FABRICATION AND CHARACTERIZATION OF JACK FRUIT-SEED STARCHBASED BIOPLASTIC

Abstract

In this article, the authors synthesized and analyzed research papers that dealt with the fabrication and characterization of starch-based bioplastics. As the first step, some fruit-seeds were investigated for starch supply ability. Results revealed that compared to durian-seed and avocado-seed, jack fruit-seed had the highest starch ratio. Furthermore, it was not only easy to collect but also cheap or even free of charge. Afterward, a starch-based bioplastic fabrication procedure was synthesized from the literature review. From preliminary tests, plasticizers were sufficiently selected, including H2O, glycerol, natri bicarbonate and acid citric. Four kinds of bioplastic utilizing different combinations of these plasticizers were then fabricated to study the effect of them as well as characterize the properties of the corresponding bioplastics. After that, based on ASTM D412 type A standard, a mold and a cutting tool for dog-bone sample making were designed and fabricated. Using these dog-bone samples, tensile results showed that the hardness of the fabricated bioplastic was positively proportional to the ratio of the starch. It is worth noting that the
plasticizing was not able to completely occur with too much percentage of starch...
