For grounded (size reduced) wet and dry samples (Samples 3
and 4), the sugar yield increased significantly to 59.32 mg sugar/
g dry matter and 155.13 mg sugar/g dry matter compared to untreated
sample, respectively. The increasing yield of sugar by
130% in Sample 3 has shown that size reduction has successfully
overcome the effect of high moisture content as exhibited in
hydrolysis of Sample 1. Other parallel studies also share the same
findings where improvement on the hydrolysis outcome was contributed
by substrate’s size reduction (Dasari and Berson, 2007;
Yeh et al., 2010). Production of sugar from dried samples (Sample
2 and 4) are also different when particle size of the samples was
varied where higher sugar is obtained when particle size is reduced.
Size reduction has enhanced the hydrolysis process because
the surface area of samples was increased and thus improved acid
penetration into the samples (Sun and Cheng, 2002).
