Soybean oil is a vegetable oil extracted from soybean seeds, commonly found in daily life. It is often light yellow in color and has a unique soybean aroma, containing a rich amount of unsaturated fatty acids such as linoleic acid and oleic acid, which can lower cholesterol and prevent cardiovascular diseases. Its human digestive absorption rate exceeds 98%, making it highly nutritious. Soybean oil comes in a wide variety of packaging sizes. Small sizes of 200-500ml are suitable for sampling or short-term use; common household sizes are typically 1-5L, such as 1.8L and 5L packs, meeting daily cooking needs; commercial catering usually chooses large 10L and 20L桶装 sizes. The main material is high-quality soybeans. The processing techniques are divided into two types: pressing and solvent extraction. Pressing relies on physical force to extract oil, retaining more nutrition and flavor; solvent extraction uses extraction principles, with a higher oil yield. According to national standards, soybean oil is divided into three categories: crude soybean oil, pressed refined soybean oil, and solvent-extracted refined soybean oil.
