Physico-chemical characteristics and aflatoxins production of Atractylodis Rhizoma to different storage temperatures and humidities

Abstract This study aimed to investigate the characteristics, moisture contents, chemical fingerprints changes and aflatoxins accumulation of Atractylodis rhizoma during storage, further to determine the optimum temperature and relative humidity conditions. Based on the suitable temperature (20–40 °...
