What's the difference between crude oil and cooked oil?
As far as soybean oil itself is concerned, there is no distinction between raw and cooked. Regarding soybean oil, I can make an analogy with water. The so-called cooked soybean oil is like boiled tap water, while raw soybean oil means that tap water is not boiled. If you think the so-called cooked soybean oil has an odor, the same is true. There is no difference in the smell of salad oil, which is relatively pure soybean oil. The smell of cooked soybean oil is actually the smell formed by impurities in soybean oil after high temperature. Just like the pure water we drink, the temperature of boiled water and cold water has not changed except after heating and without heating. Therefore, qualified soybean oil is raw and cooked.
