A few sample questions
1. What gas does yeast produce that makes bread rise?
Answer: Carbon dioxide
Yeast ferments sugars in dough, producing carbon dioxide gas and alcohol. The CO2 gets trapped in the gluten network, causing the dough to rise.
2. What protein in flour gives bread its chewy, elastic texture?
Answer: Gluten
Gluten is formed when the proteins glutenin and gliadin in wheat flour combine with water and are kneaded. It creates an elastic network that traps gas and gives bread its structure.
3. What is the chemical leavening agent in baking soda?
Answer: Sodium bicarbonate
Baking soda is sodium bicarbonate. When combined with an acid (like buttermilk or lemon juice), it releases carbon dioxide, which makes baked goods rise.
