Did you buy peanut oil? If so, that's normal. The freezing point of peanut oil is 0 to 3 degrees Celsius, so peanut oil is easy to precipitate in winter. The inspection method of adulterated edible peanut oil can be identified by smell, that is, drop one or two drops of oil on the palm of your hand with chopsticks or spoon, rub it until the palm is hot, and put it in front of your nose to smell. Peanut oil without adulteration can smell a strong peanut fragrance, while peanut oil with essence has a slight peanut fragrance at first, but with kneading again, the peanut fragrance will become weaker and weaker.
