What is Uht Milk?

  • Heat treatment is the process done to make the milk last longer. By heat-treating milk, UHT milk (durable milk, long-life milk) and pasteurized milk (daily milk) are created.
  • The UHT technique, which is very expensive, is applied at high temperature with emphasis on sterility. UHT technique (Ultra High Temperature) is applied by keeping the milk at very high temperatures.
  • In UHT milk application, the milk is brought to a value between 135-150˚ degrees for a few seconds. This makes it more durable.
  • The purpose of exposing milk to such high temperatures is to destroy the ingredients that cause milk to spoil and cause disease.
  • Aseptic packaging is as important as temperature application in UHT milk.
  • Aseptic packaging is the packaging made in a way that prevents the entry of oxygen, moisture or microorganisms into the product from the outside and leakage that may occur from the inside to the outside.
  • UHT milk lasts for a long time and does not need a cold chain after it is produced. For this reason, it is kept at room temperature in the markets.
  • In short, UHT milk is a product that does not contain any additives, only heat treatment and a special packaging technique are applied in order to be durable.

How Long Is Uht Milk Shelf Life?

The life of UHT milk is between 2 and 6 months if the outer packaging is of good quality and is not damaged. The life of UHT milk after opening the package is 2 days.

The shelf life of milk varies according to its fat content and the processes it has undergone. So, how do you know if the milk is spoiled?

  • If your milk has a strong odor and tastes sour or bitter, your milk is spoiled.
  • Even if the consistency of the milk is disturbed and clumping has occurred, your milk is most likely spoiled.
  • If there is yellowing or darkening in color, the milk is definitely spoiled.
  • If you are not sure if the milk is spoiled, you can use the boiling test.
  • Put some milk in a pot and start boiling. If you see a change in the consistency of the milk after it starts to boil, if the milk – oil – water separates from each other and creates a different consistency, it means that the milk is spoiled.
  • If you have any doubts about the deterioration of the milk, avoid using the product.

  • Since it is not known exactly what is in the milk sold in the open and at what stages it passes, it is said that UHT milk produced under completely hygienic conditions is better for health.
