Preparation and characterization of bio-nanocomposite based on potato starch/nano-clay/mint essence

In this research casting method was used to prepare potato starch based bio-nanocomposite films with nanoclay and mint essence as the reinforcing materials. The composition included potato starch with 40% (w/w of total solid ) of a mixture of the sorbitol/glycerol (weight ratio of 3 to 1as plasticizer) with nanoclay (3% wt.) and mint essence with different concentrations (10-30% vol.). Results showed that by increasing the concentration of mint essence, Physical properties of films were improved. WVP increased (P
