Synthesis of Chitosan-Zirconium(IV) Complexes as an Antifungal Spraying Agent Against Tomato Infected Aspergillus Niger
Abstract
Chitosan has been extensively reported as a potent antimicrobial agent either alone or composited with other materials. Its activity against a wide range of food borne microbes and its chelating properties makes it a potential material for food crop preservation via complex formation. In this study, different ratios of chitosan-zirconium(IV) complexes (1:1, 2:1, 3:1) were prepared via co-precipitation method. The complexes were evaluated for the inhibition of the growth of Aspergillus niger in post harvested tomato fruits. Spectroscopic (FT-IR and UV-Vis) studies of the chitosan-zirconium(IV) complexes confirmed interactions between chitosan and zirconium metal ion. Chitosan coordinated to Zr4+ through –NH2 and –OH functional groups on its structure. Metal complex ratio 3:1 showed a higher antifungal activity compared to free chitosan on post harvested tomato fruits. Key words: Anti-fungi Actiity, Chitosan-Zirconium(IV) Complex, Tomato FruitDownloads
