What are the disadvantages of UHT milk?
Drawbacks of UHT milk: 1. milk quality problems/flavor changes – complaints include “heated” flavor, stale/oxidized flavor, bitter taste due to peptides produced by heat-resistant proteases, or bad odor/acidity/sour taste. to residual bacterial enzyme activity.

There is a very noticeable difference in taste between pasteurized and UHT milk, and anecdotal evidence from discussions with several friends over the years is that those who are used to pasteurization think UHT tastes bad, while those who are used to UHT do not notice the difference. Or they do notice, but it doesn’t matter either way.
Why does long life milk last so long?
The process that extends the shelf life of milk is called ultra-high temperature (UHT) processing or treatment, in which milk is heated to 280 degrees Fahrenheit (138 degrees Celsius) for two to four seconds to kill all bacteria in the milk. Compare that to pasteurization, the standard preservation process.

What are 3 advantages of purchasing UHT milk?
Advantages of UHT milk
- Extended shelf life. UHT or ultra pasteurized milk is known to last much longer than regular milk.
- Reduced processing time. Pasteurization reduces the number of microorganisms and enzymes in UHT milk to almost zero.

Can I use UHT milk to make cheese?
Ultra-pasteurized (UP) or ultra-high temperature (UHT) milk is milk that has been heated above 275°F for approximately one second. Ultra-pasteurized milk does not perform well in cheese production because the proteins are unstable. As a result, the calcium in the milk does not bind properly to make a good curd.
