Abstract

Industrial-scale brews were performed with grist composed of rice (50% of total weight grain) and malted barley (50%) with the supplement of hydrolysate of brewer's yeast (HBY). A control brew containing 38% rice and 62% malted barley without HBY was also carried out. The objective was to investigate whether HBY positively influences the characteristic of high-ratio adjunct (HRA) wort and beer. The data illustrated that HRA-HBY wort revealed a significant decrease of color (P < 0.001) and bitterness (P < 0.05) of final HRA-HBY beer. After three months of storage at room temperature, HAR-HBY beers remained clear. The addition of HBY increased viability and flocculation ability of yeast cells. Our current study suggested that the addition of HBY as a nitrogen supplement enhanced HRA beer fermentation and improved the characteristics of beer.

RESUMEN

Cervezas de escala industrial fueron realizados con el grano molido que abarca del arroz (50% de peso grano total) y de la cebada malteada (50%) con el suplemento del hidrolizado de la levadura cervecera (HBY). Un control fabricación de cerveza contener 38% de arroz y 62% de la cebada malteada sin HBY también fue realizada. El objetivo era investigar si HBY influencian positivamente la característica del mosto y de la cerveza del alto-cociente-adjunto (HRA). Los datos ilustraron que el mosto HRA-HBY reveló una disminución significativa del color (P < 0.001) y de la amargura (P < 0.05) de la cerveza final HRA-HBY. Después de tres meses de almacenaje en la temperatura ambiente, las cervezas HAR-HBY seguían siendo claras. La adición de HBY aumentó la capacidad de la viabilidad y de la floculación de las células de la levadura. Nuestro estudio actual sugirió que la adición de HBY mientras que un suplemento del nitrógeno realzó la fermentación de la cerveza de HRA y mejoró las características de la cerveza.
