The botanical origin of honey attracts both commercial and research interest. Consumers’ preferences and medicinal uses of particular honey types drive the demand for the determination of their authenticity with regard to their botanical origin. This study presents the discrimination of thyme, multi-floral. and honeydew honeys by Fourier-transform infrared (FTIR) and ultraviolet (UV) absorption spectroscopy combined with multivariate statistical analysis. UV absorption spectroscopy was applied without any dilution of the sample using a custom-made cuvette. FTIR and UV absorption spectroscopic data were processed by means of the orthogonal partial least squares discriminant analysis.

光谱法结合多元统计分析对克里特百里香、多花蜜和蜜露的分类

蜂蜜的植物来源吸引了商业和研究兴趣。消费者对特定蜂蜜类型的偏好和药用需求推动了确定其植物来源真实性的需求。这项研究提出了百里香的鉴别，多花。通过傅里叶变换红外 (FTIR) 和紫外 (UV) 吸收光谱结合多元统计分析对蜜露蜂蜜进行分析。使用定制的比色皿在不稀释样品的情况下应用紫外吸收光谱。FTIR 和紫外吸收光谱数据通过正交偏最小二乘判别分析处理。
