Development and optimization of biodegradable films based on achira flour

AbstractThe influence of glycerol concentration (Cg), process temperature (Tp), drying temperature (Ts), and relative humidity (RH) on the properties of achira flour films was initially assessed. The optimized process conditions were Cg of 17g glycerol/100g flour, Tp of 90°C, Ts of 44.8°C, and RH of 36.4%. The films produced under these conditions displayed high mechanical strength (7.0MPa), low solubility (38.3%), and satisfactory elongation values (14.6%). This study showed that achira flour is a promising source for the development of biodegradable films with good mechanical properties, low water vapor permeability, and solubility compared to films based on other tubers
