Why do experts say that farm mustard seed oil is unhealthy, but many people prefer to eat it?

The safety of crushed oil in rural areas is also a problem that has been repeatedly mentioned by everyone. For example, self-squeezed peanut oil has been listed as a primary carcinogen, while glyphosate is only listed as suspected carcinogen by the international health department, which may come as a surprise to many people.

The way our ancestors used to squeeze and obtain cooking oil has been passed on for at least thousands of years, but their position has been shaken in this era of concern about food safety, and even to the point of questioning whether it is safe to eat. Here, science promotes agriculture to express a position to this.

According to today's scientific evaluation system, a large part of the reason for questioning the safety of self-extracted oil is that it contains aflatoxin. The substance is impenetrable, very invisible, and can not be detected if it does not rely on instruments and equipment after pressing. And Aspergillus flavus is listed as a primary carcinogen, which is a very clear carcinogen, such as moldy corn, peanuts and rapeseed are very prone to Aspergillus flavus.

The simplicity of traditional small-scale farmers' pressing equipment also determines the unstable safety of self-pressing oil. Now some rural press workshops already have the process of filtering Aspergillus flavus, but compared with large oil refineries, it is still very crude, and the detection stability is also very poor, and the safety risks can not be eliminated all the time.

From this point of view, there is a big gap between the safety and quality of rapeseed oil pressed by small farmers and the cooking oil produced by large factories.

So why do so many people still feel at ease about the oil they squeeze? Mainly, most farmers squeeze rapeseed or peanuts to make cooking oil for their own consumption, but before crushing, their families are very confident about the quality of their peanuts or rapeseed. If you don't believe it, ask: when these farmers go to squeeze cooking oil, who will use inferior raw materials to squeeze? Because its raw materials are full of confidence, naturally, even without Aspergillus flavus related testing equipment, they are still confident that the quality of the cooking oil they squeeze is far higher than that produced by large factories.

However, as far as the actual situation is concerned, the truth is far from this. After all, these large refineries are able to check the oil refining process or the testing equipment of oil products, and the quality is well guaranteed. We should still have confidence in the food safety of our country.
