I'm pretty certain it is still raw in every sense. That kind of color change is usually from oxidation. It's not hard to imagine that the HPP process (which involves pressure) might accelerate oxidation. I have an on going research project to try to understand how oxidation affects the quality of meat. I haven't come to any conclusions yet but I certainly agree that grayish look isn't very appealing and indicates some kind of change in the meat.There are three pathogen-free guaranteed foods, all use the High Pressure Processing process. In Canada, NV is the only one. But in the States, the other two are Primal and Stella & Chewy's. And I've used all of them. And ALL of the "HPP" foods are gray and dry. Honestly, I think the HPP alters the food in some way so that it's not exactly raw. They say it's raw, they call it raw... but I'm not convinced it's actually raw.And the kitties SO prefer the actual, juicy raw food.
