PROBLEM TO BE SOLVED: To provide a method for producing acidic gel-state food containing protein and/or protein hydrolysate, which has good workability even when producing a large amount of food, has no problem of causing unevenness in the gelling strength of the product obtained, and is reduced in the blending quantity of a stabilizer or a gelling agent such as soybean polysaccharide.SOLUTION: The method for producing the acidic gel-state food comprises: dispersing protein and/or protein hydrolysate in aqueous solution via a dispersion means having shearing force until the median diameter of the volume distribution of the dispersed particles becomes 0.1-10 &mum, adding the stabilizer to the mixture and further mixing them together to obtain raw material (A) mixing the raw material (A) with raw material B obtained by dissolving a Gellan gum-containing gelling agent with heat and thereafter cooling the dissolved mixture to be gelatinized.COPYRIGHT: (C)2010,JPO&INPIT【課題】タンパク質及び/又はタンパク加水分解物を含有する酸性ゲル状食品の製造方法であって、大容量に製造する場合であっても、作業性よく、得られる製品のゲル強度にバラツキが生じてしまうという問題がなく、大豆多糖類等の安定剤やゲル化剤の配合量も減らせる、該酸性ゲル状食品の製造方法を提供する。【解決手段】タンパク質及び/又はタンパク加水分解物を剪断力のある分散手段で、分散粒子の体積分布のメジアン径が0.1~10μmになるまで水性液中に分散し、安定剤を加えてさらに混合して原料Aを得、これとジェランガムを含むゲル化剤を加熱溶解した原料Bを混合して、その後、冷却してゲル化する。【選択図】 なし
