Embodiment 1

[0025] A total of 200 g of commercially available CLA and glyceryl caprylate (CLA: glyceryl caprate=3, mol) was put into a 500 ml Erlenmeyer flask with a stopper, preheated to 50° C., and then immobilized lipase (Novo 435, Novozymes A / S) 40g, placed in a constant temperature water-bath shaker at 50°C, oscillating for 5 hours under the condition of 200r / min, stop the reaction, filter the product to remove the immobilized enzyme particles, and then further separate the product by molecular distillation Fatty acid, heavy fraction was then subjected to decolorization and deodorization in a conventional manner to obtain oil composition 1.

[0026] Under the conditions of 50% water addition and strong stirring, the commercially available rapeseed oil is used as a catalyst (Lipase F-AP15, Amano Enzyme Inc. product, or other companies' high hydrolysis lipase) with free 1,3-position specific lipase Free lipase product with enzymatic activity) hydrolyzes oil at 40°C, stops the reaction ...

Embodiment 2

[0029]A total of 500 g of commercially available CLA ethyl ester and caprylic capric acid glyceride (CLA ethyl ester: caprylic capric glyceride = 3, mol) was put into a stirred 60°C constant temperature reactor and mixed evenly, and the immobilized lipase (Lipozyme TL IM, Novozymes A / S) 10g is packed into a packed bed column type enzyme reactor (with insulation jacket), then adopt metering pump to constantly extract reaction substrate from reaction vessel and inject into enzyme reactor, make it in immobilized enzyme The transesterification reaction occurs under the catalysis of the enzyme reactor, and the reaction product flows out of the enzyme reactor and directly enters the container containing the substrate, in this way a continuous cycle reaction is carried out. Adjust the flow rate to be about 3L / hr to keep the grease circulating in the enzyme reactor for 6 hours and then stop the reaction. The reaction product was subjected to molecular distillation to further separate ...

Embodiment 3

[0033] The oil composition 1 and the oil composition 2 were uniformly mixed at a volume ratio of 15:85 to obtain the oil composition 8.

Abstract

The invention discloses a functional grease composition, which is characterized in that the invention consists of glyceride containing conjugated linoleic acid and medium chain fatty acid and glyceride rich in diglyceride. The grease composition has the function of preventing and curing metabolic syndrome, use adaptability which is nearly equivalent to the common edible oil, good taste, high safety and relatively low production cost, thus being beneficial to industrialized production and market promotion.

Description

technical field [0001] The invention relates to an oil composition and its application. The oil composition can prevent and treat metabolic syndrome and is applied to edible oil, fat or oil processed food and pharmaceutical composition. 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 deve...
