PROBLEM TO BE SOLVED: To solve the problem that a drink having a transparent state such as water is required, even in the case of an acidic lactic drink using a sterilized milk product drink as a raw material.SOLUTION: There is provided a transparent acidic lactic drink and a production method thereof. The production method comprises a pH adjusting treatment for blending a sterilized lactic acid bacterium drink or fermented milk with water, and preparing an intermediate drink having pH of 2.5-3.3 by adding a pH adjuster thereto, and a heat treatment for heating the intermediate drink at 80°C-85°C. In the transparent acidic lactic drink, a stabilizer comprising a thickened polysaccharide or a soybean polysaccharide is not blended, and an OD660nm value is 0.02 or smaller.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 殺菌乳製品飲料を原料とした酸性乳性飲料においても、水のように透明な状態を有する飲料が求められている。【解決手段】 殺菌乳酸菌飲料又は発酵乳、及び水を配合すると共に、pH調整剤を添加してpH2.5~pH3.3となる中間飲料を調製するpH調製処理と、前記中間飲料を、80℃~85℃で加熱を行う加熱処理とからなり、増粘多糖類若しくは大豆多糖類からなる安定剤が配合されず、OD660nm値が0.02以下である透明な酸性乳性飲料及びその製造方法。【選択図】 図1
