Abstract RU 2397219 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the food industry, particularly to brewing technology. The method involves mixing kumquat peel and hop, extraction of the obtained mixture with liquid nitrogen and separation of the corresponding miscella, cutting, drying in a microwave field with given process parametres and roasting girasol/sunflower, mixing the girasol/sunflower with malt, saturating the obtained mixture with the separated miscella while simultaneously increasing pressure, reducing pressure to atmospheric pressure level with simultaneous freezing of the mixture. The mixture then 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 primary fermentation, fortification, after fermentation and filtration are carried out.

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