People frequently overlook buttermilk amidst the variety of food choices when they’re doing their grocery shopping at the supermarket.
In fact, according to the U.S. Department of Agriculture (USDA), buttermilk is the third most popular milk alternative in America.
So, what makes this dairy product so special?
Well, buttermilk contains high levels of calcium and vitamin D.
This is great news for people who are looking to increase their intake of these nutrients.
However, like any other food, buttermilk also has an expiration date.
If left unopened, buttermilk will keep its freshness and taste for up to seven days.
After that, it starts to lose some of its nutritional value.
The longer you leave it on the grocery store shelves, the more likely it is to spoil.
And once it’s spoiled, it won’t necessarily have the same flavor as before.
Can buttermilk spoil?
There are two main reasons why buttermilk can become contaminated with bacteria:
- It is exposed to air or light
- The container leaks
For example, if you buy a carton of buttermilk at the grocery store and leave it open in your fridge, it will begin to deteriorate.
Bacteria will start growing inside the container, which will make it difficult for you to consume the whole thing.
To avoid this problem, you need to store your buttermilk in a closed container.
It is important to note, however, that even though it may look okay on the outside, buttermilk that smells sour or has a foul odor is definitely rotten.
How long does buttermilk last?
According to the USDA, buttermilk has a shelf life of five years.
That means that you should plan ahead and refrigerate your buttermilk immediately after opening it.
If you don’t, it might start deteriorating faster than expected.
However, buttermilk doesn’t have to stay in the refrigerator forever.
You can easily use it within 10 days.
Just remember that the sooner you eat it, the better quality it will be.
For instance, if you want to use it for cooking, then you should cook it right away.
What are the signs of bad buttermilk?
As mentioned earlier, buttermilk that has been exposed to air or light will start losing its nutritional value.
Here are some of the warning signs of bad buttermilk:
- A strong smell of ammonia
- Foamy texture
- Dark color
- Greenish tint
If you notice any of these signs, then it’s time to throw out your buttermilk and replace it with new.
How can you tell if buttermilk has gone bad?
One way to tell whether your buttermilk is still edible is by using a pH test kit.
These kits can detect changes in the acidity level of buttermilk over time.
To perform a test, just add a few drops of buttermilk into the test tube provided by the kit.
Once the mixture is mixed together, wait for about 15 minutes.
Then, take a reading with the pH meter.
If the reading falls between 5.0 and 6.5, then your buttermilk is still good to go.
However, if the reading falls below 4.8, then it’s time to toss it out because it’s no longer safe to consume.
How can you tell if buttermilk has gone bad?
Another way to tell whether your buttermilk is still safe to consume is by tasting it.
If it tastes sour, bitter, or otherwise unpleasant, then it’s probably too old to consume.
But if your buttermilk tastes fine, then you know that it’s still safe to eat.
Is it safe to drink spoiled buttermilk?
Yes, it is!
According to the FDA, there are no health risks associated with consuming spoiled buttermilk.
As long as it was stored in a sealed container, it will still contain all of the nutrients that it had before it went bad.
However, if you accidentally ingest some spoiled buttermilk, then you should consult a doctor.
They can help you figure out how much of the dairy product you ingested and advise you on how to treat it.
What happens if you drink spoiled buttermilk?
In rare cases, drinking spoiled buttermilk could result in diarrhea, nausea, vomiting, abdominal cramps, and bloating.
But since these symptoms usually occur only after you’ve already consumed some of the tainted dairy product, they are unlikely to happen to you.
Most people who experience these symptoms are sensitive to lactose, a sugar found in dairy products.
If you are lactose intolerant, then you should consider replacing some of the buttermilk in your diet with another dairy product such as yogurt or cottage cheese.
How do you store buttermilk to prevent it from spoiling?
You can store buttermilk in the fridge for up to 10 days.
Make sure that you always store it in a tightly sealed container.
Also, make sure that you never leave it out in direct sunlight.
What is the shelf life of buttermilk?
Buttermilk has a shelf life of five years.
That means that you should plan ahead and refrigerate your buttermilk immediately after opening it.
However, if you don’t, it might start deteriorating faster than expected.
How can you extend the shelf life of buttermilk?
When storing buttermilk, you should follow the recommendations listed above.
Also, you should try to keep the buttermilk in a dark place where it will not get exposed to light or air.
You can also extend the shelf life of buttermilk by adding lemon juice to the mixture.
Lemon juice helps preserve the buttermilk by killing off any harmful bacteria that may be present in it.
Is there a way to salvage spoiled buttermilk?
If you think that your buttermilk has gone bad, then you should try to salvage it.
You can do this by simply mixing it with some water and ice.
Then, strain the mixture through a sieve to remove the solid particles.
This process will help you recover the liquid part of the buttermilk while removing the solids.
You can then use the recovered buttermilk in your recipes.
