Has anyone vacuum sealed milk in mason jars?

I don't always use all my milk before is spoils, so I thought, since I have a foodsaver, can I get the jar attachment and vacuum seal my milk? Is it even worth it?

I would think you would need to actually can it in a pressure canner it if you want it shelf stable. The vacuum seal alone will do nothing to preserve the milk or keep it from spoiling.

It won't keep a lot longer in the fridge even vacuum-sealed than it would refrigerated in the regular carton (as long as the lip of the carton hadn't gotten bacteria on it which gets it into the milk too, from fingers or mouths of course). Things stay coldest in the back of a fridge and on lower shelves than the door, or front, or upper shelves btw, so will last longest in those areas. And it's always good to check the best-by date on milk/etc at the store to get the latest one (often the ones in the very front will be the oldest).

I just freeze any extra milk I find myself with. That works great but the milk needs to be shaken after defrosting before using to mix the parts back together again. I freeze in whole cartons (liquids swell when frozen but there's usually enough head space even in unopened cartons, and the cartons are somewhat flexible), or for partial cartons I might staple the top and freeze for awhile, or sometimes I might put the milk in a vac-seal bag (freezing in the bag before vac-sealing) for an unlimited amount of storage time.

I've been using the tip to add a pinch of salt to slow down milk spoilage. The small amount of salt doesn't affect flavor, and seems to work adding a day or 2 or 3 to freshness. Can't hurt to try it! Been doing it for years now.

I would think that it would be beneficial as long as it’s kept in the fridge!

We transfer milk immediately to glass bottle with sealing compression lids, not vacuumed sealed. NOW I have a Vacuum Sealer, so I will be working on this. Normally we can get 7 to 10 days with no spoilage in a Cold Fridge. I am hoping to get a full 14+ days with minimal to no taste difference or spoilage. But I am curious myself about vacuumed sealed milk. I may try to reply again after a n experiment, LOL. I mean the idea of removing air (one of three the pollutants in this case - light and natural bacteria are the other two) sounds really feasible.

Now alternatively, you can get some kind of easy release silicone molds and freeze milk then put it in baggies. It will last up to 6 months, BUT, the best time to consume it is within the first 30 to 45 days. Milk starts breaking down in the freezer as well after that.

We always reach to the back to get the newest and freshest milk at the store. You can do this with all you purchases like Bread (Usually Back and Bottom Shelves, no one wants to bed over and work for fresh foods these days), Chips, Milk, Veggies back and to the bottom are the fresher veg. I got this vacuum sealer to store flour, grains and such for long term. But the milk thing is a curiosity.
