Cellulose nanoreinforcements have been used to improve mechanical and barrier properties of
biopolymers, whose performance is usually poor when compared to those of synthetic polymers. Nanocomposite
edible films have been developed by adding cellulose nanofibers (CNF) in different concentrations (up to 36 g/100 g)
as nanoreinforcement tomango puree based edible films. The effect of CNF was studied in terms of tensile properties,
water vapor permeability, and glass transition temperature (Tg) of the nanocomposite films. CNFwere effective
in increasing tensile strength, and its effect on Young’smodulus was even more noticeable, especially at higher concentrations,
suggesting the formation of a fibrillar network within thematrix. The addition of CNFwas also effective
to improve water vapor barrier of the films. Its influence on Tg was small but significant. The study demonstrated
that the properties ofmango puree edible films can be significantly improved through CNF reinforcement
