Example Embodiment
[0045] Example 1: High I+G yeast extract product 1 obtained according to the method of the present invention
[0046] Main equipment: autolysis tank, evaporator; separator, spray tower.
[0047] Production is carried out according to the following process (based on 30 kg of beer yeast paste):
[0048] Preferably, fresh beer yeast paste is transported and stored in a refrigerated truck at a temperature not higher than 15°C, and the storage process is preferably not higher than 5°C. Pass through a 60-200 mesh screen to remove hops and other foreign matter.
[0049] Blend the processed yeast paste to 8-18%, and add 2.0% of the total dry weight of the yeast paste with NaHCO 3 After treating for 2 hours below 10°C, separate it again. Add 1.5% NaHCO 3 It is treated at 10°C or less for 1.5 hours, separated and washed to pH 6.0.
[0050] The concentration of the yeast paste after the above treatment is adjusted to a solid content of 10%, and 7% alcohol is added as an autolysis accelerator. Th...
