preparation example Construction

[0041] Specifically, the preparation method of the fat composition for infant food (preferably formula milk powder) provided by the present invention is obtained by transesterifying fatty acid or fatty acid ester with freshwater fish oil under the action of lipase. The detailed steps are as follows:

[0042] (1) Mix fatty acid mixture and / or fatty acid ethyl ester mixture with freshwater fish oil to obtain mixture 1;

[0043] (2) contacting mixture 1 with lipase to carry out enzymatic transesterification to obtain mixture 2; and

[0044] (3) Distill and deodorize the mixture 2 to remove fatty acid ethyl ester and fatty acid therein to obtain the oil composition provided by the invention.

[0045] Said freshwater fish oil is preferably catfish oil, more preferably refined catfish oil.

[0046] Catfish oil is mixed with fatty acid mixture and / or fatty acid ethyl ester mixture at a ratio of 1:2 to 1:6 to obtain mixture 1. Fatty acids or fatty acid esters may be derived from ve...

Embodiment 1

[0065] Oil Composition I (Oil Product I)

[0066] Mix 1 part and 2.5 parts of refined catfish oil with vegetable oil fatty acid ethyl ester (wherein soybean oil fatty acid ethyl ester, canola fatty acid ethyl ester and coconut oil fatty acid ethyl ester are 3 parts, 1 part and 1 part respectively) After mixing, they were dehydrated and dried under reduced pressure at 110°C. The dried mixture was then passed through a packed bed containing 100 g Lipozyme RM IM lipase at a flow rate of 150 g / h for enzymatic transesterification, wherein the temperature of the mixture and the lipase were both 55°C. The reacted product removes fatty acid ethyl ester and fatty acid in the product by vacuum distillation and deodorization. Finally, the fatty acid composition and the ratio of palmitic acid at the Sn-2 position to the total palmitic acid were obtained, which was closer to that of breast milk. The results are shown in Table 2.

Embodiment 2

[0068] Oil Composition II (Oil Product II)

[0069] The enzymatic transesterification reaction was as in Example 1. The mixture after transesterification removes fatty acid ethyl ester and fatty acid in the product by molecular distillation. Finally, the fatty acid composition and the ratio of palmitic acid at the Sn-2 position to the total palmitic acid were obtained, which was close to breast milk oil product II. The results are shown in Table 2.

Abstract

The invention discloses oil grease composite for infant food, and a preparation method and applications thereof. The preparation method of the oil grease composite comprises the following steps: firstly, mixing fatty acid mixture, and / or fatty acid ethyl ester mixture, and fish oil so as to obtain a mixture 1; secondly, contacting the mixture 1 with lipase, and then conducting enzymatic interesterification so as to obtain a mixture 2; and thirdly, distilling the mixture 2, removing fatty acid ethyl ester and fatty acid in the mixture 2 so as to obtain the oil grease composite. The invention also discloses applications of the fish oil on preparing the oil grease composite for the infant food.

Description

technical field [0001] The invention relates to the field of food for infants, in particular to a fat composition for food for infants and its preparation method and application. Background technique [0002] Since human beings have been feeding newborns with breast milk, breast milk is superior to any other baby food and is the most natural and most suitable food for babies in the biological world. [0003] The fat content and fatty acid composition of breast milk are compatible with the rapid growth of infants and young children. The fat content and fatty acid composition of breast milk are the gold standard for the fat needs of infants and young children. Breast milk contains about 3-4.5% fat, 98% of which is triglycerides. [0004] Although the fat content in breast milk and infant formula only accounts for 3-4.5% of the total, it provides 50-60% of the energy for growing infants and young children. Absorption plays a key role. The composition and content of fatty aci...
