Germ theory's stance that the "germ" was the disease's necessary and sufficient cause—the single factor both required and complete to result in the disease—proved false. [12] Germ theory gradually evolved to include other factors, whereupon germ theory resembled miasmatic theory , which had had to recognize bacteria as a causal factor, and ...
A major breakthrough came in 1954, when Rossi invented and patented a pasteurization process to aseptically pack pure chilled juice in glass bottles, allowing it to be shipped and stored without refrigeration. He provided consumers the fresh taste of orange juice made from 100-percent fruit.
The Pasteurization of France is split into two sections: the first section ("War and Peace") is a history of the development and adoption of Pasteur's germ theory while the second ("Irreductions") is a theoretical work, structured into numbered clauses and elaborations, which presents an early version of actor-network theory.
