Abstract

Two bulk samples of groundnuts naturally contaminated with aflatoxigenic Aspergillus flavus were kept under 3 different storage conditions and environmental temp., relative humidity, water activity, free fatty acids, aflatoxin concn and fungal flora were determined at monthly intervals. The samples stored from fall to winter showed no significant accumulation of aflatoxin. During summer to fall, groundnut samples contained detectable levels of aflatoxins, but variation in levels over 6 months storage was small. In an experimental study, aflatoxins were found after incubation of raw shelled groundnuts inoculated with A. parasiticus ATCC 15517 at 100% RH and 25°C for 2 months. However, growth of aflatoxigenic fungi and aflatoxin production were not observed during storage for the same period at RH ≤79% at 25°C
