Inducing covalent cross-links in soy protein film through ferulic acid incorporation and UV irradiation and its effect on film properties

Key Points

• This research aims to explore how ferulic acid and UV-C curing influence the characteristics of soy protein films.
• Incorporation of ferulic acid into soy protein isolate films
• Exposure of films to UV-C light for curing
• Assessment of physical and mechanical properties of resulting films
• Ferulic acid significantly enhanced the strength and flexibility of soy protein films.
• UV irradiation improved the stability and barrier properties of the films.
• Covalent cross-linking led to a more durable film structure.
