Bitter potato starch‐based film enriched with copaiba leaf extract obtained using supercritical carbon dioxide: Physical–mechanical, antioxidant, and disintegrability properties

Films based on bitter potato starch (BPS) and its blends with chitosan (BPS‐Ch) or soy protein isolate (BPS‐SPI) loaded with copaiba leaf extract (E) are prepared via the casting method. The physical–mechanical and antioxidant properties of the as‐prepared films are compared with those of a control....

Zusammenfassung:Films based on bitter potato starch (BPS) and its blends with chitosan (BPS‐Ch) or soy protein isolate (BPS‐SPI) loaded with copaiba leaf extract (E) are prepared via the casting method. The physical–mechanical and antioxidant properties of the as‐prepared films are compared with those of a control. Moreover, the half‐maximal degradation (t50) of the prepared films is calculated by fitting the Hill model to disintegrability kinetic data. Among the analyzed films, BPS‐Ch‐E exhibits the lowest (p
