Frequently Asked Questions
What's the difference between expiration and best quality dates for Dehydrated Mashed Potatoes?
Over time, dehydrated mashed potatoes may experience a decline in quality due to moisture absorption and flavor degradation. While they may still be safe to consume past the expiration date if stored correctly, the taste and texture may not be as desirable. Differentiating between safety and quality is crucial - expired products may not necessarily be harmful but could lack the intended taste and consistency.
How can I tell if Dehydrated Mashed Potatoes has gone bad?
If dehydrated mashed potatoes have gone bad, they may appear discolored or have dark spots, emit a musty or off smell, and have a stale or rancid taste. Check for any signs of mold growth or unusual odors, and discard if the texture feels clumpy or grainy instead of powdery.
