Explain why do tomatoes wilt in the refrigerator?

In short (click here for detailed version)

The cold temperatures of the refrigerator alter the structure of the cell walls of tomatoes, leading to a loss of texture and the development of wilting.

Explain why do tomatoes wilt in the refrigerator?
In detail, for those interested!

Loss of flavor

When stored in the refrigerator, tomatoes can lose their flavor. This phenomenon is due to the reduction in the production of volatile compounds responsible for the characteristic aroma of ripe tomatoes. The cold alters the cell membranes, leading to a decrease in the release of these compounds. Furthermore, the cold inhibits the activity of enzymes responsible for fruit maturation, which can affect the optimal development of flavor. As a result, refrigerated tomatoes may have a less pronounced and less sweet taste than those stored at room temperature.

Modified texture

When tomatoes are stored in the refrigerator, the texture of the flesh can be affected. This change in texture is mainly due to the damage caused by the cold. The cold of the refrigerator can damage the cell walls of tomatoes, causing a deterioration in their texture.

The cell walls of tomatoes contain water, which freezes at temperatures below 0°C. When water freezes, it expands and can puncture the cell walls, leading to a soft and flabby texture of tomatoes after being stored in the refrigerator.

This change in texture is noticeable when handling tomatoes. When touched, refrigerated tomatoes may feel softer and less firm than those stored at room temperature. The flesh may seem more watery and less juicy, which alters the sensory quality of the tomato.

The modified texture of tomatoes after being placed in the refrigerator can be an important element to consider to preserve the organoleptic quality of this fruit.

Change in composition

When tomatoes are stored in the refrigerator, their composition can be altered. Indeed, the cold can cause a transformation of the sugars and acids present in the tomato. This alteration can lead to a decrease in the sweet taste of the tomato, making it less flavorful. Furthermore, the cold can also change the texture of the tomato flesh by making it more floury, which can affect the taste experience when consumed. These changes in composition can therefore negatively impact the overall quality of the tomato once removed from the refrigerator.

Frequently Asked Questions (FAQ)

1

How does cold affect tomatoes in the refrigerator?

The cold temperature of the refrigerator can lead to the degradation of the texture of tomatoes and alter their flavor.

2

Why do tomatoes lose their flavor when refrigerated?

The cold interrupts the maturation process of tomatoes, which can alter the development of their aromatic components responsible for their delicious flavor.

3

Which other vegetables or fruits are sensitive to the cold of the refrigerator in the same way as tomatoes?

Other cold-sensitive fruits such as avocados, bananas, and zucchinis can also undergo undesirable changes in texture and flavor when refrigerated.

4

How long can tomatoes be kept in the refrigerator without being damaged?

Tomatoes can be stored in the refrigerator for a few days without any issues, but for optimal preservation of flavor and texture, it is recommended to store them at room temperature.

5

Are there any techniques to conserve tomatoes for a longer period of time without refrigerating them?

Yes, keeping tomatoes at room temperature, with their stem down, and avoiding storing them near sources of heat helps to optimize their preservation and flavor.
