Summary

BLOCKS OF PACIFIC COD (GADUS MACROCEPHALUS) WERE THAWED IN A 291 K (18 DEG C) CIRCULATED WATER BATH AND SIMULTANEOUSLY EXPOSED TO 1,500 HZ ACOUSTIC ENERGY NOT EXCEEDING 60 WATTS. A CERAMIC TRANSDUCER WAS POSITIONED FOR LIGHT CONTACT WITH A FROZEN BLOCK. A MOTORIZED BELT MOVED THE BLOCK. AT 60 WATTS CONTINUOUS INPUT TO THE TRANSDUCER, THE BLOCK THAWED IN 71% LESS TIME THAN WATER-ONLY CONTROLS. QUALITY ANALYSES INDICATED THAT THE FLESH WAS NOT ADVERSELY AFFECTED BY THE ACOUSTIC WAVES.
