Problems solved by technology

However, 1,3-unsaturated sn-2-saturated fatty acid triglycerides are only one type of triglycerides in breast milk fat, and when formula milk powder is added, it is usually necessary to add 5-30% other oils to it to adjust the fatty acid composition , so it is difficult to ensure that the sn-2 saturated fatty acid composition is within the range of breast milk fat

Embodiment 1

[0053] Palm stearin with a palmitic acid content of 91.2% and a sn-2 palmitic acid content of 85.4% was selected as the starting material. According to analysis, compared with breast milk fat, the palm stearin sn-2 saturated fatty acid lacks medium carbon chain fatty acid and myristic acid (C14:0).

Abstract

The invention discloses a product rich in 1, 3-unsaturate-2-saturated fatty acid structural fat and a preparation method thereof, the product is based on 5-30% of sn-2-site saturated fatty acid composition higher than breast milk fat, palm stearin is used as a raw material, and sn-2-site saturated fatty acid composition is calculated and adjusted through a grease mixing model; and the proportion of fatty acid required by acidolysis of the mixed grease is predicted by using an enzyme catalysis acidolysis reaction fatty acid balance model, a product rich in 1, 3-unsaturated 2-saturated fatty acid structure grease is obtained by using a two-step acidolysis reaction coupling low-temperature program fractionation method, and when 5-30% of grease is exogenously added to the obtained product, the sn-2 saturated fatty acid composition is still in the breast milk fat range.

Description

technical field [0001] The invention belongs to the technical field of oil technology, and in particular relates to a product rich in 1,3-unsaturated-2-saturated fatty acid structural lipid and a preparation method thereof. Background technique [0002] Fat in breast milk accounts for 3-5% of the total milk and provides more than 50% of the energy for the baby. The triglyceride content in breast milk lipids is above 98%. Triglycerides contain a variety of fatty acids, including medium-chain fatty acids, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, odd-numbered carbon-chain fatty acids, and branched-chain fatty acids. Among these fatty acids, fatty acids with a content greater than 1% are oleic acid, palmitic acid, linoleic acid, stearic acid, myristic acid, lauric acid and palmitoleic acid. [0003] The fatty acid distribution of triglycerides in breast milk lipids is unique. Most of the saturated fatty acids are distributed in the sn-2 ...
