A dehydrated fruit has all the fibre and vitamins as the regular presentation of the fruit. It just tastes sweeter due to the fact that the sugar is still there but there is less water. There is an abundant supply of vitamins in pineapple, all of which are retained in the dehydrated fruit with the possible exception of vitamin c which is known to break down very quickly after harvest. Vitamins include C, A and E as well as B group vitamins Thiamine and Folates.
