How to get oil from crude oil
Whether the pressed oil or extracted oil cannot eat directly, it is called crude oil. For instance, there are impurities contained in crude oil, including raw material, oil pressing process or oil extraction process. Some impurity is harmful to human body health. For example, gossypol in cottonseed oil needs to be removed in order to get edible standard oil.

Test of finished edible oil quality
About quality of edible oil, there has developed a series of indicators, known as the national standard. Various types of oils have corresponding standard, generally containing color, smell, transparency, soap-containing amount, insoluble impurities, acid value, peroxide value, and the residual solvent indicator amount and other projects. The acid value, peroxide value and solvent residue is mandatory targets of national edible oil. All indicator approval oil finally reach edible oil standard.

Finished edible oil can be divided into four classes. For instance, first class edible oil, such as salad oil, no better getting from oil pressing or oil extraction crude oil, should be processed into high quality standard edible oil without color, small and odor. The solvent residual quality should be shown of no indicator.

Finished edible oil can only be processed through alkaline refining, decolorization and deodorization until getting refined edible oil. The finished edible oil after edible oil refining processing equipment has no containing of impurity, national standard approval, and finished product can be eaten directly for cooking.
