2.2. Proximate analysis
Some biochemical parameters such as starch content,
fibre
content, protein content and total carbohydrate of the cellulosic
cassava waste was determined. The protein content was deter-
mined using Bradford reagent [18]. Protein standards were used to
get a plot and the quantity of the protein in the sample was
extrapolated from the graph. The
fibre content was determined by
digesting the waste sample with two different acids (0.5 M HCl and
0.5 M H2SO4) and heated for four hours. After that the residual
fibrous material was washed,
filtered and dried. The
fibre content
was then calculated. The starch content was determined by
treatment with a-amylase which selectively digested the starch
and left the insoluble
fibre. The quantity was obtained by
