Sodium bicarbonate is a common leavening agent, also known as baking soda. It reacts with acidic components to release carbon dioxide in the baking process to give volume and tender textures. It can also be used in dry-mix beverages to give some carbonation qualities. This sodium bicarbonate is dispersed in hydrogenated vegetable oil. Hydrogenation is a process that alters the melting point of oils, making them solid at higher temperatures. Because it is hydrogenated, it contains saturated fats.
