Disclosed is a method for producing a yeast containing glutamic acid at a high concentration. Specifically disclosed is a method for culturing a yeast, in which an yeast that is in a stationary growth phase is cultured in a liquid culture medium having a pH value of not lower than 7.5 and lower than 11. By adjusting the pH value of the liquid culture medium for the yeast that is in a stationary growth phase to any value falling within the range of not lower than 7.5 and lower than 11 and subsequently further culturing the yeast in the liquid culture medium, it becomes possible to produce a yeast containing glutamic acid at a high concentration. In the method, Saccharomyces cerevisiae or Candida utilis can be used as the yeast. Therefore, by using the yeast containing glutamic acid at a high concentration produced by the method or an extract of the yeast, it becomes possible to provide a flavor additive composition, a food or a beverage containing glutamic acid at a high concentration. |
