To provide a method for producing a processed scallop shell like a scallop shell prepared in a sealed packaged retort food form, a method of thawing a frozen scall muscle by heating and sterilizing by using an electric heating method is used, And to provide a method for producing a processed product of a mantis with good color taste and taste and texture while preventing browning, taste and texture deterioration due to electric heating and sterilization treatment.SOLUTION:Upon thawing the frozen scall milk and subjecting it to heat sterilization treatment, the frozen scall muscle was immersed in a saline solution having a salt concentration range of 1 w / v% or more and less than 7 w / v% in thawing treatment at the time of manufacturing a sterilized scalloped work product After that, sterilization treatment is applied using electric current heating, thereby manufacturing a sterilized processed scallop shell product which is prevented or inhibited from browning and has a good texture. The method for producing a marinated meat processed food of the present invention can be applied to aseptic packaging such as a heat sterilization treatment or aseptic filling after heat sterilization treatment, and can be provided as a scalloped item that can circulate at room temperature.Selection drawing None【課題】密封包装されたレトルト食品形態で調製されるホタテガイ貝柱のような貝柱加工品を製造する方法として、冷凍貝柱を解凍及び通電加熱を用いて加熱殺菌を行う方法を用い、かつ、該解凍及び通電加熱殺菌処理による褐変及び食味・食感の低下を防止して、色調及び食味・食感の良い、貝柱加工品を製造する方法を提供すること。【解決手段】冷凍貝柱を解凍後、加熱殺菌処理することにより、殺菌済貝柱加工品を製造するに際して、冷凍貝柱を1w/v%以上7w/v%未満の食塩濃度範囲の食塩水溶液に浸漬して解凍処理した後、通電加熱を用いて殺菌処理を施すことにより、褐変が防止若しくは抑制され、かつ、食感の良い殺菌済貝柱加工品を製造する。本発明の貝柱加工食品の製造方法は、加熱殺菌処理、或いは加熱殺菌処理後のアセプティック充填等の無菌包装に適用することができ、常温で流通可能な貝柱商品として提供することができる。【選択図】なし
