The main aim of this study was to carry out an in vitro digestion of gelatin-based films and nanocomposite films activated with Pitanga (Eugenia uniflora L.) leaf extract (PLE) encapsulated in a W/O/W double emulsion. Also, the effects of encapsulation and addition of crystalline nanocellulose on PLE bioaccessibility, and on Caco-2 cells viability, after in vitro digestion, were evaluated. The free PLE, W/O (SE...
