There's no puzzle about what is the best treat for your sweet tooth: real fruit!
But getting kids to choose fruit over the myriad other sweet temptations can be tricky. Here's a sneaky way to make an apple fun, and keep it fresh in a lunch box to boot!
Apples turn brown when they are cut because the enzymes and iron phenols in the fruit oxidize when exposed to air, basically causing the surface of the fruit to "rust." It's a protective mechanism against pests and pathogens, but doesn't really change the taste of the fruit. It's not very pleasing however, and while immersing the fruit (potatoes, bananas and pears, to name a few, are also prone to this "enzymatic bruising") in water or lemon will retard the effect, they can also make the fruit less pleasant to eat.
Try this at home!
