Two novel click derived sensory systems for different derivatives connected via a triazole linkage have been developed as a component of a chemosensor with sensitive towards Fe ions. The 1-octyl-4-carboxyl-1,2,3-triazole (TR1) system demonstrated sensitivity to calcium ion. The 1,3-bis(4-hydroxycarbamoyl-1,2,3-triazol-1-yl)xylylene (TR2) system was shown to possess a preferential detection capability as a colorimetric probe for Fe ions by exhibiting an obvious pH-dependent color change from colorless to pink. Complexation of the ligands with Fe ions was studied. The 1:1 stoichiometry and bonding sites of TR1Fe, and TR2Fe complexes were elucidated by analyzing the Job plot. The association constants of 5.35 × 10 M for TR1 Fe and 3.58 × 10 M for TR2Fe and detection limits 1.68 × 10 and 2.52 × 10 were determined from standard deviation and linear fittings.

Residual nitrite (NO) and nitrate (NO) have been widely studied in the past few decades for their function to improve processed meat quality and their impact on human health. In this study we examined how the residual nitrite and nitrate (NO) content of major classes of processed meats products (n = 1132) produced locally from three regions (East Coast, Midwest and West Coast) and plant protein-based meat analogues (n = 53) available at retail in the United States was influenced by their composition, processing, and geographical attributes. We also conducted time-dependent depletion studies and observed different patterns of NO depletion and conversion during processing and storage and correlated them with product quality.

The ternary complex effectively prevents droplet aggregation, Ostwald ripening, and phase separation through its gel network, thereby demonstrating its capability in bioactive compound delivery. In this work, the influence of varying chickpea protein isolate (CPI) levels on the microstructure, gel characteristics, stability and functional properties of grape seed proanthocyanidin (GSP) and konjac gum (KGM) stabilized ternary complexes was investigated. Visual appearance indicated the formation of a non-stratified ternary complex as the CPI enhanced to 3-4 %.
