Hello, I'm a fruit expert with a passion for berries, especially raspberries. They're incredibly delicate and delicious, but unfortunately, they do have a limited shelf life.

How to Tell if Raspberries are Bad

Raspberries, like most fruits, are perishable and will eventually go bad. Here are some signs to look out for:

* Mold: This is the most obvious sign. Mold will appear as fuzzy white, gray, or black spots on the raspberries.
* Softness: Raspberries should be firm and slightly springy when you gently press them. If they feel mushy or soft, they've likely started to spoil.
* Discoloration: Fresh raspberries should be bright red, purple, or even a deep pink. If they turn brown, gray, or have dark patches, they're starting to deteriorate.
* Smell: Spoiled raspberries will have a sour, fermented smell. This is a strong indication they are no longer good to eat.
* Juice: Raspberries that have gone bad will often release a lot of juice, and this juice will have a sour or unpleasant smell.

Factors Affecting Raspberry Shelf Life

Several factors can affect how long raspberries will last:

* Ripeness: Ripe raspberries will spoil faster than unripe ones.
* Storage: The way you store your raspberries can significantly impact their shelf life.
* Temperature: Raspberries are very sensitive to heat. Warm temperatures will cause them to spoil much faster.
* Humidity: High humidity can cause mold to grow on raspberries.
* Exposure to air: Raspberries should be stored in airtight containers or wrapped tightly to prevent them from drying out and spoiling.

**How to Store Raspberries to Extend Shelf Life**

* Refrigerator: This is the best way to store raspberries. Store them in a sealed container or plastic bag in the refrigerator, and they should last up to 5 days.
* Freezing: You can freeze raspberries to preserve them for longer. Freeze them in a single layer on a baking sheet, then transfer them to a freezer-safe bag or container. Frozen raspberries can last for up to 12 months.

Preventing Spoilage

* Inspect: When you buy raspberries, carefully inspect them for any signs of spoilage.
* Store correctly: Store raspberries in the refrigerator as soon as you get them home.
* Use within a few days: Even in the refrigerator, raspberries will only last for a few days.

In Conclusion

Raspberries are a delicious and healthy fruit, but they have a short shelf life. By being aware of the signs of spoilage and following proper storage guidelines, you can enjoy fresh, flavorful raspberries for longer.

If you're unsure about the quality of your raspberries, it's always best to err on the side of caution and discard them. Eating spoiled raspberries can cause stomach upset and other health problems.
