| Resumen: | The aqueous extract of two ecotypes of murta (Ugni molinae Turcz) leaves (Soloyo Grande ‘‘SG’’ and Soloyo Chico ‘‘SC’’), were analysed for their antioxidant capacity, SC extract exhibiting a higher antioxidant capacity than SG extract. This difference affects physical properties of tuna-fish (Thunnus tynnus) gelatin-based edible films with incorporated murta leaves extract. Dynamic viscoelastic studies, scanning electron microscopy (Cryo-SEM) and SDS-PAGE denoted a certain degree of interference of polyphenolic compounds in the arrangement of gelatine molecules. The addition of the murta extracts leads to transparent films with increased protection against UV light as well as antioxidant capacity. |
