Question

differences between sterilisation and pasteurization

Answer 1

Sterilization of milk is aimed at killing all microorganisms present, including bacterial spores, so that the packaged product can be stored for a long period at ambient temperature, without spoilage by microorganisms.

Pasteurization – the heat treatment. Along with correct cooling, the heat treatment is one of the most important processes in the treatment of milk.The pasteurization temperature for homogenized, HTST pasteurized milk is usually 72 – 75 °C for 15 – 20 seconds.

Answer 2

Pasteurization is the process of heating food, specifically liquids, to a specific temperature to slow microbial growth in the food.Sterilization refers to the process ofeliminating all forms of bacteria from any product. ... This process kills the heat susceptible organisms and their spores.
