Yeast extract is a cheap and convenient substitute or replacement for yeast nutrient in home brewing and yeast culturing. In order to do this the yeast extract is made from the cooked and dismembered cells of yeast produced as brewing waste. • For more information this is the link to a video on Yeast extract. • WTF is Vegemite • This video goes over some of the work and results found when investigating yeast extract being used to make beer in prisons. To spoil the the end of that investigation beer can not be made that way. • The video at the end shows the reaction difference between a yeast culture made from 5-10% sugar and the presence of 5g yeast extract , or not, in 1 L of water. 1/3 of the amount of sugar was used in the yeast extract culture than in the sugar and water yeast culture. • The fizzing directly relates to the amount of yeast growth. Suspicion is surface tension being released or enzyme reaction. This needs to be looked into more but it is a useful tool for demonstrating the difference in yeast growth. • The tables and graphs presented are from the linked article and it is worth reading for more information and context. • • Relevant links: • https://www.ncbi.nlm.nih.gov/pmc/arti... • https://www.ncbi.nlm.nih.gov/pubmed/1... • https://www.jstage.jst.go.jp/article/... • https://www.ncbi.nlm.nih.gov/pubmed/4...
