利用FTIR技术结合2D-IR技术对病害苹果进行鉴别研究。原始红外光谱趋势类似,由糖类、蛋白质以及酚类等组成。导数光谱在1800cm~(-1)至700cm~(-1)区域差别较大,并利用软件在该区域进行分析,发现病变果与相对于正常果蛋白质以及糖的含量发生变化。2D-IR在1020-1至1140cm~(-1)以及1400-1至1710cm~(-1)范围内,苹果的吸收峰(自动峰、交叉峰)的强度和位置有较大的差异,也可分析出蛋白质以及糖类发生变化。结果表明:应用FTIE技术结合2D-IR技术可以快速有效鉴别出病变果与正常果的区别。
Using FTIR technology combined with 2D-IR technology to identify the disease apple. The original infrared spectrum similar trends, from sugar, protein and phenols and other components. Derivative spectra vary greatly in the 1800 cm -1 to 700 cm -1 region and software was used to analyze in this region and the content of diseased fruit relative to normal fruit protein and sugar was changed. In the range of 1020-1 to 1140 cm -1 and 1400-1 to 1710 cm -1, the intensities and positions of 2D-IR absorption peaks (auto-peaks and cross-peaks) of 2D-IR were also significantly different. Can analyze the protein and carbohydrate changes. The results show that the application of FTIE combined with 2D-IR technology can quickly and effectively identify the difference between diseased and normal fruit.
