NUTRITIONAL COMPOSITION AND CYANOGENIC CONTENT OF GARI SAMPLES IN OSUN STATE

NUTRITIONAL COMPOSITION AND CYANOGENIC CONTENT OF GARI SAMPLES IN OSUN STATE

ABSTRACT
Six samples of Cassava product (garri) were collected from different processing centres in Osun state and subjected to proximate and cyanogenic analysis to determine their nutritional composition and safety for human consumption. At the end of the analysis, the results is vary because of climate, weather, and nutrient of the soil. All the samples met the standard recommended by IITA 2005 and FSAN 2004. And thus safe for human consumption.
