World health is increasingly threatened by the growing number of spice-related food hazards. Further development of reliable methods for rapid, non-targeted identification of counterfeit ingredients within the supply chain is needed. ENEA has developed a portable, user-friendly photoacoustic laser system for food fraud detection, based on a quantum cascade laser and multivariate calibration. Following a study on the authenticity of saffron, the instrument was challenged with a more elusive adulterant, olive leaves in oregano. The results show that the reported method of laser sensing and chemometric analysis was able to detect adulterants at mass ratios of at least 20% in less than five minutes.
世界健康正日益受到越来越多与香料相关的食品安全隐患的威胁。因此，需要进一步开发可靠的方法，以便在供应链中快速、非靶向地识别假冒成分。ENEA 开发了一种基于量子级联激光器和多元校准的便携式、用户友好的光声激光系统，用于食品欺诈检测。在对藏红花的真实性进行研究之后，该仪器又对更难检测的假冒物——奥利弗叶在牛至中的情况进行了测试。结果表明，该报告所提到的激光感应和化学计量分析方法能够在不到五分钟的时间内检测出至少 20%的掺杂物。
