Chitosan based antimicrobial films for food packaging applications

Abstract

Antimicrobial packaging is one of the most promising active packaging systems. Antimicrobial packaging is the packaging system that is able to kill or inhibit spoilage and pathogenic microorganisms that are contaminating foods. A tremendous effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservation, chitosan films are very effective. Chitosan has widely been used in antimicrobial films, to provide edible protective coating, dipping and spraying for the food products due to its antimicrobial properties. Chitosan can be formed into fibers, films, gels, sponges, beads or nanoparticles. Chitosan films have been used as a packaging material for the quality preservation of a variety of food. Chitosan has great potential for a wide range of applications due to its biodegradability, biocompatibility, antimicrobial activity, non-toxicity and versatile chemical and physical properties. The present review outlines the preparation and antimicrobial activity of chitosan based films.

Effects of Polysaccharide-Based Edible Coatings on Quality and Antioxidant Enzyme System of Strawberry during Cold Storage

“…Edible coatings are proposed as viable alternatives for the preservation of fresh food such as fruit, vegetable, fish, and meat due to their capabilities to prevent moisture loss, aromas loss, solute transport, water absorption in food matrix, or oxygen penetration [23]. Edible coatings from polysaccharides have been applied to extend shelf life and preserve quality of foods.…”

Development of chitosan based edible films: process optimization using response surface methodology

“…In addition, chitosan is an excellent edible film component due to its film-forming capacity and good mechanical properties and can form transparent films, which can fulfill various packaging needs (Srinivasa et al 2002). As compared with other bio-based food packaging materials, chitosan-based films have also been claimed as effective carriers of many functional ingredients, such as antimicrobial agents and antioxidants to extend storage quality of food (Tripathi et al 2008, Pranoto et al 2005, Park and Zhao 2004. Chitosan films can be prepared by cross-linking with agylcone geniposidic acid (Mi et al 2006), ternary chitosanglucomann-nisin (Li et al 2006), blending of ferulic acid incorporated starch chitosan (Mathew and Abraham 2008), incorporation of garlic oil, potassium sorbate and nisin (Pranoto et al 2005), chitosan-potato starch film using microwave treatment (Tripathi et al 2008), starch/chitosan blend film under the action of irradiation (Zhai et al 2004) and water soluble chitosan and amylose film (Suzuki et al 2005) etc.…”

“…Selain itu kitosan harganya relatif murah karena ketersediaannya di alam cukup melimpah, kelarutannya tinggi dan mudah dibuat menjadi film. Pada saat ini kitosan banyak digunakan sebagai bahan pengemas makanan, serat untuk bahan diet dan aplikasi biomedis untuk penghantar obat (drug delivery) (Tripathi, Mehrotra, dan Dutta 2008;Schnürch and Dünnhaupt 2012;Anitha et al 2014).…”
