Abstract

The invention provides an edible oil preparation method capable of effectively reducing the aflatoxin content. Nickel nitrate hexahydrate, yttrium nitrate hexahydrate, gadolinium nitrate hexahydrate,and polyacrylonitrile are used as raw materials to prepare a magnetic treating agent. Chitosan, bacillus subtilis CMCC63501, perillaldehyde, and linalool are used as raw materials to prepare an additive. The method comprises the following steps: squeezing an oil-containing plant raw material to obtain crude oil, adding the treating agent into the crude oil, adsorbing and catalytically degrading aflatoxin under a natural illumination condition, adding the additive, continuously catalytically degrading residual aflatoxin, finally enriching the treating agent by a magnet, and removing the treating agent. The aflatoxin content is effectively reduced in the edible oil production process, aflatoxin generation can be inhibited in the edible oil preservation process depending on the effect of theadditive, the aflatoxin content in the edible oil is fully controlled, and the preparation method is worthy to popularize.

Description

technical field [0001] The invention relates to the technical field of edible oil preparation, in particular to a method for preparing edible oil which can effectively reduce the content of aflatoxin. Background technique [0002] Edible oils commonly used in daily life include rapeseed oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, palm oil, sunflower oil, soybean oil, sesame oil, linseed oil (flax oil), grape seed oil, walnut oil , peony seed oil, etc. [0003] Aflatoxin has been designated as a Class 1 carcinogen by the Cancer Research Institute of the World Health Organization, and it is a highly toxic and highly toxic substance. The danger of aflatoxin is that it can damage the liver tissue of humans and animals. In severe cases, it can lead to liver cancer or even death. Aflatoxins (aflatoxins) is a group of compounds with similar chemical structures, 12 species have been isolated and identified, including b1, b2, g1, g2, m1, m2, p1, q, h1, gm, b2a and...
