Abstract
The present invention discloses a new technology for extracting vitamin E and sterol from the deodorization distillate of vegetable oil, which belongs to the technical field of biochemical engineering. In the technology, lipase is used as a catalyst to replace conventional strong acid and strong alkali; fatty acid and neutral grease in the deodorization distillate of vegetable oil are catalyzed by the lipase used as the catalyst at normal temperature and pressure to simultaneously carry out a transecterification reaction so as to generate fatty acid monoesters; based on the characteristic that vitamin E and sterol are easy to separate from the fatty acid monoesters, the vitamin E and the sterol are separated and extracted by a conventional rectifying technology. The technology can simultaneously convert the fatty acid and the neutral grease into the fatty acid monoesters once, and therefore, operating steps are greatly simplified. Additionally, conditions in the whole reaction process are mild, and the lipase is easy to separate from a reaction system and can be repeatedly used multiple times.

Technical field
The invention belongs to technical field of biochemical industry.Be particularly related to a kind of novel process of extracting vitamin-E and sterol by plant oil deodorizing distillate.
Background technology
The deodorization distillate that obtains in the oil and fat refining process is the valuable source that is used to extract natural VE and sterol, and its main component is free fatty acids, neutral grease (glycerin fatty acid ester), natural VE and sterol etc.Being easy to isolating characteristics based on vitamin-E, sterol and fatty acid monoester, all is that free fatty acids in the deodorization distillate and neutral grease are converted into fatty acid monoester earlier generally, realizes further that then vitamin-E, sterol separate with above-mentioned fatty acid monoester.U.S. Pat 3335154 is first with the deodorization distillate alkali soapization, and then uses strong acid treatment, and neutral grease and lipid acid are changed into fatty acid methyl ester, thereby realizes the separation and Extraction of vitamin-E, sterol.Domestic patent CN1074217A utilizes the acid catalysis methyl esterification of fatty acid earlier, transforms neutral grease with alkali again and generates fatty acid methyl ester, extracts vitamin-E and sterol then.Above technology all is to use strong acid, highly basic as catalyzer, lipid acid and neutral grease are changed into fatty acid monoester after, separation and Extraction vitamin-E and sterol again.This comparatively loaded down with trivial details as the chemical technology operation of catalyzer with strong acid, highly basic, need twice conversion lipid acid and neutral grease could be transformed the generation fatty acid monoester fully.
Summary of the invention
The objective of the invention is to propose a kind of novel process of extracting vitamin-E and sterol by plant oil deodorizing distillate, it is characterized in that: utilize lipase to replace conventional strong acid, highly basic as catalyzer, normal temperature and pressure can transform the generation fatty acid monoester with lipid acid in the plant oil deodorizing distillate and neutral grease down, utilize conventional rectification technology then, realize that vitamin-E, sterol separate with fatty acid monoester, operating process is:
1. acyl acceptor short chain alcohol or short-chain aliphatic ester are mixed with plant oil deodorizing distillate, when with the short chain alcohol being the acyl acceptor of reaction, then total mol ratio of total fatty acids is 3 in short chain alcohol and the plant oil deodorizing distillate: 1-4: 1; When being acyl acceptor with the short-chain aliphatic ester, then the mol ratio of total fatty acids is 3 in short-chain aliphatic ester and the plant oil deodorizing distillate: 1-12: 1;
2. above-mentioned reactant and lipase are packed into and mix in the tool plug triangular flask, place can be temperature automatically controlled reciprocal shaking table be heated to 30 ℃～50 ℃, react after 3-24 hour, free fatty acids in the plant oil deodorizing distillate and neutral grease almost completely transform the generation fatty acid monoester.
3. utilize conventional rectification technology then, realize that vitamin-E, sterol separate with fatty acid monoester.
Described short chain alcohol is methyl alcohol, ethanol, propyl alcohol or butanols.
Described short-chain aliphatic ester is methyl-formiate, methyl acetate, ethyl formate or ethyl acetate.
Described lipase is that microbial lipase comprises Novozym435, Lipozyme TL or Lipozyme RM.
Described plant oil deodorizing distillate is soybean oil deodorizer distillate, rapeseed oil deodorization distillate, peanut oil deodorization distillate, Semen Maydis oil deodorization distillate or oleum gossypii seminis deodorization distillate.
Described fatty acid monoester is fatty acid methyl ester, fatty-acid ethyl ester, lipid acid propyl ester or fatty acid butyl ester.
The invention has the beneficial effects as follows the reaction conditions gentleness, normal temperature and pressure can transform the generation fatty acid monoester with lipid acid in the plant oil deodorizing distillate and neutral grease down, has simplified operation steps greatly; And, be easy to from reaction system, separate and can repeatedly use repeatedly as the lipase of catalyzer.The novel process that the present invention proposes, no matter from production technique still from production cost, all have fabulous prospects for commercial application.
Embodiment
