天然维生素E的提取工艺与行业发展

Extraction Process of Natural Vitamin E and Industry Development

天然维生素E是一种在很多方面有重要用途的生育酚。其主要是从精炼食用植物油过程中产生的副产物—脱臭馏出物中提取的,提取过程主要有三个阶段:原料预处理、VE提取和产品精制;提取的方法主要有:蒸馏、精馏、吸附分离、溶剂萃取等。30余年来,中国天然维生素E行业从学习、消化、吸收国外先进技术起步,一直发展到今天,已经可以与国外巨头如BASF、ADM等竞争,并逐渐形成了一个良性的松散型联盟,同时,行业在不断发展过程中,也不断产生新的需求和方向,将其进行总结,可以为行业后续更好的发展提供参考和借鉴。

Natural vitamin E is an important tocopherol,which is mainly extracted from the by-product of edible vegetable oil refining processdeodorization distillation.The extraction process mainly includes three stages:Raw material pretreatment,vitamin E extraction and product refining;The separation methods involved are mainly:Distillation,solvent extraction,adsorption,etc.Over the past 30 years,China's natural vitamin E industry has started from learning,digesting and absorbing foreign advanced manufacturing technology,and developed until today.It has been able to compete with foreign giants such as BASF and ADM and has formed a benign loose alliance.During this process,the industry has made arduous efforts and received profound lessons.At the same time,in the process of continuous development of the industry,there are also new directions and new demands.Summarizing them can provide some enlightenment for the subsequent entrants of the industry.
