To provide an ultrasound food processing method and an ultrasound food processing apparatus with excellent productivity capable of easily preparing pickles in a short time using ultrasound.SOLUTION: The ultrasound food processing apparatus 1 of this invention comprises: a liquid tank 2 that houses and holds a food material 10 being a processing object and a liquid 11 in which the food material 10 is immersed; an ultrasound transducer 3 that is disposed in the liquid tank 2 and radiates ultrasound to the liquid 11; and an ultrasound oscillator 4 that is connected to the ultrasound transducer 3 and supplies power for the ultrasound to the ultrasound transducer 3. The ultrasound food processing method includes: placing the food material 10 being the processing object into the liquid tank 2 to immerse the food material into the liquid 11 that is a seasoning liquid; and radiating the ultrasound to the liquid 11. Thereby it is possible to favorably change a cell membrane structure of the food material 10 by the ultrasound radiated into the seasoning liquid and promote drainage of water from the food material 10 and permeation of seasoning components. Accordingly, it is possible to prepare good-flavored pickles in a short time with an easy processing operation.SELECTED DRAWING: Figure 1 【課題】超音波を利用して短時間で容易に漬物を加工することができる生産性に優れた超音波食品加工方法及び超音波食品加工装置を提供する。【解決手段】超音波食品加工装置１は、加工対象の食品材料１０とその食品材料１０が浸漬される液体１１とが入れられる液体槽２と、液体槽２に設けられて液体１１に超音波を放射する超音波振動子３と、超音波振動子３に接続され超音波振動子３に超音波の電力を供給する超音波発振器４と、を有する。超音波食品加工方法は、加工対象の食品材料１０を液体槽２に入れて調味液である液体１１に浸漬し、液体１１に超音波を放射する。これにより、調味液中に放射された超音波によって食品材料１０の細胞膜構造を好適に変化させ、食品材料１０の水抜きや調味成分の浸透を促進することができる。よって、容易な加工作業によって、風味の良い漬物を短時間で得ることができる。【選択図】図１
