polymer compound to the reaction system, the highly unsaturated fatty acid ester contained in the fat and oil containing the highly unsaturated fatty acid is hardly hydrolyzed. Or, since the degree of hydrolysis is extremely low, fatty acids other than polyunsaturated fatty acids are preferentially hydrolyzed, so if this is removed and undecomposed residual glyceride is separated and collected,
It is possible to obtain oils and fats containing diglycerides and monoglycerides containing polyunsaturated fatty acids at a high concentration, especially DHA at a high concentration. In order to collect a glyceride (natural oil and fat) fraction from the hydrolyzed oil by the above lipase, a commonly used means such as an alkali deacidification method, a steam distillation method, a fractionation using an ion exchange resin, a molecular distillation, an adsorption chromatography, etc. The method may be used. The natural fats and oils of the present invention contain DHA at a high concentration and are mainly composed of diglycerides and monoglycerides, so that they are excellent in digestion and absorption, and the content of saturated fatty acids is extremely low. In addition, it has few problems of excessive energy intake, and has good dispersibility when used in an aqueous system, and easily exhibits useful physiological activity of DHA, and is effectively used for prevention and treatment of adult diseases. EXAMPLES Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited thereto. (Example 1) 0.05 M Tris-HCl buffer (pH 8.
2) Dissolve 12,500 units of lipase derived from Candida lipolytica (manufactured by Amano Pharmaceutical Co., Ltd.) in 100 ml of a reaction solution composed of 0.2 M calcium chloride and 5% gum arabic, and further collect from the tuna head 45 g of mixed fish oil A (fatty acid composition is described in Table 1) 10 g
For 15 hours and continuously p with 2N sodium hydroxide.
The hydrolysis reaction was performed while adjusting H to 8.2, to obtain a decomposed oil. Oils and fats were extracted with 100 ml of hexane, centrifuged (3,000 rpm, 10 minutes), and the hexane layer was recovered. 40 ml of acetone, then 20 m
l of 0.3N sodium hydroxide solution was added, and the mixture was stirred at room temperature for 1 hour. Glyceride from which free fatty acids had been removed could be recovered in the hexane layer, and the weight of the solvent distilled off under reduced pressure was 2.3 g. This product was saponified with an alkali, converted to a methyl ester derivative, and the fatty acid composition was measured by gas chromatography. Table 1 shows the measurement results. The DHA content in the fatty acids was 63.9%.Comparative Example 1 Enzyme reaction, extraction and purification were carried out under the same conditions except that fish oil A shown in Example 1 was replaced with fish oil B (fatty acid composition is described in Table 2) as another raw material. Finally, 3.4 g of glyceride was obtained. The fatty acid composition is shown in Table 2. This product was saponified with an alkali, converted to a methyl ester derivative, and the fatty acid composition was measured by gas chromatography. Table 1 shows the measurement results. The DHA content in the fatty acids is 63.
2%. [Table 1] [Table 2] Example2 1 g of the oil or fat obtained in Example 1 was dissolved in 5 ml of chloroform: acetone (95: 4, v / v), and the solution was applied to a silica gel column filled and suspended in a mixed solvent having the same composition. Elution was carried out with a mixed solvent of the composition. Each glyceride was detected by thin layer chromatography to obtain a fraction containing triglyceride and diglyceride (200 ml). Then, the solvent was distilled off from this fraction under reduced pressure to obtain 0.78 g of oil and fat.With respect to the fats and oils obtained inComparative Example 1 and Example2 , the composition of glyceride was measured using Iatroscan. The results are shown in Table 3. [Table 3] Further, 0.2 g of each of the fats and oils and fish oil B obtained inComparative Example 1 and Example2 were added to 2 ml of purified water, and treated with a homogenizer (0 ° C., 6000 rpm) for 5 minutes. The treated oil and fat dispersion was allowed to stand at 4 ° C. for 20 hours, and its state change was observed. Table 4 shows the results. [Table 4] -: Oil and fat completely separated into two layers +++: completely dispersed and not separated into two layers ++: dispersed state is good, but partially separated slightly.After the oils and fats obtained inComparative Example 1 and Example2 were allowed to stand at 35 ° C. for 2 weeks under the conditions shown in Table 5, the analysis of the oils and fats was performed by using an ear scan. The results are shown in Table 6. The oils and fats obtained in Example2 were stable both in an aqueous solution and in the state of oils and fats, but the oils and fats obtained inComparative Example 1 were slightly decomposed only in a monoglyceride aqueous solution state. [Table 5] * For both A and D, a closed vessel was used and the gas phase was replaced with nitrogen. [Table 6]
