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.
