The freezing point of oil is 1-3 degrees Celsius.

In some cold places, peanut oil solidification is a very normal phenomenon. Although pure peanut oil will solidify in cold environment, consumers can't pour the oil out of the bottle conveniently, which brings some trouble to use.

actually, the solution is relatively simple. After peanut oil freezes, you only need to put it in a warm environment, and it will return to its original pure state. If you want to speed up the thawing of peanut oil, you can put it in a warm air-conditioned room and give it a moderate shake. Frozen peanut oil can be used normally after thawing without affecting the taste and nutritional value at all.

Precautions for storage of edible oil

Avoid contact with air: Oil often contacts air, and the oxidation speed will be accelerated and deteriorate. It is suggested that when buying edible oil at ordinary times, dark small bottles and cans can be used to repackage oil, and the bottle cap should be tightly closed immediately after each use to avoid deterioration due to too much air contact. In addition, the shelf life of general edible oil is about 2 years, and it should be used within 3 to 6 months after opening a bottle to ensure freshness and safety.

avoid contact with water: hydrolysis is one of the reasons for oil oxidation. High water content will accelerate the activity of oxidizing enzymes, and the hydrolysis speed will be faster. Moreover, water is also conducive to microbial reproduction, which will make oil rancid and deteriorate rapidly. Therefore, when opening the bottle mouth, it is necessary to avoid dropping water into the bottle.
