The results indicated that hydrolysis of DTSM having smaller
particles (less than 0.25 mm) did not significantly affect the protein
extraction ratio. However, when DTSM samples with larger particles
(>0.25 mm) were hydrolyzed, the protein extraction ratio
decreased with increase in particle size and this trend has become
more obvious with the increase in hydrolysis time to 3 and 5 h.
