Research on Aspergillus flavus Toxin-producing in Pu′er Tea Fermentation
摘要
Abstract
For the purpose of studying the Aspergillus flavus growth and toxin production in Pu′er tea fermentation, the Yunnan large-leaves solar-drying green tea was used as the raw material to fermentate by inoculating toxigenic Aspergillus flavus fungus in Pu′er tea. Aflatoxin was tested by LC-MS/MS method at the end of tea samples fermentation. The results showed that during the tea fermentation, Aspergillus flavus growth was observed in the initial fermentation. However, with the extension of Pu′er tea fermentation time, Aspergillus flavus growth were inhibited in the late fermentation, the number decreased gradually, while the end of fermentation, the aflatoxin was not detected in tea samples.关键词
