Production Characterization And Optimization Of Starch Based Biodegradable Bioplastic From Waste Potato Peel With The Reinforcement Of False Banana (ensete Ventricosum) Fiber

Recently, environmental pollution from petroleum-based synthetic plastics become the headache of the world. Their greatest problem is that they are not biodegradable. To combat this serious issue producing biodegradable bioplastics is becoming the best solution ever. In this study, potato peel starch (PPS) based bioplastic film was developed. The proximate composition of potato peel was found to be 8.13, 4.89, 10.13, 0.27, 9.52 and 51.16 % by dry weight basis for moisture, ash, crude protein, crude fat, crude fiber and starch content, respectively. PPS contained 18.6, 0.01, 0.53, 0.00 and 27.93 % for moisture, ash, protein, fat and amylose, correspondingly. A bioplastic film was prepared by a method of gelatin casting, in which the effect of 13.33, 23.33 and 33.33 % v/w (HCl or glycerol to PPS ratio) concentration of HCl and glycerol as well as drying temperature (45oC, 55oC and 65oC) was studied. The experiment was designed and optimized by a three-variable, three-level Box–Behnken design using Response Surface Methodology (Design Expert® software version 13.0.1). The ANOVA analysis showed that the model is significant with P
