Liquids

  • Liquids gives baked products moistness and texture
  • It’s important in hydrating protein, starch, and leavening agents

Leavening Agents

  • Leavening agents is the ingredient in baking that makes the baked product rise
  • It is responsible for the production and incorporation of gases during the baking process

Leavening agent types

  • Yeast comes in two types; 1) active dry yeast or instant yeast-which has coarse oblong granules; 2) instant yeast or rapid-rise yeast has smaller granules and dissolves faster
  • It is used for breads due to its gluten-formation and stabilization characteristics in the fermentation process
  • Baking soda, also known as sodium bicarbonate. It is a fine white powder and has a slightly salty and alkaline taste
  • Baking soda is good for baking muffins, cakes, cookies, and pastries due to its fast action of chemical leavenirs
  • Baking powder is a mixture of baking soda plus an acid to react with it, and starch to prevent lumping
  • Baking powder is available in two types; 1) single-acting baking powder which requires only moisture to release gas, 2) double-acting baking powder releases gas in two stages: first, during mixing; second, it completes the reaction with the addition of heat during baking

  • Some of the functions of eggs in baking:
  • Protein in egg contributes to the structure of the baked product
  • It serves as an emulsifier and contributes to volume and texture
  • It is a leavening agent. When egg whites are beaten, air is trapped in the foam bubbles and expand during baking
  • It gives moisture to the baked product due to the quantity of water in eggs
  • Eggs give flavor, color, texture, and nutritional value

Salt and Other Flavorings

  • Salt enhances color and sweetness of other ingredients
