A food dehydrator is a great asset to any kitchen, as it can preserve food that you would more than likely throw away. It works by drying out, ‘dehydrating’, produce. You might have already come across some dehydrated food before, from berries in your cereal to snacking on dried apricots. You can either dehydrate your food and eat it straight away or save it for later and rehydrate it when you need to. The act of dehydrating food is similar to that of pickling or ‘canning’ food. It preserves it and seals in the nutrients. Before the invention of these handy machines, dehydration could be done outside in the sun; thankfully the process has sped up and is much easier to achieve great results.\r
