Description

Technical Field

[0001] The utility model relates to the field of peanut oil processing, in particular to a device for reducing the aflatoxin content of peanut oil. Background Art

[0002] Aflatoxins are metabolites produced by Aspergillus flavus and Aspergillus parasiticus. They are a class of compounds with similar chemical structures. The basic structure is a derivative of hydrogen furanoxanthone, containing a bifuran ring and an oxanthone. The former is a toxic structure, and the latter is related to carcinogenesis. Chemically, they can be divided into B1, B2, G1, G2, B2a, G2a, M1, M2, P1, GM2, toxic alcohol and many other types. Among various toxins, B1 is the strongest, followed by G1. Among the aflatoxin pollutants, the most common is aflatoxin B1. The toxin can be decomposed by strong alkali and oxidants, has low solubility in water, is soluble in oil and some organic solvents (such as chloroform, methanol), is insoluble in ether, is stable to heat, and has a cracking temperature of more than 280°C. Aflatoxins are widely found in moldy peanuts, corn, feed, beans, wheat and their by-products, and can also be found in fish meal, meat products, salted dried fish, milk and liver, and are toxic to many animals. When animals eat feed contaminated with aflatoxins, it may cause a decline in animal production function, immunosuppression and poisoning, affecting the output and quality of meat, eggs, milk and other products, leading to immune failure, causing diseases, and even poisoning and death. At the same time, aflatoxins remaining in meat, eggs, milk and other products can further harm the bodies of humans and animals. Continuous intake of a certain amount of aflatoxins by humans and animals can cause poisoning, mainly showing chronic damage to the liver. Long-term intake of low levels of aflatoxins or a certain amount of aflatoxins in a short period of time will cause liver cancer after a long time. Experiments have shown that aflatoxin is one of the most potent carcinogens known to date. In addition to causing liver cancer, it can also induce other tumors such as gastric adenocarcinoma, kidney cancer, and rectal cancer.

[0003] Commonly used methods for removing and degrading aflatoxin include physical, chemical and biological methods. Physical methods mainly include adsorption, irradiation, water washing, etc. In the process of treating aflatoxin, the existing equipment is prone to secondary pollution, low removal efficiency, and multiple processes. Secondly, it is easy to heat up the peanut oil during the treatment process, which is not easy to process or store later.

[0004] Therefore, a device for reducing the aflatoxin content in peanut oil is needed to solve the above problems. Utility Model Content
