Embodiment 1

[0099] Grease Composition 1

[0100] Mix palm olein stearin with IV=14.4 and high oleic sunflower oil in a ratio of 3:1, heat up to 105°C, and at the same time vacuumize and stir, keep for 1 hour, and dehydrate; add the weight of the above mixture into 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%) by weight of the above mixture, and continue stirring for 20 minutes to terminate the reaction. Wash the reactant with water until pH = 7, remove soap, then heat to 105°C, keep for 30 minutes for dehydration and drying; add 2% activated clay by weight of the above-mentioned dehydrated and dried mixture, and keep at 110°C for 30 minutes for decolorization, Filter to obtain transesterified oil. Finally, the obtained transesterified oil was deodorized at 240° C., 2 mbar and blown with nitrogen for 3 hours to obtain refined oil. The refined oil is mixed with oleic acid in a r...

Embodiment 2

[0111] Grease Composition 4

[0112] Mix palm stearin with IV=22 and high oleic acid sunflower oil at a ratio of 3:1, add 6% (weight) lipase LipozymeTLIM, and stir at 65°C for 24 hours to carry out randomization reaction. The lipase is then filtered to physically refine the oil. It includes adding 2% active clay by weight to the enzymatic transesterification mixture, maintaining it at 110°C for 30 minutes for decolorization, filtering, and finally deodorizing the obtained transesterified oil at 240°C, 2mbar and blowing nitrogen for 3 hours before refining grease. Finally, the refined oil and oleic acid were mixed in a ratio of 1:2 and then passed through a packed bed containing 100g LipozymeRMIM lipase for enzymatic directional transesterification, wherein the temperature of the mixture and lipase was 60°C. The directional transesterification mixture obtained by the reaction was subjected to molecular distillation under reduced pressure to remove the fatty acid therein to fi...

[0122] Fat Composition 7

[0123] Mix palm stearin with IV=34.6 and high oleic sunflower oil in a ratio of 4:1, heat up to 105°C, and at the same time vacuumize and stir, keep for 1 hour, and dehydrate; add the weight of the above mixture into 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%) by weight of the above mixture, and continue stirring for 20 minutes to terminate the reaction. Wash the reactant with water until pH = 7, remove soap, then heat to 105°C, keep for 30 minutes for dehydration and drying; add 2% activated clay by weight of the above-mentioned dehydrated and dried mixture, and keep at 110°C for 30 minutes for decolorization, Filter to obtain transesterified oil. Finally, the obtained transesterified oil was deodorized at 240° C., 2 mbar and blown with nitrogen for 3 hours to obtain refined oil. The refined oil is mixed with oleic acid in a ratio of 1...

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% ...
