unpasteurized whey?

Any chance of an unpasteurized / unheated whey isolate or concentrate? It is well known that whey protein fractions and peptides denature at temperatures customarily used in dairy processing (see e.g. http://books.google.com/books?id=1OhFPZ7tFz8C&pg=PA866#v=onepag...). If we're buying the stuff for the immunoglobulins, etc., we should be confident that they have not been destroyed by processing. A few manufacturers advertise unpasteurized whey protein products, but not in pure form for retail sale (they are inevitably contaminated with synthetic flavors and other additives). Thoughts?

    My thoughts are that whey protein is hard enough to source, let alone non-pasteurized whey protein. While it is an interesting finding that non-pasteurized whey protein is significantly better than pasteurized, I could also say the same thing about all milk products. Pasteurization of dairy products is one of the greatest health threats to the so-called civilized nations of the world and yet almost no government or health organization will admit as much. I only wish there was such a thing commercially available.
