Problems solved by technology

However, this method involves a vacuum molecular fractionation process, which significantly increases the process cost
Moreover, this method needs to use acetone to fractionate the product to increase the content of OPO, which may introduce harmful solvent acetone into the product, so it is difficult to apply it to industrial scale production

preparation example Construction

[0096] (2) The preparation method of the present invention adopts edible oils and fats of natural origin as raw materials, and because the source of raw materials is widely and easily available, the production cost is lower, and when the human milk fat substitute is prepared according to the method of the present invention, the product can be significantly improved. The profit margins bring good economic benefits to the production enterprises.

[0097] (3) In the preparation method of the present invention, by combining random transesterification, directional transesterification and physical mixing, the desired human milk fat substitute is prepared in a simple and controllable process, which is ultimately beneficial to The desired human milk fat substitute is produced on an industrial scale.

[0098] (4) The preparation method of the present invention realizes the efficient obtaining of the desired oil of the present invention in a simple process by mixing random transesterifi...

Embodiment 1

[0105]The palm oil fraction with IV=8 was placed in the reactor, and vacuum-dried at 105° C. for 30 minutes to remove the moisture in the palm oil fraction. Then, the temperature of the reactor was lowered to 100° C. and kept at this temperature, 0.3 wt % of sodium methoxide was added to the reactor, and the vacuum condition was maintained to carry out random transesterification. After the random transesterification reaction was carried out for 0.1 hour, 25% citric acid aqueous solution (concentration: 8wt%) was added to the reactor to terminate the random transesterification reaction and obtain a reaction product. The reaction product was vibrated and mixed, then centrifuged, washed with water and vacuum dried, and finally refined through decolorization and deodorization operations (at a temperature of 110° C., under a vacuum of 8 mmHg, adding 1.0 wt. % clay, decolorized for 20 minutes; at a temperature of 235°C, under a vacuum of 4mmHg, feed water vapor accounting for 5wt% o...

Embodiment 2

[0109] The palm oil fraction of IV=36 is placed in the reactor, adds the lipase LipozymeTLIM (Novozyme (China) Biotechnology Co., Ltd.) accounting for 8wt% of the palm oil fraction weight in the reactor, Random transesterification was carried out at 40°C for 12h. The lipase is removed by filtration, thereby terminating the random transesterification reaction, thereby obtaining random transesterified oil.

[0110] The random transesterified fat and high oleic sunflower oil were uniformly mixed in a mass ratio of 2:1 at 60° C. to obtain a mixture. Add 4wt% lipase Lipozyme RMIM (Novozymes (China) Biotechnology Co., Ltd.) to the mixture, and perform directional transesterification at 60° C. for 24 hours to obtain directional transesterification oil.

[0111] Take 50 parts by mass of the above-mentioned directional transesterified oil, mix with 15 parts by mass of coconut oil, 21 parts by mass of sunflower oil, 9 parts by mass of soybean oil, and 1 part by mass of linseed oil for ...

Abstract

The invention relates to a human milk fat substitute preparing method, a human milk fat substitute prepared by the method, and uses of the milk fat substitute. In particular, the human milk fat substitute is prepared by adopting edible fat and oil as a raw material, and by random interesterification, directed interesterification and physical mixing. In the human milk fat substitute, based on the total weight of fatty acid residues at the Sn-2 site in triglyceride in the human milk fat substitute, the content of palmitic acid residues at the Sn-2 site is 20-60 wt% and the content of linoleic acid at the Sn-2 site is 3-15 wt%. The total content of linolenic acid is 1-5 wt% based on the total weight of fatty acid residues in triglyceride in the human milk fat substitute. The method adopts the edible fat and oil wide in source as the raw material and is simple in process, and therefore the human milk fat substitute the composition of which is similar to that of human milk triglyceride can be produced in a large scale at a low cost in the industry. The human milk fat substitute prepared by the method can be easily absorbed by infants and is beneficial to growth and development of the infants.

Description

technical field [0001] The present invention relates to a method for preparing a human milk fat substitute, a human milk fat substitute prepared by the method and an application of the milk fat substitute. In particular, the present invention relates to a method for preparing a human milk fat substitute having palmitic acid esterified at the Sn-2 position of a triglyceride at a specific ratio, a human milk fat substitute prepared by the method, and the milk fat substitute produced in the preparation Use in food for infants and young children. Background technique [0002] According to the existing research, it is known that breast milk is the most ideal food in the growth process of infants and young children, and it can provide comprehensive and sufficient nutrition for the growth of infants and young children. Therefore, breast milk is also regarded as the gold standard for promoting the healthy growth of infants (NamSooHan et al., Biotechnological production of human mil...
