Embodiment 1

[0142] Example 1: Oil and fat mixing ratio design and property analysis of chemical transesterification products

[0143] The acid value (AV) and the peroxide value (PV) of raw material oil and fat used in the following examples palm olein (OL), fully hydrogenated soybean oil (FHSBO), canola oil (canola), tallow and peroxide value (PV) are as in table 1 Shown:

[0144] Table 1. Physical and chemical indicators of raw oils and fats

[0145]

[0146] According to the fatty acid composition of three selected vegetable oils OL, FHSBO and Canola and tallow, the mixing ratio of vegetable oil with fatty acid composition close to that of tallow was designed. In this embodiment, three kinds of proportioning are selected:

[0147] Sample 1 - OL:FHSBO:Canola = 50:25:25,

[0148] Sample 2 - OL:FHSBO:Canola = 60:20:20,

[0149] Sample 3-OL:FHSBO:Canola=70:15:15.

[0150] The specific results are shown in Table 2.

Embodiment 2

[0167] Embodiment 2. Utilize three kinds of vegetable oil mixtures and two kinds of vegetable oil mixtures with fatty acid composition similar to tallow to prepare transesterified oil

[0168] In this example, another ratio of palm olein, fully hydrogenated soybean oil and canola oil with fatty acid composition similar to that of tallow was designed, namely OL:FHSBO:Canola=55:30:15 (sample 4). In addition, the present application also designed a scheme of only palm olein and fully hydrogenated soybean oil raw materials whose fatty acid composition is similar to tallow, and its proportion is OL:FHSBO=80:20 (sample 5). The above two schemes and the fatty acid composition of tallow are shown in Table 5.

Embodiment 3

[0183] Example 3. Proportion optimization of palm olein, fully hydrogenated soybean oil and canola oil and property analysis of transesterification products

[0184] The results of samples 1-3 in Example 1 were analyzed and optimized in detail. Further optimization was carried out according to the ratio of samples 2 and 3, and scheme 1 was obtained: OL:FHSBO:Canola=62:22:16. In addition, the proportion of sample 1 was retained as scheme 2: OL:FHSBO:Canola=50:25:25.

[0185] The chemical transesterification reaction was carried out according to the above mixing ratio and the chemical transesterification reaction described in the "Materials and Methods" section involved in Example 1 to obtain transesterification products.

Abstract

The present invention discloses a method of preparing oil composition. The prepared oil composition can be used as a substitute of beef tallow. The method comprises the following steps: a vegetable oil mixture is subjected to transesterification under the presence of catalysts, wherein the vegetable oil mixture comprises palm olein, fully hydrogenated soybean oil and canola oil. The present invention also discloses the prepared oil composition and uses of the prepared oil composition.

Description

field of invention [0001] This application relates to the field of manufacture of fats and oils. Specifically, the present application relates to the use of vegetable oil mixture and transesterification to improve the quality of oil. The prepared oil can be used as, for example, a butter substitute, and can be used to make, for example, margarine or shortening. Background of the invention [0002] Margarine and shortening are two plastic fat products widely used in the food industry and catering industry. They have the functions of providing food shape and making pastry crispy. The earliest margarine was prepared from butter, and early shortening was also produced from common animal fats such as butter and lard [1] . [0003] Because butter can form β′ crystal form, there is no problem of post-crystallization and post-hardness. At the same time, butter has a good flavor and can bring good aroma when used in baked products, so butter is very suitable for margarine / starting...
