Between non-transgenic soybean oil and transgenic soybean oil, differences in stearic acid, r-linolenic acid, erucic acid and nervonic acid levels are not significant, the difference in palmitic acid level is significant, and differences in oleic acid, linoleic acid and linolenic acid levels are extremely significant. As a whole, there are significant differences in nutritional ingredients between transgenic and non-transgenic soybean oils. Types of nutritional ingredients are same, but quantities of nutritional ingredients are different.
