Ferulic acid‐impregnated sodium alginate–pectin biopolymer film for active packaging and shelf‐life extension of potato chips

Key Points

• This research aims to evaluate the efficacy of ferulic acid-impregnated sodium alginate-pectin films for food preservation.
• Developed biopolymer films using sodium alginate and pectin impregnated with ferulic acid.
• Tested antioxidant properties of the films in packaging potato chips.
• SA-P-FA films demonstrated strong antioxidant activity.
• The films significantly extended the shelf life of potato chips by reducing oxidative deterioration.
