Many chemical and microbiological changes occur in the heating step immediately before and in the cooling step immediately after the sterilisation step and hence these sections of the plant should be taken into account in addition to the sterilisation holding tube when considering the extent of these changes. This is carried out at 60-70°C, either before or after the sterilisation step. In the final cooling step in direct systems, and in both cooling steps in indirect systems, the heat from the hot milk is transferred to the cold milk in the preheating/heat regeneration steps.

Geobacillus stearothermophilus is an extremely heat-resistant sporeformer found in milk but because it only grows at temperatures above about 50°C, it does not cause problems in UHT milk unless the milk is severely temperature abused during storage. Surprisingly, the UHT process has only a minimal effect on the nutrient value of milk. While UHT milk stands for Ultra High-Temperature Pasteurization (also referred to as Ultra Pasteurization or UP) and means that milk is heated to about 280 ºF (135 ºC) for 1-2 seconds, which kills more bacteria (both good and bad) than traditional pasteurization therefore giving the milk a much longer shelf life before it spoils. UHT milk is obtained through the process of combining whole milk with water, skimmed milk and powder-skimmed milk. At high temperatures, above about 110°C, calcium phosphate also precipitates on the walls, adding to the ‘fouling’ caused by the whey proteins2.

The main targets are Bacillus species, particularly heat-resistant ones such as B. licheniformis and B. subtilus. HTST pasteurization heats the milk to 161 degrees Fahrenheit for 15 seconds and then rapidly cools it to 39 degrees. This clearly puts a high demand on the plant operators to ensure the homogeniser is aseptic and for this reason, where possible, homogenisation is carried out before sterilisation. If you are more of a person drawn to the original taste of milk, mind you’d not want to switch to UHT treated milk.

According to a study from Lee Dexter, A microbiologist based in Texas, the extreme heating method of milk also destroys the fragile human-friendly enzymes and proteins. This profile can vary considerably as illustrated in Figures 1 and Figure 2, which show profiles of two commercial UHT installations, an indirect and a direct system, respectively.
