LEAVENING AGENTSMakes a baked product rise.

• What is the difference between baking soda and
  baking powder?
• Baking soda is pure sodium bicarbonate. When
  baking soda is combined with moisture and an
  acidic ingredient, the resulting chemical
  reaction produces bubbles of carbon dioxide that
  expand under oven temperatures, causing the baked
  good to rise.
• Baking powder contains sodium bicarbonate, but it
  includes the acidifying agent already (cream of
  tartar).

YEAST BREADS

• Yeast breads use YEAST as a leavening agent.
• Yeast needs warmth, food and moisture to grow.
• Small amounts of sugar speeds the activity of
  yeast. (too much sugar will inhibit yeast
  activity)
• Salt inhibits the speed of yeast activity.

YEAST BREADS

• Temperature and yeast
• 50 degrees- yeast begins to activate
• 78-82 degrees- yeast produces the most gas
• 120 degrees- yeast begins to die
• 143 degrees- yeast is useless for baking.

YEAST BREADS

• KNEADING DOUGH
• Kneading dough develops gluten to give the dough
  shape.
• Gluten- a protein in flour.
• If you stir wet flour mixture a little, gluten
  develops a little and bread is tender.
• If you stir (knead) wet flour mixture a lot,
  gluten develops a lot and the bread is tough.
• You only want to stir/mix quick breads a little
  to form a small amount of gluten
• You want to stir/mix (knead) yeast breads a lot
  to form a large amount of gluten.

YEAST BREAD BAKING BASICS DVD ANSWERS

• Why is it important for the water to be the

- Yeast is a living organism and if the water is
too hot it will kill the yeast and the dough will
not rise.

• What do fats do in yeast breads?

- Fats make breads soft and tender.

• Name 2 types of flour available for making bread?

• Rye, soy, whole wheat, rice, all-purpose, bread
  flour.

• What does kneading do for the bread?

• It forms gluten. It makes the dough smooth and
  elastic.

• How can you tell if you have kneaded bread long
  enough?

- When an indentation in the center of the bread
stays in place.

• What purpose does sugar serve to yeast bread?
