To provide a high fining technique for acidic milk-containing high-fineness beverage.A method for producing an acidic milk-containing high-clarified beverage comprises the steps of: preparing acidic milk which contains milk protein and has a pH of less than 3.5 heating the acidic milk at a temperature of 70 C. or more and less than 95 C. A step of heating and sterilizing the acidic milk, and a step of lowering the liquid temperature so that the liquid temperature of the acidic milk is 60 C. or less, and the temperature is lowered within 5 minutes after the step of heating and sterilizing In the step of starting the process and cooling the same, the acidic milk is cooled so that the liquid temperature is in the temperature range of 65 C. or more and less than 95 C. for less than 2 minutes, and the acid milk content high The absorbance of the clarified beverage at a wavelength of 660 nm is 0.02 or less.Selection drawing None【課題】酸性乳含有高清澄飲料の高清澄化技術を提供する。【解決手段】酸性乳含有高清澄飲料の製造方法は、乳タンパク質を含み、かつpHが3.5未満である酸性乳を準備する工程と、70℃以上95℃未満の温度で前記酸性乳を加熱殺菌する工程と、前記酸性乳の液温が60℃以下となるように前記液温を降温させる工程と、をこの順で含み、前記加熱殺菌する工程の後、5分以内に前記降温させる工程を開始し、前記降温させる工程において、前記液温が65℃以上95℃未満の温度領域にある時間が2分未満となるように前記酸性乳を冷却するものであって、酸性乳含有高清澄飲料の波長660nmにおける吸光度が0.02以下である。【選択図】なし
