How long the homemade strawberry jam can be preserved depends on the sanitary conditions and preservation environment when making strawberry jam, which has a great relationship with the shelf life of strawberry jam. If when eating strawberry jam, it is found that the strawberry jam has become thinner or even has an odor, it is not recommended to eat it at this time.
Homemade strawberry jam can be stored in the refrigerator, because strawberries contain a lot of water, which is easy to breed bacteria and even deteriorate. The low temperature in the refrigerator can inhibit the growth of bacteria in strawberry jam and prolong the storage time.
When preserving strawberry jam, if you can make vacuum packaging, you can put strawberry jam in vacuum packaging, which can prolong the shelf life.
