Some people say that self-squeezed oil in rural areas can't be eaten. What's wrong with self-extracting oil?

With the continuous development of science and the progress of science and technology, great changes have taken place in the pressing method of this edible oil. In order to extract more edible oil and save some costs, some oil plants have adopted "chemical extraction method" to process various oils. About a week later, my daughter-in-law and my mother-in-law made a video to greet the situation at home, and then my mother-in-law talked about peanuts. This time, the peanuts have been dried for us, and we are going to take them to the village oil mill to help us squeeze peanut oil.

People living in rural areas have seen the production process of self-squeezing oil more or less, and all of them adopt the method of physical squeezing. Raw materials are handed over to the oil mill for processing, and the oil is basically heat-treated (or fried or steamed) first, then put into the press, and the oil is squeezed out by the pressure in the press chamber, and then it can be packaged and taken home for use. Aflatoxin is highly toxic, difficult to decompose, slightly decomposed in strong acid solution, rapidly decomposed in strong alkali solution, and resistant to high temperature. The decomposition temperature of aflatoxin is 268℃, and ultraviolet rays are destructive to low concentration of aflatoxin, which can damage human liver. It is also a strong carcinogen.

Unlike specialized companies that have processing technology to further treat moisture and impurities, the squeezed peanut oil and rapeseed oil are taken home by farmers, and then the oil without obvious impurities is poured out and slowly heated in a clean and dry wok. As for self-squeezed oil, it is squeezed out at high temperature. How can you get it without squeezing? Large oil processing plants not only use oil presses to squeeze oil, but also are bigger, squeezing all the oil at once. It only uses means such as filtration and impregnation.

Let me give you my opinion. Oil extraction is the best, but only half of it is chemical leaching. Soybean oil is almost 100% leaching process, and the other half is half. In China, the extracted oil is allowed to be sold and eaten. Other countries may have control. Now some oil mills no longer even charge cash to farmers who come to process peanut oil, but use sesame cakes to pay for processing. Therefore, some farmers only sell sesame cakes, which saves trouble and effort. Just push the peanut oil back when you go back.
