Recently, academic research and industries have gained awareness about the economic, environmental, and social impacts of conventional plastic packaging and its disposal. This consciousness has oriented efforts towards more sustainable materials such as biopolymers, paving the way for the “green era” of food packaging. This review provides a schematic overview about polymers and blends of them, which are emerging as promising alternatives to conventional plastics. Focus was dedicated to biopolymers from renewable sources and their applications to produce sustainable, active packaging with antimicrobial and antioxidant properties. In particular, the incorporation of plant extracts, food-waste derivatives, and nano-sized materials to produce bio-based active packaging with enhanced technical performances was investigated. According to recent studies, bio-based active packaging enriched with natural-based compounds has the potential to replace petroleum-derived materials. Based on molecular composition, the natural compounds can diversely interact with the native structure of the packaging materials, modulating their barriers, optical and mechanical performances, and conferring them antioxidant and antimicrobial properties. Overall, the recent academic findings could lead to a breakthrough in the field of food packaging, opening the gates to a new generation of packaging solutions which will be sustainable, customised, and green.

Polysaccharide-based materials created by physical processes have received considerable attention for biomedical applications. These structures are often made by associating charged polyelectrolytes in aqueous solutions, avoiding toxic chemistries (crosslinking agents). We review the principal polysaccharides (glycosaminoglycans, marine polysaccharides, and derivatives) containing ionizable groups in their structures and cellulose (neutral polysaccharide). Physical materials with high stability in aqueous media can be developed depending on the selected strategy. We review strategies, including coacervation, ionotropic gelation, electrospinning, layer-by-layer coating, gelation of polymer blends, solvent evaporation, and freezing–thawing methods, that create polysaccharide-based assemblies via in situ (one-step) methods for biomedical applications. We focus on materials used for growth factor (GFs) delivery, scaffolds, antimicrobial coatings, and wound dressings.

The objective of this research was to extract and characterize the pectin from the fruit peels of Ethiopian prickly pears (EPP) (Opuntia ficus-indica) using microwave assisted method.Solution pH and microwave potential were optimized using different pH values (1, 3, and 4) and power (300, 400, and 500 W), respectively, to extract ameliorated pectin yield. The pectin yield for EPP varied between 2.3 and 10.0 percent. At a pH of 1.0 with 400 microwave intensity, the highest yield was seen (14.0 %). The extracted pectin from EPP had a 25.16 % ash content; however, the pectin sample contained less water and weighed less than the control sample. Amount of methoxyl, anhydrouronic acid, and degrees of esterification were determined to be 2.28, 25.58, and 49.87, respectively. Further, transforming the acquired pectin from EPP into a bio-based film as well as evaluating its properties. As a result of this study, a new function was given to EPP waste, and biofilms were developed with cellulose-reinforced modification. Films were prepared using the film-casting method. The pectin-based biofilm (EPP-F) is plant-based biodegradable and has competitive mechanical properties compared with some of the commodity plastics. Therefore, with further improvements, EPP-F could be potentially used for nonstructural applications, such as a sustainable packaging material for the food industry.
