Explanation: Pasteurization for pasteurisation) is a process of heating a food, which is usually a liquid, to a specific temperature for a predefined length of time and then immediately cooling it after it is removed from the heat. This process slows spoilage due to microbial growth in thefood. Unlike sterilization, pasteurization is not intended to kill all micro-organisms in the food.
