Active films from water-soluble chitosan/cellulose composites incorporating releasable caffeic acid for inhibition of lipid oxidation in fish oil emulsions

Development and Characterization of an Active Chitosan-Based Film Containing Quercetin

“…Spoilage and contamination by microorganisms and oxidation processes are responsible for the loss of quality and reduction of food safety, e.g., by triggering unpleasant tastes and odors, discoloration, and acting in the formation of harmful compounds during storage and sales (Yu et al 2013;Martins et al 2012;Dutta et al 2009). …”

New supramolecular metallo-terpyridine carboxymethyl cellulose derivatives with antimicrobial properties

“…Different routes have been studied to impart CMC antimicrobial properties, such as: the addition of antimicrobial agents (Liu, Han, Zhang, Li, & Li, 2012;Ng & Jumaat, 2014;Sayanjali, Ghanbarzadeh, & Ghiassifar, 2011); metal nanoparticles (Hebeish, Hashem, El-Hady, & Sharaf, 2013;Malmiri, Tan, Rahman, & Osman, 2013;Percival et al, 2012;Valappil et al, 2013;Zhong, Oporto, Jaczynski, Tesfai, & Armstrong, 2013), antimicrobial polymers (Yu et al, 2013); and grafting with other moieties possessing antimicrobial activity (El-Sherbiny, Salama, & Sarhan, 2009). Terpyridines are N-heterocycles that exhibit high binding affinity toward transition metal ions due to strong d-p* backbonding of the metal to the pyridine rings and the chelate effect. These terpyridine metal complexes possess distinct photophysical, electrochemical, and magnetic properties and have been widely investigated (Schubert, Winter, & Newkome, 2011).…”

Fabrication, characterization and determination of biological activities of poly(ε-caprolactone)/chitosan-caffeic acid composite fibrous mat for wound dressing application

“…Gram-negative bacterial (S. aureus) cell walls, which exhibit greater hydrophilicity and negative charge on the cell surface compared with Gram-positive (E. coli) cell walls, show a stronger interaction with chitosan than the Gram-positive bacteria [51]. Moreover, previous studies reported that some polyphenols of the hydroxycinnamate group, including caffeic acid can inhibit the growth of bacteria such as E. coli, S. aureus, and some yeasts [52,53]. The anti-microbial action of these phenolic compounds is related to their ability to denature proteins, and these compounds are classified as surface-active agents [54].…”
