Abstract

The invention relates to a removing technology of aflatoxin in corn oil, and belongs to the technical field of oil processing. The removing technology comprises the following steps: selecting and storing corn germs; treating the selected corn germs to obtain crude oil; sequentially carrying out alkali refining, dewaxing, decoloration and deodorization on the crude oil, as so to finally obtain the finished product, namely, corn oil, wherein a compound adsorbing agent is adopted during decoloration; the compound adsorbing agent is a mixture of activated clay, attapulgite and activated carbon. According to the removing technology, aflatoxin removal and the whole corn oil producing process are organically combined, so that the aflatoxin content in the corn oil is decreased, and substances and procedure devices are not externally added; the removing technology is environment-friendly and safe; the original nutritional components in the corn oil are maximumly reserved.

Description

technical field [0001] The invention relates to a process for removing aflatoxin in corn oil, belonging to the technical field of oil processing. Background technique [0002] Aflatoxin is a carcinogen produced by a series of mold metabolism, mainly polluting grain, oil, food, animal and plant food, such as peanuts, corn, rice, wheat, beans, nuts, meat, milk and dairy products, aquatic products, etc. All may have aflatoxin contamination, among which peanut and corn contamination is the most serious. Aflatoxins B1 and B2 are blue under ultraviolet light, and G1 and G2 are green fluorescence. In 1993, aflatoxin was identified as a class I carcinogen by the Cancer Research Institute of the World Health Organization, especially aflatoxin B1, which is the most toxic and carcinogenic. [0003] Aflatoxin mainly damages the liver tissue of humans and animals, manifested as swelling of liver cell nuclei, steatosis, hemorrhage, necrosis, and hyperplasia of bile duct epithelium and f...
