How will we assay the rate of alcoholic fermentation in lab?
The rate of fermentation can be measured by placing a small amount of yeast and sugar solution in a fermentation tube.
As CO2 is produced, the bubbles collect at the top of the tube.After fermentation, the sugars are converted to alcohol, and the hydrometer will sink more after fermentation.
To measure ABV, you make two measurements with the hydrometer, one before fermentation and one afterward.
What is the process of alcoholic fermentation?
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.
How to do fermentation in lab?
Lesson 1
1Put 5 g of glucose in the conical flask and add 50 cm3 of warm water.2) Add 1 g of yeast to the solution and loosely plug the top of the flask with cotton wool.
3) Wait while fermentation takes place.
4) Remove the cotton wool and pour the invisible gas into the boiling tube containing limewater.
