The effect of solid loading, acid concentration, and temperature were studied in the hydrolysis of saba (Musa paradisiaca) peels. Solid loadings of 6.67%, 10% and 20% (w/v), sulfuric acid concentration s of 1%, 2.5% and 5% (v/v), and temperature of 32°C( room temperature), 50°C and 70°C were used in the hydrolysis set-ups. Results showed that the 20% solid loading formed very viscous mixture that no hydrolyzate was obtained for the reducing sugar analysis. Solids loadings of 6.67% and 10% (w/v) maximum reducing sugar yields of 8.1% and 9.0%, respectively. The mean reducing sugar yields for the two solid loadings were not significantly different from each other based on statistical analysis using ANOVA at α=0.05. Since the solid loading of 6.67% (w/v) was the most economical, it was the solid loading used for the determination of the effects acid concentration and temperature. Increasing the acid concentration from 1% to 5% (v/v) sulfuric acid at a constant temperature of 70°C had no significant effect in the hydrolysis of banana peels based on the reducing sugar yields obtained. This was shown by the results obtained in a 9-hr reaction. The hydrolysis set-up with 1% H₂SO₄ obtained maximum reducing sugar yield of 5.9% after 6hrs; that with 2.5% H₂SO₄ gave4.6%maximum reducing sugar yield after 3 hrs; and that with 5% H₂SO₄ gave 4.8% maximum reducing sugar yield after 2 hrs. These results were obtained in the 9-hr reaction time. For the shorter reaction time of 2 hrs, the highest reducing sugar obtained at 1%, 2.5% H₂SO₄ were 10.8%, 13.1% and 13.4% reducing sugar, respectively. Increasing the temperature also increased the reducing sugar yield of the hydrolysis of banana peels. The highest reducing sugar concentration and yield, which were 9.307g/L and 18.6% respectively. occurred at 70°C . The highest reducing sugar yields obtained for the other temperatures were 6.6% for 32°C and 88% for 50°C .
