Properties of Edible Films Based on Fruits and Vegetables Stabilityandshelf-life Edible films based on fruits and vegetables might be considered as dehydrated foods when it comes to legislation and stability criteria. Those films have sufficient nutrients to serve as substrates for microbial growth. Unless they are aseptically packaged within an external packaging material, stability should be maintained mainly by water removal. The peach puree edible films produced in the pioneer study of McHugh and others (1996) presented a water activity of 0.43, which is low enough to avoid microbial growth. The same was not true for the puree itself, which had awater activity of 0.95. Similarly, low water activity values (lower than 0.6) were reported for films from wine grape pomace extract (Deng and Zhao 2011) and from mango puree (Sothornvit and Rodsamran 2008). Such low water activity values make these films expected to be microbiologically stable as long as they are properly stored under dry conditions. Higher water activity values (0.66 to 0.70) were observed in thermoplastic starch (TPS) films added by mango, acerola, and red mombin purees (Dantas and others 2015). Sugar crystallization may also lead to unsuitable physicalperformanceofediblefilmsbasedonfruitsandvegetables. This process was not observed in mango puree edible films by Sothornvit and Rodsamran (2008) for up to 3 mo at 30 °C. However, no other studies have investigated the shelf-life of edible films based on fruits and vegetables, although this information is essential for the successful commercialization of such products.
