For loose-leaf lettuce, store it in a sealed container. Line up some paper towels on the bottom of the box, place the leaves, and line more paper towels on top. Remove any wilted or mushy leaves, if any. The storage instruction is straightforward. As long as the package is unopened, simply keep it in the refrigerator.
If you have leftovers, transfer into a container and store it similarly with loose leaf lettuce. As lettuce ages, it starts to wilt. It loses its firm texture and becomes soft. After this, lettuce will turn brown. At this point, you can still use the lettuce before it starts rotting.
For head lettuce, cut out the outer leaves that look wilted or brown. Check the inner leaves. If they look perfectly fine, feel free to use them.
With loose-leaf lettuce, you can do the same if the mushy leaf is just one or two leaves. However, if the damaged parts are massive, better to get rid of it.
When the spoilage gets further away, the leaves will smell off or rotten, or too watery. Lettuce is a perishable and delicate item. It needs proper refrigeration and handling. When it bruises, it also goes bad very quickly. The quality when you buy lettuce determines how long it lasts in your refrigerator. Only buy lettuce that is firm, no brownish spot, or signs of wilting. With proper refrigeration, iceberg lettuce lasts for at least 1 week to 2 or 3 weeks.
Loose-leaf lettuce green and red leaf has the shortest life for around 3 to 7 days. It may still be suitable to eat for a few days passing this date, as long as the pack is unopened.
Once opened, use the remaining within 2 to 3 days. The precise answer to that question depends to a large extent on storage conditions - after purchasing, keep iceberg lettuce refrigerated at all times.
How long can iceberg lettuce be left at room temperature? To maximize the shelf life of iceberg lettuce, refrigerate in a loosely closed plastic bag and do not wash the iceberg lettuce until ready to eat. How long does iceberg lettuce last in the refrigerator? Properly stored, iceberg lettuce will usually keep well for about days in the fridge.
Iceberg and romaine lettuce last the longest, between 7 and 10 days. However, the above is only an approximation and a general guideline of their shelf life. Lettuce can last shorter or longer depending on other different factors.
In this short guide, we will go through shelf life, storage, and signs of spoilage of the most popular kinds of lettuce used every day: butter, leaf looseleaf , iceberg, and romaine.
Butter lettuce, or butterhead, is one of the four main types of annual lettuce that is widely available in the United States. The USDA indicates that butter lettuce is low in sodium, a good source of calcium, iron, and vitamin A. The sweet, tender leaves of butter lettuce are known for making great salads, but its use is great for making other food as well.
Butter lettuce is great for using as layers in spring rolls and wraps. This lettuce has a large, loose head of bright green, curly leaves with a buttery flavor to it. Leaf lettuce is high in nutrition, especially the greener the leaf is. Out of all the four kinds of lettuce listed here, leaf lettuce is the most nutritious variety.
Iceberg is a variety of lettuce with crisp leaves that grows in a spherical shape. This lettuce has a sweet taste and is great to use on burgers and sandwiches. When it comes to nutritional value, iceberg lettuce has very little nutritional value. It provides some calcium, potassium, vitamin C, folate, and fiber.
Therefore, iceberg lettuce is great to eat during hot weather. Romaine lettuce is low in fiber but has a high content of minerals such as calcium, phosphorus, magnesium, and potassium. Unlike other lettuce, romaine lettuce is not used in sandwiches and burgers. Due to its thick leaves, romaine lettuce is more commonly used for grilling, stir-fried, and cooking meals.
Lettuce sold in grocery stores is usually handled by large companies. They harvest and process thousands of lettuce each day. Once you bring the lettuce home, how long it will last will depend on how you store it. For most types of lettuce, the fridge is the best place to make them last the longest. Most kinds of lettuce can last up to 10 days in the refrigerator. For butter lettuce, store them in a sealed plastic bag or in a crisper drawer in the fridge.
