Abstract

The aim of this study is to investigate the density and water affinity properties of thermoplastic cassava starch matrix containing palm wax (TPCS/PW). The samples were prepared via hot pressing by varying the ratios of palm wax (2.5, 5, 10, and 15 wt%) with the presence of glycerol as a plasticizer. The resulting blend was thermo-pressed at 150 °C to produced plates having 3 mm thickness. The prepared plates were characterized for the density and water affinity properties. Results showed that incorporating starch-based thermoplastics with palm wax has remarkably reduced the density of the samples from 1.45 g/cm3 to 1.22 g/cm3 meanwhile the moisture content was also decreased gradually following increasing amount of palm wax in thermoplastic cassava starch matrix from 12.01% to 8.28% respectively. Besides, the water absorption of the samples improved water resistance when increasing wax addition from 40.40 ± 1.11 to 27.86 ± 0.87%. Overall, this study shows that the incorporation of palm wax into thermoplastic cassava starch has improved the functional properties of this green material especially on moisture behavior and has the potential to be used as biodegradable materials. Through the targeted modification of starch, novel products are consistently being created, which are increasingly utilised across a diverse range of industrial applications. Given the significant increase in interests and the wide range of materials currently available, it is evident that there are limitless opportunities rather than limitations.
