Both pasteurization and sterilization are techniques of food preservation by applying hear. Their aim is the destruction of microorganisms and their spores. The difference between the two techniques lies in the time and temperature of the heating process. 


Sterilization is performed with different foods, such as meat, fish, vegetables, fruit… it consists of placing food in a container and subjecting it to temperatures above 100ºC, usually 121ºC, during a certain period of time. After this process, all microorganisms and spores are inactivated. 


Pasteurization involves heating food at temperatures below 100ºC for a bried period of time. This method is used in many products, especially in milk and its derivatives, flavored juices, beers, because the low temperatures respect and preserve the aromas and other organoleptic characteristics. These food products have a shorter shelf life, because although viable micoorganisms are drastically reduced, some remain viable.
