Problems solved by technology

Due to the solubility problem, it is difficult to add a high content of sterols to oils. Since there is no large-scale production and supply of sterols, it is also difficult to produce such oils in large quantities.

Embodiment 1

[0022] Put a total of 200 g of commercially available CLA and caprylic acid glyceride (CLA: caprylic acid glyceride = 3, mol) into a 500ml flask with stopper, preheat it to 50°C and add immobilized lipase (Novo435, NovozymesA) / S) 40g, placed in a constant temperature water bath shaker at 50℃, oscillated at 200r / min for 5h, and then stopped the reaction. After the product was filtered to remove the immobilized enzyme particles, the fatty acid in the product was further separated by molecular distillation. The heavy fraction was then decolorized and deodorized in a conventional manner to obtain an oil and fat composition 1.

[0023] Under the conditions of 50% water addition and vigorous stirring, use the free 1,3-position specific lipase as a catalyst for the commercially available rapeseed oil (LipAse F-AP15, product of AmAno Enzyme Inc., or high hydrolysis from other companies). Enzyme-active free lipase product) at 40°C for the hydrolysis reaction of oil and fat, and stop the ...

Embodiment 2

[0026] Put a total of 500 g of commercially available CLA ethyl ester and caprylic acid glyceride (CLA ethyl ester: caprylic acid glyceride = 3, mol) into a stirred 60°C constant temperature reactor and mix uniformly. The immobilized lipase (Lipozyme TL IM, Novozymes A / S) 10g is packed into a packed bed column type enzyme reactor (with insulation jacket), and then a metering pump is used to continuously extract the reaction substrate from the reaction vessel and inject it into the enzyme reactor to immobilize the enzyme The transesterification reaction occurs under the catalysis of, and the reaction product flows out of the enzyme reactor and directly enters the container with the substrate, in this way the continuous cycle reaction is carried out. Adjust the flow rate to about 3L / hr to keep the oil in the enzyme reactor for 6 hours and then stop the reaction. The reaction product undergoes molecular distillation to further separate the ethyl ester, and the heavy fraction is th...

Embodiment 3

[0030] The oil and fat composition 1 and the oil and fat composition 2 were uniformly mixed in a volume ratio of 15:85 to obtain a fat and oil composition 8.

Abstract

The invention relates to the field of grease, and discloses an improved grease composition. The improved grease composition comprises the following ingredients by weight percent: 0.5-30% of an ingredient A, 68.5-99.4% of an ingredient B, less than or equal to 2% of an ingredient C, and less than or equal to 2% of an ingredient D, wherein the ingredient A is glycerides containing conjugated linoleic acids, and specifically comprises 20-70% of conjugated linoleic acids and 10-60% of medium-chain fatty acids; the ingredient B is glycerides without conjugated linoleic acids, and specifically comprises 40-90.7% of diglyceride, 9-59.5% of triglyceride and 0.1-5% of monoglyceride; the ingredient C is free fatty acids; and the ingredient D is stearic acid.

Description

Technical field [0001] The present invention relates to the field of fats and oils, in particular to an improved fat composition. Background technique [0002] Oils and fats are daily necessities for people. They provide rich nutrition and essential energy while giving dishes a good flavor and taste. At the same time, fats and oils are also important raw materials in food processing. In modern society, the intake of fats and oils is increasing day by day. At present, the average daily consumption of fats and oils per capita in my country is nearly 50 grams, which is twice the average daily consumption of fats and oils recommended by the World Health Organization. Excessive oil intake and unbalanced nutrition have caused the prevalence of obesity, hyperlipidemia, cardiovascular disease, fatty liver and other wealthy diseases to increase year by year, and the more likely it is that a variety of diseases will occur and develop into metabolic syndrome patients. The higher the coming...
