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 a
