Abstract


Nigeria is the highest producers of cassava roots all over the world. Several staple products are generated from these crops but the peels which carry one quarter of the products are discarded as waste on dunghills. This often constitutes an environmental problem to the community. One of the ways to curb environmental pollution and its associated diseases is to reduce the incidence and accumulation of generated waste in the community. This is the focus of the study.

In this work, cassava waste peels were gathered from four different cassava processing centers in Ogbomoso . It was fermented at solid state for 72 hours at temperatures of 23, 30 and 37°C using isolated fungal strain (Aspergillus niger) to produce citric acid. The quantity of citric produced was assayed using pyridine­ anhydride method.

It was found that the amount of citric acid produced increased with increased in temperature from 23-30 oC but decreased at 37 oC. For instant sample A has citric acid production of 42, 143 and 84 g/kg sample at 23, 30 and 37 oC respectively.
