Actually several years ago I was partnered with someone on a venture to create such a thing -- we had everything set to go . She had years of experience with freeze driers as she was a person who would create custom ordered , commissioned herbal concoctions for holistic vets and human naturapaths . My supplements was to be included as the "everything else" . We had the freeze drier , a unit sold by the company she rented freeze drier space from and we were going to rent floor space , a portion of the facility. Things never got off the ground except for expenses of course ! The unit was moved and installed in a location determined by one of the food inspectors. Then when we called the expert for the go-ahead they questioned why we were situated where we were -- too close to other food which was non-meat and we were definitely freeze drying meat , chicken meat . So we moved it to another location within the distance we had to be from other production . In the moving something jiggled and broke , and then after repair and setting up again discovered that the break caused pressure to be inadequate , so we called in for a top up --- except at this point , like a refrigeration , household included , we could not do this because FREON was now not used --- not in Canada .
So that was the final straw that broke the partner's interest , and that was that ......
However freeze drying is an excellent form for preservation -- same technology as all the food that is used on space stations , emergency supplies , back packing , mountaineering. No nutrition removed. No enzymes destroyed . No heat alteration of fats . Only the moisture content is removed and so there is no bacterial degradation.
The one thing we were worried about is you end up with this teeny bag , with seemingly large price tag because you can't envision how much that bag represents when rehydrated.
I am pretty sure that Orijen has it's freeze dried product out in many locations by now. Orijen
The processing is superior in that you don't need to add preservatives and all nutrients are in tact.
