| 摘 要： | 分析了新疆产8种干果的红外光谱特征。这8种干果可分为两类，其红外图谱在官能团区有很大差异。巴旦木、核桃仁、花生仁、带壳杏仁富含蛋白质和脂类物质，红外图谱显示出在2914，2847cm^-1附近的CH伸缩振动和1742cm^-1附近的C=O伸缩振动；枸杞子、红枣、葡萄干和无花果干富含多糖、蛋白类物质，其红外图谱显示出在3370cm^-1附近的OH变形振动、NH伸缩振动和2920cm^-1附近的CH伸缩振动。

| Abstract: | The infrared spectral characteristics of eight dried fruits were analyzed and the results showed that those dried fruits could be divided into two groups with significant difference infrared spectrum in functional groups.Almond,walnut,peanut and almond are abundant in protein and lipid with CH stretching vibration nearby 2 914 cm-1,2 847 cm-1and C=O stretching vibration nearby 1 742 cm-1 in their infrared spectrum;while wolfberry fruit, red date,raisin and fig are abundant in pdysaccharide and protein content.Infrared spectral shows OH deformation vibration nearby 3 370 cm-1and NH stretching vibration and CH stretching vibration nearby 2 920 cm-1. |
