[0025] Example 1
[0026] The specific operation steps of the present invention are as follows:
[0027] Take the waste dry yeast from the brewery and screen it through 80 mesh to remove impurities;
[0028] Add 10g of germanium dioxide (GeO2) in 50ml of distilled water, after fully dissolving, use
[0029] Potassium hydroxide adjusts the pH of the germanium solution to 5.8;
[0030] (3) Add the germanium solution to the dry yeast sieved in step (1) according to the ratio of 50ml germanium solution: 1000g dry yeast;
[0031] (4) The dry yeast added with germanium solution in step (3) is expanded with an extruder. The extruder can be SPJ-40, manufactured by Shaanxi Deai Food Co., Ltd. or South China Agriculture Developed by the university's food processing laboratory. The expansion conditions are:
[0032] Puffing temperature: 130℃
[0033] Feeding speed: 250g / min
[0034] Screw speed: 20Hz
[0035] Water supplement: 5g / 100g dry yeast
[0036] (5) Wash the expanded yeast with purified water ...
