Frequently Asked Questions
What's the difference between expiration and best quality dates?
▼
The expiration date on Mac and Cheese Powder indicates the date until which the product is guaranteed to be at its best quality. Over time, the flavor and texture may degrade, but it does not necessarily mean the product is unsafe to consume. If stored correctly, Mac and Cheese Powder can still be used after the expiration date, but the taste may not be as optimal.
How can I tell if Mac and Cheese Powder has gone bad?
▼
If the Mac and Cheese Powder has gone bad, it may show signs of discoloration, clumping, or a strange odor. Check for any visible mold growth or off-putting smells that indicate spoilage. Additionally, if the powder feels unusually hard or moist instead of its usual powdery texture, it is best to discard it.
What are the food safety risks?
▼
Mac and Cheese Powder, being a dehydrated product, is generally considered safe if stored properly. However, care should be taken to prevent moisture contamination as it can lead to mold growth. To reduce the risk of foodborne illnesses, always store in a cool, dry place and avoid using the product if you notice any signs of spoilage.
What are some pro storage tips?

To maintain the quality of Mac and Cheese Powder, store it in an airtight container in a cool, dry place away from direct sunlight.
