Why should sesame oil be squeezed to eat? What is the reason why the oil bubbles when it is hot in the back?

Fried things bubble for two reasons. One is that linseed oil has a low degree of refining after pressing (including filtration, dehydration, impurity removal, dewaxing, etc.). ) and contains a lot of impurities, which will produce foam when frying things. Self-squeezed oil produced by small workshops generally has this problem, and the other is related to fried ingredients.

In order to avoid foaming when frying things, you can choose edible oil produced by regular manufacturers when buying oil. The oil is clear and transparent without precipitation. Generally, fried things do not foam. It can also be selected according to the grade of edible oil. The primary and secondary refining degree is high, the impurities are few, and foaming is not easy. The third and fourth grade refining degree is low, there are many impurities, and it is easy to foam.

The oil yield is extremely low and the cost is high, so the price is not low in the market.
