| description |
Recently, starch-based bioplastics have been proposed to curb the problem caused by
conventional plastics. Yet, current bioplastics aremade from food sources which cause
competition with food industries. Hence, we have produced bioplastics using rotten
starch-based material to tackle this problem. In this study, a comprehensive investigation
has been carried out on the preparation of bioplastics extracted from fresh
jicama (FJ) and rotten jicama (RJ). Specifically, glycerol as the plasticizer and starch contentswere
varied to obtain bioplasticwith the optimum properties via tensile, chemical
and thermal characterizations. The results have confirmed that both FJ and RJ starch
bioplastics possessed similar characteristics in terms of physical appearance, transparency
and chemical functionalities. Moreover, the tensile and thermal properties of
RJ and FJ bioplastics fall within the range specification for packaging applications. FJ
bioplastic has maximum stress of 0.43 MPa and maximum strain of 50 MPa at an optimized
concentration (St31%_gly6.75) which tells that they formed stronger and higher
flexibility than RJ bioplastics. Importantly, the RJ bioplastics have a faster biodegradation
rate compared to FJ bioplastics. In conclusion, bioplastics from rotten starch have
properties as good as FJ and served as a feasible platform for the development of bioplastics
from rotten sources. |
