ABSTRACT

Growth and aflatoxin production by A. parasiticus (NRRL 2999) on autoclaved whole, ground and also surface sterilized black pepper, cardamom, red pepper, dry ginger and turmeric were studied. Cardamom did not support detectable fungal growth or aflatoxin production. Black pepper and turmeric appeared to be poor sub-strates as they supported comparatively less fungal growth and afla-toxin production. Red pepper and ginger were found to be better substrates for fungal growth as well as for aflatoxin production. Ether and chloroform extracts of cardamom and turmeric inhibited aflatoxin production almost completely. The inhibitory activity of cardamom oil and curcumin indicated that they might be the active principles.
