Apples are a favorite snack crunchy, sweet, and full of nutrition. But as soon as you slice them, they start turning brown, which makes them look less appealing. Ever wondered why this happens and how to stop it?
Let’s break it down and learn simple tricks to keep those slices fresh and appetizing!
Why Do Apples Turn Brown?
When you slice or bite an apple, the oxygen in the air reacts with enzymes in the fruit, causing a chemical process called oxidation. This turns the exposed surface brown. While browning doesn’t make the apple unsafe to eat, it can be unappealing, especially in kids’ lunchboxes, party platters, or fruit salads
7 Easy Ways to Keep Apples From Browning
1. Lemon Juice (or Any Citrus Juice)
Citrus juices are rich in vitamin C (ascorbic acid), which slows oxidation.
- Squeeze fresh lemon, lime, or orange juice over your apple slices.
- Alternatively, toss slices in a bowl with diluted lemon juice (1 tbsp juice + 1 cup water).
2. Saltwater Soak
A quick soak in lightly salted water can do wonders.
- Mix 1/2 tsp salt with 1 cup cold water.
- Soak slices for 3–5 minutes, then rinse and store.
3. Honey Water Solution
Honey contains natural compounds that inhibit oxidation.
- Mix 2 tbsp honey with 1 cup water.
- Soak slices for 30 seconds to 1 minute.
4. Use an Airtight Container
Limiting exposure to air helps delay browning.
- Store sliced apples in an airtight container or zip-lock bag.
- Add a paper towel to absorb excess moisture.
5. Refrigeration
Cold slows the oxidation process.
- Store prepared slices in the fridge right away for best results.
6. Pineapple Juice or Apple Juice
Sweet juices like pineapple or apple juice can also help by coating the surface with antioxidants.
- Dip or drizzle slices with juice and refrigerate.
7. Ascorbic Acid Powder or Vitamin C Tablets
Found in the canning section, these are excellent for bulk prep.
- Dissolve in water per packaging instructions and dip slices.
Pro Tip: If you’re prepping apples for a lunchbox or platter, combine two methods—like lemon juice and refrigeration—for best results!
