[目的]应用化学快检定性法检测发酵乳中蔗糖,开发一种基于显色反应的快速筛查方法。[方法]通过与高效液相色谱法（HPLC）对比,验证本研究方法在检测限（0.2 g/100 g）以上的准确性（r=0.98,P<0.01）。[结果]化学快检定性法相较HPLC的检测时间从5 h缩短至10 min,单次检测成本降低80%,且对零蔗糖样品（n=50）的检测结果与HPLC一致性达96%。[结论]该方法操作简便、快速,适用于生产线实时监测,可为乳品企业提供高效、低成本的蔗糖检测方案,并可作为检测零蔗糖发酵乳的有效方法进行推广。

[Objective]To detect sucrose in fermented milk by chemical rapid qualitative detection method and develop a rapid screening method based on color reaction.[Method]By comparing with high performance liquid chromatography（HPLC）,the accuracy of this method above the detection limit（0.2 g/100 g） was verified（r=0.98,P<0.01）.[Result]Compared with HPLC,the detection time of the chemical rapid qualitative detection method was shortened from 5 hours to 10 minutes,the single detection cost was reduced by 80%,and the consistency of the detection results of zero-sucrose samples（n=50）with HPLC reached 96%.This method is simple to operate and can complete the detection in just 10 minutes,making it suitable for real-time monitoring on production lines,providing a high-efficiency and low-cost sucrose detection solution for dairy enterprises.It can be promoted and used as an effective method for zero-sucrose detection in fermented milk.[Conclusion] This method is simple and rapid to operate, suitable for real-time monitoring of production lines. It can provide dairy enterprises with an efficient and low-cost sucrose detection solution and can be promoted as an effective method for detecting zero-sucrose fermented milk.
