“…Lipid-based NCS interfere with the hydrogen bonding of bioactive coatings, reducing their rigidity and resistance while increasing their extensibility. On the other hand, nisin owing to its more amorphous nature increased the rigidity of the packaging film, which reduced the mechanical strength (Motta et al, 2020 ). Similar results have been reported previously, where the addition of polymeric NCS improved the mechanical properties of the bioactive coatings (Hasheminya et al, 2018 ; Jafarzadeh & Jafari, 2020 ).…”

To meet the demands for more effective and ecofriendly food packaging strategies, the potential of nisin-loaded rhamnolipid functionalized nanofillers (rhamnosomes) has been explored after embedding in hydroxypropyl-methylcellulose (HPMC) and κ-carrageenan (κ-CR)-based packaging films. It was observed that intrinsically active rhamnosomes based nanofillers greatly improved the mechanical and optical properties of nano-active packaging (NAP) films. Incorporation of rhamnosomes resulted in higher tensile strength (5.16 ± 0.06 MPa), Young’s modulus (2777 ± 0.77 MPa), and elongation (2.58 ± 0.03%) for NAP than active packaging containing free nisin (2.96 ± 0.03 MPa, 1107 ± 0.67 MPa, 1.48 ± 0.06%, respectively). NAP demonstrated a homogenous distribution of nanofillers in the biopolymer matrix as elucidated by scanning electron microscopy (SEM). Thermogravimetric analysis (TGA) confirmed that NAP prepared with nisin-loaded rhamnosomes was thermally stable even above 200 °C. Differential scanning calorimetry (DSC) analyses revealed that addition of nisin in nanofillers resulted in a slight increase in Tg (108.40 °C), indicating thermal stability of NAP. Fourier transform infrared spectroscopy (FTIR) revealed slight shift in all characteristic bands of nano-active packaging, which indicated the embedding of rhamnosomes inside the polymer network without any chemical interaction. Finally, when tested on chicken breast filets and cheese slices under refrigerated storage conditions, NAP demonstrated broad-spectrum antimicrobial activity (up to 4.5 log unit reduction) and inhibited the growth of Listeria monocytogenes , Staphylococcus aureus , Pseudomonas aeruginosa , and Escherichia coli . These results suggest that HPMC and κ-CR-based NAP containing functionalized nanofillers can serve as an innovative packaging material for the food industry to improve the safety, quality, and shelf-life of dairy and meat products.

SummaryThis research endeavoured to explore the potential application of thyme essential oil (TEO) in the production of cassava starch (CS) films for active packaging. The study incorporated TEO both in its unencapsulated form and encapsulated through complex coacervation into the cassava starch film. The antimicrobial properties of the resulting films were assessed. The control films and those exhibiting antimicrobial activity were subjected to extensive physicochemical characterisation, including measurements of thickness, mechanical properties, visual analysis using atomic force microscopy (AFM), colour, luminosity, opacity, Fourier transform infrared spectroscopy (FTIR), moisture content, solubility, and vapour transmission. The outcomes indicated that the presence of TEO, whether in its unencapsulated or encapsulated form, significantly affected the roughness of the CS films, reducing their solubility and enhancing their hydrophobicity compared to the control. It was also observed that unencapsulated TEO negatively impacted the films' integrity, whereas encapsulated TEO displayed a synergistic effect with CS films, improving their barrier properties and suggesting their potential use in food packaging applications.

The accumulation of high amounts of petro-based plastics is a growing environmental devastation issue, leading to the urgent need to innovate eco-safe packaging materials at an equivalent cost to save the environment. Among different substitutes, starch-based types and their blends with biopolymers are considered an innovative and smart material alternative for petrol-based polymers because of their abundance, low cost, biodegradability, high biocompatibility, and better-quality film-forming and improved mechanical characteristics. Furthermore, starch is a valuable, sustainable food packaging material. The rising and growing importance of designing starch-based films from various sources for sustainable food packaging purposes is ongoing research. Research on “starch food packaging” is still at the beginning, based on the few studies published in the last decade in Web of Science. Additionally, the functionality of starch-based biodegradable substances is technically a challenge. It can be improved by starch modification, blending starch with other biopolymers or additives, and using novel preparation techniques. Starch-based films have been applied to packaging various foods, such as fruits and vegetables, bakery goods, and meat, indicating good prospects for commercial utilization. The current review will give a critical snapshot of starch-based films’ properties and potential applicability in the sustainable smart (active and intelligent) new packaging concepts and discuss new challenges and opportunities for starch bio composites.
