In this temperature range, the oil in peanuts is solid in theory, and the metabolism of peanuts is extremely slow, and the acid value hardly rises; However, if the temperature is lower than 0℃, freezing injury may occur and affect the taste. If the content of unhydrated phospholipids is also high after oil pressing, the relative humidity should be controlled below 85%.
