Beneficial Activities of Yeast
  1. In Backing Industry – Yeast is used in making bread. Fermentation is done by adding yeast to the wet flour. Yeast converts starch into sugar and sugar into carbon dioxide and ethyl alcohol with the help of zymase enzymes. Carbon dioxide comes out in the form of small bulges. This flour is filled in the bread mold and kept in a hot furnace, due to which the bread becomes puffy and porous.
  2. In Medicines – Tablets are prepared by mixing yeast with vitamins. These pills are useful in stomach diseases.
  3. As Food- Because yeast contains a lot of proteins, vitamins and enzymes, its tablets are made and used.
