Today I am sharing the easiest method for keeping your apple slices from oxidizing. This is just the fancy name we use for turning brown. If you’ve ever eaten an apple before, you will know that if the flesh (insides) of the apple come in contact with air, it naturally will start to turn brown. This is totally normal!

And while the apples taste exactly the same, most people won’t eat them. Brown apples equates with gross apples, which doesn’t have to be the case. It’s just unappealing. So, what’s the solution?

Preventing Apples from Turning Brown with Salt Water

The answer is water and salt! While there are many methods online that state they work (like plain water, lemon juice, lemon juice and water, sprite, etc.) I have found the method that works the very best for me is salt and water!

Make Salt Water

Here’s how to do it:

  • Take 2 cups of cold water and dissolve it with
  • 1 teaspoon of sea salt

Soak Apples 10 Minutes

After the salt is all dissolved, take your sliced apples and soak them in this mixture for 10 minutes, stirring occasionally so all sides of the cut apple get exposed to the salt water.


After the 10 minutes have elapsed, drain the apples, then rinse well. Serve as desired or store in plastic bags in the fridge for up to 10 days. This is the longest I have kept sliced apples in the fridge with them staying freshest. I wouldn’t recommend going beyond 10 days, not because the apples will start to turn brown but because they will start breaking down slightly.

It’s a fantastic solution for those of us who are still packing school lunch for our kiddos. Cut up a bunch of apples at the beginning of the week and prevent the apples from turning brown using our saltwater solution, portion all the apples out into baggies or other containers and then grab and go each day during the week.

Another Solution: Honey!

Honey dissolved into warm water can also prevent apple oxidation. Use the same method:

  • 1 teaspoon honey dissolved in
  • 2 cups warm water.

Add in the sliced apples for 10 minutes. No need to rinse since the honey is sweet! Enjoy or store for later.
