The shelf life of instant and flavored oatmeal is lower than that of dried oats, which can remain fresh for up to two years if stored properly (6 months to 2 years). 

Oats’ flavor and quality are susceptible to deterioration with time; however, environmental factors such as moisture, air, and light can speed up this process.

How to Store it?

Dry oatmeal that has not been opened should be kept in a cold, dry area. Once the oatmeal has been opened, it should be stored in a plastic or glass container with a tight-fitting lid.

Oatmeal should be consumed as soon as possible after opening and no later than a year afterward. Oatmeals are very sensitive when it comes to the environment, and therefore, you should use them sooner rather than later.

But, in case you’re not sure when exactly you’re going to use it – freezing your Quaker Oatmeal is definitely an option. Freezing dry oats in a freezer bag are going to keep your oatmeal fresh and good to go for up to a year.


Can You Prolong Their Expiration Date?

Once opened, it is best to use the oatmeal within a year. But for unopened oatmeal, as long as you keep it stored correctly in a cool, dry place with no humidity, it should be okay past the expiration date.


Should You Put it in the Fridge?

Refrigerating cooked oats in sealed containers or resealable plastic bags will extend their storage life. 

However, conditions inside a freezer will do no harm to your oatmeal, so you should keep it as an option.Cooked oats can also be stored in the refrigerator, but only for approximately six days.


What Makes Quaker Oatmeal Go Bad?

The oats’ flavor, color, texture, and aroma can all alter as a result of oxidation and moisture. You shouldn’t buy oats if they have any dark or light specks, and they should be a light brown or cream tint. 

Aside from the conditions outside of the quaker oatmeal – insects and molds are two common culprits in this situation, so you should beware of it as well.


Signs that Oatmeal Has Gone Bad

If the food exhibits any of the following indicators, you should either dispose of it: dark areas, weird odors, or clumping. 

Since oatmeal reacts quickly to the surrounding conditions, it’s easy to spot (or smell) if something is wrong. 

In addition, you should examine your oats for any mold indications and changes in how it smells, looks, or feels to ascertain whether they can still be consumed safely. And in case it’s not – composting ruined oatmeal is definitely a great alternative.
