Embodiment 1
[0033] Such as figure 1 , the production method of yeast cell wall breaking and preparation of yeast extract of the present invention, comprises the following steps:
[0034] (1) Activation: add water to the activation tank, raise the temperature to 30°C, add dry yeast, stir evenly for activation, keep the temperature at 30°C for 1 hour, and obtain the yeast solution;
[0035] (2) Salt dissolution: add salt to the yeast solution, raise the temperature to 55°C, and continue stirring for 5.5 hours to open and break the cell wall of the yeast to dissolve the contents of the yeast cells;
[0036] (3) Enzymolysis: Yeast extract enzyme is added, and the yeast extract enzyme will cut the long-chain protein released from the cells into amino acids, embryos and other substances, stimulate the fresh fragrance of yeast, and obtain the enzymatic hydrolysis solution;
[0037] (4) Enzyme inactivation: inactivate the enzymatic hydrolyzate in step (3) at 90°C for 30 minutes;
[0038] (5) ce...
Embodiment 2
[0046] The production method of yeast cell wall breaking and preparation of yeast extract of the present invention comprises the following steps:
[0047] (1) Activation: add water to the activation tank, raise the temperature to 27°C, add dry yeast, stir evenly to activate, keep the temperature at 27°C, and the time is 1.5 hours to obtain the yeast solution;
[0048] (2) Salt dissolution: add salt to the yeast solution, raise the temperature to 50°C, and continue stirring for 6 hours to open and break the cell wall of the yeast to dissolve the contents of the yeast cells;
[0049] (3) Enzymolysis: Yeast extract enzyme is added, and the yeast extract enzyme will cut the long-chain protein released from the cells into amino acids, embryos and other substances, stimulate the fresh fragrance of yeast, and obtain the enzymatic hydrolysis solution;
[0050] (4) Enzyme inactivation: inactivate the enzymatic hydrolyzate in step (3) at 92°C for 40 minutes;

Embodiment 3
[0059] The production method of yeast cell wall breaking and preparation of yeast extract of the present invention comprises the following steps:
[0060] (1) Activation: add water to the activation tank, raise the temperature to 32°C, add dry yeast, stir evenly to activate, keep the temperature at 32°C, and the time is 1.2 hours to obtain the yeast solution;
[0061] (2) Salt dissolution: add salt to the yeast solution, raise the temperature to 60°C, and continue stirring for 5 hours to open and break the cell wall of the yeast to dissolve the contents of the yeast cells;
[0062] (3) Enzymolysis: Yeast extract enzyme is added, and the yeast extract enzyme will cut the long-chain protein released from the cells into amino acids, embryos and other substances, stimulate the fresh fragrance of yeast, and obtain the enzymatic hydrolysis solution;
[0063] (4) Enzyme inactivation: inactivate the enzymatic solution in step (3) at 95°C for 25 minutes;
[0064] (5) centrifugation: t...
