Soybean Oil Characterization
The chemical properties of the purified and unpurified soybean oils are
shown in Table 1. As can be seen, the purification process did not
affect the composition of soybean oil fatty acids. The stripped soybean
oil contained an insignificant amount of hydroperoxides, phenolic
compounds, and tocopherols, showing the minor components’ efficient
removal that may interfere with the antioxidant compounds.
