Ultra Pasteurized milk is milk that is flash heated to 275F ( 135C) for 2-54 seconds in order to kill bacterial endospores. This is done to make the milk “shelf stable” requiring no refrigeration. A product in the United States called Dean’s Ultra- pasteurized Heavy Whipping Cream falls under this designation although Organic Valley also uses this on some of their brands according to their website.
My question: Does the flash heat destroy just bacteria or does it affect nutrients found in dairy, particularly cream and does it alter the proteins enough in an attempt to become stable. It seems every time we develop a process for creating shelf stable food products we create some form of downstream harm. I already stay consistently A2 dairy as much as possible to avoid certain caseins found in A1 dairy.
I have looked through the forums and cannot find an answer. There seems to be little if any difference in micronutrients but I could find absolutely nothing about how lipids and proteins might be affected. There is a book that I might buy but it is a 1988 publication.

Looking forward to learning about this.
