UHT kills all pathogenic and souring bacteria along with their spores, which helps ensure the milk remains safe for consumption over extended periods.

It extends the shelf life of the milk, allowing it to be stored for several months without refrigeration, although some nutrients such as thiamine and Vitamin C may be reduced.
