An ultrasonic treatment during extraction with hot water was investigated as a new procedure for preparing chicken-bone soup stock. The relationship between the preference and the soluble components of the chicken soup stock was studied to determine the most appropriate conditions for the preparation method. Compared to the conventional method without an ultrasonic treatment, the time for extraction was reduced to one third by the ultrasonic treatment, and a high-quality soup was obtained from chicken-bones. The combined method was thus found to be more suitable for preparing the soup stock. The best conditions for preparing the chicken soup stock with 20% bone involved hot-water extraction at 98℃ accompanying the ultrasonic treatment for 30 min. The resulting color tone of the soup was light with and slight clouding, and the dissolved components, including 5'-IMP, crude proteins, and free amino acids such as Glu, Ala, Ser and Gly were rich in the soup. A high evaluation of the resulting soup was given. (Received April 9, 1996)
