Production of ethanol from cocoa pod hydrolysate

Production of ethanol from cocoa pod hydrolysate

Cocoa pod (Theobroma cacao L.) hydrolysate was hydrolyzed into glucose using hydrochloric, sulphuric and nitric acids, respectively. The concentration of each acid was set at 0.25 M, 0.50 M, 0.75 M, 1.00 M and 1.25 M. They were treated under two different temperatures and time at 75˚C and 90˚C for 2...
