That being said, you do not have to boil this type of milk. Thus simply boiled milk lasts for about 2-3 days in the fridge in an air-tight container or bottle at or below 40°F. This depends on the type of milk you are using. Measure the temperature of the milk with a thermometer just as it reaches a boil. To prevent the dairy from curdling, heat the milk gently over medium-low heat. Unless you have a temperature measurement device - a thermometer or a water pasteurization indicator (WAPI) - the bubbles generated by boiling water are the only visual indicator. Milk is a compound liquid which comprises fat in emulsion form, protein in colloidal state and lactose as true solution. This is done to improve the keeping quality, taste and flavour of the milk.

The boiling point of a liquid varies depending upon the surrounding environmental pressure. Heat it over the boiling water, stirring constantly. BOILING AND PASTEURIZATION Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. According to the Department of Physics at the University of Illinois at Urbana-Champaign , that boiling point is around 212 F (or 100 C). Pour the raw milk into the top pan. The best temperature for heating almond milk is between 140 to 150 degrees Fahrenheit (60 to 65 degrees Celsius). Milk that has been watered down contains more water and less solutes, so its freezing point is closer to 0 °C. So a thin skin forms over the milk when it reaches the boiling point. Credit: Hamza Bounaim The SCA recommends heating milk to 55-65°C (139-149°F) with a maximum temperature of 70°C (158°F) and minimum of 50°C (122°F).
