Which process did Pasteur develop to kill pathogens in beverages?

• A. Sterilization
• B. Filtration
• C. Desiccation
• D. Pasteurization

Answer: (D)

Pasteurization is the heat treatment designed by Louis Pasteur to kill pathogens in beverages while preserving quality. By heating liquids to a modest temperature for a short time, Pasteur showed that disease-causing microbes could be destroyed without boiling the drink away, reducing spoilage and illness risks. This method targets harmful organisms but isn’t intended to achieve complete sterility, which would require much harsher conditions and often spoil the flavor. Filtration removes microbes physically rather than killing them with heat, and desiccation removes water to inhibit growth, neither of which matches the goal of safe, tasty beverages via controlled heat.
