Abstract

Biopolymer films with antimicrobial properties offer a promising solution for enhancing food preservation by providing an effective barrier against microbial growth and extending shelf life. These films, derived from natural sources such as starch, chitosan, alginate, and cellulose, can be functionalized with antimicrobial agents, such as essential oils, plant extracts, or nanoparticles, to inhibit the growth of bacteria, fungi, and molds on food surfaces. The integration of these biopolymer films into food packaging systems helps reduce the need for chemical preservatives while promoting sustainability and environmental friendliness. This paper explores the development and application of antimicrobial biopolymer films in food preservation, discussing their antimicrobial mechanisms, advantages, and challenges. The potential for these films to be used in various food packaging applications, including fresh produce, dairy, meat, and bakery products, is also highlighted. By offering an alternative to traditional food preservation methods, antimicrobial biopolymer films contribute to the advancement of safer, more sustainable food packaging solutions.
