ABSTRACT

Pomegranate (Punica granatum) is polysaccharide source that can be converted to reducing sugars. Pomegranate was hydrolyzed using sulphuric acid at temperature 75˚C. It was observed that the degradation has significant effect with respect by varying time (60, 90 minutes) and concentration of (Sulphuric acid and Hydrochloric acid). In turn sugar yield is around 40-50%, each which is estimated by Bertrand’s, Benedict’s, and Lane-Eynon methods.

Keywords: Degradation, hydrolysis, pomegranate peels, reducing sugar, estimation.
