Effect of Biodegradable Coatings on the Growth of In Vitro, on Maize Grains, and on the Quality of Tortillas during Storage.

The fungus causes serious damage to maize grains and its by-products, such as tortilla. Currently, animal and plant derivatives, such as chitosan and propolis, and plant extract residues, respectively, are employed as alternatives of synthetic fungicides. The objective of this research was to evaluate the efficacy of several formulations based on propolis-chitosan-pine resin extract on the in vitro growth of , the growth of maize grain plantlets and the quality of stored tortillas at 4 and 28 °C.
