Embodiment 1

[0054] Example 1 Human Milk Fat Analogue

[0055] A human milk fat analogue is to heat lard at 60°C for 20 minutes, and then reduce the temperature of the oil sample to 33°C at a cooling rate of 4°C / h; this process is stirred at 46rpm / min to destroy the original crystal form Afterwards, 33L-lard was obtained.

Embodiment 2

[0056] Example 2 Human Milk Fat Analogues

[0057] A human milk fat analogue consisting of 33L-lard, camellia oleifera seed oil, soybean oil and coconut oil. 33L-Lard is obtained by keeping lard at 60°C for 20 minutes, and then reducing the temperature of the oil sample to 33°C at a cooling rate of 4°C / h; stirring at 46rpm / min in this process to destroy the original crystal form. 33L - lard.

[0058] Human milk fat analogues were formulated with 19.78% camellia oil, 15.14% soybean oil, 10.28% coconut oil and 54.8% 33L-lard oil in proportion to obtain human milk fat analogues.

Abstract

The invention relates to the technical field of infant foods, and discloses a human milk fat analog and a preparation method thereof, as well as infant formula milk fluid and a preparation method thereof. The human milk fat analog comprises a part which is liquid at 33 DEG C and is obtained through performing fractionation on lard by a dry method. The infant formula milk fluid consists of the following substances in percentage by mass, based on the total mass of the milk fluid: 0.05%-0.5% of phosphatide, 1.05%-1.86% of whey protein, 0.7%-1.24% of casein, 1.75%-3.55% of the human milk fat analog and the balance of water. The milk fluid prepared by an ultrasonic-assisted high-speed homogenizing and emulsifying method has the characteristics of being small in particle diameter, narrow in distribution, high in stability and the like. The human milk fat analog is innovatively used as a fat core material. The human milk fat analog is close to human milk fat on the composition of fatty acid,and the human milk fat can be better simulated from the structure of the fatty acid.

Description

technical field [0001] The invention relates to the technical field of food for infants and young children, and more specifically, relates to a human milk fat analogue, formula emulsion for infants and young children and a preparation method thereof. Background technique [0002] Although the fat ingredients (vegetable oil and milk fat) in traditional infant formula emulsions are similar to human milk fat in terms of fatty acid composition, there is still a large difference in glyceride structure. loss. In the past ten years, animal and vegetable oils have been enzymatically catalyzed to obtain human milk fat analogues (or human milk fat substitutes) rich in 1,3-Dioleoyl-2-palmitoylglycerol (OPO). products) is one of the hotspots in the research of infant formula milk. Compared with oil ingredients in traditional infant formula emulsions, human milk fat analogues are rich in OPO, which makes fatty acids easy to absorb, reduces insoluble calcium soaps and improves intestina...
