Abstract

The invention discloses a production method for medium-chain and long-chain oil fatty acid. The production method comprises the following steps: carrying out transesterification reaction, saturated alkaline water neutralization, adsorbent desoaping, vacuum flashing and the like to medium-chain fatty acid triglycerides of C6-C12 and long-chain fatty acid triglycerides of C16-C24 in a reactor filled with lipase, to obtain the long-chain oil fatty acid in the product. The method solves the difficulty that the medium-chain and long-chain oil fatty acid in the prior art is complicated, and has the characteristics of being short in reaction time of the reactor, and low in energy consumption.

Description

technical field [0001] The invention relates to the field of oil synthesis, in particular to a method for producing fatty acid triglycerides. Background technique [0002] Medium- and long-chain fatty acid oils are medium- and long-chain fatty acid triglycerides (MLCT), which are new functional oils obtained by combining medium and long-chain fatty acids on triglycerides. It has the characteristics of being directly absorbed by the human portal vein into the liver to quickly replenish the body with energy and nutrition, without burdening the intestines, and can effectively reduce the concentration of total cholesterol and low-density lipoprotein, and play a role in weight loss, prevention and treatment of diabetes and hyperlipidemia and other metabolic diseases. The prior art generally adopts the transesterification process to produce medium and long-chain fatty acid oils, that is, uses medium-chain fatty acid triglycerides and long-chain fatty acid triglycerides to realize...
