The objective of this research was to investigate the effect of carbon dioxide injection during extrusion process at different melt temperatures 95, 115 and 135°C on physiochemical properties and enzymatic saccharification of extruded corn starch for fermentation substrate preparation. Carbon dioxide gas was injected during extrusion at the flow rate of 500 ml/min and pressure of 3 MPa. For enzymatic saccharification, 0.8% α-amylase enzyme was used at different saccharification periods. After extrusion, physiochemical properties and reducing sugar content The objective of this research was to investigate the effect of carbon dioxide injection during extrusion processat different melt temperatures 95, 115 and 135°C on physiochemical properties and enzymatic saccharification ofextruded corn starch for fermentation substrate preparation.

The data clearly showed that carbon dioxide injection gave significantly increased (p<0.05) reducing sugar content at melt temperatures 115 and 135°C for fermentation substrate preparation. |
