Fermentation uses yeast to convert glucose into ethanol and carbon dioxide.
C6H12O6 + Zymase (YEAST) → 2C2H5OH + 2CO2
Yeast contains the enzyme ZYMASE - this is the catalyst for the reaction. Fruits, vegetbales and grains all contain glucose, so they can all be used for fermentation.
- Temperature around 30°
- pH level between 6-7, as too much acid or alkali can stop the enzyme from reacting
- Anaerobic conditions (no oxygen can be present as it turns ethanol into ethanoic acid)
