Problems solved by technology

Palm oil is semi-solid to solid at room temperature. If it is used as a raw material for the production of plastic oil, although it can solve the above-mentioned requirements of solid fat content SFC and low trans, it also brings some problems, such as reducing the crystallization of oil The speed greatly prolongs the final aging step of plastic oil production (that is, the cooling and crystallization of finished oil products, usually at room temperature), reduces production efficiency, and brings inconvenience to the industrial production of plastic oil
[0006] In addition, according to the description of patent CN 97118508.5, the fat obtained by mixing butter or fractionated fat through transesterification and adding it to palm stearin can also increase the crystallization speed, but because butter contains cholesterol, it is helpful to induce heart disease. Vascular disease and therefore not recognized by society
[0007] Patent JP2007271865A and Chinese patent application 201110081218.0 whose inventor is Hu Yongtao also propose a solution to increase the crystallization speed, but both require a higher content of C12-14 and a large amount of palm kernel oil

[0171] Preparation method of plastic oil product

[0172] The present invention also provides a method for preparing the plastic oil product of the present invention, the method comprising:

[0173] (i) provide the grease composition of the present invention;

[0174] (ii) The oil composition is subjected to a post-processing step including an aging step to obtain the plastic oil product.

[0175] In a specific embodiment of the present invention,

[0176] In the step (ii), the curing time is: the curing time is between 10 minutes and 2 days at 10-35 degrees.

[0177] In a specific embodiment of the present invention,

[0178] In the step (ii), the curing time is: the curing time is between 10 minutes and 36 hours at 10-35 degrees.

[0179] Of course, the upper limit of the aging time in the present invention may be higher, and may be, for example, 10 minutes to 3 days. But the advantage of the present invention is that it can save curing time without affecting other perf...

Embodiment 1-1

[0196] MCT [IV: 0, C8 60%, C10 40%, purchased from Corning Chemical (China) Co., Ltd.] and extremely hydrogenated palm oil [IV: 0.5, purchased from Kerry Special Oils (Shanghai) Co., Ltd.] = 33: 67 is formed by transesterification, refining, quenching and kneading.

[0197] Vacuum dry the mixed oil and fat raw materials (stir in vacuum, heat up to 105°C, keep for 15min); then add 0.8% catalyst sodium methoxide, react at 100°C for 45min; then add 8% citric acid aqueous solution, stir for 30min, The reaction was terminated, and then the reactant was washed with water until the pH was 7, and then centrifuged to obtain transesterified oil.

[0198] Then carry out oil refining operation on the obtained transesterified oil: vacuumize and heat the transesterified oil to 105°C, keep it for 30min, dehydrate and dry; then add 2% activated clay, keep it at 110°C for 30min for decolorization, add diatomaceous earth filter to obtain transesterified oil. Finally, vacuumize at 240°C and de...

Abstract

The invention provides a grease composition, which comprises a triglyceride composition obtained by an ester exchange treatment. In terms of the weight of the total fatty acids constituting the grease composition, the content of saturated fatty acid is 30%-100%; in terms of the weight of the total fatty acids constituting the grease composition, the content of fatty acid with a carbon atom number of less than 11 is 0-60%; and in terms of the weight of the total fatty acids constituting the grease composition, the content of fatty acid with a carbon atom number of greater than 19 is 0-60%. The invention also provides grease prepared from the grease composition and a preparation method thereof. The grease composition provided in the invention has a low content of trans-fatty acids, a solid fat content in line with the requirement, a fast crystallization speed, and higher nutritive value, and can be used for making a grease composition of plastic grease.

Description

technical field [0001] The invention relates to an oil composition; more specifically, it relates to a plastic oil composition with low trans fatty acid content and fast crystallization rate. Background technique [0002] For industrial production of oil compositions, especially plastic oil compositions such as margarine and shortening, in order to meet specific application requirements, it is usually necessary to meet certain operational performance indicators. For example, one of the more important performance indicators is solid fat Content (Solid Fat Content, SFC), specifically, refers to the melting and hardness performance indicators of fat at different temperatures, and the melting and hardness performance have a great influence on the production and application of plastic fats, and the taste, fragrance and spreadability of products, etc. have a great impact. [0003] As far as the current technical level is concerned, in order to meet the requirements of specific so...
