Production process of peanut oil

Production process of peanut oil

Peanut oil has become a common healthy oil in family kitchens with its high-quality nutrients and unique flavor. It is mainly extracted from high-quality peanuts by physical or chemical methods.

The following are the main steps of the production process:

1. Raw material selectionSelect

high-quality peanuts with full grains and no mildew to ensure the quality and pure taste of the oil.

2. Cleaning and shelling

Remove impurities such as mud and sand, and remove the shells to leave intact peanut kernels.

3. Pressing：

Cold pressing ：crushed into granules and then directly pressed to retain more nutrients and natural aroma.

Hot pressing: peanut kernels are moderately roasted to stimulate the aroma of peanuts, and then crushed into granules to facilitate subsequent oil extraction, with a high oil yield and rich oil aroma.

4. Filtration：

The pressed crude oil is filtered to remove impurities to obtain clear and bright peanut oil.

5. Refining：

The crude oil undergoes refining processes such as degumming, deacidification, decolorization, and deodorization to further improve the purity of the oil (remove impurities invisible to the naked eye), reduce the acid value to increase the shelf life, remove pigments, make the oil clearer and more transparent, remove odors and improve the taste, making it more suitable for cooking.
