This research explores the potential of starch from agro-industrial waste in bioplastic films, finding key physicochemical properties supporting sustainability.
Key Points
To biochemically characterize starch from cassava peels and false yam tubers for bioplastic film applications.
Sample preparation from Manihot esculenta peels and Icacina trichantha tubers
Physicochemical analysis including solubility and swelling power
Fourier Transformed Infrared Spectroscopy (FT-IR) for functional groups
Gas Chromatography-Mass Spectrometry (GC-MS) for bioactive compounds
Scanning electron microscopy to analyze morphological structures
Cassava peel starch showed higher solubility (3.97%) and swelling power (6.38g/g) than false yam starch.
Cassava starch had more amylose (22.90%) while false yam had higher amylopectin content (82.98%).
Oleic acid was the most abundant bioactive compound in cassava peels (22.25%), whereas cis-13-Octadecenoic acid was dominant in false yam starch.
