Which statement best describes leavening in baking?

• A. It makes products rise by producing CO2 when combined with liquids.
• B. It adds sweetness to dough.
• C. It preserves flavor through salting.
• D. It improves browning in crusts.

Answer: (A)

Leavening in baking is the process that creates gas in the dough or batter, causing it to rise and become light and porous. The gas is mainly carbon dioxide produced by leavening agents when they react with moisture and heat (as in baking soda reacting with an acid, or baking powder releasing gas when wet and heated), or by yeast through fermentation. Those gas bubbles are what push apart the structure, and a gluten network or starch matrix traps the bubbles so the dough sets with volume. That’s why producing CO2 in the presence of liquids is the essence of leavening. Other elements like sweetness, preservation through salting, or browning in crusts involve different processes such as sugar addition, salt effects, or Maillard reactions, not the rise produced by gas.
