CHANGES IN SEED OIL PROFILE FOR NIGER SEEDS (GUIZOTIA ABYSSINICA) UPON STORAGE AT DIFFERENT CONDITIONS

Jaya Singh Bisen

Abstract


Guizotia abyssinica is a marginal oilseed crop, closely related to sunower seeds. The changes in oil prole as a function of time were recorded
using Gas Chromatography. The fatty acid prole were measured, and compared with seeds stored for six years in ambient conditions, as well as
seeds stored under cold storage conditions with that of freshly harvested seeds. The results showed that the fatty acid prole under ambient storage
conditions changed as a function of storage time. The percentage of oleic acid, linoleic acid and linolinic acid decreased under ambient conditions,
while percentage of erucic acid increased with increase in storage time under ambient conditions.
