Applicable to industrial manufacturing of slurry which can stably produce frozen slurry which is excellent in freezing storage property and hardly lowered in gel forming ability during freezing storage when fish meat ingredients mixed with viscera are used , A practical and highly productive production method, and a frozen sperm produced by the method. In the production of the sewing using the fish meat raw material mixed with the viscera, in particular the kidney which is difficult to remove in manufacturing, it is preferable to add a basic addition having no chelating action other than sugar and sugar alcohol, polymerized phosphate, polymerized phosphate And adjust the pH of the warp to 7.5 or more with a basic additive having no chelating action other than the polymerized phosphate and the polymerized phosphate.内臓が混入した魚肉原料を用いた場合において、凍結貯蔵性に優れ、凍結貯蔵中のゲル形成能の低下が生じにくい冷凍すりみを安定的に製造できる、工業的なすりみ製造にも適用可能な、実用的で生産性が高い生産方法、及び、その方法で生産された冷凍すりみを提供する。 内臓、特に製造上除去が難しい腎臓が混入した魚肉原料を用いてすりみを製造する際に、糖及び糖アルコール、重合リン酸塩、重合リン酸塩以外のキレート作用を有さない塩基性添加物を混合し、かつ、すりみのpHを重合リン酸塩と重合リン酸塩以外のキレート作用を有さない塩基性添加物で7.5以上に調整する。
