example 1

[0036] Compared with human milk fat, lard lacks lauric acid, myristic acid, linoleic acid and linolenic acid; In terms of triglyceride composition, compared with human milk fat, lard lacks some triglycerides containing medium-chain fatty acids, and at the same time, the content of triglycerides such as PPO and POS is too high. The saturated triglycerides in lard can be removed by fractionation, and other oils can be added at the same time to improve the chemical composition of lard. According to the chemical composition of various vegetable oils, choose palm kernel oil rich in medium-chain fatty acids, rapeseed oil rich in oleic acid, and sunflower oil rich in linoleic acid for blending.

[0037] The raw material lard is melted at 60°C and maintained for 30 minutes, and then dropped to 21°C at a cooling rate of 2°C / h. Under this condition, the crystal growth time is 9 hours, and the stirring rate is 35 rpm; Lipid separation. The partial fatty acid composition and distributio...

Abstract

The invention discloses a human milk substitute fat composition which is prepared from natural grease or modified grease as a raw material. On the basis of composition and distribution of fatty acids of human milk fat and the composition of triglyceride, the fat composition is prepared by mixing the grease and is similar with the human milk fat in the aspects of the composition and distribution of fatty acids of human milk fat and the composition of triglyceride. The similarity of the substitute fat composition with human milk fat in the aspects of the composition and distribution of fatty acids of human milk fat and the composition of triglyceride is evaluated through a human milk substitute fat model, which proves that the similarity of fatty acids is higher than 90%, the similarity of sn-2 fatty acid is higher than 80% and the similarity of triglyceride is higher than 60%. The total similarity of the substitute fat composition with the human milk fat is more than 70%.

Description

technical field [0001] The invention relates to the field of food for infants and young children, in particular to a human milk replacement fat composition based on triglycerides. Background technique [0002] Human milk contains 3-5% fat, which is the main energy source (>50%) for newborns, of which triglycerides account for more than 98%. Human milk fat contains about 200 kinds of fatty acids, including medium-chain fatty acids, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, odd-numbered carbon chain fatty acids, branched-chain fatty acids, trans fatty acids, and hydroxy fatty acids. Among these fatty acids, fatty acids with a content greater than 1% include oleic acid (25-35%), palmitic acid (20-30%), linoleic acid (10-20%), stearic acid (5-9%), Myristic acid (4-9%), lauric acid (3-7%) and palmitoleic acid (1-3%). The fatty acid distribution of triglycerides in human milk fat is unique. More than 60% of palmitic acid is distributed i...
