CONSTITUTION:Ultrasonic wave having <=100KHz (preferably 10-40KHz) frequency is applied to fishes and shellfishes kept in frozen state or semi-frozen state of <=5 deg.C (preferably -5 to +5 deg.C) to carry out the objective treatment. Furthermore, the ultrasonic treatment can effectively be carried out by previously applying edible oil and fat and/or seasoning to the fishes and shellfishes and making preparations before the treatment. |
