Desenvolvimento de revestimento biodegradável a base de Chlorella vulgaris para conservação de morangos

Abstract

Due to the need to reduce fruit and vegetable waste worldwide, new forms of preservation, such as the use of edible coatings, have been studied, not only to decrease this rate but also to increase the quality of these foods. In this sense, the objective of this study was to evaluate the effect of a biofilm produced with the microalgae Chlorella vulgaris at different concentrations for the conservation of strawberries stored in refrigerated environments. This assay was conducted using dried microalgae biomass diluted with water in four concentrations (1%, 2%, 3% and 4%), and 72-hour intervals analyses over a period of 12 days. The results obtained showed that among the factors analyzed the biofilm with 3 and 4 % concentration were more effective, regarding other concentrations, against weight lost, pH, color, acidity, phenolic compounds, and soluble solids not altering vitamin C, firmness, and dehydration aspects.
