Question

A student is curious to learn about the major developments in food processing and technology that occurred before the 20th century. In this context, name two researchers who made a significant contribution in those times. Also name the process developed by each one of them.

Hint:

Nicolas Appert = Canning; Louis Pasteur = Pasteurization. Both methods help preserve food and increase shelf life.

Answer 1

Significant advancements in food processing prior to the 20th century were achieved by the subsequent researchers:
Nicolas Appert (1749–1841): Introduced canning (appertisation), a method of food preservation involving sealing food in airtight containers and heating to eliminate microbes.
Louis Pasteur (1822–1895): Developed pasteurization, a process of heating liquids such as milk and wine to specific temperatures to eradicate harmful bacteria while maintaining taste and quality.
