“…To overcome the aforementioned limitations of neat biopolymer-based films, several modification techniques are being applied, such as: the use of cross-linkers like glutaraldehyde, citric acid, calcium chloride, formaldehyde [33,36,37]; the addition of additives like plasticizers; functional components like essential oils; and antimicrobial compounds such as nisin and lysozymes [35,38,39]. Other techniques include hydrophobic modification with structured oil nanoparticles [29,[40][41][42], incorporating organic and inorganic fillers [30], coating biopolymers with synthetic polymers, or a combination of two or more biopolymers having potential packaging properties [43][44][45][46]. The application of novel technologies like high-pressure processing, cold plasma, ultrasonication, high-pressure homogenization, irradiation, and microwaves [47] have also been examined.…”

Biopolymers, like polysaccharides and proteins, are sustainable and green materials with excellent film-forming potential. Bio-based films have gained a lot of attention and are believed to be an alternative to plastics in next-generation food packaging. Compared to conventional plastics, biopolymers inherently have certain limitations like hydrophilicity, poor thermo-mechanical, and barrier properties. Therefore, the modification of biopolymers or their films provide an opportunity to develop packaging materials with desired characteristics. Among different modification approaches, the application of cold plasma has been a very efficient technology to enhance the functionality and interfacial characteristics of biopolymers. Cold plasma is biocompatible, shows uniformity in treatment, and is suitable for heat-sensitive components. This review provides information on different plasma generating equipment used for the modification of films and critically analyses the impact of cold plasma on packaging properties of films prepared from protein, polysaccharides, and their combinations. Most studies to date have shown that plasma treatment effectively enhances surface characteristics, mechanical, and thermal properties, while its impact on the improvement of barrier properties is limited. Plasma treatment increases surface roughness that enables surface adhesion, ink printability, and reduces the contact angle. Plasma-treated films loaded with antimicrobial compounds demonstrate strong antimicrobial efficacy, mainly due to the increase in their diffusion rate and the non-thermal nature of cold plasma that protects the functionality of bioactive compounds. This review also elaborates on the existing challenges and future needs. Overall, it can be concluded that the application of cold plasma is an effective strategy to modify the inherent limitations of biopolymer-based packaging materials for food packaging applications.

“…However, most biodegradable polymers do not exhibit native antimicrobial properties (Agarwal, Hoque, Bandara, et al, 2020; Dhumal et al, 2019; Llana‐Ruiz‐Cabello et al, 2016; Roy & Rhim, 2020), which makes the packaged product susceptible to microbial contamination. To impart antimicrobial properties to the packaging systems, different types of active antimicrobial agents can be incorporated to enhance the film functionality (Abdulmumeen et al, 2012; Agarwal, Hoque, Mohapatra, et al, 2020). These active ingredients inhibit microbial growth significantly and delay the lipid oxidation of food products, ultimately leading to increased shelf life as these factors are the primary reason for food spoilage.…”

Aquatic food products, including fish and crustaceans, are some of the most consumed foods globally and are highly prone to microbial contamination. Such products have been preserved using conventional processing techniques such as freezing, cold storage, modified atmospheric packaging (MAP), and vacuum packaging. However, these techniques have been used since decades and are not cost‐effective. Therefore, alternative sustainable strategies need to be explored. One viable option is the application of biopolymer‐based films and coatings loaded with active antimicrobial agents (peptides and essential oil components) for the preservation of aquatic food products. Nisin is the most widely used peptide for the development of antimicrobial coatings, while eugenol, carvacrol, and cinnamaldehyde are among the most popular essential oil compounds. Findings reveal that both peptides and essential oils, when applied in combination within a coating system, demonstrate robust antimicrobial activity, delayed lipid oxidation, and retain the overall quality of the aquatic food system. Novelty impact statement Antimicrobial‐based coating systems have recently gained worldwide attention due to their ability to delay food contamination and maintain product quality throughout the storage period. This review provides a comprehensive description of peptide and essential oil‐loaded coating systems and their application in the shelf‐life extension of aquatic food products. In addition, the application of nanocomposite systems for the preservation of aquatic foods has been discussed.

“…Biopolymers like polysaccharides and proteins from plant or animal origins are being explored to develop packaging materials. Previous studies showed that biopolymer-based films have good film-forming capacity but this packaging system exerts certain shortcomings like low mechanical strength, high hydrophilicity, and poor barrier property as compared to synthetic plastics [ 21 , 22 , 23 , 24 ]. These limitations can be overcome by the application of HPP.…”

Suitable packaging material in combination with high-pressure processing (HPP) can retain nutritional and organoleptic qualities besides extending the product’s shelf life of food products. However, the selection of appropriate packaging materials suitable for HPP is tremendously important because harsh environments like high pressure and high temperature during the processing can result in deviation in the visual and functional properties of the packaging materials. Traditionally, fossil-based plastic packaging is preferred for the HPP of food products, but these materials are of serious concern to the environment. Therefore, bio-based packaging systems are proposed to be a promising alternative to fossil-based plastic packaging. Some studies have scrutinized the impact of HPP on the functional properties of biopolymer-based packaging materials. This review summarizes the HPP application on biopolymer-based film-forming solutions and pre-formed biopolymer-based films. The impact of HPP on the key packaging properties such as structural, mechanical, thermal, and barrier properties in addition to the migration of additives from the packaging material into food products were systemically analyzed. HPP can be applied either to the film-forming solution or preformed packages. Structural, mechanical, hydrophobic, barrier, and thermal characteristics of the films are enhanced when the film-forming solution is exposed to HPP overcoming the shortcomings of the native biopolymers-based film. Also, biopolymer-based packaging mostly PLA based when exposed to HPP at low temperature showed no significant deviation in packaging properties indicating the suitability of their applications. HPP may induce the migration of packaging additives and thus should be thoroughly studied. Overall, HPP can be one way to enhance the properties of biopolymer-based films and can also be used for packaging food materials intended for HPP.
