A preparation method of hemp protease hydrolyzate craft beer belongs to the technical field of fermented food. In order to further expand the application of hemp protein, the hemp seed meal was mixed with distilled water in a mass ratio of 1:10, the pH was adjusted to 5-6, papain and neutral protease were added for enzymatic hydrolysis, and the enzymatic hydrolyzed solution was centrifuged and taken up Clear liquid, collect hemp protease hydrolyzate <3kd, freeze-dry the enzymolyzate at low temperature in vacuo to obtain freeze-dried powder; mix malt and water in a mass ratio of 1:4, heat up to 60-65°C, keep warm for 90min, The temperature is then raised to 78-80°C, and the temperature is kept for 20-30min; filter to obtain wort, add freeze-dried powder and hops to boil, cool after filtration, add brewer's yeast to ferment, and then keep at 4-6°C for 10-15d. The invention not only improves the nutritional value of beer, but also improves the taste and flavor of beer, expands the application of hemp seed protein in the field of fermented food, and improves the added value of hemp seed deep processing. |
