10 Common Items Whose Expiry Dates You Probably Didn't Know About

We often rely on the expiry dates mentioned on packaged food products, but did you know that even unsealed or open items have a limited shelf life? Many everyday foods have expiry dates that are not commonly known. Let's take a look at 10 things that often get overlooked when it comes to their shelf life:

1. Flour

Flour is a pantry staple, but it doesn't last forever. While it may seem like it can be stored indefinitely, whole wheat flour tends to spoil faster due to its essential oils. Most flours can be kept for 6 to 8 months, but always check for any odd smells or tastes. If the flour feels off, it’s time to toss it.

2. Maple Syrup

Maple syrup is beloved for its sweetness, but once opened, it doesn’t last as long as you'd think. After opening, maple syrup can spoil in about 2 years. To extend its shelf life, make sure to store it in a tightly sealed jar in the refrigerator. If you see any mold, discard it immediately.

3. Frozen Food

Frozen vegetables, fruits, ready-to-eat meals, and meats are convenient, but their quality deteriorates over time. While they can last in the freezer for months, fresh-tasting veggies like peas, corn, and carrots should be consumed within a few weeks of purchase for the best flavor. Always check the expiry dates on frozen food bags.

4. Canola Oil

Canola oil can be stored for up to a year if kept in a cool, dry place. However, exposing it to heat can cause it to spoil prematurely, losing its aroma and flavor. Avoid storing it near the stove or in direct sunlight.

5. Baking Powder

Baking powder is a key ingredient in many recipes, but it loses its leavening power after about a year. To test its potency, mix a teaspoon of baking powder with half a cup of warm water. If it bubbles, it's still good. If not, it’s time to replace it.

6. Dried Spices

Spices lose their flavor over time, with the shelf life varying depending on whether they are ground or whole. Whole seeds and peppercorns can last for 3 to 4 years, while ground spices typically last 2 years. Green spices like celery and ajwain are best used within 1 year.

7. Ketchup

Though ketchup may seem like it lasts forever, it begins to lose quality about 4 to 6 months after opening. To preserve its flavor and texture, keep it refrigerated and consume it before the expiry date on the bottle.

8. Peanut Butter

Natural peanut butter is a popular spread, but once opened, its taste can begin to degrade after 3 months. Storing it in the fridge can extend its freshness up to 6 months.

9. Pickles

While pickles are packed in preservatives, they don't last indefinitely. After about a year, their flavor can change, and they may begin to spoil if not stored properly. If there's a thick or white layer on top, it's a sign that the pickles have gone bad.

10. Rice

Rice can last 1 to 2 years if stored properly in an airtight container. However, brown rice has a shorter shelf life of about 6 months. Keep rice in a cool, dry place, and avoid airtight containers, as they can trap moisture and lead to spoilage.
