?????? I drink organic skim milk. I’m waiting for someone to tell me why it lasts ten times longer than non-organic milk? Plain and simple question.

It is due to UHT processing, i.e. ultra high temperature pasturization.

I think that SA article is wrong. I believe regular pasteurized milk in the supermarket is marked with a ‘sell by’, not an expiration, date—and it’s good for up to 10 days after the sell-by date.

I assume because there’s no fat in it.
