ABSTRACT
The aim of the study was to evaluate the effects of ultrasound pretreatment, pullulanase digestion and hop α-acids preparation activity on the efficiency of simultaneous saccharification and fermentation of high gravity mashes prepared from rye starch. As a result of the ultrasonic pretreatment alone, or such treatment combined with pullulanase digestion, a decrease in viscosity of 60-69 and 85%, respectively, was observed. Also, the higher concentrations of reducing sugars were determined in these mashes (p<0.05). The pretreatment of rye starch with ultrasound for 10 min resulted in a higher (by over 21%) fermentation efficiency as compared to the control mash (p < 0.05). Pullulanase digestion preceded by the use of ultrasound pretreatment and the antimicrobial action of hop α-acid preparation resulted in a further increase in fermentation efficiency (by ca. 30%), in comparison to the control sample (p < 0.05).
