Store-bought jam or jelly can typically be kept in the fridge for several weeks after it has been opened. The exact duration of freshness depends on the type of jam/jelly, its ingredients, and the storage conditions.
As a general guideline:
Regular fruit jam or jelly: Once opened, it can last in the refrigerator for about 4 to 6 weeks. Always check the label for any specific storage instructions provided by the manufacturer.
Low-sugar or no-sugar-added jam/jelly: These may have a shorter shelf life after opening, usually around 2 to 3 weeks, due to the reduced sugar content.
To maximize the shelf life of opened jam/jelly, follow these tips:
- Always reseal the jar tightly after use to prevent air from entering and spoilage.
- Use a clean, dry spoon to scoop out the jam/jelly to avoid contamination.
- Store the jar in the refrigerator, as the cold temperature helps slow down bacterial growth and preserve the quality of the product.
If you notice any signs of spoilage, such as mold, an off odor, or unusual texture, discard the jam/jelly immediately, as consuming spoiled food can lead to foodborne illness.
Additionally, some jam/jelly products may have specific storage instructions on their labels, so it's a good idea to check for any guidance provided by the manufacturer. Always use your best judgment and senses (sight, smell, and taste) to assess the quality and safety of any food item, especially after it has been opened and stored for some time.
