No, it's totally different. You can't use UHT to make latter or cappucino.

If you try to foam UHT, you will get a clump of horrible bubbles that looks like vomit

I make my own latte and cappuccino at home.

You are right. I tried to foam uht fresh milk this morning.. macam fuk but the fresh milk foam smooth

Uht stand for ultra heat treated. Where can not reach boiling point.
Pasteurisation is the one below boiling point but heated longer. Uht heat few seconds then pancut
