ABSTRACT
The fresh cassava were sources from Idodo in Nkanu Local Government of Enugu state. The weight of the cassava tuber were taken to be 31.50kg. After peeling and washing, it was divided into two equal parts which was 21.13kg for production of sample A and sample B respectively (edible and textile starch) which weighed 13.1kg.
During this process, the temperature were obtained at 700c (617.4R). And the other properties of the cassava samples were carried out, such as moisture content of the fresh cassava 59.82% (Sample A), Textile starch 52.02% (Sample B) and edible starch (Sample C). the average mean percent of ash content of Sample A, edible starch was 2.6% while that of (Sample B, fresh crush cassava was 2.1%.
Also determination of cyanide content of fresh cassava 14.13ml. Textile 5.0ml and edible starch 4.48ml.
