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

[0090] (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.

[0091] (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.

[0092] (4) The preparation method of the present invention realizes the efficient production of the desired human milk fat substitute of the present invention in a simple process by mixi...

Embodiment 1

[0099] The palm oil fraction with IV=25 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 245°C, under a vacuum of 4mmHg, feed water vapor accounting for 5wt%...

Embodiment 2

[0103]The palm oil fraction of IV=8 is placed in the reactor, adds the lipase LipozymeTLIM (Novozyme (China) Biotechnology Co., Ltd.) that accounts for 8wt% of described palm oil fraction weight in the reactor, Random transesterification was carried out at 65°C for 8h. The lipase is removed by filtration, thereby terminating the random transesterification reaction to obtain a random transesterification product. The random transesterification reaction product was processed through the refining operation described in Example 1 to obtain random transesterification oil.

[0104] Take 20 parts by mass of the random transesterified oil, 40 parts by mass of olive oil, 29 parts by mass of soybean oil, 10 parts by mass of palm kernel oil and 1 part by mass of perilla oil and mix them uniformly at 80°C to obtain the formulated grease.

[0105] Add 0.5wt% lipase LipozymeRMIM (Novozymes (China) Biotechnology Co., Ltd.) to the prepared oil, and carry out directional transesterification a...

Abstract

The invention relates to a preparation method of a human milk fat substitute, the human milk fat substitute prepared by the method, and use of the milk fat substitute. Specifically, edible fat is used as a raw material, and a random ester exchange reaction, a physical mixed reaction and a directed ester exchange reaction are performed, so that the human milk fat substitute is prepared. In the human milk fat substitute disclosed by the invention, compared with the total weight of fatty acid residues at an Sn-2 site of triglyceride of the human milk fat substitute, the content of palmitic acid residues at the Sn-2 site is 20wt%-60wt%, and the content of linoleic acid at the Sn-2 site is 3wt%-15wt%; compared with the total weight of the fatty acid residues in the triglyceride of the human milk fat substitute, the total content of the linolenic acid is 1wt%-5wt%. According to the method disclosed by the invention, the edible fat with broad sources is used as the raw material, and the technology is simple, so that the mass production of the human milk fat substitute of which the structure is similar to that of breast milk triglyceride in industry at a low cost can be realized. The human milk fat substitute prepared by the method disclosed by the invention is easy to absorb by babies, and promotion of the growth and the development of the babies is facilitated.

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 in a specific ratio, a human milk fat substitute prepared by the method, and the milk fat substitute in the preparation of 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 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 milk oligosa...
