Who developed Pasteurization?

Who developed Pasteurization?

• A. Louis Pasteur
• B. Joseph Lister
• C. Ignaz Semmelweis
• D. Robert Koch

Answer: (A)

Pasteurization is a heat treatment designed to kill harmful microbes in liquids while preserving quality, and it was developed by Louis Pasteur. In the 1860s he showed that microbes cause spoilage and disease, and that applying controlled heat could destroy those microbes without ruining the liquid. He first used this idea to prevent souring in wine, which led to the concept of pasteurization and, later, to safer milk production by reducing pathogens and extending shelf life. Other scientists mentioned made major contributions to microbiology—Lister advanced antiseptic surgery, Semmelweis promoted hand hygiene to prevent puerperal fever, and Koch helped establish germ theory—but they did not develop pasteurization.
