Can moldy peanuts, soybeans, sesame and rapeseed extract oil? What kind of toxin is present?

Mildew is a common natural phenomenon, which often occurs in food. So can moldy peanuts, soybeans, sesame seeds and rapeseed still extract oil? What kind of toxin is present? What's wrong with eating it? Because food contains a certain amount of starch and protein, and more or less contains some water, and mold and eggs need the presence of water and warm temperature for growth and development. When the water activity value is low, mold and eggs can not absorb water, but when the water activity value increases after moisture, mold and eggs will absorb water in food and then decompose and eat nutrients in food.

Whether it is moldy peanuts, soybeans or sesame seeds, rapeseed are not edible, let alone extract oil!

Moldy food contains aflatoxin, the acute toxicity of aflatoxin is very strong, but also has obvious chronic toxicity and carcinogenicity. Aflatoxin is heat-resistant and rarely damaged at a general cooking temperature, and only when the temperature reaches 280℃ can it be cracked, so it should be discarded after mildew and cannot be destroyed by cooking thoroughly.

The use of moldy and deteriorated food oil can not filter the carcinogen aflatoxin in the primary oil, and long-term consumption is harmful to health. Food safety professionals remind the public to be cautious about buying self-squeezed peanut oil.

Aspergillus flavus exists in moldy peanuts, soybeans, sesame and rape seeds. Aspergillus flavus is a kind of mold that easily grows in seed foods. The most suitable temperature for the growth of Aspergillus flavus is 26 ℃-28 ℃. The higher the temperature, the faster the growth of Aspergillus flavus, and once the temperature is 28 ℃ to 33 ℃ and the humidity is 80% Mel 100, Aspergillus flavus can quickly secrete toxin. So the toxin lives in the hot and very humid south. These molds also like to grow in nuts and oily seeds.

In daily life, we should pay attention to anti-mildew and detoxification, reduce the moisture in food, and ensure that food is stored dry and ventilated, so that Aspergillus flavus is not easy to grow. We should also pay attention to the small details of food preservation: when buying food, especially when buying food raw materials such as rice, corn, peanuts, etc., we should grasp the principle of "one look, two smells, three small amounts":

1. See if there is mildew

2. Smell whether there is mildew or not.

3. Don't buy a lot at once. In addition, as aflatoxins mostly exist on the surface of grains, those that can be washed before eating and processing should be fully scrubbed and washed to remove toxins from the grain surface.
