As a food science expert with extensive knowledge in the field of perishable goods, I can confidently address the question of whether lettuce should be refrigerated. The answer is a resounding yes, and here's why.
Lettuce, a staple in many diets, is known for its perishable nature. This means it doesn't last long before it begins to show signs of decay. The primary reason for this is the high water content in lettuce, which makes it susceptible to rapid spoilage when exposed to room temperature for extended periods.
When you bring lettuce home from the store, it's usually best to refrigerate it immediately. The cold temperature slows down the enzymatic and microbial activities that lead to spoilage. This is not just a matter of taste but also of safety, as spoilage can lead to the growth of harmful bacteria.
The storage lifetime of lettuce can be significantly extended through refrigeration. At room temperature, lettuce can start to wilt and become slimy within a day or two due to the action of enzymes and the multiplication of bacteria. In contrast, when refrigerated, lettuce can last for up to a week or more, depending on the type of lettuce and the conditions within the refrigerator.
It's important to note that even within the refrigerator, lettuce should be stored properly. It should be placed in a plastic bag or container to maintain its moisture level. However, the bag should not be sealed completely as lettuce also needs to breathe. Over-wrapping can cause condensation, which can lead to faster spoilage.
Moreover, the temperature within the refrigerator also matters. The ideal temperature to store lettuce is between 32°F to 41°F (0°C to 5°C). At these temperatures, the respiration rate of the lettuce is reduced, which slows down the aging process.
In addition to temperature, the humidity inside the refrigerator is also crucial. High humidity helps to keep the lettuce crisp. Some modern refrigerators come with a dedicated crisper drawer that can be adjusted to maintain the optimal humidity level for storing vegetables like lettuce.
When it comes to the expiration of lettuce, it's not just about the passage of time but also about the conditions it's stored in. At warmer temperatures, the rate of spoilage accelerates. This is why, even if you've only left lettuce out for a few hours, you might notice it starting to deteriorate.
In conclusion, refrigeration is not just a suggestion but a necessity for preserving the freshness and safety of lettuce. By following proper storage practices, you can enjoy your lettuce for a longer period without worrying about it going bad too quickly.

It is all due to storage lifetime. Lettuce is particularly perishable, compared to many other vegetables. You will get a considerably longer storage lifetime if it is refrigerated, rather than kept at room temperature. ... You can see at warmer temperatures, the lettuce will expire much more quickly.Apr 17, 2013
