Abstract: Ferulic acid was added to gelatin,and the changes in the gelatin were characterized to determine the effect of ferulic acid modification. The microstructural changes in the samples were analyzed using Fourier transform infrared spectroscopy( FTIR),X- ray diffraction( XRD),and scanning electron microscopy( SEM). The results indicated that the gel strength and thermal stability of gelatin could be improved by appropriate ferulic acid addition.The gel strength of gelatin was obviously improved when the concentration of ferulic acid was 2.00 g / L.The result was also verified hydrogen bonds were the main molecular interactions observed in the ferulic acid- gelatin samples using FTIR and XRD.The study showed that certain concentration of ferulic acid could be a good modifier of gelatin.
