METHOD OF BREWING FLAVOURED LIGHT BEER Russian patent published in 2010 - IPC C12C12/00 

FIELD: chemistry.

SUBSTANCE: invention relates to brewing technology. The method involves mixing orange peel and hop, extraction of the obtained mixture with liquid nitrogen and separation of the corresponding miscella, cutting and drying girasol/sunflower in a microwave field at given process parametres. The girasol/sunflower is then mixed with malt. The obtained mixture is saturated with the separated miscella while simultaneously increasing pressure to a value which corresponds to pressure of saturated nitrogen vapour at saturation temperature. Pressure is lowered to atmospheric pressure level and the mixture is simultaneously frozen. The mixture undergoes cryogenic grinding in the medium of the released nitrogen. Water is added and saccharification is carried out to obtain wort. Brewing yeast is added and fermentation and filtration are carried out to obtain the end product.

EFFECT: method shortens duration of the process and increases foam stability of the end product.
