Edible barrier films from aqueous dispersions of zein nanoparticles: effect of polyols

Key Points

• Enhanced barrier properties of edible films improve packaging solutions, leading to reduced food spoilage.
• The study shows that polyols significantly influence the properties of zein-based films, impacting their effectiveness.
• Assessment of the film characteristics was conducted by measuring moisture permeation and mechanical strength.
• These findings suggest that incorporating polyols into zein nanoparticles may enhance the sustainability of food packaging.
