Why do you add lemon juice to jam?
When you prep a big batch of jam, you begin by cutting the fruit and heating it with some sugar. The lemon juice lowers the pH of the jam mixture, which also neutralizes those negative charges on the strands of pectin, so they can now assemble into a network that will “set” your jam.
How soon can you eat homemade jam?
Q: How long can I keep my homemade jams and jellies once I open them? A: Opened home-canned jams and jellies should be kept in the refrigerator at 40°F or lower. “Regular” – or pectin-added, full-sugar – cooked jams and jellies are best stored for 1 month in the refrigerator after opening.
What happens if you eat expired jam?
Some are wondering if it’s OK to still eat jam or jelly, whether high-end or homemade, as long as you scrape off any visible mold.

Can 10 year olds eat jam?
Let’s start with an unopened jar of jam. Of course, homemade jams usually don’t retain taste as well as store-bought ones, but that doesn’t mean that after 1.5 or 2 years the jam will taste bland. So as long as the seal remains intact, it should be perfectly safe (and tasty!) for at least a few years more.
Should you keep jam in the fridge?
Jams and Jellies Jellies and jams do not need to go in the fridge because they have a water activity of around 0.80, and their pH is usually around 3. So they don’t have enough moisture to support bacteria and are too acidic for them as well. Conclusion: Keep your jams and jellies wherever you want to.
Does unopened jam expire?
Store-bought jam keeps quality for at least a year. Once you open it, it stays best for a couple of months. Homemade jam lasts about a year unopened, and for a month or two after opening.
How do you preserve jam without a canner?
Glass jars, the type you use for canning or even cleaned jars that previously held store-bought jam, are great. McClellan also likes lidded Pyrex containers. You can even use plastic so long as you let the jam cool first before pouring it in to avoid melting anything.
Can you get botulism from raspberry jam?
Almost all fruits are naturally below that pH level. So you can ‘t get botulism by canning at home, in a boiling water bath, a jar of Apricot– Raspberry –Mint Jam, applesauce, or plum preserves.

How long is sealed jam good for?
The act of canning doesn’t preserve food forever. But you can often get 18 months to two years out of your higher sugar products like jams and fruit canned in syrup. As long as the seal is good and the lid seems properly concave, your product should be just fine.
How long does homemade jam last once opened?
Once opened, keep your homemade jam in the refrigerator for up to three months. Homemade jams made without sugar and processed by canning in a hot water bath will last about half that long – about one year – when stored in cool, dry place out of direct sunlight.
