Bentonite clay reinforced with plantain starch-based edible film: production and characterization: article / Muhammd Nazran Mohamad Faiz and Fariza Hamidon

Edible film is a thin layer that lines a decent food consumed, and can be degraded by nature. The use of starch as the main ingredient in making plastic has great potential. To obtain edible film, starch is added with glycerol plasticizer, so that the plastic is more flexible and elastic. The starch used was banana starch, which has high hydrophilicity, therefore making it less desirable than synthetic polymers when used as a film. The purpose of this experiment is to produce, evaluate and characterize bentonite clay reinforced with banana Starch-based Edible Film. The edible films were made using banana starch, bentonite clay, and glycerol. Concentrations of bentonite clay were 30%, 10%, 20% and 0%.The edible film were obtained in the form of thin sheets that has been tested for mechanical properties such as tensile strength, elongation at break, and elasticity. Results indicated that the increase of bentonite concentration increase the film solubility. However, the bentonite makes the film tensile strength and elongation decrease.
