Filmes biodegradáveis à base de amido para aplicação em pequenas produções de frutas

Abstract

The objective of this work was to characterize and identify the best artisanal formulation of biodegradable films based on starch for application in small fruit productions. The test was conducted in a completely randomized design, in a 2 x 2 factorial scheme, with five replications. The data were subjected to analysis of variance and the means were compared using the Scott-knott test. A 5% probability was considered for all the tests mentioned. The best formulation of the mixture was the concentration of 2g of sour powder and 0.08g of glycerin as a plasticizer, in addition to 0.03g of cinnamon as an antimicrobial agent in 100mL of filtered water. This formulation showed a better visual aspect in the formation of the film, less water activity and better flexibility, in addition to rapid biodegradability.
