A Comprehensive Review of the Development of Carbohydrate Macromolecules and Copper Oxide Nanocomposite Films in Food Nanopackaging

Abstract

Background. Food nanopackaging helps maintain food quality against physical, chemical, and storage instability factors. Copper oxide nanoparticles (CuONPs) can improve biopolymers’ mechanical features and barrier properties. This will lead to antimicrobial and antioxidant activities in food packaging to extend the shelf life. Scope and Approach. Edible coatings based on carbohydrate biopolymers have improved the quality of packaging. Several studies have addressed the role of carbohydrate biopolymers and incorporated nanoparticles to enhance food packets’ quality as active nanopackaging. Combined with nanoparticles, these biopolymers create film coatings with an excellent barrier property against transmissions of gases such as O2 and CO2. Key Findings and Conclusions. This review describes the CuO-biopolymer composites, including chitosan, agar, cellulose, carboxymethylcellulose, cellulose nanowhiskers, carrageenan, alginate, starch, and polylactic acid, as food packaging films. Here, we reviewed different fabrication techniques of CuO biocomposites and the impact of CuONPs on the physical, mechanical, barrier, thermal stability, antioxidant, and antimicrobial properties of carbohydrate-based films.

Metal and Metal Oxides Nanoparticles as Nanofillers for Biodegradable Polymers

“…Moisture sensitivity and functional properties of films were evaluated, as well, regarding their potential application for fresh food preservation. [113,114] In contrast, Numaga et al [115] used poly(acrylic acid) as a surface modifier for copper nanoparticles (CuNPs) and studied the effect of PAA molecular weight on the size and stability of the resulting CuNPs. It turned out that the average particle size decreased as the molecular weight of PAA increased.…”

Copper‐based nanoparticles for biopolymer‐based functional films in food packaging applications

“…Copper‐based nanofillers, like other nanofillers, play an important role in improving various performances, such as the mechanical and barrier properties of bio‐based packaging films. Various copper‐based nanofillers, such as copper or copper oxide nanoparticles, copper sulfide nanoparticles, and copper‐doped alloys, are being utilized to develop biodegradable food packaging films (Dash et al., 2022; Mesgari et al., 2022). Copper oxide nanoparticles (CuONPs) have been mainly used to manufacture biopolymer‐based antimicrobial packaging films, but recently, copper sulfide and copper‐doped nanoparticles are also being explored (Huang et al., 2017; Roy & Rhim, 2021; Roy et al., 2022; Sooch & Mann, 2021).…”

Recent advances in quality preservation of postharvest golden needle mushroom (Flammulina velutiper)

“…Food packaging aims to protect food products from harmful microorganisms and their toxins, chemical compounds, sunlight, temperature, permeable volatile compounds, oxygen and humidity. 82 Recently, the application of nano-packaging for postharvest preservation of F. velutiper using systematic research has gained considerable attention (Table 1). Fang et al investigated the effect of a PE packaging material containing nano-Ag, nano-TiO 2 and nano-SiO 2 on the storage stability of F. velutiper.…”
