摘　　要：本研究将半胱氨酸–咔唑溶液与果糖溶液反应进行显色,采用紫外分光光度法评定了该显色反应的最佳显色条件,在此基础上,制作了比色卡。利用所确定的最佳显色条件和比色卡,可通过比色法实现市售饮料中果糖含量的便捷检测。该方法具有一定的应用前景,能够为果糖检测提供一种快速便捷的解决方案,为相关领域的研究和应用提供有力支持。In this study, the reaction of cysteine carbazole solution and fructose solution was carried out, and the optimal condition of the reaction was evaluated by UV spectrophotometry, on the basis of which, a colorimetric card was made. Under the optimum condition, the content of fructose in commercial beverages can be easily detected by colorimetry and colorimetric card. This method has a certain application prospect, because it can provide a quick and convenient solution for fructose detection, and provide strong support for research and application in related fields.
