Somebody just make a raw milk website with a couple of Bitcoin payment and delivery options already!
Delivery of raw milk is actually the weak link - if you cannot get and consume it yourself on the same day, you shouldn't drink that stuff at all. There's a REASON that pasteurization exists, and it's not to "filter out blood" but to ensure you get less sick than you could. Most examples here about "it didn't harm me" were about milk consumed the same day or from very nearby - not shipped/delivered. Unless you have a valid business model that involves a "milk man", you're up for trouble once your first customer dies or gets seriously ill (and looking at a few pages about the wonders of raw milk I guess the people drinking the stuff are also the ones that might be of the "If I can still eat it out of the bottle with a spoon and don't need fork + knife, it's still ok!"-type). If you can manage to pick up milk at some nice local farmers and deliver milk from last evening to the doorstep for breakfast - good for you, but then you might be better off in accepting USD and making sure you operate legally.
Once some fanatics from southern Florida start ordering raw milk online with you, I'd recommend you to stay away from that stuff and rather sell drugs on silk road - less chance that a customer dies, or worse - survives and sues you.
At those sorts of temperatures, not only does it kill bacteria, but some proteins also break down. I'm no expert on proteins, but presumably it alters the flavour and makes the milk less nutritious. A couple of other things would be interesting to know:
- what chemical changes occur to the fat content when it's heated?
- what difference is there (if any) in the utility of the milk as an ingredient or raw material of other products? For example: butter, yoghurts, kefirs, and baked goods?
I don't know for sure, but I would speculate that raw milk produces much better results in both cases.
Proteins don't break down, they coagulate. With raw milk they do this in your stomach (pour some hydrochloric acid in a glass of milk and be amazed - that's what happens), with pasteurized milk they (in small amounts) do it before. Also some vitamins don't really get along too well with heat, so they also get destroyed partly. The (often unhealthy) obsession of people with vitamins is left for another thread I hope though...
There's not much happening to the fat when being heated, what changes though is the homogenization treatment that most milk gets to make sure the fat doesn't swim on top after a while but stays in solution. This means the "fat bubbles" are made smaller and stay in solution over the lifetime of the milk.
More info can be found in wikipedia for example, in case you're interested:
http://en.wikipedia.org/wiki/Milk#Processing,
http://en.wikipedia.org/wiki/Pasteurization#Pasteurization_of_milkAs you can also see there, heating milk for a few seconds does NOT suddenly change it's contents and nutritional value completely.
If you use raw milk as ingredient for (especially) cheeses, you need to label them accordingly and again have to be very careful about contamination.
Butter = milk fat, more affected by quality than treatment
cheese = milk protein, see above. Raw milk cheeses exist but if you've seen how cheese is made, you'll also know why a few bacteria more or less won't matter there. Also the way cheese is created is not a very nice environment for germs to begin with.
yoghurt/kefir = more or less milk gone bad - here it might make a difference, but it would probably be far too risky to get a bad strain of bacteria in your milk. I doubt that you'd get really consistent quality out of raw milk and it pays off more to use good quality milk.
baked goods = far longer and higher heated than pasteurization during baking, why should a dozen seconds more matter in the final product?!
Again, it seems you are mixing "raw milk" and "high quality milk" in your mind - every milk on this planet starts as "raw milk" and can be used as such inside a dairy. It mostly isn't and that's for good reasons.
