Abstract
本发明属于香精香料分析检测，具体涉及一种基于全二维气相色谱‑质谱联用的香精香气指纹构建方法及应用，包括如下步骤：步骤1：对全二维GC×GC‑MS原始数据进行预处理；步骤2：香精特征呈香峰提取；步骤3：自动匹配与定性验证；步骤4：香气标签自动映射；步骤5：标准化香气指纹构建。与现有技术相比，本发明解决现有技术中香精的全二维GC×GC‑MS谱图的人工数据分析耗时长、识别能力弱，且精确度差，而现有分析方法难以适配香精测试分析的问题。本方案构建了一套针对于香精的全二维GC×GC‑MS全流程自动化解析方法，能够快速、准确的构建待测香精的标准化香气指纹，并可进一步用于香精领域中的检测、分析与判断。
