Food is treated with ultrasound so that indigestible bones are altered to a condition for conveniently removing the bones, making the food suitable for consumption. A bone weakening or bone disintegrating effect is applied to fish bones by the application of the technique of extracorporeal shock wave lithotripsy. High pressure shock waves pass through the flesh of the fish so that either the resulting disintegrated bone material is present as particulate matter which can be filtered from the flesh of the fish, or the flesh of the fish can be subsequently separated from the bones. A fish deboning apparatus 1 is comprises a receptacle for receiving the fish and surrounding with water, before the application of ultrasonic waves from above. Other methods involving the use of ultrasound in the treatment of deposits in appliances and pipe systems are described. |
