Sterilized milk
Sterilized milk is a type of dairy product that has undergone a process of sterilization to kill microorganisms that can cause foodborne illness. This process extends the shelf life of the milk and ensures its safety for consumption.
History[edit | edit source]
The process of sterilizing milk was first developed in the 19th century by Louis Pasteur, a French chemist and microbiologist. This process, known as pasteurization, involves heating the milk to a specific temperature for a set period of time. However, sterilized milk goes through a more intense heat treatment than pasteurized milk, which kills all microorganisms, including spores.
Production[edit | edit source]
The production of sterilized milk involves several steps. First, the milk is preheated and then heated to a temperature of at least 135 degrees Celsius for a minimum of two seconds. This process, known as UHT treatment, kills all microorganisms and spores in the milk. After heating, the milk is rapidly cooled and then packaged in a sterile container to prevent recontamination.
Consumption and Use[edit | edit source]
Sterilized milk can be used in the same way as regular milk, including for drinking, cooking, and baking. It is particularly popular in countries with warm climates, where refrigeration is less common. Because it is shelf-stable, sterilized milk is also often used in food aid programs.
Health and Nutrition[edit | edit source]
Sterilized milk has the same nutritional value as regular milk, providing a good source of protein, calcium, and vitamin D. However, some people find that sterilized milk has a slightly different taste due to the high heat treatment.
