The humble plum is a staple in many a fruit bowl, and its sweet, juicy flesh is a delight to many. But have you ever wondered what happens to those plums when they’re left in the refrigerator? Will they continue to ripen, or will they become mushy and unappetizing? In this comprehensive guide, we’ll delve into the world of plum ripening and explore the answers to these questions.
As we all know, plums are a type of stone fruit that are typically harvested when they’re green and unripe. They then undergo a process called “ripening,” where they turn from green to red, yellow, or purple, depending on the variety. This process is triggered by a combination of factors, including ethylene production, temperature, and humidity. But what happens when plums are stored in the refrigerator? Will they continue to ripen, or will they slow down or even stop the ripening process?
Ripening Process of Plums
The ripening process of plums is a complex one, involving a series of biochemical reactions that ultimately lead to the breakdown of starches and the production of sugars. This process is triggered by the production of ethylene gas, a natural plant hormone that stimulates fruit ripening. As plums ripen, they produce more and more ethylene, which in turn triggers a series of reactions that break down the starches and convert them into sugars.
But what happens when plums are stored in the refrigerator? The cold temperature slows down the ripening process, but it doesn’t stop it entirely. In fact, refrigeration can actually help to prolong the shelf life of plums by slowing down the production of ethylene and reducing the risk of spoilage.
Will Plums Ripen in the Refrigerator?
So, will plums ripen in the refrigerator? The answer is yes, but it depends on several factors. If the plums are already ripe or nearly ripe when they’re stored in the refrigerator, they will continue to ripen slowly. However, if the plums are stored in the refrigerator when they’re still green and unripe, they may not ripen at all or may only ripen slightly.
Here are some factors to consider when storing plums in the refrigerator:
Temperature: The ideal storage temperature for plums is between 32°F and 40°F (0°C and 4°C). Avoid storing plums at temperatures below 32°F (0°C), as this can cause them to become mushy and unappetizing.
Humidity: Plums prefer a humid environment, with a relative humidity of 80-90%. Avoid storing plums in a dry environment, as this can cause them to dry out and become unripe.
Light: Plums prefer indirect light, so avoid storing them in direct sunlight or bright lights. Direct light can cause the plums to become overripe and mushy.
Handling: Handle plums gently to avoid bruising or damaging the fruit. This can cause the plums to become overripe or develop off-flavors.
How to Store Plums in the Refrigerator
So, how do you store plums in the refrigerator to ensure they ripen properly? Here are some tips:
Store plums in a single layer: Avoid stacking plums on top of each other, as this can cause them to become bruised or damaged. Instead, store them in a single layer to allow for good air circulation.
Use a breathable container: Store plums in a breathable container, such as a paper bag or a mesh bag, to allow for good air circulation. Avoid using plastic bags or containers, as these can cause the plums to become overripe and develop off-flavors.
Keep them away from strong-smelling foods: Plums can absorb odors from other foods, so keep them away from strong-smelling foods like onions and garlic.
Check on them regularly: Check on the plums regularly to ensure they’re not overripe or developing off-flavors. Remove any overripe or spoiled plums to prevent them from affecting the others.
Conclusion
In conclusion, plums can ripen in the refrigerator, but it depends on several factors, including temperature, humidity, light, and handling. By following the tips outlined above, you can store plums in the refrigerator and ensure they ripen properly. Remember to check on the plums regularly to ensure they’re not overripe or developing off-flavors. With proper storage and handling, you can enjoy your plums for a longer period and appreciate their sweet, juicy flesh.

FAQs
Will plums ripen in the refrigerator if they’re already ripe?
Yes, plums that are already ripe will continue to ripen slowly in the refrigerator. However, the rate of ripening will slow down significantly compared to plums that are stored at room temperature.
Can I store plums in a plastic bag in the refrigerator?
No, it’s not recommended to store plums in a plastic bag in the refrigerator. Plastic bags can cause the plums to become overripe and develop off-flavors. Instead, use a breathable container or bag to store the plums.
How long can I store plums in the refrigerator?
The shelf life of plums in the refrigerator will depend on several factors, including the variety, ripeness, and storage conditions. Generally, plums can be stored in the refrigerator for 2-4 weeks. However, it’s best to check on them regularly to ensure they’re not overripe or developing off-flavors.
Can I store plums in the freezer?
Yes, plums can be stored in the freezer for up to 6 months. To freeze plums, wash and dry them, then place them in an airtight container or freezer bag. Frozen plums can be used in baked goods, smoothies, and other recipes.
Can I store plums at room temperature?
Yes, plums can be stored at room temperature for up to 3 days. However, it’s best to store them in a cool, dry place away from direct sunlight and heat sources. Plums stored at room temperature will ripen more quickly than those stored in the refrigerator.
