Infant milk powder oil preparation method based on triglyceride analysis to simulate breast milk fat

Abstract

The invention discloses a preparation method of baby milk grease for simulating breast milk fat based on triglyceride analysis. The method comprises the following steps: I, determining types and corresponding contents of triglyceride and fatty acids in N breast milk samples, wherein the effective components m of the N breast milk samples comprise triglyceride A, necessary fatty acids B, triglyceride C and digestive absorption triglyceride D, the content range of the effective components m is R(m)min-R(m)max, and the average content is X(m); II, determining the content of various effective components m in n to-be-added plant grease and calculating the various effective component content H(m) in mixed grease of the n to-be-added plant grease in different adding proportions; and III, calculating the comprehensive score of the different mixed grease based on 100 scores of effective components of breast milk, wherein the compositions of the mixed grease, the comprehensive score of which iscloser to 100, is closer to those of the breast milk fat. The body milk grease prepared by the method disclosed by the invention can achieve breast milk of fat.

Description

technical field [0001] The invention relates to the technical field of infant formula milk powder. More specifically, the present invention relates to a method for preparing infant formula milk powder fat based on triglyceride analysis to simulate breast milk fat structure. Background technique [0002] With the opening of the "two-child policy" on January 1, 2016, the number of newborns in my country this year will reach 20 to 25 million, and because many mothers choose artificial feeding due to personal, cultural, social or economic reasons, this makes the worldwide Only 35% of babies in the world are breastfed.

Problems solved by technology

At present, there are two main ways to add fat in infant formula milk powder produced in China, one is to simulate breast milk fat by adding OPO, and the other is to submit the final mixed oil to a third party; however, the important glycerin in breast milk fat The three-ester structure is not only OPO. The first method makes the structure of the oil in infant formula milk powder single, and fails to achieve "breast milkization". The disadvantage of the second method is that the third party only provides the mixture provided by it. Whether the fatty acid inspection index of the oil meets the national standard, and will not inform the corresponding company of the blending ratio of its blended oil. In fact, it is unknown whether the blended oil is similar to breast milk. The manufacturer is in a passive position, and it also causes the price of infant milk powder to be high. situation
