We then moved our attention towards valorizing the second-most abundant polysaccharide appearing in nature, the starch biomass. Rice grains and potato flour were tested which contains 100% amylose and amylopectin . While these feedstock are typically considered edible resources, there may be circumstances where it is necessary to classify them as non-food, especially if they are part of food waste. Thus, yields of 9 wt% and 8 wt% were obtained from rice grains and potato flour, respectively, after 24 hours (Table ). Extending the reaction time to 72 hours improved the GVL yields to 16 wt% and 20 wt%, respectively. These results indicate that the catalytic system is very efficient in hydrolyzing not only the α(1-4) glycosidic linkages, but also the α(1-6) linkages between glucose units of amylopectin, which is the major component of starch.
