Shelf life secrets: does buttermilk powder last forever?

Buttermilk powder, a versatile ingredient in baking and cooking, raises a common question among home cooks and bakers: does it expire? Understanding the shelf life of buttermilk powder is crucial to ensure its quality and effectiveness in your culinary creations.

Shelf Life of Buttermilk Powder

Unopened: Unopened buttermilk powder has a shelf life of approximately 2 years when stored in a cool, dry place. The airtight packaging helps preserve its freshness and prevent moisture from entering.

Opened: Once opened, the shelf life of buttermilk powder is reduced to about 6 months. Exposure to air and moisture can cause the powder to degrade over time.

While buttermilk powder typically has a long shelf life, it’s possible for it to spoil. Here are some signs to watch out for:

• Clumping or hardening
• Discoloration (yellowing or darkening)

If you notice any of these signs, it’s best to discard the buttermilk powder.

Benefits of Buttermilk Powder

Buttermilk powder offers several benefits in baking and cooking:
