Abstract

The invention discloses a method for conjugation of Idesia polycarpa oil and purification of conjugated linoleic acid, and relates to the technical field of purification of the conjugated linoleic acid. The Idesia polycarpa oil is prepared through the following steps: subjecting prepared crude Idesia polycarpa oil to ultrasonic-assisted phospholipase C degumming treatment, and after degumming is completed, carrying out centrifugal separation so as to obtain degummed Idesia polycarpa oil; placing the degummed Idesia polycarpa oil, propylene glycol and an inorganic strong basic catalyst into a container, and introducing nitrogen gas into the container; subjecting the degummed Idesia polycarpa oil, propylene glycol and the inorganic strong basic catalyst to a reaction under heating under the action of light wave, wherein the light-wave power is 300 to 500 W, and duration time is 1 to 1.5 hours; subjecting a reaction material to cooling to room temperature, then carrying out stirring under the protection of nitrogen gas, and adding a strong acid so as to reduce the pH value of the reaction material to 4 to 5; transferring the reaction material into a liquid distribution vessel, carrying out standing for half an hour, and discharging waste liquid at the bottom layer; and carrying out repeated washing with distilled water until the pH value of the washing water is 6 to 7, and removing impurities so as to obtain the conjugated linoleic acid. The method provided by the invention has the following advantage: the time of purification is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of jatropha oil refining, in particular to a method for conjugating jatropha oil and purifying conjugated linoleic acid. Background technique [0002] Conjugated linoleic acid (CLA) is an isomer of linoleic acid, which is a series of positional and geometric isomers of linoleic acid with double bonds at carbon 9, 11 or 10, 12. Constructs are nutritional elements commonly found in humans and animals. A large number of scientific studies have proved that conjugated linoleic acid has many important physiological functions such as anti-tumor, anti-oxidation, anti-atherosclerosis, improving immunity, increasing bone density, and preventing and treating diabetes; it can also reduce animal and human cholesterol and Triglycerides and low-density lipoprotein cholesterol can also reduce animal and human fat and increase muscle. [0003] Application No. 2008100463351 discloses a method for preparing conjugated linole...
