Improvement of Sugar Production From Potato Pulp with Microwave Radiation and Ultrasonic Wave Pretreatments. Issue 1 (19th January 2014) - Miao, Wenhua
Abstract Potato pulp was pretreated through the process of microwave and ultrasonic wave before they were hydrolyzed by cellulose. They were pretreated with microwave power of 240 W at microwave time of 7 min and with ultrasonic wave power of 200 W at ultrasonic wave time of 10 min, respectively. The reduction in sugar and glucose content in pretreated specimens under both pretreated conditions were measured by biotransformation method; the experimental results indicated that both the microwave and ultrasonic wave treatment could lead to significant improvement in sugar production, including reducing sugar and glucose, which provided potential strategies for widening practical application of potato pulp in the food industry. Practical Applications Energy and environment problems can be meaningfully addressed by fully using the by‐products of the agricultural products processing industry. And this research is also of practical relevance with regard to the biofuel industry. In this study, use of microwave and ultrasonic wave pretreatment could lead to significant improvement in sugar production, including sugar and glucose reduction, which means improvements in production yield and reductions in production costs. And this also provides potential strategies for widening practical application of potato pulp and some other by‐products of the agricultural products processing industry.
