In general, the color is yellowish, light green, puce, etc. Refined soya bean oil is yellowish. The soybean oil with deep color have beany flavor, and also its thermostability is poor. When heating, the soybean oil will produce more bubbles. Soybean oil contains more linolenic acid, easily to oxidate and produce “bean smell”.

Soya bean oil is a kind of frequently-using cooking oil which is commonly sais soybean salad oil.

Soybean oil is extracted from the seeds of the soybean seeds through cold pressing or hot pressing. About cold pressing oil, it has a light color and light soybean flavor. As for hot pressing oil, the high-temperature processing has lead to high oil yield. Whereas the color is deeper with the thick bean smell. According to the process, it contains crude soybean oil, filtered soybean oil, refined soybean oil. Crude soybean oil is tawny, whereas most of the refined soybean oil is yellowish with large stickiness. If soybean oil is exposed to air for a long time, the surface of soybean oil will appear unstable film. Soybean oil nutrition value is higher than other oil, many people in China like it.

Soybean oil contains 7-10% palmitic acid, 22-30% oleic acid, 2-5% stearic acid, 50-60% linoleic acid, 1-3% arachidic acid, 5-9% linolenic acid.

In terms of nutrition value

The composition of soybean oil is better, it is rich in linoleic acid, which can reduce the content of serum cholesterol obviously, prevent cardiovascular disease.
