Description
Technical field
The invention belongs to Vegetable oil lipoprotein and extract processing technique field, relate generally to the preparation method of the balanced mixed oil of a kind of Fatty acids composition.
Background technology
At present, fitness-for-all consciousness significantly improves, and the absorption of grease is the requisite integral part of daily life.In recent years, because the diseases such as hyperlipidemia, arteriosclerosis, coronary heart disease increase day by day, cause people's concern.And cause that these diseases and the unbalanced grease of people's edible fatty acid have important relationship, the grease of the above saturated fatty acid of excess ingestion 12 carbon (not comprising stearic acid) not only causes body's cholesterol to raise, and causes arteriosclerosis and the coronary heart disease of serious harm HUMAN HEALTH simultaneously; By appropriate picked-up, be rich in n-6 series (linolic acid, γ-linolenic acid, arachidonic acid) and n-3 series (alpha-linolenic acid, EPA, DHA) polyunsaturated fatty acid grease, there is the function that reduces cholesterol level and low-density lipoprotein (LDL) level.Therefore, the diverse lipid acid of the absorption of scientific and reasonable equilibrium, to maintaining the good function of tissue, ensures that lasting health is very necessary.For this reason, the ratio that WHO and Chinese Soclety of Nutrition propose lipid acid is with reference to dietary standard: SFA: MUFA: PUFA=0.27:1:1; Omega 6: Omega 3=1-5:1.
After traditional mixed oil production method proposes single grease, then be in harmonious proportion in proportion, this method not only efficiency is low, cost is high, and the pretreated method of clearly not high oil crops, thus higher oil extracting rate can not be obtained, cause in process of production a large amount of significant loss.
The principle of design of the present invention is that to the absorption ratio of the meals total fatty acids of Chinese residents the fatty acid ratio of edible oil is designed to meet Chinese Soclety of Nutrition: saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid=(0-1): 1: 1, n-6 polyunsaturated fatty acid: n-3 polyunsaturated fatty acid=(1-5): 1.Three kinds of fatty acid ratios approach 0.27: 1: 1 as far as possible, and guarantee that Omega 6: Omega 3 ratios approach 1-5: 1.Unbalanced for solving the lipid acid of single natural fats and oils, and high oil crops lack the problem of pretreatment process, it is raw material that soybean, vegetable seed, purple perilla, fiery pockmarks, seed of Radix Oenotherae erythrosepalae are take in the present invention, after being first mixed in proportion, mixing oil plant carries out supersound process and in conjunction with biological enzyme, produces Fatty acids composition equilibrium (SFA: MUFA: PUFA=0.27:1:1, Omega 6: Omega 3=1-5:1) mixed oil.
After being mixed in proportion five kinds of raw materials, the present invention's original creation utilize the ultrasonic enzyme that involves to combine dual pretreatment mode destruction raw material cell wall, when improving grease release rate, reduce the loss of biologically active substance, obtained the mixed oil of high nutritional activities and fatty acid balance simultaneously.The present invention makes mixed oil fatty acid ratio and approaches (SFA: MUFA: PUFA=0.27:1:1, Omega 6: Omega 3=1-5:1), can meet physiology and the nutritional needs of different crowd, and only need a production line directly to produce, cheap, balanced in nutrition, coordinative fatty acid ratio.
Summary of the invention
