How did Peter Durand modify Appert's preservation principle in 1810?
Answer
By patenting the use of tinplate canisters
While Appert proved the principle worked using fragile glass bottles, the logistics of shipping glass for military use were problematic. Almost immediately following Appert's success, an Englishman named Peter Durand secured a patent in 1810 to adapt the concept. Durand replaced the glass bottles with much more durable and stackable containers made of tinplate, commonly known as canisters. This evolution was critical for large-scale provisioning, making the packaging robust enough for rough handling during transport and storage.
