Special Issue Information

Dear Colleagues,

Food safety, quality, and security are growing concerns around the globe due to the increasing population. Food packaging is one of the fastest developing sectors and it has been estimated that the commercial market may extend to around $600 billion by 2026. In recent years, a considerable number of synthetic polymers have been replaced by biodegradable polymers in food packaging to address plastic pollution and greenhouse gas emissions. Nevertheless, the lack of mechanical features, moisture sensitivity, and being prone to microbial contamination are the major limitations of state-of-the-art biodegradable packaging materials. There is a huge global demand for renewable and biodegradable food packaging for sustainability. Active and intelligent packaging are cutting-edge technologies to ensure food safety, quality, and security. Functionalized nanocomposites have been investigated for their biosensing features and real-time monitoring of food spoilage by microbes and other factors (intrinsic and extrinsic). Natural antimicrobial agents have been commonly preferred in active packaging owing to their abundance, biocompatibility, and biodegradability.

The reinforcement of biodegradable polymers with functional nanomaterials and natural additives can enhance the physicochemical, mechanical, biosensing, antioxidant, and antimicrobial features. Physical, chemical, and enzymatic modifications of the biopolymer have been also employed to improve the functional features of packaging films. These treatments and innovative coating technologies in packaging materials could also extend the shelf life of food and reduce the risk of life-threatening pathogens.

The main aim of this Special Issue is to disclose the significance of the latest development in sustainable food packaging. We are pleased to invite submissions in the form of original research articles, short communications, letters, prospects, and mini reviews that reflect the key findings on the significance of biodegradable polymers and nanomaterials in active and intelligent food packaging.

This Special Issue is not limited to active and intelligent packaging but also welcomes manuscripts on electrospun nanofibers, kinetics on the release of active components, edible films/coatings processing, encapsulation techniques, life cycle analysis, novel techniques of biopolymer extraction, waste valorization, quorum sensing, bionanocomposites, naturally derived polysaccharides/proteins, structural modification of biopolymers, circular bioeconomy, modeling, etc.

Multilayer coating can be applied on fresh fruit to protect and enhance its shelf life. This study evaluated the application of a multilayer protein and chitosan coating on fresh cherimoya. To determinate the effect of the multilayer coating on the shelf life on the fruit, total phenolic content, pH, °Brix, weight loss, and hardness values were tested. The ripening process is associated with an increase of soluble solids, and results showed that the presence of the multilayered coating maintains the total phenolic content, pH, and °Brix values over time while reducing the water loss. This effect is probably due to the presence of the coating that creates a barrier on the food surface that reduces the respiration rate and affects the ripening process, demonstrating the method’s feasibility to be used to enhance the shelf life of fresh-cut cherimoya.

The growing demand for fresh-cut products has led to an increasing interest in the study of enhancing the quality of ready-to-eat products. Eggplants are consumed as fresh-cut vegetables, which represent an increasing consumption rate. To extend the shelf life of the product, combination treatments have been proposed to inhibit the browning index (BI). Moreover, the storage temperature (4, 16, 25 °C), the concentration of ascorbic acid (AA) (1, 2, 3, and 4 g/L), and modified atmosphere packaging (MAP) (MAP-1, O2: 80 Kpa + CO2: 0 Kpa; MAP-2, O2: 5 Kpa + CO2: 15 Kpa; MAP-3, O2: 10 Kpa + CO2: 10 Kpa; MAP-4, O2: 15 Kpa + CO2: 5 Kpa; MAP-5, O2: 0 Kpa + CO2: 80 Kpa) are screened through the BI of fresh-cut eggplant. Then, the effect of AA combined with MAP on the BI, phenolic content, and polyphenol oxidase (PPO) of fresh-cut eggplants is investigated over four days. In particular, two different areas of fresh-cut eggplant with seed and without seed were chosen to measure the BI. The result shows that the proper temperature (16 °C) maintains the BI of fresh-cut eggplant with seed during two days through screening. The screening of AA demonstrates that AA of 2 g/L is the better concentration to protect the color of fresh-cut eggplant with seed and without seed. AA of 2 g/L shows lower BI for fresh-cut eggplant with seed and without seed in MAP-2, MAP-3, MAP-4. The combination of AA (2 g/L) and MAP-2 significantly inhibited the browning of fresh-cut eggplants with seed. The application of AA (2 g/L) combined with MAP-2 inhibits the PPO and total phenol content activity over two and three days. Taken together, using AA combined with MAP may constitute a potential approach for maintaining the quality and inhibiting the browning of fresh-cut eggplants. Full article
