so are you talking about cooking the meat then freezing it? which if the meat has already been bought frozen the defrosted and cooked again is not safe to do, and if you did you would of course have to cook it to well done (which again wil lose you a ot of protein) to be sure to be rid of all the bacteria because freezing temprature does not kill as i think you will know, it only puts it into a sleep like state.
If meat would not eventually break down through time why is there a certain timescale in which to use them as a frozen product?
