Vegetable oil determining method

The invention discloses a vegetable oil determining method. A traditional vegetable oil determining method requires large sample size and long experiment period and is complicated in data processing. The method mainly aims to determine varieties of the vegetable oil more rapidly, visually and accurately without damage. The method adopts time-resolved fluorescence assay-fluorescence lifetime to determine the varieties of the vegetable oil, and comprises the following steps: step one, collecting a vegetable sample; step two, measuring a fluorescence quantum figure; step three, drawing fluorescence decay spectrum; step four, calculating the fluorescence service life. With the adoption of the method, a time-resolved fluorescence assay technology can be widely applied to the field of rapid analysis of quality of food and agricultural products containing complex fluorescence systems, the sensitivity is high, the test time is short, and the method is visual and accurate.
