The films were produced by the casting method (Pelissari et al., 2013) using the optimal process conditions established in pre-tests performed in this same study with films of ripe banana peel flour. The process consisted of drying a film-forming suspension that had been applied onto a support. The procedure involved the homogenization by mechanical stirring, during different heating times (30–60min), of aqueous solutions of 4% (w/v) banana peel flour, added with varying concentrations of cornstarch (33.3–66.6g of starch/100g of flour) at a temperature of 90°C. Glycerol (19g of glycerol/100g of flour) was addedatthispoint,andthesolutionwasmaintainedatthistemperature during the study times (30–60min). The solution was filtered through gauze pad (Cicatrisan®) to remove the remaining particles from the solution. Then, 50mL of the final solution was poured into polystyrene plates 15cm in diameter and dehydrated in a ventilated oven (FANEM, 320-SE, Brazil) at 40°C for 48h. The films were conditioned in desiccators at relative humidity (RH) 58%, at 23 ± 2°C, for 48h, before being characterized in terms of the physical, barrier, and mechanical properties.
