[0071] Grease composition and its preparation method

[0072] The present invention provides a method for preparing an oil composition, comprising (1) random transesterification of oil containing palmitic acid and oil containing lauric acid and / or myristic acid to obtain transesterified oil, (2) combining the above steps (1 ) The obtained transesterified oil is reacted with a mixture of fatty acids containing unsaturated fatty acids or their esters in the presence of lipase.

[0073] In the present invention, the palmitic acid-containing fat contains 40% by weight or more of palmitic acid, preferably 40% by weight or more of palmitic acid, more preferably 45 to 80% by weight of palmitic acid.

[0074] In a specific embodiment of the present invention, the palmitic acid-containing oil contains 43% by weight and 76% by weight of palmitic acid.

[0075] In the present invention, the palmitic acid-containing fat contains 3 to 10% by weight of stearic acid, and / or 10 to 50% by wei...

Embodiment 1

[0182] Mix 700g palm stearin (iodine value IV=16) (palmitic acid 76%, stearic acid 5%, oleic acid 14%, linoleic acid 3%) and 300g palm kernel oil (lauric acid 48%, nutmeg 16% palmitic acid, 16% palmitic acid, 2% stearic acid, 16% oleic acid, 3% linoleic acid) mixed, heated to 105°C, stirred under vacuum for 30min for dehydration. Add 1 g of sodium methoxide, stir the reaction under vacuum at 105°C for 30 min, add 20 g of citric acid aqueous solution (15% by mass), and stir for 20 min to terminate the reaction. The reactant was repeatedly washed with hot water to remove soap. Heating to 105°C, stirring in a vacuum for 30 minutes for dehydration and drying to obtain transesterified oil.

[0183] Take 500g of the above-mentioned transesterified oil and 1000g of fatty acids derived from high oleic sunflower oil (5% palmitic acid, 1% stearic acid, 80% oleic acid, 11% linoleic acid) and mix them, and pass them through at a flow rate of 200g / h An enzyme column filled with 100 g of Li...

Embodiment 2

[0185] Mix 500g palm stearin (iodine value IV=16) (palmitic acid 76%, stearic acid 5%, oleic acid 14%, linoleic acid 3%) and 500g palm kernel oil (lauric acid 48%, nutmeg 16% palmitic acid, 16% palmitic acid, 2% stearic acid, 16% oleic acid, 3% linoleic acid) mixed, heated to 105°C, stirred under vacuum for 30min for dehydration. Add 1 g of sodium methoxide, stir the reaction under vacuum at 105°C for 30 min, add 20 g of citric acid aqueous solution (15% by mass), and stir for 20 min to terminate the reaction. The reactant was repeatedly washed with hot water to remove soap. Heating to 105°C, stirring in a vacuum for 30 minutes for dehydration and drying to obtain transesterified oil.

[0186] Get 500g of the above-mentioned transesterified oil and 500g derived from rapeseed oil fatty acid mixture (palmitic acid 4%, stearic acid 2%, oleic acid 61%, linoleic acid 20%, linolenic acid 8%) mix, according to 100g / The flow rate of h passes through the enzyme column filled with 10...

Abstract

The present invention relates to a grease composition, a breast milk fat substitute, and preparation methods of the grease composition and the breast milk fat substitute. The preparation method of the grease composition or the breast milk fat substitute comprises: (1) carrying out random transesterification on a grease containing palmitic acid and a grease containing lauric acid and / or myristic acid to obtain a transesterified grease; and (2) carrying out a reaction on the transesterified grease obtained in the step (1) and a unsaturated-fatty-acid-containing mixture of fatty acid or an ester thereof in the presence of a lipase. With the preparation method of the present invention, the grease composition or the breast milk fat substitute having the fatty acid composition or the position distribution thereof more completely close to the breast fat can be obtained.

Description

technical field [0001] The invention relates to an oil composition, a breast milk fat substitute, and a preparation method thereof. Background technique [0002] Breast milk is the best natural food source for infant growth and development, and is the gold standard in infant nutrition. Breast milk contains 3% to 4.5% fat, of which triglycerides account for more than 98%. These fats provide infants with 50% to 60% of energy and essential fatty acids needed for growth and development, and at the same time promote the absorption of fat-soluble vitamins. function. [0003] Breast milk fat has a unique fatty acid composition and its position distribution on the triglyceride skeleton. Breast milk samples from different countries have great differences in the types of fatty acids. Table 1 summarizes the main fatty acid composition and distribution of mature breast milk in Guangdong, China (Wang Y H, Mai Q Y, Qin X L, et al. Establishment of an evaluation model for human milk fat ...
