How does pasteurization influence flavor, and which method tends to cause more flavor changes?

Explanation:
Flavor in milk is shaped by heat-dependent changes in aroma compounds. HTST uses a moderate temperature for a short time, which is gentle enough to keep most delicate flavors intact, so it tends to preserve the fresh dairy taste. UHT, on the other hand, applies a much higher temperature, even though briefly, and this higher heat drives reactions that create cooked or toasty notes and can alter or reduce subtle aromas. So HTST preserves flavor well, while UHT tends to cause more noticeable flavor changes because of the greater heat exposure.
