It is important to note that the peanuts to be selected should not be moldy, because moldy peanuts contain carcinogen aflatoxin, and it is best to choose peanuts with full particles. In addition, the newly squeezed oil may not be as clear as the oil bought in the supermarket, so it needs to be allowed to stand for a while, so that the finally squeezed oil will look better.
Generally speaking, fresh hot-rolled peanut oil can be preserved for about 24 months after precipitation and filtration, and stored in a cool and dark place.
The storage of self-squeezed peanut oil is related to the moisture and colloid in the oil and the storage conditions. These conditions are difficult to control, so once we unpack peanut oil ourselves, we must pay attention to the color and smell of the oil. Once discoloration, odor or other variations are found, it is best not to eat them.
