Abstract

The study investigates the parametric and kinetic study on the hydrolysis of pineapple peels using hydrochloric acid.The effects of the concentration of hydrochloric acid and temperatures on the reducing sugar concentration of pretreated and unpretreated on the reducing sugar observed. Also, the kinetic constant was determined. Results showed that as the acid concentration increased, the reducing sugar concentration increased for both pretreated and unpretreated sample. Also, as the temperature increased, the reducing sugar concentration decreased for both pretreated and unpretreated samples. The highest reducing sugar concentration for without pretreatment is 4.957 g/L while for with pretreatment is 5.832g/L. it showed in general, there is no significant difference between with and without pretreatment. For the kinetics study, it showed that the hydrolysis of pineapple peels is first order and the kinetic constant is 0.0002 min⁻¹ and 0.012hr⁻¹.
