| description | This work presents the kinetics of natural detoxification of hydrogen cyanide contained in retted cassava roots. Retting is traditional fermentation of cassava, performed to soften the roots. During retting, cyanide diffuses into water used for the retting. The fresh cassava roots (bitter and sweet varieties) used for this experiment were separately retted at ambient 0 temperature of 30 C. The cyanide content and pH were monitored daily. From the analysis of the experimental results, a first order consecutive rate equation is an adequate tool for explaining the mechanism of HCN reduction (or decay) in retted cassava roots. The detoxification constants for the bound cyanide in the bitter and sweet cassava roots were 0.378/day and 0.438/day respectively, while that of the free hydrogen cyanide were 0.63/day and 0.74/day for the bitter and sweet varieties respectively. Cassava tubers from different species cannot be fermented with the same retting condition unless they have same or close functional properties.
