Abstract

The invention discloses a method for preparing ginger beer, which comprises the steps of pasting, saccharifying, wort filtration, boiling, sedimentation, cooling, fermentation, filtration and filling. In the saccharifying step, when the temperature rises to 44 DEG C, fresh ginger juice of which the amount is 0.4 to 0.6 volume percent of that of setting cold wort is added; the steps of saccharifying, wort filtration, boiling, sedimentation, cooling and fermentation are carried out continuously; after the fermentation is completed, fresh ginger juice of which the amount is 0.4 to 0.6 volume percent of the total amount of fermentation liquor is added; and the mixed solution is uniformly mixed and filtered and filled to obtain the ginger beer. In the method, part of ginger juice is added first in the saccharifying step to enable amylase in a saccharified boiler to decompose a small amount of starch in the ginger juice to prevent the starch from influencing the stability of colloid, but part of the ginger juice component can be lost by the steps of wort filtration, boiling, sedimentation, cooling, fermentation and the like; and therefore, another part of the ginger juice is added after the fermentation is completed to supplement the nutrient and aroma of the ginger juice lost by the previous steps.

Summary of the invention

Technical problem to be solved by this invention be overcome ginger beer colloid in the prior art unstable, form throw out easily and influence the defective of outward appearance, a kind of preparation method of ginger beer is provided.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:

The preparation method of ginger beer of the present invention; Comprise that raw materials for production with ordinary beer carry out gelatinization, saccharification, wort filtration, boil, deposition, cooling, fermentation, filtration and can, wherein, in saccharification step; The fresh ginger juice that adds the cold wheat juice amount of typing 0.4～0.6% (volume) when temperature is raised to 44 ℃; Proceed saccharification, wort filtration, boil, precipitate, cool off and ferment, after fermentation is accomplished, add the fresh ginger juice of fermented liquid total amount 0.4～0.6% (volume) again; Mix, after filtration and can, promptly get ginger beer.Being chosen in saccharification step, to add the part ginger juice be that these two kinds of enzymes can divide the amount of starch of taking off in the ginger juice because in saccharification step AMS and beta-amylase are arranged, and temperature be elevated to 78 ℃ after glycase just be destroyed basically.

The preparation method of above-mentioned ginger beer; In saccharification step, when being raised to 44 ℃, temperature adds the fresh ginger juice of the cold wheat juice amount of typing 0.5% (volume), and proceed saccharification, wort filtration, boil, precipitate, cool off and ferment; After fermentation is accomplished; Add the fresh ginger juice of fermented liquid total amount 0.5% (volume) again, mix, after filtration and can, promptly get ginger beer.

Used fresh ginger juice is to add the ratio preparation that water is prepared into 300 kilograms of ginger juice in 100 kilograms of gingers among the aforementioned preparation method.

Compared with prior art, the present invention divides two portions to add fresh ginger juice, overcomes the disposable unsettled defective of colloid that joins in the fermented liquid to be caused of ginger juice.Add the part ginger juice earlier in saccharification step; Glycase in the brew kettle can divide the amount of starch of taking off in the ginger juice, avoids it to influence colloidal stability, but through wort filtration, boil, operation such as deposition; Can lose part ginger juice component; So, after fermentation ends, add other a part of fresh ginger juice to replenish the ginger juice nutrient and the fragrance of each operation loss of front.Ginger beer with the inventive method preparation has outside local flavor, nutrition and the colloidal stability of ordinary beer, also has the peculiar flavour and the nourishing function of ginger juice.

Embodiment
