1 Leavening Agents in Baked Goods

2 Leavening baked goods is a process that causes the product to be light and porous.. Leavening involves producing a gas that expands the batter or dough leaving holes as the dough/batter sets during the baking process What is it?

3 The most widely used leavening agents are: Baking soda Baking soda Baking powder Yeast Baking powder Yeast

4 Steam and air also considered leavening agents: Steam is created when a very hot 400 degree oven is used. These high temperatures cause the liquid in the recipe to create steam. The egg and gluten in the batter forms around the steam to create the structure of the product as we see in popovers. Steam is created when a very hot 400 degree oven is used. These high temperatures cause the liquid in the recipe to create steam. The egg and gluten in the batter forms around the steam to create the structure of the product as we see in popovers. Air is used as a leavening agent when fat; sugar and sifted flour are mixed with an electric blender. During this process protein from the gluten is trap the air bubbles to create a light and fluffy product.

5 Quick Breads/Muffins Quick breads all contain flour, liquid and salt. Depending upon the recipe they may also contain fat, sugar and eggs. There are foud categories of quick breads depending upon the flour to liquid ratio in the product. The categories include: Quick breads all contain flour, liquid and salt. Depending upon the recipe they may also contain fat, sugar and eggs. There are foud categories of quick breads depending upon the flour to liquid ratio in the product. The categories include: Pour batters: popovers, pancakes, cream puffs._ 1:1 flour liquid ratio Pour batters: popovers, pancakes, cream puffs._ 1:1 flour liquid ratio Drop batters: muffins and some cookies. _ 2:1 flour to liquid ratio.

6 Yeast Yeast is a microscopic organism that works as a leavening agent. Yeast is considered a fungus related to the mushroom family. Yeast cells multiply and grow best when handled with care and allowed to grow where it is warm ( F ) and moist. And when it is combined with the proper food ( flour/sugar), liquid and warm temperature yeast produces carbon dioxide, expands and grows. This process causes the dough to expand and rise.

7 How do ingredients react to Yeast? SUGAR: is the food yeast needs to make the carbon dioxide gas which causes the dough to rise. It also helps the crust to brown and adds flavor SUGAR: is the food yeast needs to make the carbon dioxide gas which causes the dough to rise. It also helps the crust to brown and adds flavor FAT: helps to extend the shelf life of the dough. It also helps the dough to stretch easily when forming the crust. FAT: helps to extend the shelf life of the dough. It also helps the dough to stretch easily when forming the crust. FLOUR: when stirred and kneaded with the yeast mixture, the gluten stretches to form the elastic framework that holds the gas bubbles formed by the yeast. This makes the structure of the crust. The amount and quality of gluten caries depending upon the type of flour used.**Flours with the most gluten produce products with the biggest volume. The amount of flour needed for your dough varies slightly depending upon the weather conditions and type of flour used.

LIQUID: all liquids must be at the proper temperature to dissolve the yeast without killing it LIQUID: all liquids must be at the proper temperature to dissolve the yeast without killing it SALT: slows down the action of the yeast as well as draws out the flavor of the other ingredients. SALT: slows down the action of the yeast as well as draws out the flavor of the other ingredients.

8 USING WHOLE WHEAT FLOUR Whole wheat flour has less gluten than white flour. Whole wheat will produce a heavier and more flavorful pizza dough. Because of the increased fiber content it will not rise as high and will produce a denser chewier crust. Whole wheat flour has less gluten than white flour.

9 Kneading Use a flat surface that has a small amount of flour on it ( ¼ to ½). Also rub flour on your hands Form the dough into a round ball Form the dough into a round ball Fold it towards you. Fold it towards you. Using the heels of your hands, push dough away with a rolling motion. Using the heels of your hands, push dough away with a rolling motion. Turn dough one quarter turn around and repeat until dough is smooth and elastic (8 to 10 minutes) Turn dough one quarter turn around and repeat until dough is smooth and elastic (8 to 10 minutes) If dough becomes sticky, sprinkle board with flour under the dough and rub more flour on your hands. If dough becomes sticky, sprinkle board with flour under the dough and rub more flour on your hands.

10 Rising Rising time caries depending upon method used Rising time caries depending upon method used The dough should double in size The dough should double in size To check this press the tips of two fingers lightly and quickly ½ inch into dough. To check this press the tips of two fingers lightly and quickly ½ inch into dough. If the dent stays it has doubled. If the dent stays it has doubled.

11 Punching down the dough Using your fist punch dough down by gently pressing your fist down into the center Using your fist punch dough down by gently pressing your fist down into the center This action helps to eliminate the large air bubbles. This action helps to eliminate the large air bubbles. It also helps to build up the elasticity and makes the lighter more tender and easier to shape into your final creation. It also helps to build up the elasticity and makes the lighter more tender and easier to shape into your final creation.
