A Neural Network Tool for Brewery Fermentations
Fermentation is an important, if not the most important process step in the production of beer. It is subject to alterations stemming from the variation in the yeast, a living organism, and due to the complex raw materials of biological origin. The variability may manifest in changes in the fermentation speed or cause off-flavors in beer. Thus, there is a need for tools, both analytical and com...
متن کاملMonitoring ester formation in grape juice fermentations using solid phase microextraction coupled with gas chromatography-mass spectrometry.
Volatile esters contribute important floral and fruity sensory properties to wine. Numerous factors influence the biosynthesis and hydrolysis of esters throughout yeast fermentation; however, methods to monitor the dynamic changes in ester production that occur during winemaking processes are limited. In this study, we showed that solid phase microextraction (SPME), a rapid, solventless samplin...
متن کاملPowering the porter brewery.
Before canals and railways developed as a major transport network, it was seldom profitable to transport beer inland over more than a few miles. In country towns and villages, therefore, beer would be brewed either by a small 'common' brewery that supplied a handful of pubs and private customers, or in an even smaller brew-house attached to the pub itself. Many families also brewed their own be...
متن کاملEster formation at the liquid–solid interface
A chemical reaction (esterification) within a molecular monolayer at the liquid-solid interface without any catalyst was studied using ambient scanning tunneling microscopy. The monolayer consisted of a regular array of two species, an organic acid (trimesic acid) and an alcohol (undecan-1-ol or decan-1-ol), coadsorbed out of a solution of the acid within the alcohol at the interface of highly ...
