According to the research result, it can be seen that the seed oil of yam-bean (Pachyrhizus erosus (L.) Urb.) contains all basic substance layers of lipid: polar lipid (PL), sterol (ST), triacylglycerol (TG), and free fatty acid (FFA). Among them, triacylglycerol occupied the highest content (about %) whereas the figures for polar lipid and free fatty acid were also relatively high. In the studied seed samples, the highest content of linoleic acid achieved around %. There are no published results up to date about the content of fatty acid, tocopherol (with γ-T of mg/kg), sterol (with β-Sitosterol of mg/kg) of yambean seed oil in Viet Nam. |
