There is a stereotype, that milk, packaged in tetra or fine pak, which has a long shelf life contains additions or preservatives. Sterilization of UHT milk – is carried out according to a method, which combines rapid heating up to 140°C followed by cooling to 25 °C. The technology of production of UHT milk in aseptic carton packaging does not imply the use of preservatives. Ultra-pasteurization is the most gentle processing, which allows the preservation of the organoleptic characteristics, composition and nutritive value of milk. When the product is boiled not only bacteria, but also vitamins are destroyed. In the process of pasteurization, the vitamins are preserved, and the bacteria are destroyed, (but spores remain). Therefore, pasteurized milk has a small shelf life: in its composition all the potential bacteria are destroyed. During ultra pasteurization bacteria and spores are destroyed, but vitamins are preserved, in other words the milk remains "alive". The taste of milk is even "fresher", because the processing and cooling time is reduced. Thus, milk can be kept in a closed package up to five months, even at the room temperature (not in refrigerator) without the need for a heat treatment. In 100 g of milk are:
