The total samples consisted of ten fresh samples and seventy dehydrated samples of Day Lily. Assay followed the official method. This involves methods of testing for bleaching agents in food and testing for sulfur dioxide. This method has been published by Executive Yuan of the Department of Health.The results concluded that sulfide residues of ten samples of fresh Day Lily and eleven samples of dehydrated Day Lily, representing 15.7% of the total sample, corresponded with the regulation limit. The remaining fifty-nine samples, representing 84.3% of the total sample, detected illegal levels of residual sulfite (SO2). This level ranged from 1.26g/kg to 20.32g/kg.
