Fish is extremely perishable as a result of rapid microbial growth naturally present in fish or from contamination. Synthetic preservatives are widely used in fish storage to extend shelf life and maintain quality and safety. However, consumer preferences for natural preservatives and concerns about the safety of synthetic preservatives have prompted the food industry to search natural preservatives. Natural preservatives from microorganisms, plants, and animals have been shown potential in replacing the chemical antimicrobials. Bacteriocins and organic acids from bacteria showed good antimicrobial activities against spoilage bacteria. Plant-derived antimicrobials could prolong fish shelf life and decrease lipid oxidation. Animal-derived antimicrobials also have good antimicrobial activities; however, their allergen risk should be paid attention. Moreover, some algae and mushroom species can also provide a potential source of new natural preservatives. Obviously, the natural preservatives could perform better in fish storage by combining with other hurdles such as non-thermal sterilization processing, modified atmosphere packaging, edible films and coatings.

“…The Fang group developed a novel electrochemical impedance sensor that utilized alginate/GO hydrogels for the encapsulation of rat basophilic leukemia mast cells (RBL-2H3) on MWCNs. 157 Binding of P. aeruginosa -produced 3OC 12 -HSLs to the immobilized mast cells triggered degranulation of secretory vesicles containing inflammatory mediators, which resulted in a significant decrease in cell viability and an increased electron transfer rate at the working electrode. Notably, the use of MWCN-modified screen-printed carbon electrodes (SPCEs) over traditional electrodes warranted a lower-cost, disposable device with improved electrochemical sensitivity and stability.…”

“…Bare screen-printed electrodes were stabilized using cyclic voltammetry, then MWCNTs were drop-casted from aqueous suspension and dried in nitrogen stream. A cell suspension was deposited on the surface of the screenprinted electrodes modified with MWCNTs and covered with a hydrogel based on sodium alginate and graphene oxide, at 37 C for 5 min and conditioned in CaCl 2buffered DMEM medium for 5 min in 37 C. The morphology of the cells was revealed using scanning electron microscopy tests performed for native RBL cells (Jiang et al 2018). Copyright (2018) Elsevier) ( Fig.…”
