METHOD FOR ACTIVATION OF BREWER'S YEAST Russian patent published in 2004 - IPC

Abstract RU 2234529 C2

FIELD: brewery, food and microbiological industry.

SUBSTANCE: method for activation of brewer's yeast involves treatment of yeast cell suspension in common with medium for activation (whey, beer wort or mixture of whey and beer wort) taken in the ratio = 1:0.5, respectively, by acoustic effect of low-frequency oscillation (20 - 2 x 10⁴ Hz) in rotor-pulse apparatus for 2 min. The frequency rotation and intercylinder gap values are 2 000 rev/min [209.33 s^-1] and 0.2-0.3 mm, respectively. Parameters of treatment are taken so that amount of dead cells will not exceed 10%. Invention provides significant improvement of brewer's yeast quality.

EFFECT: improved activation method.
