Expiration & Storage Tips
When does raspberry jam expire?
For an unopened jar of commercially prepared raspberry jam, it can last up to 1 year past the 'Best By' date printed on the jar. Once opened, raspberry jam should be consumed within 6 to 12 months if stored in the refrigerator. If you freeze the raspberry jam, it can last indefinitely, but for the best quality, use it within 12 months.
How do you tell if raspberry jam is bad?
To identify if the raspberry jam has gone bad, first smell it. If it has an off smell, similar to fermented, it is a sign that the jam has gone bad. Look for any visible mold on the surface. You may also find a change in color and a lumpy texture which indicates the spoilage. Lastly, if the lid of the jar appears bloated or if the jam spews out upon opening it, it is not safe to consume.
Tips for storing raspberry jam to extend shelf life
• Store the raspberry jam in cool, dark, and dry places prior to opening. Temperate storage conditions normally help extend the shelf life of the product.
• After opening the raspberry jam, make sure to refrigerate it. Keeping it in the refrigerator wards off bacterial growth and helps maintain its freshness for longer.
• If you wish to extend the shelf life, consider freezing the jam. You can freeze it in the original jar or an airtight container. Just make sure not to overfill, as the jam expands as it freezes.
• Always use a clean spoon to scoop the jam. Contamination by food particles can shorten the lifespan of the jam.
• Consider small batches if you make homemade raspberry jam. They not only retain a fresher taste but also reduce the risk of spoilage.
