Development of Environmentally Friendly and Intelligent Food Packaging Bio-Nanocomposite Films

Abstract

Researchers are actively exploring biodegradable biocomposite films as environmentally friendly packaging solutions. Increasing consumer demand for a healthy and secure lifestyle led to a serious recent study into the development of intelligent food packaging bio-nanocomposite films aiming not only contribute to sustainability but also possess advanced functionalities through the integration of nanotechnology and intelligent features. This research focuses on the development of active and pH-responsive bio-nanocomposite films by incorporating various concentrations of SPE anthocyanins into the nanoparticle of the CH-PSPS matrix using the solvent-casting method. Thorough examination and characterization of the films revealed a smooth and compact surface, indicative of a uniform distribution of SPE anthocyanins within the matrix as observed through AFM analysis. The inclusion of SPE anthocyanins resulted in a significant increase in antioxidant activity, ranging from 16.37% to 26.44%. Additionally, all films containing SPE anthocyanins exhibited excellent UV barrier properties and demonstrated sensitivity to pH levels within the range of 1 to 10 in buffer solutions. Moreover, the films effectively preserved the freshness of the shrimp during storage. Consequently, these developed films showcase promising potential as active and intelligent packaging materials for food products.

“… Zhang, Zhang, Huang, Shi, Muhammad, Zhai, et al, 2023 ). The production of Intelligent films has been accomplished through the utilization of biologically active compounds, including curcumin, anthocyanins, and quercetin ( Hasan et al, 2024 , Subramanian et al, 2022 ). For example, preparation of blueberry anthocyanin film composite has been effective against pork spoilage ( Kong, et al, 2023 ).…”
