摘要
The lipid fraction of Jalisco and Sinaloa chia seeds was analyzed for oil content, fatty acids, squalene and phytosterols. The mean oil content of seeds from these two regions was significantly (p <= 0.05) different, but with a similar composition of alpha-linolenic, linoleic, oleic, palmitic and stearic acids. Total phytosterols in the oil ranged from 7 to 17 g/kg. beta-sitosterol accounted for up to 74% of the total unsaponified fraction. The seeds contained less than 0.5 g/kg of squalene. The oil is an attractive source of omega-3 linolenic acid and phytosterols but a poor source of squalene.
