The invention discloses a reagent for detecting sulfite in food. The reagent is prepared from components in parts by weight as follows: 20-30 parts of a detection reagent, 30-55 parts of a solvent, 15-20 parts of a filling agent, 2-5 parts of a wetting agent and 3-6 parts of a disintegrating agent; the detection reagent is prepared from components in parts by weight as follows: 23-32 parts of 5,5'-dithio bis-(2-nitrobenzoic acid), 3-5 parts of sodium silicate, 1-3 parts of potassium stearate, 4-7 parts of polyethylene glycol and 0.1-1 part of vitamin E. With adoption of the detection reagent,concentration of sulfite in food can be rapidly detected, developing time is shortened, and detection efficiency is high; the reagent is not prone to deterioration in a transportation, storage or useprocess and is easy to store, long in shelf life, low in production cost and high in market popularization value, and large-scale production can be realized. 本发明公开了种用于检测食品中亚硫酸盐的试剂，所述试剂包括以下重量份数的组分：检测试剂20-30份、溶剂30-55份、填充剂15-20份、
