Influence of relative humidity on seed mycoflora in relation to mycotoxin production and seed health of black pepper.

The effect of relative humidity (RH) on the seed mycoflora of black pepper (Piper nigrum) in relation to mycotoxin production and seed health was investigated. The seed mycoflora underwent significant change both qualitatively and quantitatively with regard to humidity and time of storage. Species of Aspergillus, Penicillium and Fusarium could be recorded at different humidity levels throughout the year. In contrast, Verticillium albo-atrum and species of Cladosporium disappeared by the end of storage irrespective of the percentage of humidity. Some of the fungi associated with black pepper were mycotoxigenic. The levels of total phenols, proteins and free fatty acids increased with the length of storage, while the reducing sugar and starch contents decreased. The mycoflora was quantitatively rich on seeds stored at 100% RH.
