In order to examine the effect of storage conditions on lipid and minor elements compositions of sesame seed, the changes in general characteristics and fractionation pattern o the lipid, and such minor elements as sesamol, sesamolin and sesamin were analyzed during the storage of sesame seeds for 4, 9, and 15 months at the four different storage conditions, that is, storage under light with linen pouch(LA), storage in dark with linen pouch(DA), storage under light with polyethylene pouch(LS) and storage in dark with poly ethylene pouch(DS). The acid value were increased significantly during the storage for 4 to 9 months then continued same acid value with prolonged storage until 15 months, but iodine value were increased continuously until 15 months in all the storage conditions, and the increasing tendency of the value at LA and DA was higher than that at LS and DS. Steryl ester was increased in the LA but decreased in DS with prolonged storage until 15 months. Diglyceride was increased during the storage in alt the storage conditions and increasing tendency in LA was higher than that in DS and LS. The free fatty acid contents were significantly increased until g months of storage, then similar value was continued with prolonged storage. Phospholipid was decreased with prolonged storage until 15 months and decreasing tendency in DA and LA was sharper than that in LS and DS. The content of free sesamol was ranged from 0.0021 to 0. 0058% of total lipid. Free sesamol was increased but bound sesamol was decreased during the storage for 15 months in all the storage conditions. Sesamolin was ranged from 0.11 to 0.19% of total lipid and decreasing tendency during the storage was similar to free sesamol.
