- the prepared sample was dispensed into 3 30 to 35ml flacon tubes, respectively.
- glutathione was extracted from the diluted cell solution dispensed in the flacon tube for 25 minutes using hot water at a temperature of 70 °C. The extract was centrifuged and the supernatant was recovered to prepare a crude extract.
- Alcalase and Flavorzyme from Novozyme were added with enzyme concentrations of 1 ul/ml (0.001%), 5 ul/ml (0.005%), and 10 Each treated with ul/ml (0.01%) and enzymatic reaction was performed at a temperature of 50° C. for 120 minutes.
- Glutathione was secondarily extracted from the enzyme reaction product solution using hot water at 70° C. for 25 minutes.
- the secondary extract was centrifuged and the supernatant was recovered to prepare a secondary crude extract.
- the glutathione content contained in the extract sample obtained by mixing the first crude extract and the second crude extract was analyzed by DTNB color development method in substantially the same manner as in Example 2-2.
- the dry powder of the crude extract was prepared by freeze-drying the mixed sample, and the weight of the dry powder obtained after freeze-drying the crude extract 10ml speed vac was measured to obtain the dry weight (g/L), and the dry weight was recovered.
- the total dry weight (g) of the dried crude extract was calculated by multiplying the liquid amount. By substituting the obtained total dry matter weight (g) in Equation 1, the dry matter yield (w/w%) was obtained and expressed as w/w% in Table 4 below.
- the dry matter yield of the extract for each type and concentration of protease is shown in FIG. 6 .
- the secondary hot water extract is prepared after treatment with a proteolytic enzyme, there is an advantage that the dry product of the yeast extract can be obtained in high yield without reducing the glutathione content, and the proteolytic enzyme is Alcalase is more preferable.
- the amount of the treated enzyme increased, the dry matter yield of the yeast extract also increased.
