Special Issue Information

Dear Colleagues,

Nanotechnology can be used to create nanomaterials with unique morphologies, structures, and surface properties, which could possibly improve production processes to provide products with better characteristics and new functionalities in aspects of the food chain including storage, quality monitoring, bioprocessing, and food packaging. Functional nanomaterials that are decorated with antibacterials, antioxidants, enzymes, plant extracts, antibodies, and other biological substances exemplify the great significance and advantages of nanotechnology in the area of food analysis and packaging. Intelligent, smart, and active packaging systems produced using nanotechnology would be able to extend products’ shelf life and maintain food safety, as well as respond to environmental conditions. Sensors or detection systems for rapid detection of spoilage, for quality control, and for pesticide abuse detection at source are also possible through nanotechnology. This Special Issue aims to cover the most recent advances made on nanotechnology fields, from the design, conception, and characterization of nanomaterials to their application in food packaging and analysis. We kindly invite you to submit your contribution to the Special Issue entitled “Application of Nanotechnology in Food Analysis and Packaging”. Up-to-date original research articles, review works, and short communications on these topics are welcome, and we look forward to receiving your interesting work.

In this study, colorimetric indicator nanofiber films based on ethyl cellulose (EC)/gelatin (G) incorporating purple sweet potato anthocyanins (PSPAs) were designed via electrospinning technology for monitoring and maintaining the freshness of pork. The film presented good structural integrity and stability in a humid environment with water vapor permeability (WVP) of 6.07 ± 0.14 × 10−11 g·m−1s−1Pa−1 and water contact angle (WCA) of 81.62 ± 1.43°. When PSPAs were added into the nanofiber films, the antioxidant capacity was significantly improved (p < 0.05) with a DPPH radical scavenging rate of 68.61 ± 1.80%. The nanofiber films showed distinguishable color changes as pH changes and was highly sensitive to volatile ammonia than that of casting films. In the application test, the film color changed from light pink (fresh stage) to light brown (secondary freshness stage) and then to brownish green (spoilage stage), indicating that the nanofiber films can be used to detect the real-time freshness of pork during storage. Meanwhile, it could prolong the shelf life of pork by inhibiting the oxidation degree. Hence, these results suggested that the EC/G/PSPA film has promising future for monitoring freshness and extending shelf life of pork. Full article
