Question

Write down the steps involved in an activity to show the process of fermentation by using maida dough.

Answer 1

• Fermentation is the chemical breakdown of a substance by bacteria, yeast or other microorganisms.
• Maida is used in making bread and other bakery products.
• The main ingredient used in making bread is Baker's yeast.
• Yeast is added for preparing the dough.
• Yeast gets activated in the presence of sugar and thus helps in fermentation.
• It contains the following enzymes:-

1) Amylase - changes a small amount of starch into maltose.

2) Maltase - changes maltose to glucose.

3) Zymase - Zymase complex acts on glucose to form ethyl alcohol and carbon dioxide.

• Production of carbon dioxide causes the dough to rise, this is called leavening or rising.
• The left dough is baked.
• The bread obtained is soft and fluffy.
• The sponginess is due to expulsion of carbon dioxide and alcohol.
