Problems solved by technology

If the 2 positions are connected with medium-chain fatty acids, it will not be easy to synthesize, thereby inhibiting the accumulation of body fat, and the edible oil of polyunsaturated fatty acids is unstable and easy to oxidize at high temperature, so it is not suitable for cooking, frying, etc.

preparation example Construction

[0058] Another method for preparing the oil composition of the present invention is a chemical catalytic preparation method. The method comprises: mixing the raw oil and medium-chain triglyceride, adding a catalyst accounting for 0.1-2% by mass of the total weight of the raw material (raw oil + MCT) after vacuum drying, so that the ratio between the raw oil and the medium-chain triglyceride is about 90 React at a temperature of -120°C, add a citric acid solution with a concentration of 6-10% according to the total weight of the raw materials at 8-12% by mass to terminate the reaction, then wash the reaction product with water until the pH is neutral, dry and decolorize, and molecularly distill at 160~230°C , and deodorize to obtain the oil composition of the present invention.

[0059] In the chemical catalysis method, the molar ratio of raw oil and medium chain triglyceride is heterotrophic as defined in the enzymatic method, within the range of 0.25~1.25:1. Technicians can ...

Embodiment 1

[0076] Mix palm olein (produced by Yihai Kerry) and MCT (caprylic acid / capric acid = 60 / 40) in a molar ratio of 0.25:1, then put it into the raw material tank of the enzymatic reactor, and use 0.5 times the amount of enzyme per hour The flow rate was slowly passed through a packed column filled with 2wt% of the total weight of raw materials lipase (Lipozyme RM IM), and the transesterification reaction was carried out at 30°C. The reaction product was molecularly distilled at 160°C, decolorized and deodorized to obtain oil composition 1.

Embodiment 2

[0078] Mix rapeseed oil (produced by Yihai Kerry) and MCT (caprylic acid / capric acid = 60 / 40) in a molar ratio of 0.5:1, and then put it into the raw material tank of the enzymatic reactor, and use 2 times the amount of enzyme per hour The flow rate was slowly passed through the column filled with lipase (Lipozyme TL IM) added with 10wt% of the total weight of raw materials, and the transesterification reaction was carried out at 60°C. The reaction product was molecularly distilled at 190°C, decolorized and deodorized to obtain oil composition 2.

Abstract

The invention relates to a grease composition for preventing an obesity fatty liver and a preparation method thereof. Specifically speaking, a medium-chain fatty acid in the grease composition provided by the invention accounts for 25 to 35% by mass of all the fatty acids in the grease composition; triglyceride containing two medium-chain fatty acid residues in its molecule accounts for no less than 30% by mass of all the triglycerides; and a long-chain saturated fatty acid accounts for no more than 15% by mass of all the long-chain saturated fatty acids composing the grease composition. The grease composition provided by the invention can reduce triglycerides in the liver, improve metabolism of lipoprotein and prevent occurrence of an obesity fatty liver, has same cooking applicability as common edible oil, good taste and high security and is applicable to edible oil, fat or grease processed food, etc.

Description

technical field [0001] The invention belongs to the field of edible oil, and in particular relates to an oil composition for preventing obese fatty liver and a preparation method thereof. Background technique [0002] Fat is one of the important sources of human energy and can provide essential fatty acids, which is beneficial to the digestion and absorption of fat-soluble vitamins. However, excessive intake of fat is a risk factor for obesity, hyperlipidemia, atherosclerosis and other chronic diseases one. According to the 2002 survey on nutrition and health of Chinese residents, the average daily intake of cooking oil for urban and rural residents in my country is 42g, which is much higher than the recommended amount of 25g in the 1997 Dietary Guidelines for Chinese Residents. Meanwhile, the prevalence of related chronic diseases is increasing rapidly. Compared with 1992, adult overweight increased by 39%, obesity increased by 97%, and the prevalence of hypertension incre...
