METHOD FOR MAKING LIGHT BEER Russian patent published in 2010 - IPC C12C12/00 C12C7/00 

FIELD: food industry.

SUBSTANCE: method consists in using hops for wort making. The hops are extracted using liquid nitrogen with correspondent miscella separation. Sunchokes are used as a non-malted raw material, which is cut and dried in a microwave field to a residual humidity of about 20% at a microwave power that ensures heating sunchoke pieces from inside to a temperature of 80-90°C for at least 1 hour. The sunchokes and the malt are charged together into a cryogenic grinder in a weight ratio of 1: (40-60) and mixed up. The obtained mixture is impregnated with the separated miscella while simultaneously increasing the pressure to a value that corresponds to the pressure of saturated nitrogen vapours at the temperature of impregnation and then relieving the pressure to the atmospheric one and simultaneously freezing the mixture. The mixture is subject to cryogenic grinding in the environment of released nitrogen, poured with potable water and saccharified.

EFFECT: invention enables to reduce the duration of the process and to increase the foam stability of the target product.
