Why is peanut oil steamed before pressing?

In peanut oil pressing lines, the raw materials need to be steamed before pressing. Why is peanut oil steamed before pressing?

Steaming is one of the important processes in the oil making process. The steaming of peanut embryos refers to the process of wetting, heating, steaming embryos, frying embryos, etc., so that the internal structure of the peanut embryos is changed and the mature embryos are transformed. The purpose of steaming is to completely destroy the oil cells, protein denaturation, oil aggregation, grease viscosity and surface tension are reduced through the action of temperature and moisture, and the elasticity and plasticity of the material embryo are adjusted, which is conducive to the smooth progress of the oil making process. At the same time, the quality of the steaming effect directly affects the oil yield of peanut pressing and the quality of wool oil and cake meal.

What do I need to pay attention to during the steaming process?

In the process of frying, it is necessary to pay attention to grasping the heat and time, and observe whether the temperature and moisture of the peanut kernels are in good condition, and the oil molecules on the hot material are the most active. Therefore, when frying, it is necessary to control the amount of each pot, so that it can be squeezed with frying to ensure that the hot material is pressed.

This is the reason why peanut oil should be steamed before pressing, for other knowledge of edible oil pressing, if you have any questions, please ask.
