SUMMARY:

Disposal into the environment of a large volume of plastic packaging that is difficult to degrade, used to package food,
as well as the improper disposal of agro-industrial waste has received attention for causing environmental pollution. In
this sense, new biologically-based materials have been studied and proposed in an attempt to minimize these effects.
Biopolymers can be obtained from plant sources, and by-products from the food industry are potential raw materials
for this application. Therefore, the objective of this study was to develop films as packaging materials for application in
food based on by-products resulting from the agro-industrial processing of Prata bananas. With this, it aims to provide
solutions to environmental problems, both by providing a new packaging material as an alternative to fossil raw
materials, and by valuing these co-products and adapting their disposal to the environment. For this purpose, the
banana silver fruits acquired in local commerce with a standardized degree of maturation were used and their peels
were prepared in a wet and also dried way under controlled temperature conditions. The development of the films
proceeded by the “casting” method. Formulations were tested for the production of biopolymeric packaging films
based on wet and dry shells, with glycerol being incorporated to improve plasticization. In order to know their
characteristics, the co-products were investigated regarding their moisture profile, water activity, acidity, pH, in addition
to their antimicrobial activity. The properly formed films were characterized as to their antioxidant activity, thickness
and visual appearance. With this, it was concluded that the study was of great importance to provide new biopolymeric
films naturally antimicrobial as packaging materials, from renewable sources as alternatives to fossil raw materials and
the valorization of agro-industrial by-products. It also achieved outstanding relevance for providing solutions to
environmental problems and food conservation with the minimization of the addition of chemical additives in food, thus
presenting a social, sanitary and environmental bias.
