Reducing Sugar Production from Durian Peel by Hydrochloric Acid Hydrolysis

Abstract— Agricultural waste is mainly composed of cellulose and hemicelluloses which can be converted to sugars. The inexpensive reducing sugar from durian peel was obtained by hydrolysis with HCl concentration at 0.5-2.0% (v/v). The hydrolysis range of time was for 15-60 min when the mixture was autoclaved at 121 °C. The result showed that acid hydrolysis efficiency (AHE) highest to 80.99% at condition is 2.0% concentration for 15 min. Reducing sugar highest to 56.07 g/litre at condition is 2.0% concentration for 45 min. Total sugar highest to 59.83 g/litre at condition is 2.0% concentration for 45 min, which was not significant (p < 0.05) with condition 2.0% concentration for 30 min and 1.5 % concentration for 45 and 60 min. The increase in concentration increased AHE, reducing sugar and total sugar. The hydrolysis time had no effect on AHE, reducing sugar and total sugar. The maximum reducing sugars of each concentration were at hydrolysis time 45 min .The hydrolysated were analysis by HPLC, the results revealed that the principle of sugar were glucose, fructose and xylose.
