You can control just how dehydrated to make it at the low temperature, so you would not rehydrate it as there is no need, so there will not be a study. There is lots of information on thawing frozen fruit and veggies, rupturing the cell walls, thats why they get mushy. There is information on dehydrating at low temperatures to keep vitamins, and enzymes from degrading. Frozen veggies are handy for some, but you have to worry about listeria containation these days, I keep seeing more recalls.
Dehydrating takes some water out so foods can be kept at room temperature longer and are a method for longer storage. Raw dehydrating is done at a low temperature and you can control just how much water you take out, so the food is not even close to as dry as baked, or high temperture dehydration. It would be closer to what a parrot would eat in the wild, when they ate a berry that had fallen to the ground and was a little dryed. When you dehydrate at low temperature you have to keep the items in the fridge after, most of the time.
In humans, there is a controversy over frozen and raw in the raw community. There is controversy over grains in the health community. In my life, I saw tremendous improvement in my daughters life when she quit eating almost all grains, and my husbands health improved after his celiac diagnosis, but before he got sick enough to develope the auto immune disease he was gluten intolerant for years, and looking back you can see now where it affected him throughout his life. So many people require different diets to be healthy, and then parrots ate different diets in the wild. All we can try to do is feed as natural as possible, and because we cant get the exact food the parrot ate we have to do our best with different foods.
I have chosen to stay very low on all grains with my parrots, and even in my own diet, based on many years of research and life experience. Grains are not edible for parrots unless cooked or in a "green state" ( green meaning a state of new budding in a plant, or sprouting from the mature seed,) In the wild any grains they ate were green raw grains which they could digest. I believe raw diets for parrots can be much closer to natural and they are not hard to do at all, I think many believe they are because they dont have the experience and they havent done the research, so they dont know the easy ways to do it. Raw vegetables tend to be able to be at room tempertature for long periods of time, and so can some fruits, like peppers. Cooked grains, can not be out for that long without having all kinds of "bad things" growing on them. Parrots seem to tolerate more than we can eating food that has been sitting out all day, but they also cant tell us if they dont feel tip top some days or what that does to them in the long run.
