Beschreibung
Zusammenfassung:	An object of the present invention is to provide a method for producing an amino acid-rich yeast which contains free amino acid in a high concentration. The present invention provides a method for producing an amino acid-rich yeast, which includes liquid-culturing a yeast in a stationary phase of proliferation under the condition that the pH of a liquid medium is equal to or higher than 7.5 and lower than 11; a method for producing an amino acid-rich yeast, which includes adjusting the pH of a liquid medium of the yeast in a stationary phase of proliferation to equal to or higher than 7.5 and lower than 11, and further culturing the yeast in the above pH range; a method for producing an amino acid-rich yeast, wherein the yeast is Saccharomyces cerevisiae or Candida utilis; an amino acid-rich yeast obtained by any one of the above methods for producing an amino acid-rich yeast; the amino acid-rich yeast extract wherein the amount of a free amino acid is from 7.5 to 18.0% by weight per dry yeast cell; and an amino acid-rich yeast extract extracted from the above amino acid-rich yeast.
