由植物油精炼副产物提取天然维生素E工艺 植物油精炼时的脱臭馏出物是一种能够提取天然维生素E的宝贵资源。这种脱臭馏出物俗称“油渣”,因为其酸脂的含量较高,也有直接称为“油脂酸”的。 在单纯以精炼油脂作为极终产品的工厂里.脱臭馏出物是一种使用价值不高的副产物,以前只把它用作为粗肥皂的原料。事实上,从脱臭馏出物中不仅可以提取天然维生素E,而且还可以从中提取植物醇(phytoserol)、角鲨烯(squalence)等具有高附加值的产品。
Extraction of natural vitamin E from vegetable oil by-products Refining the deodorized distillate from vegetable oil is a valuable resource that extracts natural vitamin E. This deodorized distillate commonly known as “oil residue”, because of its high content of fat, but also directly referred to as “fat acid.” In plants that simply use refined fats as an end product, deodorized distillates are by-products of little use and were formerly used only as raw materials for crude soaps. In fact, not only natural vitamin E can be extracted from deodorized distillates, but also products with high added value such as phytoserol, squalence and the like can be extracted therefrom.
