In other words, brown rice can become spoiled more rapidly than white rice, with the following specific lifespan below:
White Rice – up to 2 years
Brown Rice – 3-6 months after the date of manufacture
Take note that there are labels for grains, and, as a consumer, you can refer to them. However, for best quality, you can refer to the information stated above.
How to Tell if the Dry Rice Has Soured
Every FDA-approved food has its expiry date and this goes the same for dry grains.
But, how can you tell if the cereal grains have deteriorated without looking at the expiration date?
For this, you might want to take a look at some of the spoilage signs below:
Rancid or off smell
Appearance of bugs
Any of these might lead to mold growth. Thus, to promote and extend the quality of your grains, it is advised to follow healthy storage conditions such as storing it in a cool, dry place, or an airtight container.
Shelf Life of Cooked and Freeze Cooked Rice
Now, let us talk about the lifespan of your cooked brown and white rice.
You might be worried about how long your leftover cereal grains will last after a huge party, and, still, the answer would be it depends.
After cooking rice, the food has an indefinite shelf life.
Generally, cooked brown rice and cooked white rice last for 3-4 days or up to one week when properly stored in the ref.
Moreover, frozen rice or freeze rice can last for 6-8 months as long as the temperature in the freezer constantly stays at 0°F.
Factors that Affects the Lifespan of Cooked Rice
So, if newly prepared brown or white rice can last up to one week in the refrigerator and 6-8 months in the freezer, what are the factors that can reduce this period?
1) Unrefrigerated for too long
You will only have 2 hours to refrigerate your hot white or wild rice because if you let cooked rice sit at room temperature longer than that period, the tendency is that the texture and taste will start to change.
Apart from this, bacteria may also start to grow after 2 hours at room temperature (68 °F).
Moreover, take note that even when you re-cook your cereal grains, the spores of Bacillus cereus may still survive which can cause you food poisoning.
Because of this, it is safe to say that refrigerating your cooked white rice or brown rice within a matter of less than two hours will help you keep your cereal grains optimal, healthy, and perfectly safe to eat.
2) Reheated cold rice more than a couple of times
Another factor that affects your newly prepared cereal grains’ sustainability is if it is cooled and reheated multiple times.
Remember, you cannot refrigerate rice back after reheating it even if you put it in the freezer!
What you can only do is get enough which you can consume or finish and heat that specific amount.
The golden rule? Never reheat refrigerated rice more than once.
3) Condition of the refrigerator
The condition of your refrigerator may also be a culprit why your cooked rice gets spoiled even after a day of refrigerating it.
If your ref is dry, you will also get dry and hard cereal grains. Unfortunately, dry rice also means spoiled or expired rice.
If your ref is too moist, your cereal grains may become susceptible to bacteria and you will know this if there are already some changes in the smell (unpleasant smell or strange smell).
Signs that the Cooked Rice Has Gone Off
Aside from noticing that the rice smells funny, there are other signs that your cooked or hot rice has gone bad. Some of these changes include the following:
Taste changes (sour)
The texture is moist and slimy
Mold starts to appear (green, blue, or black spots)
The cereal grains become hard and super dry (a clear sign)
If any of these signs are observed, it is highly advised to discard your food to avoid dangerous health outcomes.
How to Properly Store Leftover Rice in the Refrigerator
As said, even though you store your grains in the refrigerator, they can still be spoiled. So, what are the proper ways to store cooked rice in the ref?
Take a look at some tips below:
Store your cooked rice in an airtight container or resealable plastic bag
Keep your fridge clean
Again, if you want to store your cooked rice in the fridge for a longer period, you can freeze it (put it in the freezer) and store it in a heavy-duty freezer bag.
Dangers of Eating Spoiled Rice
Even if cooked rice lasts for a few days up to 7 days in the fridge, what would happen if you accidentally, or not, eat spoiled cereal grains?
Take note that when your cooked cereal grain is spoiled, molds and bacteria have already taken over.
According to a study in Korea, these molds and bacteria in your cereal grains will produce mycotoxins which are responsible for food poisoning.
So, if you do not want any of these health dangers to happen to you, follow the safety protocols regarding storing and consuming your cooked rice!
