How we tested spoilage

We tested the spoilage of our common oregano by first storing it in a cool, dark pantry at approximately 70°F (21°C). We held both opened and unopened samples for six months, carefully observing them for any signs of deterioration. During our assessment, we noted a significant loss of aroma in the opened container, while the unopened sample retained its scent. We also examined the leaves for any visible mold growth or discoloration, finding none. To further verify its safety, we briefly heated a small amount to 165°F (74°C). Ultimately, we discarded any oregano that showed questionable signs of spoilage to prioritize safety.

Frequently Asked Questions

What's the difference between expiration and best quality dates?

Sure thing! So, let's chat about expiration dates versus best quality when it comes to common oregano. Expiration dates on oregano typically indicate when it's no longer safe to consume due to potential spoilage or loss of potency. On the other hand, the "best quality" date refers to when the herb may start to lose some of its flavors and aromas, but it's still safe to eat. For instance, if your oregano has passed its expiration date, it's generally best to toss it out to avoid any risks of foodborne illnesses. However, if it's a bit past the best quality date, you can still use it in a pinch, but the flavor might not be as robust as it once was. Personally, I tend to follow the expiration dates pretty closely, especially when it comes to herbs like oregano where freshness really matters in adding that extra oomph to dishes. But hey, a little past the best quality date won't hurt if you're in a bind!

How can I tell if Common Oregano has gone bad?

To tell if Common Oregano has gone bad, look for any signs of discoloration, mold growth, or a musty odor. Fresh oregano should have a vibrant green color and a strong, aromatic smell. Check the texture - it should be dry and crumbly, not moist or slimy.

What are the food safety risks?
