The invention discloses a food deterioration detecting device with a voice broadcasting function. The food deterioration detecting device comprises a control module. The control module is respectively connected with a sensing module, a liquid crystal display module, a keyboard, a real-time clock module and a voice broadcasting module. The food deterioration detecting device has the advantages that the sensing module is used to detect the moisture, resistance and temperature of food, data offset can be well eliminated, temperature excursion and false detection can be reduced, the device is small in size, high in precision, good in stability, and the like, and the defect that a bacterial culture method for detecting the food is long in time and poor in portability is overcome; the device is multifunctional, can detect the resistance and moisture content of the food, and also has temperature measuring and timing functions; the measured data is digitally displayed through the liquid crystal display module accurately, and the device also provides the voice broadcasting function to allow elder people with poor eyesight to use the device conveniently.
