Embodiment 1
[0045] Embodiment 1: High I+G yeast extract product 1 obtained according to the method of the present invention
[0046] Main equipment: self-dissolving tank, evaporator; separator, spray tower.
[0047] Produce according to the following process (based on 30 kilograms of brewer's yeast mud):
[0048] Fresh beer yeast puree is preferred, transported and stored in a refrigerated truck, the temperature is not higher than 15°C, and the storage process is preferably not higher than 5°C. Sieve through a 60-200 mesh sieve to remove foreign matter such as hops.
[0049] Adjust the treated yeast slime to 8-18%, add NaHCO accounting for 2.0% of the total dry weight of yeast slime 3 After 2 hours of treatment below 10°C, separate again. Then add 1.5% NaHCO 3 Then treat at below 10°C for 1.5 hours, separate and wash until the pH is 6.0.
[0050] Adjust the concentration of yeast slime after the above treatment to a solid content of 10%, add 7% alcohol as an autolysis accelerator, ra...
Embodiment 2
[0054] Example 2: Yeast extract product 2 obtained according to the method of the present invention
[0055] The main equipment and materials are the same as above.
[0056] Produce according to the following process (based on 30 kilograms of brewer's yeast mud):
[0057] Fresh beer yeast puree is preferred, transported and stored in a refrigerated truck, the temperature is not higher than 15°C, and the storage process is preferably not higher than 5°C. Sieve through a 60-200 mesh sieve to remove foreign matter such as hops.
[0058] Adjust the treated yeast slime to 8-18%, add NaHCO accounting for 1.5% of the total dry weight of yeast slime 3 After 2 hours of treatment below 10°C, separate again. Then add 1.0% NaHCO 3 Then treat at below 10°C for 1.0 hour, separate and wash until the pH is 6.0.
[0059] Adjust the concentration of yeast sludge after the above treatment to a solid content of 12%, add 9% alcohol as an autolysis accelerator, raise the temperature to 48°C, t...
Embodiment 3
[0063] Example 3: Yeast extract product 3 obtained according to the method of the present invention
[0064] The main equipment and materials are the same as above.
[0065] Produce according to the following process (based on 30 kilograms of brewer's yeast mud):
[0066] Fresh beer yeast puree is preferred, transported and stored in a refrigerated truck, the temperature is not higher than 15°C, and the storage process is preferably not higher than 5°C. Sieve through a 60-200 mesh sieve to remove foreign matter such as hops.
[0067] Adjust the treated yeast slime to 8-18%, add NaHCO accounting for 2.0% of the total dry weight of yeast slime 3 After 1 hour of treatment below 10°C, separate again. Then add 1.5% NaHCO 3 Then treat at below 10°C for 2.0 hours, separate and wash until the pH is 6.0.
[0068] Adjust the concentration of the yeast sludge after the above treatment to a solid content of 15%, add 9% alcohol as an autolysis accelerator, raise the temperature to 45°...
