First, glutathione is extracted from an enzyme using acid or hot water, and the extract is adjusted to pH 2 to 4 and stored. On the other hand, the remaining bacterial components (mainly proteins) are extracted from the residual enzyme using a normal method, for example by using a cell wall lytic enzyme, and the extract is mixed with the glutathione extract and the pH is adjusted to 5. The inventors have now invented a method for obtaining a yeast extract with a high glutathione content without substantially reducing the glutathione contained in the yeast by spray drying the yeast.
