植物油种类及掺杂的荧光光谱鉴别研究

摘要

目的：探索荧光光谱法在食用植物油种类和掺杂鉴别中的可行性。方法采用荧光分析方法对棕榈油、芝麻油和菜籽油的掺杂进行鉴别。结果由于棕榈油、芝麻油和菜籽油的荧光光谱差异性明显，可以很好地区分棕榈油、芝麻油和菜籽油3种纯植物油。结论通过分析荧光光谱随掺杂浓度改变而产生的变换规律，达到对食用植物油的品质进行快速、准确的分析。荧光光谱法在食用植物油种类和掺杂鉴别中具有可行性。%Objective This study was to assess the feasibility of fluorescence spectroscopy for analysis in identification of palm oil,sesame oil and rapeseed oil. Methods Using fluorescence spectroscopy identified palm oil,sesame oil and rapeseed oil. Results The difference of fluorescence spectrum in palm oil,sesame oil and rapeseed oil is obvious,it can be easy to distinguish the three kinds of pure vegetable oil. Conclusion The quality of the edible vegetable oil was judged for rapid and accurate analysis by using fluorescence spectroscopy analysis with doping concentration change. Fluorescence spectroscopy analytical technological had feasibility in identification of adulterated edible vegetable oil.
