実施例6で製造した培養物を15MPaで均質化したもの25重量部に、30%のぶどう糖果糖液糖、25%の還元水あめ、0.3%のビタミンC、0.3%の大豆多糖類および0.03%のスクラロースを含む水溶液を100℃で10分間殺菌したものを75重量部加え、ヨーグルト香料((株)ヤクルトマテリアル製)を0.1%添加して乳酸菌飲料を製造した。この乳酸菌飲料を65mL容のポリスチレン製容器に充填し、得られた乳酸菌飲料の製造直後(製品化時)と、10℃で21日間保存した後の生菌数を実施例1と同様に測定し、風味を評価した。この結果を表7に示した。また、この乳酸菌飲料の10℃で21日間保存後の生残率を以下の式により求めた。
生残率(%)=10℃、21日間保存後の生菌数/製品化時の生菌数×100
