Emulsion-structured pectin-based edible films with whey protein and short-chain dietary fibers for geranylgeraniol encapsulation and strawberry preservation.

ABSTRACT: This study reports the design and characterization of emulsion-structured pectin-based edible films incorporating whey protein concentrate (WPC), short-chain prebiotic fibers (fructooligosaccharides, FOS; galactooligosaccharides, GOS; and xylooligosaccharides, XOS), and annatto seed oil as a source of geranylgeraniol. The formulation strategy combined citrus pectin with WPC and fibers to enhance the structural and functional properties of films while improving oil stabilization. The film-forming emulsions were processed by thermosonication to promote biopolymer dispersion and stable droplet incorporation. All films exhibited desirable technological features, including high encapsulation efficiency of geranylgeraniol (≥70 %). They also showed strong UV-vis light barrier properties and impro
