Corn stem fiber fractionation by acid hydrolysis

Abstract

Fractionation was carried out by hydrolyzing corn stalk powder with 0.3 M HCl. The hydrolysis process was carried out with 3 variations of acid volume with 3 replications in each variation. This hydrolysis will be carried out at a temperature of 100 – 120°C for ± 60 minutes. The glucose level before hydrolysis was 9.7%. The average glucose levels produced after hydrolysis in each volume treatment were 8.56% at a volume of 600 ml, 8.4% at a volume of 650 ml, and 7.92% at a volume of 700 ml.
