Expiration & Storage Tips
When does chestnut flour expire?
Unopened chestnut flour can last up to two years in a cool, dry place, although it's best to use within the first year for optimal flavor and nutritional value. Once opened, it should be used within four to six months. However, if it's stored in the freezer, it can last up to year, yet some of its unique flavors might diminish due to prolonged freezing.
How do you tell if chestnut flour is bad?
Chestnut flour has a distinct sweet and nutty aroma. When it goes bad, it might develop an off smell, a change in color or texture, and could also harbor tiny pests. If you notice a rancid or stale smell, or if you see bugs or mold in your flour, discard it immediately. Remember, when in doubt, throw it out!
Tips for storing chestnut flour to extend shelf life
• Always store chestnut flour in an airtight container to keep out moisture and pests.
• Keep it in a cool, dark, and dry place. If your kitchen is prone to humidity or high temperatures, consider refrigerating it to prolong its lifespan.
• If stored in the freezer, make sure to defrost it at room temperature for a couple of hours before using.
• Avoid using wet utensils to scoop out the flour as it can introduce moisture, promoting bacterial growth.
