Does baking soda go bad?

No, baking powder does not go bad. Although, since it is a powder, it does not spoil on its own the way that other food items do, its effectiveness as a leavening agent does diminish with time. If moisture is allowed to enter the jar, wet clumps and mold will begin to develop, rendering the food unfit for consumption.

The fact that most baking soda containers include a best-by date does not imply that it is hazardous to use beyond that date.

While using expired baking soda may not make you sick if it has not been damaged with moisture and air pollutants, your cookies may not turn out as well. However, they may not look quite right.

Baking soda is used in certain baking recipes to help the baked goods rise and become fluffy and tender.

  • Make use of this easy test to see whether your baking soda is still somewhat suitable for baking purposes.
  • In a small mixing basin, combine 14 tsp baking soda.
  • Toss the powder with a tsp of vinegar or lemon juice and mix well.
  • If the liquid immediately begins to bubble vigorously, the baking soda is still suitable for baking. If you only receive a little amount of fizz, your baking soda is no longer usable for baking, but you’ll still use it for cleaning purposes.
