Saffron ( L.), an exceptionally valuable and expensive spice on an international scale, has become the target of a rapid increase in fraudulent practices. In an effort to decrease expenses, stigmas of safflower (), which closely resemble saffron, are often added to pure saffron as a typical method of adulteration. Hence, by quantifying the extent of eugenol modifications in the samples and employing ion mobility spectrometry (IMS) to identify and quantify these adulterants in saffron, the objective of this research has been accomplished. The analysis of eugenol showed a significant increase in peak intensity as the concentration of safflower increased in laboratory-prepared samples of pure saffron and safflower as well as the mixture of them (25%, 50%, 75%, and 100%, v/v). In the subsequent phase, a total of 20 saffron samples procured from nearby markets were examined under an optical microscope to identify any adulteration with safflower. Five samples, which included saffron containing safflower at varying concentrations (8.3%, 14.9%, 19.4%, 25.4%, and 33.7% W/W), were chosen for additional IMS analysis. The results showed that the peak intensity of eugenol climbed from 0.20 to 0.28 mV by augmenting the safflower content in saffron. Therefore, by increasing the level of safflower contamination in saffron, the concentration of eugenol in the IMS rose. The outcomes demonstrated that the selection method effectively detects saffron adulterated with safflower, improving both precision and specificity, and could aid in defining standard quality control procedures for saffron authenticity and quality.
藏红花(Crocus sativus L.)是一种在国际上极为珍贵且昂贵的香料,已成为欺诈行为迅速增加的目标。为了降低成本,常将与藏红花极为相似的红花(Carthamus tinctorius)柱头添加到纯藏红花中作为典型的掺假方法。因此,通过量化样品中丁香酚修饰的程度,并采用离子迁移谱(IMS)来鉴定和量化藏红花中的这些掺假物,本研究的目标得以实现。对丁香酚的分析表明,在实验室制备的纯藏红花和红花样品以及它们的混合物(25%、50%、75%和100%,v/v)中,随着红花浓度的增加,峰强度显著增加。在随后的阶段,对从附近市场采购的总共20个藏红花样品在光学显微镜下进行检查,以确定是否掺有红花。选择了五个样品,其中包括含有不同浓度红花(8.3%、14.9%、19.4%、25.4%和33.7% W/W)的藏红花,进行额外的IMS分析。结果表明,通过增加藏红花中红花的含量,丁香酚的峰强度从0.20mV攀升至0.28 mV。因此,随着藏红花中红花污染水平的增加,IMS中丁香酚的浓度上升。结果表明,该选择方法能有效检测出掺有红花的藏红花,提高了精度和特异性,有助于确定藏红花真伪和质量的标准质量控制程序。
