A green nanocomposite film with pH-sensitivity and antioxidant activity based on oxidized chitin nanocrystals (O-ChNCs)/gelatin incorporating black rice bran anthocyanins (BACNs) was prepared in this study. Fourier transform infrared spectrum showed that BACNs were successfully immobilized into the O-ChNCs/gelatin matrix through non-covalent bonds. Scanning electron microscopy and atomic force microscope showed that BACNs was uniformly distributed in the O-ChNCs/gelatin matrix. Although the incorporation of BACNs decreased the mechanical properties of the films, it endowed the films with excellent UV-vis light barrier and antioxidant character. Moreover, the O-ChNCs/gelatin/BACNs films were pH-sensitive and showed remarkable color changes in different buffer solutions, which could be used to monitor the freshness of shrimp and hairtail by visible color changes. The colorimetric films with lower content of BACNs were found more sensitive toward basic volatile amines emitted during storage. Therefore, the developed O-ChNCs/gelatin/BACNs films may have a great potential in the freshness monitoring of high protein foods.

This study introduces an innovative bio-based sorbent bead crafted by integrating chitosan (CS) biopolymers, Fe(NO3)3 and polydopamine nanoparticles (PDA NPs) via glutaraldehyde crosslinking. The primary focus of this study was the concurrent separation of diverse tetracycline antibiotics (TCs), followed by rigorous reversed-phase liquid chromatography analysis. The fabricated CS/Fe@PDA sorbent beads were comprehensively characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy, revealing a surface rich in active carbon (C), nitrogen (N), and oxygen (O) moieties.

Renal ischemia-reperfusion (I/R) injury is a common clinical factor for acute kidney injury (AKI). A current study investigated the renoprotective effects of the trinitroglycerine (TNG) combination with chitosan nanoparticles (CNPs) on renal I/R-induced AKI. Rats were randomly assigned to five groups (n = 8/group): Sham, I/R, TNG (50 mg/kg) + I/R, CNPs (60 mg/kg) + I/R, and TNG-CNPs + I/R.

In this study, the nano chitosan particles were produced by ionotropic gelation between sodium tripolyphosphate and chitosan. The effect of nano chitosan with or without sodium lactate coating was evaluated on physicochemical (pH, thiobarbituric acid, total volatile basic nitrogen, and peroxide), microbial (total mesophilic and psychrotrophic viable counts, lactic acid bacteria, yeasts, and molds), and sensorial properties of beef burgers within 24 days of storage at 4°C. The solutions of 1% nano chitosan (T), 2% nano chitosan (T), 2.
