A BSTRACT
The effect of washing on the cyanide and starch content of light was investigated. The cassava roots (TMS 30572) were cooked for 2o minutes shredded, pre-dried and washed. Cyanide and starch contents of the samples were determined. Results showed that boiling induced the cyanide content of the sample to 18.l3mg/l00g while washing led to further detoxification to 9.2lmg/l00g. Washing also reduced the starch content to 0.97%. cheese final cyanide and starch values indicate that ighu is safe for human consumption, and relevant in specialized feeding of weight watchers and humans needing low carbohydrate foods.
