How do you keep apples from turning black?

To use this method to prevent apples from turning brown, create a water bath for your apple slices with a ratio of 1 tablespoon of lemon juice to 1 cup of water. Soak the apple slices for 3 to 5 minutes, then drain and rinse them. This simple step should keep your apples from browning for several hours.

How do you keep a cut up apple from turning brown?

Here's the short version: The best way to prevent browning is to soak the cut fruit in a saltwater solution (half a teaspoon of kosher salt per cup of water) for 10 minutes, then drain and store until ready to use. The mild salt flavor can be rinsed off with tap water before serving.

How do you preserve apple slices?

Salt water: Use 1/4 teaspoon salt to two cups of water. Soak apple slices in the salt water for a few minutes, then rinse before serving or storing. This brine keeps browning at bay for up to a week. Lemon juice: Tossing cut apples in lemon juice will keep them from browning.

Why does salt water prevent apples from turning brown?

If pigments oxidize, they can change color completely. Salt solution is used as it reduces the amount of water on the surface of the apple through osmosis as the salt has a lower concentration of water, hence water in the apple would move out of the apple, thus slowing down oxidation.
