Title:
PREPARATION METHOD FOR STRUCTURED LIPID RICH IN 1,3-DIOLEATE-2-PALMITIC ACID TRIGLYCERIDE
Document Type and Number:
WIPO Patent Application WO/2016/176987
Kind Code:
A1
Abstract:
Provided is a method for preparing a structured lipid rich in 1,3-dioleate-2-palmitic acid triglyceride, related to the technical filed of lipids. Catfish oil is melted at 50-60 °C for 30-60 mins, and cooled at a cooling rate of 1-5 °C/min to 15-30 °C; the catfish oil is kept at this temperature for 5-48 h, then liquid-state oil is removed by means of filtration to produce a catfish oil solid fat constituent rich in palmitic acid at sn-2 position; the catfish oil solid fat constituent undergoes acid hydrolysis with sn-1,3 position specific lipase serving as a catalyst and with free fatty acids sourced from a high oleic vegetable oil serving as an acyl donor, the free fatty acids are removed to produce a product rich in 1,3-dioleate-2-palmitic acid triglyceride. The raw material is inexpensive. The product produced has a high 1,3-dioleate-2-palmitic acid triglyceride content and is broadly applicable as an additive in powdered infant formula milk fat.
