Resumen

Descripción

The inhibitory activity of chitosan edible coatings was evaluated against fungus on minimally processed apples. Apples, cv. Gala (Malus domestica) were sliced and coated with an acidic formulation of 2.0 g/L chitosan concentration. Non-classified fungus (predominantly Penicillium sp. and Alternaria sp.) were used to contaminate the cut surfaces and infection extension assessed by means of image analysis. The results show the fungistatic activity of the chitosan with significant reduction on infected area and on the number of infected samples, (40% of chitosan-coated against 90% of non-protected fruits) along 10 days of storage time at 25oC.
