Chronic toxicity could occur in humans when “gaari” with excess permissible amount of cyanide is consumed which negates food security. This study assessed the levels of cyanide in the “gaari” sold in Sango, Apete, and Bodija markets in Ibadan, Oyo State, Nigeria. Three most popular, locally processed commercial “gaari” named: Oyo (A), Ilora (B) and Egba (C) were obtained from each of the three markets and were pooled for residual cyanide content analysis using titrimetric and picrate test method. pH, swelling capacity, and bulk density were determined using standard methods. The cyanide content level ranged between 2.51 ± 0.003 to 3.72 ± 0.05mg/ kgHCN in Sango market, 2.51 ± 0.003 to 3.67 ± 0.05mgHCN/kg in Apete market and 2.53 ± 0.003 to 3.78 ± 0.05mgHCN/kg in Bodija market. Egba “gaari” had the.. View More»
