WebChitin is soluble in 5% lithium chloride/N,N-dimethylacetamide solvent [LiCI/DMAc] and insoluble in aqueous acetic acid while the opposite is true of chitosan. The nitrogen content in purified samp les is less than 7% for chitin and more than 7% for chitosan (Dash et al., 2011; Rinaudo, 2006). Fig. 1. Chemical structure of chitin and chitosan. WebThe well compatibility of chitin nanoparticles with gelatin polymer was concluded from Fourier transform infrared (FTIR) spectra and X-ray diffraction (XRD) plots. Finally, the gelatin based nanocomposite films had anti-fungal properties against Aspergillus niger in the contact surface zone.
