Estimación de vida útil de mora de castilla (Rubus glaucus Benth) a partir del recubrimiento de celulosa bacteriana producida por Komagataeibacter xylinus

Abstract

The Blackberry (Rubus glaucus Benth) is an Andean crop with nutritional and antioxidant properties, whose intake potentiates the immune system and reduces the risk of developing degenerative and cardiovascular diseases. However, it is one of the most perishable fruits due to its high respiration rate and the lack of peel that protects the quality of the fruit, which makes it susceptible to microbial attack and rapid deterioration, which is a problem for commercialization. The objective of this research was to estimate the useful life of Castile mulberry (Rubus glaucus Benth) from the coating of bacterial cellulose produced by Komagataeibacter xylinus, applied in the postharvest quality of the Mora de Castilla, with the purpose of improving both physicochemical characteristics as nutritional. The treatment with biofilm coating of bacterial cellulose at a temperature of 4 Celsius degree allowed to increase the shelf life of the fruit up to 9 days, in addition to maintaining its characteristic texture, color, smell and taste, that is to say that the biofilm generated from Komagataeibacter xylinus, can be used as an antimicrobial agent, in edible coatings for fruits, vegetables, meats, etc.
