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.

You're fortunate you are able to consume it so quickly. I may have a gallon go bad before I am done with it. I only add milk to coffee, and sometimes for a bowl of cereal or when a recipe calls for it. I've never been much of a milk drinker simply because I need to consume it daily and I don't always have the taste for it. When I want it, it's gone bad or I don't have any. And yes I can buy a smaller container, but it seems I need something that is 3/4th a gallon as opposed to half or a full gallon... packaging costs more, to get a quart and a half gallon, so I end up wasting some of the full simply because it is more cost effective to be a horrible person in that way.
I used to mix it with protein powder, but found that unless I very quickly, and very thoroughly, cleaned out that glass I mixed the power with the milk in -- THAT goes bad. Yuck. Using water was far cleaner and easier to take care of if I did not have the time to actually scrub out the shaker or something. I guess that's a 1st world inconvenience if I am unable to appropriately clean a reusable container immediately after taking a swig of protein powder after excercising. Sometimes, there isn't time to do the right thing as far as dish maintenance is concerned, when you are at work and heading to a meeting.
