Pararosaniline was the most accurate and sensitive method of determining SO2 residue, and it was fit for the samples of any SO2 content. Improvement pararosaniline method was only fit for the samples of high SO2 residue. Iodometry was not fit for the deep color samples and low SO2 residue samples. The fast determination method could be used the quality and semi-quantitative determination of SO2 residue in edible fungus.

副玫瑰苯胺比色法是检测SO2残留最准确、最灵敏的方法，适合于各种SO2浓度的样品；改良的副玫瑰苯胺比色法只适合于高SO2残留的样品；碘量法不适宜检测深颜色的食用菌，而且在检测低SO2残留样品时准确度不高；快速测定法可用于食用菌产品中SO2残留的定性检测和半定量分析。
