Why is some dehydrated fruit brown?

Fruit is sugar sugar rich food. In the process of dehydrating it is exposed to heat, which can cause the fruit sugars to brown. However, Dehydrated Co. uses a 'slow and steady' approach to dehydrating our products. This not only ensures that the fruit keep as much of its vibrant colour as possible, but it only ensures that the dehydrated product has a long shelf life.
