FILMES DE AMIDOS DE MANDIOCA MODIFICADOS PARA RECOBRIMENTO E CONSERVACA DE UVASdFILMS OF STARCH CASSAVA TO COAT AND CONSERVATION OF GRAPES

摘要

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