How much oil can a catty of peanuts squeeze out?

A catty of peanuts can squeeze out four taels of oil.

Generally, the oil yield of peanuts is 40%-45%, and the oil yield of a kilo of peanuts is different with different oil presses. Squeezing with an oil press can squeeze 4 liang of peanut oil. Squeezing with a press can squeeze out 4.3 taels, of which 0.3 taels are ground peanuts. After 2-3 weeks of precipitation, the peanut kernel is removed, and the peanut oil obtained is also 4 Liang. 3.7-3.8 kinds of peanut oil can be squeezed by traditional vertical oil press.

The output of self-pressed peanut oil is different from that of brand oil. Because of the different equipment and raw materials, the oil yield of self-squeezed peanut oil will be less than that of brand oil for the same kilogram of peanuts.

Preservation method of peanut oil

1. Choose a suitable container: Most of the peanut oil we buy in the market is packed in plastic barrels. If we want to preserve peanut oil for a long time, we should transfer it to a glass container or a ceramic container.

2. Sealed storage: Peanut oil must be sealed when stored, because if peanut oil is in direct contact with air, moisture and oxygen in the air will penetrate into peanut oil, thus accelerating its decay rate.

3. Avoid high temperature: When many people store peanut oil, they will put it near the stove, which is very dangerous. First, there is a fire hazard, and second, it will accelerate the deterioration of engine oil.
