| Boilerpipe Text | You’ve been thinking about the apple slices and peanut butter in your lunchbox all morning. But thanks to meetings and conference calls, it’ll be a race against the clock to eat them before they turn brown and mushy. It turns out there are a few ways to keep your favorite healthy snack crisp and fresh longer. Learn how to keep apples from browning with these six easy methods.
Why Do Apples Turn Brown?
Just like
avocados
, brown apples are safe to eat; they’re just less appetizing. Browning (or
enzymatic browning
if you're fancy) is a natural chemical reaction that occurs when oxygen comes in contact with polyphenol oxidase, an enzyme found in various fruits and vegetables. Oxidation can lead to a change in the appearance of fruit, as well as a decrease in flavor and nutrition.Â
If you’re going to slice an apple and eat it immediately, don’t go through the trouble of treating the slices. Just know that the longer they’re exposed, the browner they’ll get. If you’re slicing hours (or even days) in advance, these methods can help it maintain its natural color, at least for a while. To store sliced apples, always use an airtight container or a resealable bag with all the air pushed out of it.
How to Keep Apples from Browning
1. Brush or Dip the Apple Slices in Lemon Juice
It’s the oldest trick in the book. Lemon juice’s high acidity and low pH deactivates the enzyme that causes browning. Essentially, the acid reacts with the enzyme before the enzyme and oxygen have a chance to react with the apple. Ever wonder why store-bought apple slices are always so white and crunchy? They’re often treated with
ascorbic acid
, citric acid or sulfites—lemon juice (another acid) works the same way.
Give the apples a quick spritz of lemon juice, or dilute a few drops of lemon juice in water and soak the apple slices. No fresh lemons? Try bottled lemon juice, lemonade or even orange juice—as long as it’s acidic, it’ll slow browning. Vinegar works too because of its acidity, but it’ll potentially impart a more unpleasant taste than these other alternatives. If you’re freezing farmers market Honeycrisps for a future batch of applesauce or apple bread, lemon juice is your best bet.
Wash and slice the apple.
Fill a small bowl with cold water and the juice of half a lemon.
Dip the slices into the mixture. Eat or store for later.
2. Soak the Slices in Saltwater
You may remember from chemistry that salt is also called sodium chloride. Its namesake chemical components keep oxygen from reaching the surface of the slices. After all, it’s nature’s oldest preservative. Just be super careful not to add *too* much salt. Using ½ teaspoon or less in a cup of water will get the job done without altering the apple’s taste.
Wash and slice the apple.
Dissolve the salt in cold water.
Add the apple slices to the saltwater and let them soak for about 3 to 5 minutes.
Drain, rinse and dry the apples. Eat or store for later.
3. Submerge the Slices in Honey Water
Thanks to a peptide compound found in honey, this method deactivates the browning enzyme. Cook’s Illustrated found that a good soak kept the slices white for more than a day while a 30-second dunk kept browning at bay for eight hours. This trick also works for veggies like potatoes and other fruits like pears. (And it tastes good to boot.)
Wash and slice the apple.
Dissolve 2 tablespoons honey in 1 cup water.
Dunk the slices in honey water for at least 30 seconds and no more than a few minutes.
Remove, rinse and eat or store for later.
4. Submerge the Slices in Liquid
It works like a charm if you don't have any of the other quick fixes on hand. The idea here is that the oxidation process can’t start if the apples aren’t exposed—and they can’t be exposed while in liquid. Some swear by soaking apples for 3 to 5 minutes in a ginger ale or lemon-lime soda that contains citric acid, but we like avoiding the extra sugar and using club soda or water.
Wash and slice the apple.
Fill a bowl with cold water and add the apple slices.
Top the bowl with a paper towel. Once it’s wet, it will submerge the floating slices.
Remove the slices after about 10 to 15 minutes. Dry and enjoy, or shake dry and store for later.
5. Sprinkle the Slices with Ascorbic or Citric Acid Powder
You’ve probably seen packaged sliced apples at your local supermarket, shockingly without a single brown spot. It’s because they’re typically treated with ascorbic acid, aka vitamin C. You can buy
citric acid powder
or
ascorbic acid powder
online or at specialty grocers like Trader Joe’s to do the same at home. A popular brand to search for is
Ball’s Fruit-Fresh Produce Protector
.
Wash and slice the apple.
Sprinkle the powder onto the slices.
Eat within 8 hours.Â
6. Hold the Slices Together with a Rubber Band
Try this trick whenever you’re taking a sliced apple on the go. It protects the slices from air exposure. All you need is a knife and a thick, tight rubber band. (You can try substituting a rubber band for plastic wrap if you can’t find one.)
Wash and slice the apple as you normally would. Don’t throw out the core.
Reassemble the apple around the core.
Wrap the rubber band around the apple to hold the slices in place. Place it in a bag or food storage container, then toss it in your purse, lunchbox or fridge for later.
