I would ignore the comments about cooking dairy at high heat. This is the same argument the proponents of raw milk are constantly harping about and it is ridiculous. The plain fact is that milk, except for human, has some compounds that are easier for humans to digest if it has been "cooked" and it is certainly safer if it has been pasteurized.
Cooking at the heat in a Thermomix is not high and won't "damage" the molecules - the only thing that changes are the enzymes that determine how the compounds in the milk that consist of molecules are held together.
People all over the world have been making cheese for thousands of years and almost all require heating before processing. Ricotta, which is one of the easiest cheeses to digest, comes from cooking the whey, left over from cheesemaking, at a fairly high temp so the curds form.
As far as juicing is concerned, molecules are far too small to be affected by the action of any juicer. The Champion juicers, that have been popular with the health food crowd for decades, pulverizes the entire fruit, skin and all and every health food store that I know of has at least one and they are very serious about the benefits of juices.
