摘要
白茶的鉴别主要依靠感官评价和质谱方法,存在主观性强、分析复杂等缺点。因此,本研究建立了一种基于比色指示剂位移测定(IDA)传感器的新方法,以实现快速准确的白茶鉴别。本研究选择了性价比高的染料和不同取代基的苯硼酸分别作为指示剂和受体。构建了一个颜色信号响应的 IDA 传感器阵列,以实现对白茶的快速灵敏识别。此外,还使用了三种监督模式识别算法来处理图像数据。结果表明,将 IDA 传感器与随机森林算法相结合,能准确区分白茶样品的产地和类型,当 ntree = 1000 时,训练集(n = 84)和预测集(n = 56)的识别准确率均达到 100%。这项工作为快速识别白茶产品提供了一种经济高效的方法。
Rapid identification of white tea based on colorimetric indicator displacement assay (IDA) sensor array
The identification of white tea mainly relies on sensory evaluation and mass spectrometry methods, which have drawbacks such as strong subjectivity and complex analysis. Thus, this study established a novel approach based on colorimetric indicator displacement assay (IDA) sensor to achieve rapid and accurate white tea identification. Cost-effective dyes and phenylboronic acids with different substituents were selected as the indicator and receptor, respectively. A color-signal-responsive IDA sensor array was constructed to enable the rapid and sensitive identification of white tea. Additionally, three supervised pattern recognition algorithms were utilized to process image data. The results demonstrate that combining the IDA sensor with the random forest algorithm accurately differentiates white tea samples by origin and type, achieving a 100% recognition accuracy in both training set (n = 84) and prediction set (n = 56) when ntree = 1000. This work offers an economical and efficient method for the rapid identification of white tea products.
