阿魏酸改性明胶的性质变化研究

Effect of ferulic acid on the properties of gelatin

  • 摘要: 本文将不同浓度的阿魏酸用于明胶改性,用以研究其对明胶凝胶强度、流变性等主要性质的影响。利用凝胶强度检测、流变学分析、红外分析、X-射线衍射和扫描电镜分析法对明胶改性前后的性质做了分析比较。结果表明,阿魏酸可以提高明胶的凝胶强度和熔点。当阿魏酸总浓度为2.00 g/L时,明胶的凝胶强度得到明显提高。通过红外光谱的分析和X-射线衍射分析可以证实阿魏酸分子与不同的肽链交联,拉近了肽链之间的距离,使肽链间连接更紧密,而交联作用的主要作用力是氢键。本文研究表明,阿魏酸在特定浓度下可作为明胶良好的改性剂。 

     

    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.
