Embodiment 1

[0040] This embodiment provides a kind of production method of 1,3-dioleic acid-2-palmitic acid triglyceride, and its production method comprises the following steps:

[0041] a) Using palm hard oil as the main raw material, mix palmitic acid and Sn-1,3-specific lipase in a mass ratio of 1:3:0.06 and put it into a stainless steel reaction kettle, start stirring, raise the temperature to 65°C, and keep it warm for 120 minutes ;

[0042] b) Filter the reaction solution to recover Sn-1,3-specific lipase; cool the reaction solution at a rate of 3°C / min, and when the temperature drops to 30-35°C, keep it warm for 60 minutes to carry out cooling and crystallization, degreasing and exchanging Impurities such as oleic acid, linoleic acid and myristic acid replaced in the reaction obtain a mixture A of triglycerides and palmitic acid with high palmitic acid content;

[0043] c) Put mixture A: free invertase in a stainless steel reaction kettle at a mass ratio of 1:0.06, start stirring...

Abstract

The invention provides a production method of 1,3-olein-2-palmitin, which is low in production cost, environment-friendly and high in product content. According to the method, Sn-1,3 specific lipase is used as a catalyst, so that palm oil and palmitic acid are subjected to transesterification, and the content of palmitic acid in the grease is increased. Then, the palmitic acid is rearranged at theposition of triglyceride through free invertase, and the content of the triglyceride with the Sn-2 as the palmitic acid is increased. Besides, by alternately using the Sn-1,3 specific lipase and freeconverting enzyme, the content of the triglyceride with the Sn-2 as the palmitic acid can be continuously increased. The method comprises the following steps: mixing the triglyceride rich in Sn-2 position palmitic acid with oleic acid, and replacing the palmitic acid at Sn-1 and Sn-3 position with oleic acid by using the Sn-1,3 specific lipase as the catalyst to obtain high-content 1,3-olein-2-palmitin (OPO).

Description

technical field [0001] The invention belongs to the technical field of triglyceride synthesis, and in particular relates to a production method of 1,3-dioleic acid-2-palmitic acid triglyceride. Background technique [0002] Breast milk is considered the only green food for babies to grow up. Breast milk contains various physiologically active substances and about 3%-4% fat, 98% of which are triglycerides. They can not only provide various nutrients needed by babies, but also provide non-essential unsaturated fatty acids needed by babies ( That is, unsaturated fatty acids that cannot be synthesized in the baby's body and need to be supplemented by the outside world), provide most of the energy for the growth and development of infants and young children. Studies have found that the structure of triglycerides in breast milk is highly specific, which is conducive to the efficient absorption of breast milk fat by infants and young children. About 60%-70% of palmitate in breast...
