BIOLOGICAL PROTECTION OF BARLEY GRAIN AND ITS INFLUENCE ON SELECTED FEATURES OF MALT.

The influence of 4 strains of Geotrichum candidum yeasts, used as starter cultures in the process of steeping of Rudzik and Maresi barley grain, on basic biotechnological qualities of malts was researched. The comparative sample was malt obtained from grain disinfected with the use of formalin. It has been observed that Rudzik grain was more susceptible to the influence of G. candidum starter cultures. In samples of this variety the starter cultures brought about higher extract yields of malts, higher protein modification and darker worts. From among the strains which were used, G. candidum 1 significantly influenced the qualities of malts rising their diastatic power and extract content, improving the dynamics of wort filtration and reducing its viscosity.
