acid hydrolysis, cassava peels, cellulose, glucose concentration, xylose concentration, saeman model, two- fraction model.



The aim of this work is to study the hydrolysis process of cassava peel using phosphoric acid. The substrate was characterised using proximate analysis and result obtained showed that cassava peel has high hemicellulose content. The effect of process variables; acid concentration (2.5wt%, 5wt%, 7.5wt% and 10wt %) and time variation on glucose and xylose yield were studied. The maximum glucose was obtained as 2.218mg/ml at the following conditions: 7.5wt%, 1mins and 121˚C while the maximum xylose was obtained as 33mg/ml under the following conditions; 10wt%, 3mins and 121˚C. The Saeman’s model and two-fraction were used to fit the experimental data for glucose and xylose yield and two-fraction model gave the best fit for both. In conclusion cassava peel as shown by the results obtained can be used for the production of glucose and xylose.
