Bionanocomposites films applied as active and smart food packaging: A review

Abstract

Food packaging is used worldwide and is a common technique for protecting food safety and quality while increasing shelf life. Environmental issues caused by using polymers in packaging derived from petroleum are becoming more significant and more well‐known. Interest in ecofriendly packaging materials made of renewable resources (biopolymers) has steadily increased, particularly for temporary and throw‐away packaging applications. However, biopolymers frequently have poor processability, poor mechanical, and poor barrier characteristics, restricting their industrial application and scalable manufacturing. Researchers have created bionanocomposites with improved packaging qualities like antibacterial function, mechanical toughness, optical clarity, and gas and water barrier properties to overcome these restrictions. This review seeks to inform readers about recent advances in active food packaging that use biopolymers and bionanocomposite materials. The difficulties and possibilities presented by such resources for the food packaging sector have been examined. This review is timely given the recent spike in interest in research projects both in academia and industry seeking to create a new group of materials for packaging based on biopolymer for food with potential uses elsewhere.

Clay Minerals and Biopolymers in Film Design: Overview of Properties and Applications

“…The potential use of biopolymers such as starch, gum, alginate, chitosan, gelatin, pectin, protein, and others as alternatives to conventional food packaging materials that use synthetic polymers has garnered significant interest due to the increasing popularity of sustainability and environmental protection [6]. In addition to their environmentally friendly attributes, biopolymers also help to prevent the growth of microorganisms in food, thus extending its shelf life.…”

Preparation, Physicochemical, and Cyto- and Genotoxic Characterisation of Polysaccharide Composites Containing Carbon Quantum Dots

“…However, the industrial application of biopolymers is currently limited due to their relatively poor mechanical and barrier properties. The hydrophilic nature of biopolymers makes the development of moisture barrier properties particularly challenging [ 6 ]. The incorporation of carbon quantum dots into their structure represents a promising avenue for enhancing both parameters.…”

Water aging effects on the flexural properties of fully biobased coir fiber composites

“…In recent years, the increase in nondegradable waste accumulated in landfills, mainly polymeric materials derived from petroleum, has generated considerable environmental problems. 1 For this reason, the use of renewable resources to develop biodegradable materials for different applications, such as biomedical, 2 biological, 3 food packing, 4 civil construction, 5 electronic devices 6 and others, 7 has been extensively investigated.…”
