Raisins may expire 9 months after opening. Once opened, they should be kept in a refrigerator in a sealed container for maximum freshness.
Raisins are safe to consume after 9 months in the refrigerator, but the flavor and texture will not be ideal, and the nutrient content will degrade. Raisins can be added to cold or hot cereal, baked goods and even savory dishes, and they can be eaten on their own in place of sweets. They are naturally high in potassium and fiber, and they keep well without refrigeration, so they make good snacks for both kids and adults.
