[0244] Preparation method of oil composition

[0245] The preparation method of oil composition of the present invention, described method comprises:

[0246] (1-a) contacting and esterifying at least one fatty acid or its derivative (a1) with at least one extremely hydrogenated oil (a2);

[0247] (2-a) purifying the product obtained in step (1-a) to obtain transesterified oil A;

[0248] (1-b) contacting and esterifying at least one fatty acid or derivative thereof (b1) with at least one palm fractionated stearin or palm transesterified oil (b2);

[0249] (2-b) purifying the product obtained in step (1-b) to obtain transesterified oil B;

[0250] The StStO / StO of the transesterified grease A is 0.5~1;

[0251] The PPO / P2O of the transesterified fat B is 0.4~1,

[0252] The fat composition is obtained by mixing 45 to 100% by weight of the transesterified fat A and 0 to 55% by weight of the transesterified fat B.

[0253] The esterification step is chemical transesterifica...

Embodiment

[0282] The present invention will be further described below through specific examples, but the protection scope of the present invention will not be limited. Conventional instruments and equipment in the art are used in the following examples. For the experimental methods without specific conditions indicated in the following examples, the conventional conditions or the conditions suggested by the manufacturer are usually followed. Various starting materials were used in the following examples, and unless otherwise stated, conventional commercially available products were used. In the description of the present invention and the following examples, unless otherwise specified, "%" means percentage by weight.

[0283] Extremely hydrogenated soybean oil (purchased from Yihai Kerry Marketing Co., Ltd., iodine value is approximately 0), palm oil fractionated stearin (Hard ST, purchased from Yihai Kerry Marketing Co., Ltd., iodine value is about 15), Hard ST fraction Stearin (pur...

[0287] Preparation of transesterified fat A

[0288] Enzymatic transesterification

[0289] 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 LA331616)), reacted with 70°C, 80r / min at 80r / min for 3 hours, and collected the feed liquid through a 200-mesh stainless steel screen at the bottom of the reaction kettle after the reaction, while the immobilized enzyme remained in the reaction kettle for continued use. The crude reaction products were pooled for purification.

Abstract

The invention relates to a grease composition and a preparation method thereof. The grease composition is characterized by containing a glyceride mixture, and by satisfying any of the following conditions in terms of the total weight ratio of the grease composition: (1) SSS is 0-10 wt%; (2) S2U is 75 to 95 wt%; (3) SUS is less than 30 wt%; (4) PPO / StStStO is greater than 0 to 1.0 by weight ratio;and (5) the weight ratio of (PStO + StPO) / POSt is 1 to 35. The symbols are as defined in the specification. The grease composition disclosed by the invention is a non-lauric acid, non-trans and non-temperature-regulating grease composition, and has the characteristics of remarkably improving the heat resistance, frosting resistance, good taste and other qualities of foods. The invention also provides a preparation method of the grease composition.

Description

technical field [0001] The invention relates to an oil composition and a preparation method thereof, in particular to a chocolate oil composition and a preparation method thereof. Background technique [0002] Cocoa butter (CB) is a vegetable fat with special composition and physical properties, which together with cocoa powder endow chocolate with 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. The melting properties of lauric cocoa butter substitute (CBS) are similar to those of cocoa butter, and the homogeneous polymorphic form is simple. The processing process does not require temperature adjustment, and can be directly crystallized into a stable β' crystal form, which can completely re...
