Abstract
This study was driven by the stringent environmental legislation concerning the consumption and utilization of eco-friendly materials. Within this context, this paper aimed to examine the characteristics of starch and fibres from the Dioscorea hispida tuber plant to explore their potential as renewable materials. The extraction of the Dioscorea hispida starch and Dioscorea hispida fibres was carried out and the chemical composition, physical, thermal, morphological properties, and crystallinity were studied. The chemical composition investigations revealed that the Dioscorea hispida starch (DHS) has a low moisture t (9.45%) and starch content (37.62%) compared to cassava, corn, sugar palm, and arrowroot starches. Meanwhile, the Dioscorea hispida fibres (DHF) are significantly low in hemicellulose (4.36%), cellulose (5.63%), and lignin (2.79%) compared to cassava, corn hull and sugar palm. In this investigation the chemical, physical, morphological and thermal properties of the Dioscorea hispida fibre and Dioscorea hispida starch were examined by chemical composition investigation, scanning electron microscopy (SEM), particle size distribution, thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), and Fourier transform infrared (FTIR), respectively. It was found that Dioscorea hispida waste is promising alternative biomass and sustainable material with excellent potential as a renewable filler material for food packaging applications.
Highlights
Non-renewable materials have caused critical environmental issues in many countries in the world regarding waste disposal [1,2,3]
The extraction of Dioscorea hispida starch and fibre from the Dioscorea hispida tuber was conducted with a number of processes (Figure 1)
There were notable differences observed between the starch samples with regards to the ash, crude fat, crude protein, and starch amounts
Summary
Non-renewable materials have caused critical environmental issues in many countries in the world regarding waste disposal [1,2,3] This problem is overwhelming for countries with limited landfill resources. The production rate of plastic wastes is very much exceeding the plastic degradation rate, presenting an ecosystem imbalance This phenomenon could cause waterborne illnesses resulting from water pollution as plastic waste leachate leaks into water supply areas, e.g., artificial and natural lakes, and impoundment developed from a dam or water storage [6,7]. The word “bioplastics” arises from the need to build new sustainable systems without renouncing some essential physicochemical characteristics [8,9,10] This situation has initiated researchers to find alternative materials originating from biofibres and biopolymers [11,12,13,14]
