Embodiment 1

[0024]Under the condition of 50% water addition (by oil weight), the pomegranate seed oil is catalyzed with free 1,3-position specific lipase (Lipase F-AP15, Amano Enzyme Inc., enzyme amount is 0.1% of the weight of the oil) at 40°C for the hydrolysis reaction of the oil, stop the reaction after the acid value of the oil sample reaches 60mg KOH / g, keep it at 65°C for 0.5h to inactivate the enzyme, then let it stand to remove most of the water, in the condition of vacuum and 80°C The remaining water was removed under the pressure, and then diatomite with an oil weight of 1% was added, and the residual enzyme protein was removed by filtration after stirring for 0.5h. Composition 1 based on esters and triglycerides and Composition 2 based on free fatty acids.

[0025] After mixing Composition 2 and glycerin (fatty acid group: glycerol=2, mol), add immobilized 1,3-specific lipase (Lipozyme RM IM, Novozymes A / S, the amount of enzyme added is oil weight 5%), while keeping the insid...

Embodiment 2

[0027] Under the condition of 30% water addition (in terms of oil weight) and strong stirring, the safflower oil is used as a catalyst (Lipozyme 20000L, Novozymes A / S, the amount of enzyme added is oil weight of 0.2%) at 45°C for the hydrolysis reaction of oil, stop the reaction after the acid value of the oil sample reaches 65mg KOH / g, keep it at 70°C for 0.5h to inactivate the enzyme activity, then let it stand to remove most of the water, under the conditions of vacuum and 80°C Remove the remaining water, then add diatomaceous earth with an oil weight of 1.5%, stir for 0.5h, filter to remove the residual enzyme protein, and then further separate the remaining product through molecular distillation, then decolorize and deodorize in a conventional manner to obtain diglyceride and triglyceride-based oil composition 4 and free fatty acid-based composition 5.

[0028] After mixing Composition 5 and glycerol (fatty acid group: glycerol=2, mol), add immobilized 1,3-specific lipase...

Embodiment 3

[0030] Cannabis oil and glycerin (cannabis oil: glycerol=2, mol) are placed in 50mL Erlenmeyer flask with stopper, after thorough mixing, add the immobilized lipase (Lipozyme RM IM of oil weight 5%, Novozymes A / S), Shake the reaction at a reaction temperature of 60°C for 8 hours. After the reaction product is filtered to remove immobilized enzyme particles, glycerin, ethyl ester and monoglyceride are further separated by molecular distillation, and the heavy fraction is then decolorized and deodorized in a conventional manner. Fat composition 7 was obtained.

Abstract

The invention discloses an oil and fat composition containing diglyceride and use thereof. The oil and fat composition contains 35 to 90% of diglyceride by mass, 9 to 64% of triglyceride by mass, 0.1 to 5% of monoglyceride by mass and 2% of free fatty acid by mass, wherein the fatty acid of the oil and fat composition contains 1 to 45% conjugated trienes unsaturated fatty acid by mass and not more than 10% of saturated fatty acid by mass, and the mass ratio of Omega-6 unsaturated fatty acid to Omega-3 unsaturated fatty acid is 1 to 6:1. The oil and fat composition has the function of preventing and relieving metabolic syndrome, the applicability almost equivalent to common edible oils, good taste, high safety and low production cost, and is favorable for industrial production and marketing.

Description

technical field [0001] The invention relates to the field of fats and oils, more specifically to a diglyceride-containing fats and oils composition and its application. Background technique [0002] Fat is a daily necessity for people. It provides rich nutrition and essential energy while imparting good flavor and taste to dishes. At the same time, fat is also an important raw material in food processing. In modern society, the intake of oil is increasing day by day. At present, the average daily oil consumption of urban residents in my country is nearly 50 grams, which is twice the average daily oil consumption recommended by the World Health Organization. Excessive fat intake and unbalanced nutrition have caused the prevalence of obesity, hyperlipidemia, cardiovascular disease, fatty liver and other affluent diseases to increase year by year, and the probability of a variety of diseases clustering and developing into metabolic syndrome patients is getting higher and higher...
