Bioactive and Biodegradable Films Packaging Incorporated with Acca Sellowiana Extracts: Physicochemical and Antioxidant Characterization

Abstract

In this work a new biodegradable film was developed, and bioactive compounds from Acca sellowiana were incorporated. Film packaging production was carried out from an aqueous filmogenic solution, with a blend of Brazilian pine seeds starch, citric pectin, glycerol and aqueous extract from pulp and husk of Acca sellowiana. In all the films produced were evaluated the physicochemical and antioxidant properties. The films produced presented lower moisture content, and extracts from pulp and husk affect the moisture content and the water solubility of the films. Evaluating the light transmittance, films with husk extract addition presented (p<0.05) a reduction of luminosity and an increase of opacity. Films produced with husk extract presented a higher content of total phenolic and flavonoids compounds, and this fact promoted a high antioxidant activity by DPPH, ABTS and FRAP assay. Bioactive and biodegradable films produced with Brazilian pine seed starch, citric pectin and Acca sellowiana extracts presented good physicochemical and antioxidant parameters, and may be an alternative to packaging in food systems.
