Not all, but yes, some components are inevitably lost in the drying process. There’s a reason that dried fruit is often treated with sulphur dioxide as a preservative. Of course, preserving the colour doesn’t prevent the loss of large amounts of essential nutrients like vitamin C. Fresh is best whenever possible.
Wolves have been observed to subsist on almost exclusively blueberries during the height of the season in Yellowstone, so I’d say the glyphosate residue in the flour is much more of a risk than whatever fruit is in the middle.
