Argan oil is one of the purest and rarest oils in the world, so that the addition of any further product is strictly prohibited by international regulations. Consequently, it is necessary to establish reliable analytical methods to ensure its authenticity. In this study, three multivariate approaches have been developed and validated using fluorescence, UV–visible, and attenuated total reflectance Fourier transform mid-infrared (FT-MIR) spectroscopies.

基于光谱传感器和化学计量学的三种指纹分析方法在摩洛哥坚果油掺假检测和定量中的比较研究

摩洛哥坚果油是世界上最纯净、最稀有的油之一，因此国际法规严格禁止添加任何其他产品。因此，有必要建立可靠的分析方法以确保其真实性。在这项研究中，使用荧光、紫外可见光和衰减全反射傅里叶变换中红外 (FT-MIR) 光谱开发并验证了三种多变量方法。
