    • A method for inspecting an edible oil includes obtaining a first Raman spectrum from an edible oil sample, discovering an unhealthy, unsanitary, unsafe, or adulterated content in the edible oil sample in part by the intensity level of the fluorescence background in the first Raman spectrum, introducing the edible oil sample to nano-scale surface structures to allow molecules of the edible oil sample to be adsorbed to the nano-scale surface structures, illuminating the edible oil sample and the nano-scale surface structures by a laser beam, obtaining a second Raman spectrum from light scattered by molecules of the edible oil sample adsorbed to the nano-scale surface structures, and identifying the unhealthy, unsanitary, or unsafe content in the edible oil sample using one or more first spectral signatures in the second Raman spectrum.
    • 用于检查食用油的方法包括从食用油样品获得第一拉曼光谱,部分地发现食用油样品中不健康,不卫生,不安全或掺假的含量,部分由第一拉曼光谱中的荧光背景的强度水平 将食用油样品引入纳米级表面结构,使食用油样品的分子吸附到纳米级表面结构上,用激光束照射食用油样品和纳米级表面结构,得到 第二拉曼光谱从被吸收到纳米级表面结构的食用油样品的分子散射的光中,以及使用第二拉曼光谱中的一个或多个第一光谱特征识别食用油样品中的不健康,不卫生或不安全的含量。
