本文对分子光谱法中最常用的红外光谱法、近红外光谱法、拉曼光谱法、紫外可见分光光度法、荧光光谱法以及超光谱成像技术等在食品(药品)安全领域的研究、应用、存在问题及发展前景等方面进行了综述。重点阐述了故意掺杂(比如保健品掺杂化学药品等)、无意残留(比如果蔬农药残留等)、其他物种混淆(比如他种药品冒充另一种化学药品等)三种情况下,采用光谱分析的特点和难点,尤其是这些分析对象对信息处理以及硬件设备的要求。在食品(药品)安全时代,需要分子光谱法大有作为,也大有可为。
In this paper, molecular spectroscopy in the most commonly used infrared spectroscopy, near infrared spectroscopy, Raman spectroscopy, UV-visible spectrophotometry, fluorescence spectroscopy and hyperspectral imaging technology in food (drug) safety research, application, Existing problems and development prospects are reviewed. In the three cases of deliberate doping (such as doping with chemicals, etc.), unintentional residues (such as pesticide residues in fruits, vegetables, etc.) and confusion of other species (for example, when another kind of medicine acts as another kind of chemical) Analysis of the characteristics and difficulties, especially the analysis of these objects on the information processing and hardware requirements. In the era of food (drug) safety, molecular spectroscopy needs a lot of work, but also promising.
