Fatty acid and tocopherol contents of several soybean oils.

The oleic acid content of seed oils varied between 21.4% (ATAEM7) and 26.6% (Türksoy). The proportion of linoleic acid of soybean oil ranged from 49.0% (Türksoy) to 53.5% (ATAEM7), while the palmitic acid of oils varied between 9.2% (Adasoy) and 11.2% (Noya). The major tocopherols were ¥-tocopherol, α-tocopherol and δ-tocopherol in all the varieties of soybean oil. As a result, this study showed that the seeds are to be a potential source of valuable oil which might be used for edible and other industrial applications.
