The cyanide Levels in two cassava varieties and some derived products was investigated. The study was conducted on fresh tubers by, sampling in three longitudinal positions (1/4: ½: ¾) and four radials (A, B, C and D). In addition the sampling of derived products was carried out by product types (chip dried, Garri and flour). Cyanide Contents were determined. Results showed that whatever the variety considered, there was no significant difference between the total HCN content in cassava slices (1/4; ½ ; ¾ ). Similarly, results from different layers did not highlight radial variability of the total HCN content. The variable cyanide content (MgHCN/kg fresh material) in cassava varieties showed:104.3 ±3.9;171.6±5.4 for Kombo and Nwangbisi respectively. The detoxification processes (gari and flour) indicated a reduction rate in excess of 80% and may be effective to reduce cyanide content in cassava root down to a tolerable level (< 50mgh/kg).

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.1 INTRODUCTIONCassava (Manihot esculenta) is an extensively cultivated tuber crop and a staple food for millions of people in the tropical regions of Africa, Latin America and Asia. Globally, in terms of annual production, it is the fifth most important food crop after maize, rice, wheat and potato. Despite all the usefulness of cassava, its use as a food source is limited by its perishability, its low protein content and its potential toxicity. Cassava contains two cyanog ...
