|Title||REAGENT KIT FOR MEASURING FRESHNESS|
A reagent kit for measuring freshness with high storage stability at a relatively high temperature is obtained by lyophilizing reagent solutions each containing a plurality of enzymes and an enzyme protective agent. The reagent kit contains a first reagent and a second reagent. The first reagent is obtained by drying a frozen matter of a first reagent solution containing XOD, NP, an enzyme protective agent, and a color-forming agent under reduced pressure at a temperature not higher than the glass transition point temperature (Tg). The second reagent is obtained by drying a frozen matter of a second reagent solution containing XOD, NP, AP, an enzyme protective agent, and a color-forming agent under reduced pressure at a temperature not higher than the glass transition point temperature (Tg). The enzyme protective agent contains sucrose and/or gelatin. The color-forming agent contains a substance which forms color by being coupled to degradation of Hx into xanthine and uric acid by XOD.
