[0136] Preparation method of oil composition

[0137] The grease composition of the present invention can be prepared by the preparation method of following grease composition, and described method comprises:

[0138] (1) Contacting and esterifying at least one fatty acid or its derivatives with at least one extremely hydrogenated oil; (2) Purifying the product obtained in step (1) by molecular distillation; (3) Purifying the product obtained in step (2) product.

[0139] The esterification step is chemical transesterification or enzymatic transesterification. The esterification step is carried out in the presence of immobilized lipase. The esterification step can be carried out by conventional methods.

[0140] In the enzymatic transesterification process, the lipase can be lipase D (Rhizopus oryzae) concentrate, purchased from Japan Amano Enzyme Co., Ltd.; or purchased from Novozymes’ Lipozyme RM IM or NS40086 (rice black Rhizomucor miehei, NS40086 Lot No. PKG211117-02),...

Embodiment 1

[0168] Enzymatic transesterification

[0169] 2.4kg of extremely hydrogenated soybean oil and 1.6kg of high oleic sunflower oil were heated and mixed at a mass ratio of 1.5:1 and placed in a 5L stainless steel jacketed reaction kettle, and TL enzyme (Lipozyme TL IM(Lipozyme TL IM( Aspergillus oryzae, Thermomyceslanuginosus, batch number LA331045)), react with 70°C, 80r / min at 80r / min for 3 hours, after the reaction is completed, the material liquid is collected by filtering through a 200-mesh stainless steel screen at the bottom of the reactor, while the immobilized enzyme remains in the reactor to continue For use, the crude reaction product was collected and mixed for purification.

[0170] Purification of triglycerides by molecular distillation

[0171] The crude product of the above reaction is molecularly distilled, and the distillation temperature is set at 210°C, the rotation speed is 300r / min, and the vacuum degree is 1×10 - 3 mbar, to remove substances such as fatt...

[0177] Enzymatic transesterification

[0178] 2.0kg of extremely hydrogenated soybean oil and 2.0kg of oleic acid were heated and mixed at a mass ratio of 1:1 and placed in a 5L stainless steel jacketed reaction kettle, and TL enzyme (Lipozyme TL IM (Lipozyme TL IM (Aspergillus oryzae, Thermomyces lanuginosus, batch number LA331045)), reacted with 70°C and 80r / min at 80r / min for 3 hours, and filtered the feed liquid through a 200-mesh stainless steel screen at the bottom of the reactor after the reaction, while the immobilized enzyme remained in the reactor for continued use. The crude reaction products were pooled for purification.

[0179] Purification of triglycerides by molecular distillation

[0180] The crude product of the above reaction is molecularly distilled, and the distillation temperature is set at 210°C, the rotation speed is 300r / min, and the vacuum degree is 1×10 - 3 mbar, to remove substances such as fatty acids, monoglycerides, or diglycerides.

Abstract

The invention relates to a fat composition. The fat composition of the invention contains triglyceride, the composition meets a condition that SSU/S2U is greater than 0.6 in weight ratio, wherein S represents the same or different saturated fatty acid residues with 12-30 carbon atoms; U represents the same or different unsaturated fatty acid residues with 16-30 carbon atoms; SSU represents the triglyceride of which the first and second positions are S and the third position is U; S2U represents the triglyceride combined with 2 molecules S and 1 molecule U. The grease composition of the invention is a grease composition of non lauric acid type, non trans-acid, non temperature adjustment and high DAG content, and has excellent properties.

Description

technical field [0001] The present invention relates to fat compositions. Background technique [0002] Cocoa butter (CB) is a vegetable fat with special composition and physical properties, which, together with cocoa powder, gives chocolate its special flavor and eating characteristics. The meltability and flavor release properties of chocolate mainly depend on the unique properties of cocoa butter. Due to the limited production of cocoa butter in the world and its high price, it is far from meeting the needs of the food industry, so cocoa butter substitutes are widely used. There are three main types. Lauric acid-type cocoa butter substitute (CBS) is made from coconut oil and palm kernel oil through fractionation or hydrogenation process. It does not need temperature adjustment, and its melting characteristics are similar to cocoa butter. Stable β' crystal form. However, CBS contains high lauric acid and is easily hydrolyzed to produce soapy taste. When it is mixed with...
