Studies on damage to sunflower seeds: water activity, germination, acidity index and aflatoxin B1 presence.
The significance of fungal contamination during the storage of sunflower seeds has been investigated. Samples were taken during 7 months at 45 day-intervals. Water activity, seed germination, presence of aflatoxin B1 and free fatty acids were monitored. It was demonstrated that water activity increased during storage, germinability decreased, the content of free fatty acid increased and so did the content of aflatoxin B1.
