Why You Should Never Put Tomatoes in the Fridge!

TL;DR

Refrigerating tomatoes reduces their flavor because it alters gene expression and reduces aroma compounds.

Transcript

♪♪♪ You may have been told that putting tomatoes in your fridge will ruin them. It turns out, that’s kind of true. Scientists have shown that reducing a tomato’s temperature to below 20°C alters its gene expression, which in turn reduces its yummy tomato smell. So putting tomatoes in the fridge actually does make a lot of their ripe, juicy flavor d... Read More

Key Insights

• 😑 Reducing the temperature of tomatoes below 20°C changes their gene expression and reduces aroma compound production, leading to flavor loss.
• 👃 Flavor is a combination of taste and smell, with scent being the largest determinant of flavor.
• 🙅 Refrigeration halts the ripening process of fruits, which affects their flavor.
• 🍃 Ripe fruits should be left on the counter until fully ripe before refrigerating to maintain flavor.
• 🏁 Colorful tomatoes, rather than the rosiest red ones, tend to have better taste.
• 😑 Changes in gene expression and molecule synthesis in tomatoes may be an evolutionary response to conserve energy in cold temperatures.
• 👅 Refrigerating ripe tomatoes results in a loss of aroma compounds, not a change in taste components like sugar and acid levels.

Questions & Answers

Q: Why does putting tomatoes in the fridge reduce their flavor?

Refrigerating tomatoes alters their gene expression, resulting in a reduction of aroma compounds, which are crucial for flavor.

Q: What determines the flavor of tomatoes?

The flavor of tomatoes comes from the combination of sugars, acids, and aroma compounds present in the fruit.

Q: Can the loss of flavor in tomatoes be reversed by taking them out of the fridge?

While removing chilled tomatoes from the fridge can improve their flavor, it doesn't fully restore the original taste.

Q: Is it only tomatoes that lose flavor when refrigerated?

No, other ripe fruits may also experience cold-induced flavor loss because lower temperatures impede the production of aroma compounds.

Summary & Key Takeaways

• Refrigerating tomatoes reduces their yummy flavor because it changes their gene expression, resulting in fewer aroma compounds.

• The taste of tomatoes is determined by a combination of sugars, acids, and aroma compounds.

• Placing tomatoes in the fridge decreases the production of aroma compounds, leading to a loss of flavor.
