At the same time, the lid of the container should be tightly covered to prevent air from entering and accelerate the deterioration of peanut oil.
storage characteristics
Under general storage conditions, peanut oil will undergo the process of automatic oxidation rancidity, and the changes are as follows: the automatic oxidation process is related to the season. If stored in winter, low temperature can effectively alleviate the style of lipase and oxygen. With the change of seasons and the increase of temperature, when the temperature is 15-30℃, on the one hand, oil will be hydrolyzed by lipolytic enzymes, and the acid value will increase, on the other hand, oxygen in the air will be immersed.
