9. Sprinkle salt on the surface of fruits to avoid browning
Especially apples are known for turning brown almost instantly after being cut. This is annoying if you want to prepare a breakfast- or lunch box as you will always be greeted with brown apples (also happens with other fruits).
Salt can deliver another life hack in this situation. Simply submerge the fruits in saltwater, then rinse them off with regular water so there is no salty aftertaste present in the fruits.
Did you know, that the darkening is actually down to some fruits and vegetables oxidizing after coming in contact with oxygen? This is not dangerous but certainly makes fruits much less appetizing.
Never forget to rinse these fruits before you cook or consume them.
