【 摘 要 】

In this article,films were produced with six types of cassava's starch mixed with gelatin andplasticized with sorbitol. These films were used in covering of grapes 'Benitaka'(Vitis vinifera L.) as biodegradable packaging. The acetylated starch film showedthe best results in solubility, thickness and homogeneity, besides the lesswater loss the fruit, resulting in better coverage, increasing the shelf lifefruits in 12 days. These results demonstrate the great potential of using filmsin food conservation, adding value to agricultural activity and helping to reducenon-biodegradable plastics in the environment.
