The aim of this study was to develop a simple indicator that can be solved at room temperature and that warns of rising temperature in food production. The indicator was prepared by mixing red cabbage dye with sodium hydrogen carbonate, sodium carbonate and lactose and applied to food production. The indicator changed color after 36 hours at 12℃, after 48 hours at 10℃, after 96 hours at 4℃ and after 88 hours at varying temperature. The time required to change color varied depending on the concentration of red cabbage dye.
