How to stop apples from browning in lunch box

School time is upon us, and so too is the challenge of keeping sliced apples from going brown in a child's lunchbox before recess.

The sliced fruit battle has baffled parents for years, but there are simple ways to keep the crunch and nutrition in the playtime snack.

According to Scientific American, apples brown because when the skin is broken, oxygen causes the cells to oxidise - effectively "rusting" the fruit.

While the browned face is harmless, it doesn't look appealing, nor does it taste as good.

Here are some tips to keeping apple slices deliciously golden and crisp in a lunchbox.

Rubber bands, air-tight containers, we've tried them all.

Citrus

A squeeze of lemon, lime and even pineapple juice has been proven to keep apples looking their finest. Coat the segment in a splash of your child's preferred tangy taste and store them in a sealed container in the fridge. Apples stay crisp for up to five days using this method.

Ginger Ale

A quick soak in ginger ale prevents the apple from browning, and doesn't affect the flavour, despite the soft drink's distinct taste. The method does add sugar to the apple, however, so bear that in mind if you're attempting to quell the post-sugar hyper-activeness.

Soaking apples in a range of liquids has been proven to prevent browning.

Salt water

A mix of half a teaspoon of salt in a litre of water for five minutes will prevent the flesh of the fruit from spoiling. Alternatively, you can use vitamin C powder (known as ascorbic acid) to add that extra kick of nutrition. This method can keep apples from browning (with refrigeration) for up to a week.

Rubber band

Because oxygen causes the apple to brown, holding together the slices with a rubber band is a tried and tested method, and one circulating TikTok at the moment.

It works without compromising the taste, or taking up time soaking the fruit. It's also a sweet way to uniquely pack a lunch box, so brownie points for presentation.

Happy snacking.

A user on Reddit detailed their method, writing: "I slice down opposite sides from top to bottom just on either side of the core. Then I hold those pieces back on and cut the same on the other 2 sides. If you're looking down from the top you cut like # with the core in the middle. You end up with 8 slices and the core."

"Hold them all together in the shape of an apple and put a rubber band around the whole thing. Since air can't easily get to the cut faces they don't oxidise."

Happy snacking.
