PROBLEM TO BE SOLVED: To provide a method which cleanly and easily, at a high yield, manufactures fresh fish with a transpired surface skin having excellent taste and texture without losing its original freshness, appearance, and taste by using fresh fish material or frozen fish material.SOLUTION: Processed products prepared by filleting and/or bone removal of a fish raw material 1 are placed on a raw material moving apparatus 11. A scanner 13 of a laser light irradiation device applies controlled continuous spot irradiation with laser light of a selective wavelength having excellent water absorption properties, to the whole skin surface of each of the processed product being moved, while scanning the skin surface in a direction crossing the direction of the moving. Thus, predetermined thermal energy is applied to the whole surface of the skin surface sequentially and uniformly, and only the skin surface is transpired without damage of the derma under the skin surface.COPYRIGHT: (C)2015,JPO&INPIT【課題】生鮮魚原料あるいは凍結魚原料を使用して、本来の鮮度や外観や味が維持され食味・食感に優れる表皮蒸散生鮮魚を衛生的に容易に高歩留まりで製造する方法の提供。【解決手段】魚原料1をフィーレ加工および/または骨取り加工して調製した加工品を原料移動装置11に載置し、移動する前記加工品に、レーザー光照射装置のスキャナ13によって、移動方向と交差する方向にスキャンしながら水分吸収性に優れる選択波長のレーザー光をその表皮全面に制御して連続的にスポット照射することによって表皮全面に順次均一に所定の熱エネルギーを供給し、前記表皮の下部の真皮を損なわずに、前記表皮のみを蒸散する。【選択図】図1
