Productive Fermentation Experiment of Saccharomyces cerevisiae HD34-1

Abstract

Abstract: Saccharomyces cerevisiae HD34-1,a strain with the highest activity of alcohol dehydrogenase(ADH),was applied in the fermentation experiment of beer. During the productive fermentation,the physical and chemical indexes were determined. It was found that the alcohol content is below 1%(W/W),which accords with the request of alcohol-free beer. The fermentation conditions in 1-ton airtight fermentor were confirmed as follows:temperature 11℃,inoculum size 2%,terminating the fermentation when the sugar content declines to 5%,and reducing the temperature to 4℃ for storage.

Key words: alcohol-free beer, yeast, fermentation experiment
