Abstract
A heating apparatus such as microwave ovens includes a heater heating food contained in a cooking chamber and a temperature sensor sensing the temperature in the cooking chamber. An initial temperature is detected at an initial stage of the cooking on the basis of the temperature sensed by the temperature sensor. An intermediate temperature is further detected a predetermined time period after the start of the cooking. Based on the difference between the detected initial and intermediate temperatures, a suitable cooking period of time is determined.
