Abstract

The invention relates to a method for removing mycotoxin in vegetable fat and application device. According to the method, new processing equipment and technologies are adopted in two working sections, wherein in one working section, after caustic soda liquid deacidification is carried out, a vegetable oil detoxification device is used for carrying washing detoxification treatment on vegetable oil alkali oil refining, and in the adsorption and decoloration working section of alkali oil refining, a vegetable oil microwave processing adsorption detoxification device is used for specific adsorption and detoxification of mycotoxin. The method has the advantages that the content of the mycotoxin in the treated vegetable fat can be controlled at a not-detected level (the detection limit is 2mu g/kg), meanwhile, the molecular structure of the processed fat is unchanged, pollutants are not brought in, the nutrition and flavor of the fat are unchanged, and the method is suitable for continuous refinement production.

Description

technical field [0001] The invention relates to a method and an application device for removing mycotoxins from vegetable oil, belonging to the technical field of oil processing. Background technique [0002] Mycotoxins are toxic secondary metabolites produced during the growth of molds, with molecular weights ranging from several hundred to several thousand Daltons. They have no resistance, but are thermally stable and generally not destroyed by heating. Its existence on earth is even longer than that of human beings. Although no major disasters have been caused by the accumulation of mycotoxins in the world, its harm to agricultural production and food safety cannot be underestimated. Mold is a multicellular microorganism that can reproduce in two forms: seeds or spores. In favorable conditions, it reproduces as seeds; in unfavorable conditions, it reproduces as spores. One type of mold can produce multiple mycotoxins, and different molds can also produce one type of my...
