In this paper, SDS-PAGE electrophoresis and fluorescence spectroscopy were used to analysis Chinese date honey (CDH) protein. It is shown that there were significant differences on protein content of CDH from different areas. For example, the protein content of CDH in Jiaxian was the highest (1468.18 μg/g), whereas that in Fuping was the lowest (719.03 μg/g). The main protein bands of CDH in different areas in Shaanxi were little difference. However, the protein bands of CDH from different province showed highly significant difference, with specific protein bands. Meanwhile, the maximum peak and intensity of CDH protein fluorescence from difference areas have signifi- cant differences, indicating significant differences on protein composition and structure of CDH.%以枣花蜜为试材,分析了不同产地的枣花蜜蛋白质的电泳行为及其荧光光谱特征。结果表明:不同地区枣花蜜的蛋白质含量存在明显差异,在供试样品中陕西佳县蛋白质含量最高(1468.18μg/g),而富平蛋白质含量最低(719.03μg/g);SDS—PAGE分析发现,陕西省不同地区枣花蜜蛋白质主要电泳谱带差异不大,但不同省份的枣花蜜蛋白质电泳谱带差异较大,表现出特有的蛋白质谱带;荧光光谱分析发现,不同地区枣花蜜蛋白质的最大荧光吸收峰和强度存在明显差异,说明枣花蜜蛋白质组成和结构存在一定的差异。
