Is it true that lettuce keeps longer if it is not shredded?

Question

I like to cut the lettuce into and then chop it. Soak in ice water and enjoy. But it doesn't keep very long. They say it should be torn in to. But i don't like it that way, I like it shredded?
So is it true that it makes a difference weather it is torn or shredded with a knife?

Answer 1

Yes, it is true. The less you handle lettuce the longer it will last. As soon as you put water on lettuce a process called oxidation begins. That's why you see brown "rust" spots on the lettuce.
Keep the lettuce in an air-tight container (or plastic bag) and use only what you'll need for that day or that meal. Store the rest in the crisper, untouched and unwashed.
Hope that helps!

Answer 2

Lettuce is better when torn. You can use a plastic knife (there are some specifically made for lettuce)to shred it, and it will stay fresh longer than if you use a metal knife (somehow the metal reacts with the minerals in the lettuce and causes it to brown faster). For the longest lasting lettuce do not remove the core and do not store the lettuce in a plastic bag. A lettuce keeper is a plastic bowl with an insert that has a point on it. The lettuce core is pushed onto the point, and none of the leaves are touching the plastic bowl.

I don't think this is the best idea. One goldfish alone, when it becomes fully grown, will need a 20 gallon. INCLUDING filter. I suggest getting a big, plastic pond, which is about 30 gallons/90 litres (I think) and it will be enough room for the two goldfish at their sizes right now. I'm guessing they're between 1-3 inches? You do not need any gravel, because it is easier to clean without it, but I would suggest getting a filter, and maybe a couple of plants for them to hide in and help keep the water clean. If you want gravel, try using large, smooth river stones: they're big enough so the fish cannot bury in them or eat them, they look natural, and they're easier to clean. You can always buy some aquarium heaters, add them if necessary in the winter to keep the water from freezing, or at a reasonable temperature. Even if the pond freezes over, fish may "hibernate" at the bottom of the pond where the water is a bit warmer. But do consider a heater for the winter. I hope this was helpful to you, and have fun caring for your fish :)

I think it does have something to do with the metal of the knife, in which case you could always use a plastic knife! Personally I find ripping the lettuce apart with my bare hands satisfying ^-^ grrrrr!

Or you could always just cut what you need at the time instead of shredding it all in advance, or buy smaller lettuces!

Frax ¬_¬

Answer 5

The metal in the knife causes the lettuce to turn brown more quickly. I cannot tell you exactly what it is, but I know that it is the metal. If you tear it up by hand it does take longer, but it will last you much longer as well. Sorry I cannot tell you exactly what metal it is.

Answer 6

It will last longer if it is ripped as the cell will part where they are weakest whilst when you cut them they break open.
Peel the amount of leaves you want to use and soak them, and at the last minute shred.

Answer 7

It will last even longer if you don't use a metal knife,you can get lettuce knives that are plastic,the metal makes them go brown.Took 20yrs to find that out.

Answer 8

yeah it will stay good longer if its kept whole i worked at wendys and the chopped lettuce was only good for a day in the walk in then it was thrown out

Answer 9

Yes it is true I am not sure why but I have noticed it when I do it

Answer 10

yes it's true.
