There are many methods for testing sulfur dioxide in food, nonetheless, not many studies have been done on the comparison with published test methods. Many screening methods have been produced in order to quickly test sulfur dioxide residues in dehydrated daylily products. The purpose of this study was to examine residual amount of sulfur dioxide in daylily from different origin, comparing and contrasting them with the recommended and published test methods; which were the ＂method of test for sulfur dioxide in foods (GC/MS method)＂ and two quick screening methods, namely; ＂Merck sulfite test＂ and ＂modular aeration distillation system＂. The correlation coefficient (r value) of the test results of the Merck sulfite test method in the high mountain daylily and the published test method, indicated low correlation. The other test methods were all significantly correlated, and the correlation coefficients were between 0.8469 - 0.9812. In addition, the correlation coefficients of the comparison of the difference between the above two quick screening methods for plain ground and high mountain daylily test results were 0.9269 and 0.5354, respectively. Although the quick screening inspection method has its limitations, it can still be used as a reference for independent management of processing sites and on-site inspection of law enforcement officials.
