Waste pineapple skin (WPS) has been hydrolyzed into reducing sugar (RS) using Amberlyst 15 catalyst. The effects of the application of infrared radiation on the intensification of hydrolysis of WPS have been evaluated. The Taguchi orthogonal design determined optimal values of process factors, viz., 70 °C reactor temperature, 30 min batch time, water to WPS ratio (w/w) of 35, and 2 wt% catalyst concentration, corresponding to maximum 86.78% RS yield employing an infrared radiated batch reactor (IRRBR). Remarkably, the RS yield in IRRBR was significantly greater than that obtained (45.62%) using a traditional batch reactor (TBR) at the derived optimal conditions. |
