SUMMARY

Costco offers two types of Vanilla organic soy milk: one refrigerated and one shelf-stable. The refrigerated soy milk has not undergone long-term storage processing, while the shelf-stable version utilizes aseptic processing, allowing it to remain unrefrigerated for extended periods. The shelf-stable soy milk has a longer expiry date, making it a convenient backup option. Nutritional loss occurs during the flash heating process used for shelf-stable milk, but it remains a viable alternative for those needing long-lasting dairy substitutes.

PREREQUISITES
  • Understanding of aseptic processing techniques
  • Knowledge of nutritional differences in milk processing
  • Familiarity with soy milk production methods
  • Awareness of food storage practices and expiry dates
NEXT STEPS
  • Research aseptic processing methods in food preservation
  • Learn about the nutritional impact of flash heating on soy milk
  • Explore alternatives to dairy milk, focusing on plant-based options
  • Investigate long-term storage solutions for perishable items
USEFUL FOR

Health-conscious consumers, food scientists, and anyone interested in plant-based dietary alternatives will benefit from this discussion.

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.
 
maybe one is sealed up tighter?
 
When I was in France, they had milk cartons that were processed in a way that they could sit without refrigeration for very extended periods.

Buwahaha
 
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 :(

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.

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.

not sure how much vitamin C is in breast milk, but I'm pretty sure freezing will destroy most of it. not to say that the diet would be so one-sourced at that point, but simply that freezing loses something nutritionally.
 
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. :)

Thanks for the link. So the flash heating process does cause to loose some nutrients, but better than other sterilization methods.

I use this milk as a backup, mainly because of it's long expiry date. On a monday morning you open the refrigerator, the regular milk bottle is empty or turned bad, kids are hungry...starving...screaming...

Yeah but why not use something that's healthier for the body and better for the planet? :)
