When it comes to storing fruits and vegetables, many of us assume that the refrigerator is the best place to keep them fresh. However, this isn’t always the case. In fact, some types of produce should never be refrigerated, as the cold temperature and humidity can actually cause them to spoil faster or lose their flavor and texture. In this article, we’ll explore the produce that should not go in the refrigerator and provide tips on how to store them properly.
Understanding the Science Behind Produce Storage
Before we dive into the specific types of produce that shouldn’t be refrigerated, it’s essential to understand the science behind produce storage. Fruits and vegetables are made up of a combination of water, carbohydrates, and other compounds that can be affected by temperature, humidity, and light.
Refrigeration can slow down the ripening process of some fruits and vegetables by reducing the production of ethylene gas, a natural ripening agent. However, for some types of produce, refrigeration can actually cause more harm than good. For example, cold temperatures can break down the cell walls of some fruits and vegetables, making them more susceptible to spoilage.
The Role of Ethylene Gas in Produce Storage
Ethylene gas plays a crucial role in the ripening process of fruits and vegetables. As produce ripens, it produces more ethylene gas, which in turn stimulates the production of more ethylene gas, creating a ripening cycle. Refrigeration can slow down this cycle by reducing the production of ethylene gas.
However, some types of produce are more sensitive to ethylene gas than others. For example, fruits like apples and bananas produce more ethylene gas than vegetables like broccoli and carrots. This means that storing these fruits in the refrigerator can actually cause them to ripen faster.
Produce That Should Not Be Refrigerated
Now that we’ve explored the science behind produce storage, let’s take a look at the specific types of produce that should not be refrigerated.
Potatoes
Potatoes should never be refrigerated, as the cold temperature can convert the starches in the potato into sugars, making them sweet and unappetizing. Instead, store potatoes in a cool, dark place with good ventilation. This will help to slow down the ripening process and keep them fresh for longer.
Why Refrigeration Can Be Bad for Potatoes
Refrigeration can be particularly bad for potatoes because it can cause the formation of chlorophyll, which can give the potatoes a greenish tint. This can also make the potatoes more toxic, as chlorophyll can produce toxic compounds when it’s exposed to light.
Onions
Like potatoes, onions should not be refrigerated. The cold temperature and humidity can cause the onions to become soggy and develop off-flavors. Instead, store onions in a cool, dry place with good ventilation.
How to Store Onions Properly
To store onions properly, make sure to keep them away from direct sunlight and moisture. You can store them in a paper bag or a breathable container, such as a mesh bag or a wooden crate. This will help to keep the onions dry and fresh for longer.
Garlic
Garlic is another type of produce that should not be refrigerated. The cold temperature can cause the garlic to sprout, which can make it less flavorful and less potent. Instead, store garlic in a cool, dry place with good ventilation.

Tomatoes
Tomatoes should not be refrigerated, as the cold temperature can cause the tomatoes to lose their flavor and texture. Instead, store tomatoes at room temperature, away from direct sunlight.
Why Refrigeration Can Be Bad for Tomatoes
Refrigeration can be particularly bad for tomatoes because it can cause the formation of a gas called lycopene, which can give the tomatoes a mealy texture. This can also make the tomatoes less flavorful, as the cold temperature can break down the cell walls of the tomato.
Squash
Squash, including acorn squash and zucchini, should not be refrigerated. The cold temperature can cause the squash to become soggy and develop off-flavors. Instead, store squash at room temperature, away from direct sunlight.

Produce That Can Be Refrigerated, But with Caution
While some types of produce should not be refrigerated, others can be refrigerated, but with caution.
Apples
Apples can be refrigerated, but they should be stored separately from other fruits and vegetables. This is because apples produce a lot of ethylene gas, which can cause other fruits and vegetables to ripen faster.
