If the jam was cooked in compliance with all recommendations, and the preservation itself was stored correctly, then it can be stored for 3 to 5 years.

However, the shelf life also depends on several factors:

  • if a large amount of sugar is added to the jam during cooking, the preserve will begin to become sugary over time - but it can still be safely eaten or used for baking;

  • an insufficient amount of sugar can lead to the fact that the jam spoils quickly - such a product can not stand for even six months.

How to understand that the jam is no longer suitable for consumption

The most important thing is to look at the quality of the preparation itself.

If you notice signs of fermentation or the appearance of mold, it is better not to eat it.

Also pay attention to the following points:

  • rust has appeared on the inside of the metal lid - it is better not to eat;

  • even if the lid swells a little - refuse consumption;

  • the preservation became unfit for food if mold appeared even on the lid, and not on the jam.

How to extend the shelf life of jam

To extend the shelf life of candied jam, you can boil it again with hot water and citric acid.

Roughly, the proportions should be as follows: for 1 liter of jam, you need to take 1/4 cup of boiling water and 2 g of citric acid.
