What was the essential distinction Appert understood about his preservation technique empirically?

Answer

Heat treatment combined with an airtight seal worked

Nicolas Appert succeeded in developing a practical method for long-term food storage through rigorous, empirical observation, even though he lacked the scientific vocabulary to explain the biological mechanism behind it. He systematically observed that by enclosing food securely in containers and subsequently subjecting those containers to high temperatures, typically boiling water for a set duration, the food remained unspoiled for extended periods. He understood the combination of an airtight seal (preventing recontamination) and sufficient heat treatment (rendering the contents safe) was the operational formula. However, the underlying reason—that the heat killed specific heat-sensitive microbes—was not confirmed until Pasteur's later work, leaving Appert with the correct practical steps but an incomplete theoretical understanding.
