Baking Powder has a Short Shelf Life
- Baking powder does not have a long shelf life.
- Baking soda cannot be substituted for baking powder.
- Most commercially-produced baking powder contains aluminum.
Due to its short shelf life, baking powder is not good for storing with emergency food supplies. However, the main ingredients of home-made baking powder, baking soda and cream of tartar, will remain good almost indefinitely if they are stored separately.
Many people avoid baking powder with aluminum because they believe it gives food a vaguely metallic taste, and because it has been suggested that there may be a link between aluminum consumption and Alzheimer’s disease. Studies have not proven this, however. Home-made baking powder does not contain aluminum.
