Problems solved by technology

For example, lard and mixed fatty acids rich in palmitic acid at the Sn-2 position were used as substrates, and LipozymeRMIM enzyme was used as a catalyst to enzymatically prepare a substitute for fatty acid composition and triglyceride structure similar to breast milk fat (China Oil, 2009 ,34(2):39-42), but the lard contains too much stearic acid, which can easily cause the product to agglomerate and affect the absorption of infants
Moreover, the linoleic acid and linolenic acid in lard are too low, and after artificial addition, it is easy to produce secondary pollution

Abstract

The invention discloses a method for preparing a synthetic breast milk fat substitute by using silkworm chrysalis oil. The high-quality silkworm chrysalis oil is obtained by supercritical CO2 extraction and gradient freezing crystallization, and the high-quality silkworm chrysalis oil is mixed with oleic acid, and lipase enzymolysis is utilized to obtain the breast milk fat substitute. The substitute has the following beneficial effects: the structure of triglycerides in the obtained breast milk fat substitute is very close to breast milk fat, for instance, the content of Sn-2 palmitate can reach 60% or above which is very similar to that of breast milk, and the content of Sn-2 oleic acid is similar to that of the breast milk fat. The alpha-linolenic acid content is extremely high up to 82% or above, and the alpha-linolenic acid has obvious effects on enhancing intelligence and memory and protecting eyesight, has the effect of continuously reducing blood lipid and cholesterol and resisting platelet aggregation, has the functions of lowering blood pressure, preventing and treating thrombus formation and preventing cardiovascular diseases, and has great help to improve the growth anddevelopment of infants and to improve the immunity.

Description

technical field [0001] The invention relates to the technical field of infant food processing, in particular to a method for preparing a synthetic breast milk fat substitute by using silkworm chrysalis oil. Background technique [0002] Breast milk is the perfect food for a baby's growth and development. WHO recommends breastfeeding babies for at least 6 months after birth to ensure their growth and development and improve their immunity. Breast milk contains about 4-4.5% fat, 98% of which are triglycerides. The types of fatty acids (FA) in breast milk are complex. Saturated fatty acids include medium-chain, medium-long-chain and long-chain saturated fatty acids, such as lauric acid (5-7%), palmitic acid (20-24%), stearic acid (7.1- 9%); monounsaturated fatty acids include oleic acid (31~38%), palmitoleic acid (2.5~3.8%); n~3 polyunsaturated fatty acids contain linoleic acid, α-linolenic acid and docosahexa Dienoic acid (DHA, 0.3-1.9%), etc. However, modern women cannot ...
