Parameters influencing yeast growth and fermentation of barley malt

2 Parameters influencing yeast growth and fermentation of barley malt 

During brewing operations, there are numerous factors affecting the growth of yeast cells and snbseqnent fermentation of wort. Therefore, when attanpting to model and explain this phenomenon, it is imperative to know which parameters affect fermentation and in what manner. A typical fermentation will be affected in many ways, such as the rate of fermentation, the degree to which the media fermented and the ratio of products (and by-products) that are formed. These are affected not only by extrinsic parameters such as temperature and headspace composition, but also by numerous

Although the concentration of sugars will ultimately define the maximum aud miu-imum parameters of any equation that attempts to model this fermentation behaviour, the shape will be iuflueuced by the aforemeutioned intrinsic and extrinsic parameters. Novel research on how both extrinsic and intrinsic parameters affect fermentation is completed at many notable institutions, as discussed by other researchers mentioned in this text.
