I sell oil, let me tell you! First of all, judging from the picture, it is bulk cooking oil! It will freeze if placed in the refrigerator, which means the temperature drops below minus 3 degrees Celsius. There are generally three situations when it will freeze! One: It is pure soybean oil. Soybean oil will freeze when the temperature is below minus 3 degrees. The well-known "Arowana" 1:1:1 will also freeze in the winter, because it also contains soybean oil, but it will not be like yours. That oil freezes so well, it’s just a little bit! It’s not obvious, and you can’t see it unless you look carefully! If it is soybean oil, it will not affect consumption! Two: Even peanut oil will freeze. I think the owner of your canteen will never buy oil as good as peanut oil for cooking! Three: Palm oil is added to it! Adding palm oil will also freeze it, just like the German one in the picture, it freezes so badly! However, palm oil does not affect consumption! This is only added by the manufacturer to reduce production costs, because the price of palm oil is much lower than that of other oils! But then again, the hygienic situation of bulk oil is very bad, really bad. If you buy oil at home, I suggest you buy small packages of cooking oil. No matter what brand it is, it is better than bulk cooking oil. Hygiene is better, even several times better!
