Abstract RU 2418057 C1

FIELD: food industry.

SUBSTANCE: jeera and hop are mixed in mass ratio 1:10 and obtained mixture is extracted by means of liquid nitrogen with corresponding miscella separation. One cuts oyster plant, dries it in microwave oven till residual humidity about 20% at microwave field power providing warming of oyster plant inside the bits till temperature 80-90°C during at least an hour and fries oyster plant. Oyster plant and malt are mixed in mass ratio 1:(10-25). The produced mixture is impregnated with the separated miscella with simultaneous increase of pressure up to a value that corresponds to pressure of saturated nitrogen vapours at the temperature of impregnation. Pressure is reduced down to atmospheric value with simultaneous freezing of mix and its cryo-grinding in the medium of released nitrogen. Drinking water is poured over it. The mixture is saccharified to obtain wort. Beer yeast is added to wort; main fermentation, after fermentation and filtration are carried out.
