if you want to get really technical and compare percentages that really wont make a substantial difference, then yes freze dried is not as good as frozen, and flash frozen comes before frozen in quality as flash freezing freezes the product before cell breakdown occurs, with regular freezing the cell walls break down and release alot of nutrition, in the form of oils. this is easily seen in mysis shrimp, when flash frozen they remain intack and the product is much cleaner, when frozen normaly, the cell walls break down and the mysis shrip get surrounded by a soup like oil, its great for feeding corals, but not the best for some aplications. when we flash freeze the mysis shrimp on the boat, they are alive in the bags on the trays and 60 seconds later they are flashfrozen and preserved.
