Special Issue Information

Dear Colleagues,

Designing and preparing degradable coatings or films with excellent antibacterial or preservative properties is one of the most important measures to tackle the food security and environmental sustainability issues that are present globally. Although partially degradable materials have been shown to be promising alternatives to petroleum-based materials, they present special limitations in their physicochemical properties (mechanical properties, moisture and water resistance and heat resistance, degradable properties, etc.) and antibacterial efficacy, release profile, and safety that must be improved before their application in packaging food systems. Recent advances refer to the development of new natural antibacterial ingredients, green modification technology and innovative structure design of composite films to enhance the performance of films or coatings that are currently under study. In addition, the embedding technology of antibacterial ingredients or design of intelligent responsive antibacterial films or coatings to achieve the efficient, stable and intelligent release of active antibacterial ingredients has also contributed to the preservation of meat, flour products, fruits and vegetables, shelf-life extension and protection of food quality and sensory properties during storage.

The nonantimicrobial properties and relatively poor mechanical properties of hydroxyethyl cellulose (HEC) limit its use in packaging. Sulfated rice bran polysaccharides (SRBP) possess significant antioxidant and antimicrobial activities. The purpose of this study was to investigate the effect of different concentrations of SRBP on the physical and mechanical properties and the functional characteristics of HEC/SRBP films. The physical properties of the HEC/20% SRBP films, such as water resistance, water vapor barrier, light barrier, and tensile strength, improved significantly (p < 0.05) compared with those of the HEC films. Scanning electron microscopy and Fourier transform infrared spectrometry showed that HEC formed hydrogen bonds with SRBP and exhibited better compatibility. Thermogravimetric analysis revealed that the addition of SRBP was beneficial to the thermal stability of the films. In addition, the antioxidant and bacteriostatic properties of the films were enhanced by the addition of SRBP to HEC, with the 20% SRBP films showing the most significant enhancement in activity. Therefore, the HEC/20% SRBP films show potential for development for use as active food packaging. Full article
