What are the differences sterilisation + pasteurisation?
Answers:
Sterilization kills all living organisms. Pasteurisation kills only pathogenic bacteria and leaves some other bacteria alive and capable of multiplying.
Pasteurization is usually better for preserving the flavor and the nutritional value of the food, while making it harmless for consumption.
Sterilization is better for extending the shelf-life of the food.
Pasteurization (or pasteurisation) is the process of heating food for the purpose of killing harmful organisms such as bacteria, viruses, protozoa, molds, and yeasts. The process was named after its inventor, French scientist Louis Pasteur. The first pasteurization test was completed by Pasteur and Claude Bernard on April 20, 1862.
Sterilization can mean:
Sterilization (surgical procedure) - an operation which renders an animal or human unable to procreate
Sterilization (microbiology) - the elimination of microbiological organisms
