AI Article Synopsis
- - A new type of food packaging was created using zinc-doped titanium oxide (Zn-doped TiO) nanoparticles, which enhances film-forming ability and is biodegradable, aimed at improving the storage of fresh food.
- - Various metal-doped TiO nanoparticles (Zinc, Copper, Selenium) were synthesized and characterized, with Zn-doped nanoparticles showing the strongest antimicrobial properties against harmful food pathogens while having low toxicity.
- - This innovative packaging successfully kept plums fresh for 16 days and decomposes completely in 12 days when stored in natural soil, demonstrating its effectiveness and environmental benefits for food preservation.
Article Abstract
Food packaging reinforced with Zn-doped TiO nanoparticles with enhanced prerequisite film-forming and biodegradable traits was prepared to augment fresh food storage. Pure and tailored metal (Zinc, Copper, and Selenium) doped TiO nanoparticles were synthesized and analyzed through multiple characterization techniques (optical spectra, XRD patterns (X-Ray Diffraction), Dynamic Light Scattering, and Scanning Electron Microscopy). The synthesized nanoparticles were tested for their Minimum Inhibitory Concentrations, antimicrobial potential against common lethal food pathogens, and cytotoxicity. Compared to Cu- and Se-doped nanoparticles, Zn-doped TiO nanoparticles displayed the most potent antimicrobial activity with insignificant cytotoxicity and were incorporated into the food packaging materials. The developed nano-reinforced food packaging efficaciously augmented the freshness of plums (Oemleria cerasiformis) for 16 days (42 ± 2 °C). The physicomechanical characterization of the nano-reinforced packaging establishes its utility in food packaging applications. The developed biodegradable packaging undergoes complete decomposition within 12 days of storage in natural soil.

Quinoa polysaccharides have attracted significant research interest in recent years due to their diverse biological activities, including antiviral, anti-inflammatory, antioxidant, and immunoregulatory properties. These attributes align with the growing global demand for natural, functional food ingredients, positioning quinoa polysaccharides as a valuable resource in food science and technology. This review presents an overview of the various bioactivities of quinoa polysaccharides, critically evaluates the methods used for their extraction and purification, describes their structural characteristics, and discusses their practical applications across multiple areas within the food industry, including food additives, meat products, health foods, and innovative food packaging.

Background: Polyether ether ketone (PEEK) was modified by a sulfuric and nitric acid mixed system to improve the solubility of the material and the gas selective permeability of the film. SN1 and SN5, synthesized from mixed acid systems (with ratios of nitric acid and sulfuric acid of 1:1 and 1:5, respectively) were chosen because they had comparable nitro groups but differing sulfonyl groups. To investigate the impact of the type and content of sulfonated and nitrated polyether ether ketone (SNPEEK) on the structure and physicochemical properties of the films, SN1/polyvinyl chloride (PVC) and SN5/polyvinyl chloride films were made by adding varying amounts of SN1 and SN5 (0.

This study aimed to fabricate edible films from tapioca (T) and potato (P) starch, assessing their physicochemical properties and biodegradation across different ratios (T100P0, T70P30, T50P50, and T30P70). The films underwent evaluation for moisture content, thickness, water vapor permeability, and color values. T100P0 and T30P70 formulations exhibited the highest film transparency at 43.

Unlabelled: A huge amount of fruits and vegetables is being produced and processed in India and therefore the waste is also generated in high quantities. These wastes are good sources of vitamins, enzymes, cellulose, and many other essential compounds. The non-utilization of these bio-wastes leads to economic loss and also environmental problems.
