I recently heard someone claim that jello will last forever in their survival food stores. Others claimed that nothing lasts forever and an argument ensued. So, I did some extensive research to settle the disagreement on how long jello lasts and this is what I found out.
Properly stored unopened jello powder has a shelf life of up to 1 year in your pantry as per manufacturer guidelines. Anecdotally, however, powdered jello is known to have a virtually indefinite shelf-life. Once prepared, jello will last 7 to 10 days in the refrigerator.
So, it looks like both of them were right. Even so, I think I’d err on the side of caution for this one. Let’s dive a bit more deeply into the details.
How Long Can Jello Sit Out?
Jello can sit out for varying lengths of time, depending on how it is prepared. Jello comes in many different forms with unique shelf lives. Always make use you take a peek at the best-by or use-by dates to ensure safety consumption
- Powdered jello mix has the longest shelf life. It can sit in your pantry for 6 months up to a year unopened. Once you open a packet of Jello mix, make sure you use it within 3 months. Otherwise, consider freezing it.
- Homemade jello should not be left out at room temperature as the proteins in the gelatin could denature, and the sugars could start developing harmful bacteria. Hot temperatures may separate the gelatin from the water resulting in a loss in consistency. Refrigerate homemade jello for the best results.
- Ready-to-eat jello comes in two forms. Pre-packaged jello that is stored at room temperature at the grocery store typically has a best-by date of 4 to 6 months. It may still be safely eaten for up to a month after its best-by date. Refrigerated prepared jello typically has a shelf-life of 2 to 3 months and should not be left out at room temperature.
How Long Does Jello Stay Good in the Fridge?
As we already mentioned, many jello varieties don’t need refrigeration as long as they are sealed. However, refrigeration will prolong the shelf life of these products, even with their already substantial shelf lives.
- Prepared non-refrigerated jello can be stored in the fridge for up to 6 months Some sources cite that jello can exceed its best-buy date by 1 month with adequate refrigeration
- Homemade jello should always be refrigerated. With refrigeration, your homemade Jello dessert can last up to 7 to 10 days.
- Pre-made desserts that you might find at the deli or bakery of your local supermarket should also be refrigerated and will keep up to 1 week.
How Long Does Jello Last in the Freezer?
It is not recommended to freeze jello as you significantly damage its consistency. When jello freezes, ice crystals form from the water that subsequently disrupts the bonds of the polymer-like proteins. When it thaws, the water and gelatin will separate, and you’ll have something more like lumpy Kool-Aid.
This unfortunate transformation won’t be harmful to you to consume, but you probably won’t enjoy it too much. If you want to go ahead and give it a try, this frozen concoction will be safe to consume up to a year after you freeze it.
Does Jello Go Bad Once Made?
Jello has an extraordinarily long shelf-life. That doesn’t mean it will last forever. Left in the refrigerator after made, it will begin to separate. It’s best eaten within 1 to 3 for the best texture and consistency but can last up to 7 to 10 days before it starts to mold or harbor bacteria that could you harm.
How Long Does Jello Last Past Expiration Date?
We discussed above how jello is sold with a best-by or a sell-by date. Some people speculate that prepared jello that’s stored at room temperature can essentially last indefinitely. However, just to be on the safe side, jello that is not refrigerated is still suitable for consumption 1 week after its sell-by date. When chilled, it will still usually be good to eat for 1 month past its suggested date.
Jello powder mix can still be used several months after it’s expiration date so long as it has not been open or exposed to moisture. If stored in a cool, dry place, you can still use it for up to 1 year. Inspect the packet for mold or other contaminants before using it.
How Do You Know When Jello Goes Bad?
Unfortunately, jello won’t last forever. The good news is there are several tell-tale signs that your jello is now a no-go, and it’s time to toss it.
- Texture- The water will separate from the gelatin and other ingredients, causing a drastic change in the jello’s consistency. The jello will take on a dried-out rubbery texture. This doesn’t necessarily mean that it is unsafe to eat, but it does mean you won’t enjoy your treat nearly as much. It’s a good indicator that you have only a couple of days until the formation of harmful bacteria or mold.
- Taste- If your jello begins to take on a bitter or alcohol-like flavor, that means that the sugars have started to ferment, forming alcohols. A by-product if this is process is the production of methanol, which can make you very ill if consumed.
- Color- Even if you keep your jello in an airtight container after making it, after a week or two, it might start developing blue, green, or white mold patches. If your jello is beginning to look a little fuzzy or you see dark specks or streaks running through it, you know it’s time to chuck it.
What Happens If You Eat Bad Jello?
Jello that has been appropriately stored, can last for a long time. Eating jello that has gone bad, however, could potentially have some unpleasant effects. While most people in good health will digest a small amount of mold just fine, some may experience nausea, vomiting, or allergic reactions.
The USDA warns that eating moldy foods or bacteria-contaminated foods can cause food poisoning or infections that may require medical attention. While these effects might be rare, tt’s best to play it safe and not test your luck.
How to Properly Store Jello
- Powdered jello mix should be stored in a cool, dry environment such as a pantry or cabinet. Once it has been opened, place the open envelope in a resealable baggy or Tupperware. It can be stored at room temperature or refrigerated for best results.
- Prepared sealed jello can be stored at room temperature in a cool, dry place as well if it’s a particularly warm environment. You can refrigerate it. Refrigeration not only improves the aesthetics of jello, but it will also help extend its shelf-life.
- Homemade jello should be stored in an airtight container, like this one found on Amazon, or a resealable plastic bag. Keep refrigerated in a cold section of your refrigerator.
How Can I Increase the Shelf Life of Jello?
You can increase your jello’s shelf-life by immediately refrigerating it at or below 40 °F; as soon as it is made and not leaving it out for long while in use. Store your jello in an airtight container or a resealable baggy. Make a concerted effort not to cross-contaminate when dishing out a serving by using clean hands and utensils.
How Long Are Jello Shots Good For
In the fridge, jello shots will remain good for 3 to 5 days. The alcohol and high sugar content might actually make them edible for much longer, however, jello will tend to dry out slowly over time. This makes them less than appetizing if kept around too long.
The next time someone asks you how long jello will last, tell them it depends on how many people are around. The truth is, they usually go much faster due to people eating it so you don’t have to worry about it going bad. Even so, if you want to make it in advance you will want to only do it a couple of days before they will be devoured.
