Abstract

A preparation method of conjugated linoleic acid glycerides comprises the following steps: (1) C1-4 sodium alcoholate / potassium alcoholate is taken as a catalyst, linoleic acid short-chain alcohol ester is prepared to be conjugated linoleic acid short-chain alcohol ester through inversion reaction for 1-8 hours at 90-150 DEG C, and the using amount of the catalyst is 1.5-8.0% of weight of the linoleic acid short-chain alcohol ester; (2) sodium methylate / potassium methylate and sodium ethoxide / potassium ethoxide are taken as catalysts, the conjugated linoleic acid short-chain alcohol ester and acetoglyceride with mole ratio being 3:1-3.5:1 are reacted for 3-10 hours at 100 DEG C and 170 DEG C to prepare the conjugated linoleic acid glycerides, and the using amount of the catalysts is 0.8-10% of the weight of acetoglyceride. According to the preparation method, the natural resources are utilized sufficiently, an organic solvent is not needed in the main reaction; the esterification rate of conjugated oil acid is more than 99%; the reaction time is short, and the postprocessing simple; the triglyceride content of the conjugated linoleic acid glycerides is more than 90%, and the acid value of the conjugated linoleic acid glycerides is under 1.0mgKOH / g; and the conjugated linoleic acid glycerides is free from extraneous odor, good in taste and light in color, and the optimal Gar is less than or equal to 1.0.

Description

technical field

[0001] The invention relates to a preparation method of conjugated linoleic acid glycerides, in particular to a method for preparing conjugated linoleic acid glycerides by using short-chain alcohol esters of linoleic acid as raw materials and utilizing transposition reaction and transesterification reaction. Background technique

[0002] Conjugated linoleic acid (CLA) is an isomer of linoleic acid. A large number of in-depth studies by scientists have shown that conjugated linoleic acid and its esters and salt derivatives have the ability to reduce animal and human fat Increase muscle, reduce blood fat, resist atherosclerosis, increase bone density, regulate blood sugar, regulate blood pressure and many other important physiological functions. Therefore, conjugated linoleic acid and its esters and salt derivatives have attracted international attention in the food industry. and medical attention.
