Costco has 2 types of Vanilla organic soy milk - one is kept without any cooling with an expiry date after a year, the other one is kept refrigerated, with the same expiry as regular milk. What's the difference between these two?
One is cold, vile, overly sweeted bean juice. The other is room temperature, vile, overly sweetened bean juice.
I believe in French it's called making cheeseWhen I was in France, they had milk cartons that were processed in a way that they could sit without refrigeration for very extended periods.
At the same time, I discovered that if you don't wash eggs after they are taken from the nest that they have a natural protective covering and will last for weeks unrefrigerated. I was really surprised. This is all posted in an old thread.I believe in French it's called making cheese
Alternatively you can get sterilized milk which is completely disgusting but it's the only thing you can get in countries that are too hot for cows.
Breast milk can be stored in the freezer up to 6 months with those ziplock like special plastic bags. My wife stored it in the refrigerator for sometime, but my in-laws couldn't imagine the concept of feeding the baby with few months old milk. To keep them happy, we ended up throwing away the milk :(
The simple answer is that the soy milk in the fridge is hasn't been processed for long-term storage, while the shelf milk has. See the link below for the processing they do in order to get this to work.
By the way, soy milk is delicious! But only the unsweetened kind. :)
powdered milk keeps in the cupboard just fine
