How do you keep lettuce heads from turning brown?
Keeping this in view, why is my lettuce going brown?
Oxidation. The most common reason for browning on lettuce is a chemical process known as oxidation. Enzymes activated by cutting the leaves or stems produce compounds that result in brown stains, especially at the base or anywhere the leaves are damaged during harvest and storage.
Likewise, why does lettuce turn brown when you cut it? The result is a reaction that oxidizes the polyphenols and allows them to link up with each other to produce a brown pigment. When lettuce leaves are torn, some cells are damaged and the browning reaction begins.
Subsequently, question is, how do you keep head lettuce fresh?
Wrap the entire head in a paper towel, place in a plastic bag, and store in the fridge. Pull off leaves or cut off chunks of lettuce as you need them, rewrap remaining lettuce in paper towel and return to plastic bag. Iceberg will keep fresh for a very long time if you store it correctly!
How do you keep lettuce crisp after washing?
After washing your lettuce leaves, spin them dry and place the slightly damp greens in a container. A container is best, but you can use a plastic bag if you keep a corner open (to allow some airflow in). Add a few paper towels to absorb excess moisture and you'll be able to store these greens for seven to 10 days.
