About the grade of edible oil, each country has its own rule. This article mainly introduce the Chinese national standards of the edible oil grade, which is similar with other countries'. If you are interested in it, please continue reading.
According to Chinese national standards, edible oil is generally divided into four grades, level 1 to level 4. The grade 1 edible oil is with the highest refining process, also is qualified to be sold in supermarket.
The following table is the specification parameters of the final edible oil product:

The refining degree of Grade First and Second edible oil is relatively high and the quality is better. Through the edible oil refining process of degumming, deacidification, decolorization and deodorization, the final edible oil has the characteristics of tasteless, light color, high smoke point, less cooking oil smoke, and difficult to solidify at low temperature. After refining, the contents of harmful components in the Grade First and Second edible oil are low, and the storage time will become longer.
The refining degree of Grade Three and Grade Four edible oil is relatively low. The crude oil is simply processed through degumming, deacidification and other procedures. The colour and lustre of the final edible oil is deeper, the smoke point is inferior, and the oil smoke is thick in cooking process. The content of impurities in the Grade Third and Fourth edible oil is higher, but it is edible.
