This is a food processing technology, which is mainly used for sterilization of liquid food (such as milk, juice, soybean milk, etc.). During this process, the food is rapidly heated to a high temperature of 135-150 ° C, held for 2-3 seconds, and then rapidly cooled. Such high temperatures can effectively kill bacteria, molds, and yeast, including their spores, thus meeting the requirements of commercial sterility.
Food treated with UHT can be stored for a long time at room temperature, usually with a shelf life of several months, without the need for refrigeration, greatly extending the shelf life of food and facilitating transportation and storage. UHT technology is widely used in the production of ready to drink beverages, dairy products, and other liquid foods that require long-term preservation. |
