How is peanut oil extracted?

Peanut oil is made from peanuts and is squeezed out through processes such as screening, grinding, steaming, stacking, and pressing. The pressing is further divided into the first pressing, crushing and pressing, and the second pressing. The final filtered peanut oil is edible, and the remaining filter residue can be mixed into the green dough for repeated pressing.

Peanut oil is an edible oil that is light yellow and transparent in color, clear in color, and fragrant in smell. It contains more than 80% unsaturated fatty acids and 19.9% ​​saturated fatty acids. It also contains sterols, wheat germ phenol, phospholipids, vitamins, choline and other ingredients.

Pure peanut oil has high density, thick oil quality, and dark yellow color. It will solidify and not flow when the temperature is below 3°C. If it is mixed with lard or palm oil, the oil quality will be thin and light yellow. It will start to solidify and not flow when the temperature is around 10°C.

When purchasing peanut oil, it is recommended to buy branded cooking oil produced by regular manufacturers, and do not buy bulk oil, because some peanut oil may be squeezed from moldy peanuts and contain toxic substances, which can easily affect the human body.

How to choose peanut oil

1. Identify the “original species”

The selection method of peanut oil is also very particular. Only when we master the correct method of selecting peanut oil can we buy peanut oil of better quality. First of all, when buying peanut oil, we should check the non-GMO label of the raw material on the outer packaging of peanut oil products. High-quality peanut oil has a great relationship with the quality of the raw material itself, and the quality of the raw material directly depends on the original species. Natural high-quality, non-GMO peanut original species can ensure the high quality of peanut oil raw materials, thereby ensuring the safety of peanut oil products.

2. Smell its “original fragrance”

When buying peanut oil, you can also judge the quality of peanut oil by smelling it. Generally, high-quality peanut oil tastes very good. After opening the bottle cap of pure peanut oil, you can smell the mellow and rich natural peanut aroma. This feature also depends on the physical pressing process. Peanut oil produced by pure physical pressing process can retain the natural original aroma of the raw materials in the oil, while the chemical leaching process destroys the active nutrition and aroma of the oil.
