UHT (Ultra-High-Temperature) milk, also known as long-life milk, is a type of dairy product that undergoes ultra-pasteurization at temperature above 135°C for few seconds, which allows its storage at room temperature for up to six months. There are several synonyms for UHT milk, such as shelf-stable milk, long-shelf milk, ultra-pasteurized milk, sterilized milk, or ambient milk. It has become increasingly popular among consumers due to its long shelf life and convenience, making it a favorite choice in areas where refrigeration is not possible. Despite some negative opinions regarding its taste, UHT milk remains a valuable alternative for people on-the-go or those living in areas with limited access to fresh dairy products.
