Expiration & Storage Tips
When does potato flour expire?
Unopened, potato flour can last for about 1 to 2 years past the date printed on the packaging, if stored in a cool, dark place. Once opened, it can last up to 8 months if it is stored in a tightly sealed container in a cool, dark place. Freezing potato flour extends its shelf life to about two years; however, due to its light and powdery texture, be sure to keep it in a sealed, airtight container to avoid moisture accumulation. For homemade potato flour, always use it within 8 months for optimum flavor and texture.
How do you tell if potato flour is bad?
Like other flours, potato flour has a fairly long shelf life, but there are a few signs to look for when determining if it's gone bad. A change in color to grey or a patchy appearance indicates mould or spoilage. You may also notice a sour or off smell, unlike the usual mild scent of potato flour. If you notice any changes in color, smell, or texture, it's best to discard the flour to avoid health risks.
Tips for storing potato flour to extend shelf life
• Always store potato flour in a cool, dry area away from direct sunlight.
• Transfer the flour to an airtight container once opened to keep it fresh.
• Consider vacuum sealing bags for long-term storage to keep out air and moisture.
• Don't store potato flour near odorous foods or substances. It can absorb those scents, affecting the taste and smell of your flour.
• If you choose to freeze potato flour, thaw it at room temperature before using. Make sure to stir it well to redistribute any moisture resulted from freezing.
