Disclosed are: a process for producing a fermented milk which can produce a specific peptide having useful functions (e.g., anti-hypertensive effect) in a fermented milk with good efficiency and can impart excellent flavor and functional activities (e.g., anti-hypertensive activity) to a fermented milk beverage/food in a simple manner; and a fermented milk beverage/food having excellent flavor and functional activities which is produced by using the fermented milk. The process comprises the combination of step (A) with step (B): step (A) in which an animal milk casein is enzymatically digeste with a protease (1) including a specific protease (e.g., papain); and step (B) in which an animal milk casein or the like is fermented with lactic acid bacterium to thereby produce VPP, IPP and YP. The fermented milk beverage/food comprises the fermented milk produced by the process or a condensation product thereof and contains VPP, IPP and YP in given amounts or more in terms of the amounts determined upon drinking. |
