Abstract

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.

摘要

对向日葵种子储存期间真菌污染的重要性进行了研究。在7个月内每隔45天采集一次样本。监测了水分活度、种子发芽率、黄曲霉毒素B1的存在情况以及游离脂肪酸含量。结果表明，储存期间水分活度增加，发芽能力下降，游离脂肪酸含量增加，黄曲霉毒素B1含量也增加。
