At the 20th International Biology Congress, Rize Commodity Exchange and Rize University jointly presented black tea, which does not produce aflatoxin, which is the cause of air humidity, and that there is no harm to human health. This study was supported by the Tea Research Institute.

Rize University Instructor Assoc. Dr. Şengül Alpay Karaoğlu stated that they are investigating the isolation of mold fungi in black tea and whether or not they have aflatoxin producing species in them. "In our research, it is observed that there are no molds or bacteria in the oven leaves in Turkish tea, it did not produce aflatoxin which could be harmful. In our research, we have found that aflatoxin is not harmful to health even in tea containing up to 70% moisture. "

Hacer TAŞKIRAN GENC, a biologist at the Department of Microbiological Analysis Laboratory of the Private Food Control Laboratory of the Rize Commodity Exchange, who previously reported that such a study was not conducted for the Turkish Ceylon, said: "There is no scientific data on the mold formation and associated aflatoxin presence in the black tea produced in our country. In this study, it is aimed to eliminate this deficiency. More green tea and black tea needs to be done more scientific research, "he said.

Taşkıran said that they examined 122 samples and found that none of them had aflatoxin. "Black tea, which is the most consumed drink in the world, has less mold compared to other dry food because it is baked, and these molds are species that do not cause disease and are mixed in atmosphere during storage and packaging stages "he said.
