Effect of drying method and storage conditions on quality and incidence of aflatoxins in dried chillies (Capsicum frutescens) in Zimbabwe

Zimbabwean farmers have to continue producing a good quality product that is free from aflatoxin contamination or is below the maximum acceptable levels of aflatoxin contamination in order to export chilli. Four chilli varieties, African bird’s eye, Baby bird’s eye, Serenade and Bishops crown are available on the local market. Chilli destined for the export market was free from aflatoxin contamination. Chilli on the local market contained AFB1 and AFB2 both at an average of 6ppb. Drying chilli in Marondera using 3 different methods gave a significant difference (P<0.05) in total aflatoxin levels and days needed for drying. Different packaging treatments used did not have a significant effect (P>0.05) on any of the quality parameters measured or on total aflatoxin levels. The combined effect of drying method and packaging material did not have a significant effect on total aflatoxins, ascorbic acid content, pH and moisture content of the dried chilli.
