[0098] Example 1

[0099] Grease composition 1

[0100] Mix palm oil stearin with IV=14.4 and high oleic sunflower oil in a ratio of 3:1, heat to 105°C, vacuum and stir at the same time, keep it for 1 hour, and dehydrate; add the above mixture weight to the transesterification tank 0.5% sodium methoxide as a catalyst, react at 80°C for 45 minutes; then add 20% citric acid aqueous solution (concentration 8%) of the above mixture weight and continue stirring for 20 minutes to terminate the reaction. Wash the reactant with water to pH=7, desoap, and then heat to 105°C for 30 minutes to dehydrate and dry; add 2% activated clay by weight of the mixture after dehydration and drying, and keep it at 110°C for 30 minutes for decolorization. Filter to obtain transesterified grease. Finally, the obtained transesterified grease was deodorized at 240°C, 2mbar and nitrogen blowing for 3 hours to obtain refined grease. The refined oil and oleic acid were mixed in a ratio of 1:2 and passed thro...

[0111] Grease composition 4

[0112] Mix palm oil stearin with IV=22 and high oleic sunflower oil in a ratio of 3:1, add 6% (weight) lipase Lipozyme TL IM, and stir at 65°C for 24 hours for randomization reaction. Then the lipase is filtered and the fat is physically refined. Including adding 2% by weight of activated clay to the enzymatic transesterification mixture, decolorizing by keeping it at 110°C for 30 minutes, filtering, and finally deodorizing the obtained transesterified grease at 240°C, 2mbar and nitrogen blowing for 3 hours to obtain refining grease. Finally, the refined oil and oleic acid were mixed in a ratio of 1:2 and passed through a packed bed filled with 100g Lipozyme RM IM lipase for enzymatic directional transesterification. The temperature of the mixture and lipase was 60°C. The directional transesterification mixture obtained by the reaction was subjected to reduced pressure molecular distillation to remove fatty acids therein, and fina...

Abstract

The invention relates to relates to a method for preparing a composition containing 1,3-di-unsaturated fatty acyl-2-saturated fatty acyl glyceryl ester, particularly containing 1,3-di-oleoyl-2-palmitoyl glyceryl ester (OPO), which comprises the steps of: carrying out random ester exchange on an ester rich in saturated fatty acid residue and an ester rich in unsaturated fatty acid residue serving as reaction substrates, and carrying out enzymatic oriented ester exchange on the reaction mixture and unsaturated fatty acid or unsaturated fatty acid ester. The invention also provides application of the composition to preparing formula milk powder for infant and preparing synthetic food for infant, and the formula milk powder for infant and the synthetic food for infant containing the composition.

Description

technical field [0001] The present invention relates to a method for preparing oil, in particular, to a composition containing 1,3-diunsaturated fatty acyl-2-saturated fatty acylglycerides, especially containing 1,3-diunsaturated fatty acyl-2-saturated fatty acylglyceride Method for the composition of oleoyl-2-palmitoylglyceride (OPO). The present invention also relates to compositions containing 1,3-diunsaturated fatty acyl-2-saturated fatty acylglycerides, in particular 1,3-dioleoyl-2-palmitoylglycerides (OPO). The present invention further relates to the use of the composition according to the invention for the preparation of infant formula, as well as for the preparation of infant formula. Background technique [0002] Breast milk is the best food for infants in the early stages of growth and development. The fat content and fatty acid composition in breast milk are suitable for the rapid growth of infants and young children. Breast milk contains about 3-4.5% fat, 98% ...
