UHT processing has minimal impact on the major nutritional components of milk, such as protein and minerals. Due to the extremely short holding time (1-10 seconds), loss of heat-sensitive vitamins is also reduced compared to traditional sterilization methods.

UHT is better for producing shelf-stable products for ambient storage, while HTST (High-Temperature Short-Time) is better for creating refrigerated, shorter-shelf-life products with minimal flavor change

The shelf life for UHT processed milk products typically ranges from six to nine months, provided the product remains sealed in its aseptic packaging.

Direct Heating uses steam injection to heat the milk instantly (better flavor, higher cost); Indirect Heating uses heat exchangers (more energy efficient, suitable for most commodity dairy products)

The standard operating temperature range for a UHT dairy system is typically 135°C to 150°C with a holding time of just 1 to 10 seconds adjustable
