Soybean oil refining by-products was used to extract the natural tocopherol as food antioxidants and the market of all kinds of food additives and other commonly used antioxidants are compared, and the oxidation resistance of natural tocopherol, antioxidant activity were studied.It is concluded that the soybean oil refining by-products extracted natural tocopherol its antioxidant function are superior to synthetic standard tocopherol and other antioxidants, for the extraction of soybean oil refining by-products of natural tocopherol as a food additive to provide a theoretical basis and development prospects.palm oil millﾧ,Currently exploring new oil refining method is meaningful.To comprehensively in this paper, the refining, best starts until making oil packing, however, this article mainly related refining degumming, acid, decoloring, deodorization process.A, degumming process of refining, degumming process cannot be ignored.Most need vegetable oil degumming.Physical refining to degum, especially production of lecithin, degumming condition is strict.Not only is the separation of colloid, and at the same time the sales standard lecithin.draught fanﾧ，Edible oil refining technology has become mature, but the environmental pollution and energy consumption problem is still outstanding, the introduction of high-end devices, though can achieve energy conservation and emissions reduction, but not fundamentally improved.Aiming at these problems, mainly from the selection of oil refining production process, highly automated control and production equipment of oil refining plant energy conservation and emissions reduction are analyzed and discussed.With the development of social economy and the continuous improvement of people's living standard, the idea of people start to eat satisfied to eat well, more attention to the nutritional and safety of edible oils and fats.For making oil raw materials, oil production in the use of oil products and the custody of each link,...
