Improving the shelf life of tofu using chitosan/gelatin-based filmsincorporated with Pulicaria jaubertii extract microcapsules

This study aimed to improve the shelf life of fresh tofu (FT) by applying chitosan (CH) and/or gelatin (GEL) films loaded with two concentrations of microcapsules containing Pulicaria jaubertii extract (MPE). The effect of packaging on the shelf life of FT was evaluated based on physicochemical, mic...
