PROBLEM TO BE SOLVED: To provide a method capable of manufacturing concentrated fermented milk containing a food raw material (for example, dry mango which absorbs water and swells) with a simple method and at low cost without using specific facility.SOLUTION: There is provided a manufacturing method of concentrated fermented milk containing a water absorptive raw material including (A) a high Brix liquid impregnation process for impregnating edible solid water absorptive raw material into a high Brix liquid having large Brix value at a level with which the water absorptive raw material does not absorb water or keeps water absorptive performance thereof to obtain high Brix liquid containing the water absorptive raw material, and (B) a water penetration process for mixing the high Brix liquid containing the water absorptive raw material obtained in the process (A), and a fermented milk mix before fermentation or fermented milk after fermentation, then leaving the resulting fermented milk mix or fermented milk containing the water absorptive raw material, and making moisture contained in the fermented milk mix or the fermented milk penetrate into the water absorptive raw material to obtain the concentrated fermented milk mix or the concentrated fermented milk containing water absorbed water absorptive raw material.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】特殊な設備を用いなくても、簡易な方法でかつ低コストで、食品素材(例えば、ドライマンゴーが吸水して膨潤したもの)入りの濃厚発酵乳を製造することができる方法を提供する。【解決手段】(A)食用可能な固形の吸水素材を、該吸水素材が吸水しない、あるいはその吸水能力を維持しうる程度に大きなブリックス値を有する高ブリックス液中に浸漬して、吸水素材入りの高ブリックス液を得る高ブリックス液浸漬工程と、(B)工程(A)で得られた吸水素材入りの高ブリックス液と、発酵前の発酵乳ミックスまたは発酵後の発酵乳を混合した後、得られた吸水素材入りの発酵乳ミックスまたは発酵乳を放置して、発酵乳ミックスまたは発酵乳に含まれている水分を吸水素材内に浸透させ、吸水した吸水素材入りの濃厚発酵乳ミックスまたは濃厚発酵乳を得る水分浸透工程、を含む吸水素材入りの濃厚発酵乳の製造方法。【選択図】なし
