Does peanut oil solidify more easily than blended oil? So peanut oil is expensive but really healthy?

1. First of all, it should be understood that peanut oil contains 13%-20% saturated fatty acids in addition to unsaturated fatty acids unique to plants, and one of the characteristics of saturated fatty acids is that it will solidify at low temperature, so as long as the temperature is low enough, even high-quality peanut oil will solidify.

2. But the solidification temperatures of adulterated peanut oil and pure peanut oil are different. This method can be used to judge whether peanut oil is pure or not.

3. Generally, when the room temperature is 3- 10 degrees, a small amount of pure peanut oil will solidify and appear white floc. When the temperature is below 3 degrees, peanut oil will completely solidify and cannot flow; If it is adulterated peanut oil, it will solidify or have milky white flocs above 10, usually mixed with cheap lard or palm oil.

Peanut oil will go through a filtration process after being pressed. If the filtration is not thorough in this process, there are a lot of peanut residues in the oil, which will not affect the quality of the oil.

The composition of peanut oil is not single, including monounsaturated fatty acids, polyunsaturated fatty acids and saturated fatty acids, and its freezing point is not a stable value. At low temperature, some oil will solidify first, and white precipitate or floc will appear, which will not affect the quality of oil.

Oxidation and deterioration of oil will also produce precipitation, commonly known as "oil foot", which is a black precipitation substance. This odorless oil is not recommended, and the chemical composition of the oil has changed, and even some toxins have been produced, which is harmful to the body.

It may solidify.

Because the production cost of adding palm oil to blended oil will be lower, many manufacturers add palm oil to blended oil produced in summer. However, the freezing point of palm oil is relatively high, and it will condense below 20 degrees, especially in winter, which is also the reason why blended oil is easy to condense.

Peanut oil is actually rich in a variety of fatty acids, especially saturated fatty acids, so eating peanut oil can not only be digested by the human body, but also help us strengthen our physique and prevent diseases.

When eating peanut oil, we can find that peanut oil contains a lot of vitamin E and resveratrol, and at the same time, wheat germ phenol, choline, zinc and other nutrients are particularly rich, which are very much needed by our human body, and these substances can have positive significance for our human body operation. Choline in peanut oil is also rich, which can improve memory, promote skin health and prevent cardiovascular diseases.
