Determination Of Cyanide Content In Yellow Root And White Root Cassava Tuber (Manihot esculanta crantz) From National Root Crop Research Institute, Umudike

ABSTRACT

The Cyanide Content of four varieties of Cassava: (Tropical Manihot Selection; TMS 01/1638), (Tropical Manihot Selection; TMS 01/1412), (Tropical Manihot Selection; TMS 419), and (Tropical Manihot Selection; TMS 98/0505), from National Root Crop Research Institute (NRCRI), Umudike were studied using Picrate method. The Cyanide contents were: TMS 01/1638 (0.424) mg/kg, TMS 01/1412 (0.443) mg/kg, TMS 419 (0.557), AND TMS 98/0505 (0.518) mg/kg. The Cyanide content of the Yellow Root Cassava was found to be low compared to the White Root Cassava. The results of the Cyanide Content in the Current study were found to be within the acceptable unit as recommended by WHO.
