Problems solved by technology

However, the fat components in formula milk powder currently on the market are only simulated by simple physical mixing of breast milk lipids
Moreover, most of the reference standards are breast milk lipids from European and American countries. Due to the influence of race, region and eating habits, there is a large gap between the lipid components of breast milk lipids in European and American countries and that in my country. Some infant formula milk powder is not suitable for infants and young children in our country

Embodiment 1

[0044] The stearic fatty acid composition and distribution of pangasius oil used in this embodiment are detailed in Table 1, and the fatty acid composition of camphor tree seed kernel oil, linseed oil, algae oil and microbial oil are detailed in Table 2. According to the mass ratio of the medium carbon chain fatty acid to the total fatty acid mass ratio is 10%, the mass ratio of linolenic acid to linoleic acid is 2, the mass ratio of ARA to DHA is 1, and the mass ratio of ARA and DHA to the total fatty acid mass ratio is 0.5 , 0.6, 0.7, 0.8, 0.9, and 1.0 fatty acid design amounts Weighed six groups of pangasius fish oil stearin, camphor tree seed oil, linseed oil, algae oil, and microbial oil, and added them to six esterification In the reactor, lipase Lipozyme RM was added according to 10% (w / w) of the mass of the mixed oil. The reaction temperature was 60°C, and the stirring time was 8h. After the transesterification reaction, the lipase in the reaction solution was separat...

Embodiment 2

[0054] The mass ratio of medium-carbon chain fatty acids to total fatty acids is 10%, the mass ratio of linolenic acid to linoleic acid is 2, the mass ratio of ARA to DHA is 1, and the mass ratio of ARA and DHA to total fatty acids is 1 %, take by weighing 148.775g pangasius oil stearin, 25.25g camphor tree seed kernel oil, 75g linseed oil, 7.25g algae oil and 6.275g microbial oil total three groups, add respectively to three same specification esterification reactions Add lipase Lipozyme RM IM, lipase Lipozyme TL IM and lipase Lipozyme RM respectively according to 10% (w / w) of the mixed oil mass. The transesterification reaction conditions are: magnetic stirring (stirrer bar 30 mm×10 mm, rotation speed 100 rpm), reaction temperature 60° C., and reaction time 8 h.

[0055] After the reaction, the transesterification rate was measured by HPLC-ELSD detection method. To compare and analyze the effect of lipase types on transesterification rate, select lipase types. As can be se...

Embodiment 3

[0059] In this example, according to the mass ratio of medium-carbon chain fatty acids to total fatty acids as 10%, the mass ratio of linolenic acid to linoleic acid is 2, the mass ratio of ARA to DHA is 1, and the mass ratio of ARA and DHA respectively accounts for The total fatty acid mass ratio is 1%. Weigh 148.775g of pangasius oil stearin, 25.25g of camphor seed kernel oil, 75g of linseed oil, 7.25g of algae oil and 6.275g of microbial oil, and add them to six groups respectively. In the esterification reactor of the same specification. The transesterification reaction conditions are: lipase Lipozyme RM is 2%-12% (percentage of mixed oil mass), magnetic stirring (stirrer bar 30mm×10mm, rotation speed 100rpm), reaction temperature is 60°C, and reaction time is 8h.

[0060] After the reaction, the transesterification rate was measured by HPLC-ELSD detection method. Comparative analysis of the effect of the amount of enzyme added on the rate of transesterification, to deter...

Abstract

The invention relates to a breast milk lipid substitute and a preparation method and application thereof, and the breast milk lipid substitute is formed by carrying out five-membered ester exchange on bala fish oil stearin, camphor tree seed kernel oil, linolenic acid grease, ARA grease and DHA grease. According to the invention, an excellent breast milk lipid substitute is constructed through transesterification. The prepared breast milk lipid substitute has the characteristics that the triglyceride structure and the fatty acid composition are similar to those of breast milk, the content of palmitic acid at the site 2 is greater than or equal to 30%, energy can be quickly supplied, essential fatty acids in a body can be balanced, ARA and DHA can be supplemented, and the like, and the breast milk lipid substitute can be widely applied to infant foods.

Description

technical field [0001] The invention belongs to the technical field of edible fats and oils. Background technique [0002] Infants and young children are a group in a special growth stage. At this stage, they need to consume a large amount of comprehensive nutrition. The quantity and quality of nutrition intake during this period directly affect the future growth and development of infants and young children. Breast milk is the most direct source of energy and nutrients for infants and young children, and contains a large number of special ingredients that can promote the healthy growth and development of infants. [0003] Breast milk lipids are the main nutrients of breast milk, accounting for 3% to 5% of breast milk. 98% of breast milk lipids are triglycerides, which are the main energy source for the growth and development of infants. When infants are 0-6 months old, breast milk lipids provide 40% to 50% of the energy needed by infants and young children, and at the same...
