In this post, let’s dive deep into some facts and features of canned pumpkin so that you can make use of this tasty food more wisely!
How Long Can Canned Pumpkin Last In The Fridge?
When refrigerated, canned pumpkin will last about a week, but the freezing method can be last up to a half year.
Scroll down to discover more details about each method of storage.
The most common food storing method is refrigerating. And the typical temperature heat range used in a household refrigerator is from 1 to 3 Celsius degrees (35 to 40 Fahrenheit degrees).
Given that fact, the refrigerated food is usually stored within these heat ranges. However, have you ever wondered how long canned pumpkin could last within that standard heat range? And, if you change the range, can it remain usable for a longer time?
First, let’s discuss the typical shelf life of canning pumpkin butter. If stored in a refrigerator with the heat range mentioned above, the food can last for two years if remaining sealed.
If the can is unopened, then the temperature and the environment do not seriously affect the content; it can remain edible for the pumpkin purée recipe as long as the preservative works.
However, if the can is opened, then the case is entirely different. You have to put the pumpkin can in the refrigerator; otherwise, it will turn spoiled immediately a few hours after opening.
If opened canned pumpkin stays in a refrigerator within the 35 – 40 Fahrenheit degree, it is edible for a week.
Besides, if you want to lengthen the shelf life to 1 or 2 days more, please put the can in a cool, dark, dry place with little sunlight and moisture because moisture and heat are the canned food’s enemies shelf life.
You may wonder how long the canned freezing pumpkin can stay, right? We have to confirm that the frozen pumpkin purée’s shelf life is significantly longer than refrigerated.
We will only mention the opened pumpkin can in this part because how can you freeze a sealed canned food, right?
In terms of time, this frozen food can last for about 3 to 5 months after freezing. Normally, an opened can of pumpkin sits out for only a week, or even shorter if stored in a hot environment, but the freezing pumpkin can extend its longevity up to half a year. Quite impressive, right?
It takes you simple steps to freeze puree pumpkin at home with basic equipment. First, prepare an ice cube tray, fresh pumpkin puree (about 5 to 6 cups of pumpkin is enough).
Then, pour the pureed pumpkin into the ice cube tray until all slots are filled. Put the ice cube tray into the freezing shelf of the fridge. Wait for 2 or 3 hours for the pureed pumpkin to freeze.
Then, please take out the tray, use spoons to pluck the puree pumpkin cubes, store them in a plastic container in dark, dry places, in freezer bags, or else, freezer-safe container.
You can also keep it in an ice tray on the frozen shelf and take it out whenever you want a cup of pumpkin for some pumpkin puree recipes.
In short, freezing has always been a top-recommended method for storing for a long period. Freezing meat, dairy products, fish, vegetables, greens, or even canned food, always stretch the food’s shelf life twice or three times as normal.
Opened Can Vs. Closed Can
There is a huge difference between opened vs. unopened cans. The opened pumpkin butter can last for only a week or six months, depending on the temperature.
Meanwhile, the unopened pumpkin can still be available two years later after its release to the market.
Why is there such a huge gap between these two types? Well, it must be because of air exposure. When opening a can, the pumpkin butter is automatically exposed to the environment, containing many harmful bacteria and viruses.
There are dirt, germs, and microorganisms in the air either, most of which can also trigger the pumpkin’s spoiling process.
To be specific, these microorganisms can absorb into the pumpkin jam, trigger the germination process to destroy the texture, the taste, and later spoil the pumpkin.
On the contrary, the sealed canned pumpkin can last for two years (or even more) without any problem. These products have gone through a strict quality assurance process, ensuring that they can retain the taste as long as it is sealed.
The manufacturer has to confirm that the food is still edible whenever it is sealed; otherwise, they will lose your reputation so that you can trust that sealed canned pumpkin is available after a long time.
The date “1 or 2 years” is just a “best by date” presumption because the preservatives aren’t effective after two years. But, if the expiry date is longer than two years, then you can use it longer than the two years limit.
In case you use homemade pumpkin, then the case may be different. The homemade pumpkin puree may last for about 3 to 4 months if frozen and stored in the fridge.
The homemade pumpkin puree is also considered “opened” so the level of air exposure is higher.
However, compared to the manufactured puree, the homemade pumpkin puree is more delicious. There are a variety of homemade pumpkin puree recipes that you can choose and try for yourself.
How To Tell If Canned Pumpkin Is Bad?
Suppose you follow all storing guidelines, but you still aren’t sure if the pumpkin has turned bad. So, how can you figure out whether the canned pumpkin is bad or not?
The first indication is its fragrance. The normal canned pumpkin has a super signature cheesy, clingy, and vegetal odor. So, when you open the pumpkin can, take a deep sniff to test if there is any weird smell. If it is, you may need to throw away the can.
The second signal is the molds. When pumpkin butter turns bad, some molds will emerge on the juice’s surface extracted from the butter. Besides, there may be more juice than normal.
If seeing these indications, please carefully check the canned pumpkin before using it.
How To Store Canned Pumpkin For A Longer Period?
As mentioned above, the best way to keep canned food is always freezing. Hence, if available, we recommend you freeze the food for longer shelf life. This technique is convenient for both fresh and canned pumpkin to add-in.
Another suggestion is to keep the pumpkin in cool, dark, dry environments to prevent it from air and bacteria exposure as much as possible. If available, please put the opened pumpkin can in an airtight container in the fridge.
However, the most important factor for maintaining pumpkin is opened or unopened. When you have opened the pumpkin can, the longest shelf life is half a year, so please consider this point.
