Which scientist's later research confirmed the microbiological basis for why Appert’s heating process worked?
Answer
Louis Pasteur
Although Appert’s process was empirically sound—the heat effectively stabilized the food—the reason *why* the sealed, heated food did not spoil remained a mystery for decades because microorganisms were not understood. The scientific validation of Appert’s work came much later in the latter half of the 19th century, driven by the research of Louis Pasteur. Pasteur’s investigations into fermentation and spoilage conclusively proved that microscopic living organisms caused food degradation, thereby scientifically confirming that Appert’s method of applying sufficient heat to sealed containers successfully eliminated these invisible threats.
