Expiration & Storage Tips
When does powdered peanut butter expire?
When unopened, a jar of powdered peanut butter can last between one to two years in a cool, dry place. Just make sure to check the 'best by' date printed on the package. Once opened, it generally keeps its quality for about 3 to 6 months if stored properly. If it's homemade, its shelf life significantly decreases to just a few weeks. Freeze drying is not generally recommended for this type of product due to its already dehydrated nature.
How do you tell if powdered peanut butter is bad?
Powdered peanut butter doesn't spoil in a way that's harmful for consumption but its quality deteriorates over time. Telltale signs include any off-putting smell, discoloration, or a change in texture - it might form clumps if exposed to moisture. If any sign of mold is visible, it's a clear signal that it's spoiled and should be discarded. Always trust your nose and eyes - if it looks or smells off, its best to toss it out.
Tips for storing powdered peanut butter to extend shelf life
• Store in a cool, dry place away from direct sunlight.
• Once opened, ensure the lid is tightly sealed after each use to prevent air and moisture from entering.
• Use clean, dry utensils to scoop out the powdered peanut butter to avoid introducing any moisture.
• For longer shelf life, you can refrigerate it. However, it is not necessary and may cause the powder to harden.
• Transfer portions to a smaller airtight container if the original one becomes too large due to usage. This decreases the powder's exposure to air, helping to maintain quality.
