Baking soda goes bad after 30 days because it starts to absorb moisture and odors from the environment, reducing its effectiveness. This degradation affects its ability to act as a leavening agent in baking and as a deodorizer. To prolong its lifespan, store it in an airtight container in a cool, dry place.
FAQs & Answers
- How long does baking soda last before it goes bad? Baking soda typically stays effective for about 30 days after opening if not stored properly, as it absorbs moisture and odors that reduce its potency.
- What is the best way to store baking soda to prevent it from going bad? To keep baking soda fresh longer, store it in an airtight container in a cool, dry place away from strong odors and humidity.
- Can expired baking soda still be used in baking? Expired baking soda may not work properly as a leavening agent because it loses its strength over time and after exposure to moisture and odors.
