摘要
目的:对食品中的吊白块进行检测。方法:盐酸苯肼法定量甲醛,醋酸铅试纸法半定量二氧化硫和硫化氢,再综合考虑两种方法的检测结果来判断食品中吊白块的存在与否。结果:该方法简便、快速、灵敏度高、稳定性好。结论:此方法适用于所有食品中吊白块的检测。
Objective： To test sodium formaldehyde sulfoxylate in food. Methods： HCHO was tested by phenyldrazine hydrochoride spectrophotometer and SO2 and H2S were tested by lead （Ⅱ ） acetate paper. Two methods were compared in detecting sodium formaldehyde sulfoxylate in food. Results： The method was simple, quick, highly sensitive and stable. Conclusion： The method can be used to test sodium formaldehyde sulfoxylate in all foods.
