Question

While baking bread, Sunita mixed yeast and sugar in boiling water and added the
mixture in plain flour. She kneaded the mixture until soft dough was formed,
covered the dough with a cloth and left it in the corner of the kitchen to rise. After
an hour, she was disappointed to see that the dough had not risen at all. She had to
discard the dough and start the process all over again. What advice would you give
to Sunita to make the dough rise? Explain the purpose and function of yeast in
bread baking.

Answer 1

Explanation:

Yeast reproduces rapidly and produces carbon dioxide during respiration. Bubbles of the gas fill the dough and increase its volume. This is the basis of the use of yeast in the baking industry for making breads, pastries and cakes
