Title: Determination of Illegal Cooking Oil Mixed with Blend Oil
Abstract: The three-dimensional fluorescence spectrometry was used to detect a spot of illegal cooking oil mixed in blend oil,which was proved successful.Through the experiment,conclusions were obtained as follows:when volume ratio of added illegal cooking oil exceeded 5%,relative fluorescence intensity decreased to 2533 in Ex=310nm,Em=345nm,and relative fluorescence intensity fell by 2872 comparing with fresh blend oil,that could be a criterion to confirm whether a blend oil mixed with illegal cooking oil.This method is sensitive and stable,and suitable for detection little illegal cooking oil mixed with blend oil.
