PROBLEM TO BE SOLVED: To provide a processed meat product obtained by a practical ultrasonic irradiation process capable of softening meat tissue without deteriorating surface of the meat, promoting increase of ingredients for excellent aged taste such as production of free amino acids, sufficiently creating the excellent aged tissue and taste in a short time by subjecting the meat to the ultrasonic irradiation process in ham manufacturing and aging process of meat. SOLUTION: This method uses a ultrasonic processing device provided with a rotary ultrasonic processing tank using a ultrasonic transducer as a fixed axis, a control section controlling frequency, output voltage, revolution of the rotary ultrasonic processing tank, irradiating time and a cooler for the rotary ultrasonic processing tank, subjects a raw meat or a curedmeat to the ultrasonic processing through a liquid accompanying generation of cavitations under an irradiating atmosphere of a combined oscillation of two or more frequencies of 10-100 kHz, output powers of 200-600 W, at 0-10 deg.C. |
