Effect of amaranthus viridis e bidens pilosa leaves extract on properties of soy protein-locust bean gum active films

The present study aimed to manufacture active biodegradable films from soy protein isolate (SPI), locust bean gum (LBG) and caruru blackjack leaf extract. interaction between the compounds was evaluated through analysis of FTIR. effect extract addition on microstructure, mechanical properties, antioxidant capacity, UV radiation absorption color opacity film were evaluated. All extracts interacted with protein, however only two treatments LBG in film. Addition provided an increase activity. increased tensile strength films, but reduced their elasticity. extract, however, not favoring resistance films. darkened more greenish than all other made containing presented a higher intensity light spectral range ultraviolet A C.
