Titrimetric evaluation of cyanogens in parts of some Nigerian cassava species

Abstract

In this study, Tropical Manihot Selection TMS 30572 fresh cassava samples from Kubwa (in Abuja) and Agbara (in Ogun State) of Nigeria were evaluated for cyanogens using titrimetric method. The variations in the cyanide concentrations from different parts of the plant were significant at p<0.05 and of the order leave> peel> tuber (flesh)> stem. The average cyanide contents, respectively for the Abuja and Agbara samples ranged from 32.85±1.55 ppm to 36.17±11.80 ppm for stems; 50.24±0.18 ppm to 74.38±0.41 ppm for tubers; 74.38±0.41 ppm to 84.96±1.70 ppm for peels and 105.21±0.95 ppm to 118.00±13.70 ppm for leaves. © Asian Network for Scientific Information, 2011.
