  • A process that makes a small amount of ATP from Glucose
  • Does not use an electron transport train or oxegen to produce energy
  • Produces a charachteristic end product such as ethyl alcohol or lactic acid

Interesting Facts

Yeast should be kept in a cold and dry area and should be reduced daily to keep it healthy

Yeast transforms carbohydrates into alcohol and carbon dioxide. The alcohol is why the crust has an aroma and soft texture. The carbon dioxide is why there are air pockets that bubble.

Living Organisms and Fermentation in Pizza

The Living organism that performs fermentation in pizzia is yeast

Current research on this type of fermentation

In pizza you need to use yeast sparingly or it may continue to ferment after it leaves the oven

Fermentation and Pizza

Fermentation time should be proportionate to the protein content of the flour.

Hours: Lower protein content

Days: Higher protein content

Process of Fermenting Pizza

When was pizza discovered?

  • C6H12O6 ---> 2 CO2 + 2 alcohol molecules this is the chemical equation for yeast fermentation in pizza
  • The yeast under the right conditions convert sugar into energy
  • The biproduct of this reaction is CO2 and 2 alcohol molecues

Pizza was founded in 1889 by the greeks of Naples

The basic procedure for creating pizza dough

Evolution Of Yeast Fermentation

1. Put yeast in a bowl, and add sugar and warm water to it

2. Mix

3. Wait 5-10 minutes for it to release a few small bubbles

4. Take Bread Flower, salt, and milk and pour it into the batter, then add yeast

5. Knead dough for about 10 minutes, then slightly oil a bowl and put the dough in it

6. Poke dough with your finger about 3 times

7. Cover dough and allow it to rise for about 2 hours

8. Scoop out dough and knead it until it clings to what you are kneading it on

  • The first use of yeast in baking dates back to prehistoric times
  • Yeast is naturally found in grains such as whet or barley
  • The ancient Greeks begato make more advanced breads
  • Today machines speed up fermentation but they must be careful not to kill the yeast using to high temperatures
