PROBLEM TO BE SOLVED: To provide a method for efficiently, in a short time, producing foods coagulated or sterilized by continuously heating a food material fluid using a simple apparatus easy to maintain, in particular, producing consistent-quality curd to be utilized as a material for various kinds of cheese from milk. SOLUTION: This method comprises the steps of continuously passing a food material fluid through the space between electrodes; heating the food material fluid with the Joule heat generated by applying a voltage to the electrodes to continuously coagulate or sterilize it. It is preferable that a flowing route for passing the food material fluid therethrough is arranged between the outer cylinder and inner cylinder of a double cylindrical tube, and the outer cylinder and the inner cylinder are each made to be an insulated electrode. It is favorable for producing the objective curd that the voltage to be applied is controlled so that the heated milk has the temperature of 40-80 deg.C, and milk to be passed through the space between electrodes is adjusted to <=10 deg.C and pH 4.8 to 5.8.
