Sliced apples are a quick, healthy snack—but they brown fast once cut. That unappetizing color change happens because of oxidation: when the apple’s flesh is exposed to air, enzymes react and turn it brown.
While the browning doesn’t affect taste or safety, it’s not exactly appealing.
The good news? There are simple ways to slow it down and keep your apples looking fresh and crisp. Whether you’re packing a lunch or prepping a fruit platter, these steps will help your apples stay bright longer.
Step 1: Choose Fresh, Firm Apples
Start with crisp, fresh apples. Some varieties brown more slowly than others—like Honeycrisp, Gala, or Empire—so if you’re slicing ahead of time, choose one of those. Avoid bruised or overly ripe apples, as they tend to brown faster.
A quick tip: If you’re slicing a mix of apples, treat them all the same way to keep their appearance consistent.
Step 2: Use an Acid to Slow Browning
Acids help stop the oxidation process. Right after slicing, coat your apple slices in one of these:
- Lemon juice (most effective, but tangy)
- Pineapple juice (sweeter, kid-friendly option)
- Orange juice or lime juice
- Vinegar + water (1 tablespoon vinegar to 1 cup water — works but can affect the taste)
Toss the apple slices in the juice or dip them for a few seconds. Make sure all surfaces are coated.
Step 3: Try a Salt Water Soak (Yes, It Works)
Saltwater is another easy method that won’t alter the flavor much. How to do it:
Mix ½ teaspoon of salt into 1 cup of cold water. Soak the apple slices for 3–5 minutes, then drain and rinse them briefly in fresh water. This method works well for meal prep or school lunches.
Step 4: Keep Them Cold and Covered
After treating your apples, store them in an airtight container in the fridge. This slows the browning process even more. You can also cover them tightly with plastic wrap if you’re serving them soon.
Bonus tip: If you’re packing apples to go, add a damp paper towel over the slices before sealing the container—this helps maintain moisture.
Step 5: Use Honey Water for a Natural Fix
Want a natural, sweet way to prevent browning?
Try this: Mix 2 tablespoons of honey into 1 cup of water and soak the apple slices for about 30 seconds. Honey contains a compound that slows down oxidation naturally—plus, it adds a hint of sweetness.
