What causes apples to brown?
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
How do you keep cut apples fresh?
Mix 1/2 teaspoon kosher salt into 1 cup of cool water until dissolved. Add your sliced apples and soak for about 10 minutes. Drain the apples and store in an airtight container for up to a week. If you’re packing the apples in a lunch box right away, give them a rinse under cool water.

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.
Can I eat brown avocado?
