Abstract

|
|
Raw adlay powder (RAP) and processed adlay powder (PAP) were prepared and the changes of fatty acid compositions of lipids in RAP and YAP during storage at 5℃ and 35℃ for six months were studied. The major fatty acids found in the adlay lipids were oleic acid (28-45%), linoleic acid (38-50%) and palmitic acid (14-18%). Throughout the storage period, the concentrations of linoleic acid were decreased in samples stored at 35℃ , but those of oleic acid and palmitic acid were relatively increased according to the oxidation proceeded. However, the concentrations of these fatty acids were hardly changed in samples stored at 5℃. These changes were especially more notable in the lipids from RAP than those from PAP during storage. Little difference in fatty acid composition was noted between neutral lipids and triglycerides in the samples.
