Consumers may soon be able to go for longer between milk-buying trips. That's because Brazilian company Agrindus hopes to start marketing plastic milk bottles that use embedded silver nanoparticles to kill bacteria. Grade A pasteurized fresh whole milk packaged in those bottles can reportedly last for up to 15 days, as opposed to the usual seven.

The technology was developed by partner company Nanox, and involves first coating silica ceramic particles with silver nanoparticles. This reportedly has a synergistic effect, with the silica boosting the antimicrobial properties of the silver.

Those coated particles take the form of a powder that is subsequently mixed into liquid polyethylene. Using blow- or injection-molding, that plastic is then made into bottles which Agrindus plans to sell to dairy goods companies. The particles can also be used to make milk bags, which should extend shelf life from four to 10 days.

    Oh YEAH! I remember that as well. I think I was about 8 years old, when the Pennsylvania version of the FDA put a stop to it. It suddenly became a violation of state law for a farmer to sell raw milk to anyone other than a processing plant.

    The flavor? Raw milk was all I knew. Rich, wholesome, and actually somewhat filling. The pasteurized stuff? Mehhh - they took all the goodness away. The cream was gone. The flavor was gone. It was like drinking a glass of water.

    THEN they came out with skim milk, and 2% and 1%. Crazy shit. If you want a glass of water, there's the tap. If you want milk, there's the cow. Jeez, Louise, all the government ever did with milk, was to piss me off. Well - government and middle men in the industry. Steal my cream from my milk, then try to sell it to me again in some other form, like cheese. Bunch of arsewipes.

    I used to get nonraw milk here in Quebec, in glass bottles. It was pasteurized but not homogenized. It's the homogenisation that prevents the cream from separating. SO the cream was on top, and it tasted good.

    When the industry switched to cartons instead of bottles, apparently to eliminate the trouble of collecting and cleaning the bottles for reuse, we ended up with the uniform stuff you describe.

    Except we still don't have bovine growth hormones in our milk. Such things are banned in Quebec. Milk here is relatively pure.

    How revealing that you think the government, rather than free market forces, forced dairies to sell skim milk. Must have been the UN enforcing a world-wide production quota with their black helicopters and skim-ops special forces teams.
