How Canned Food Is Made - And Why It Took 100 Years to Get Right

Pull a can from your shelf. Open it and listen. That hiss is the first air to touch the food inside since the day it was sealed. Weeks ago. Months. Maybe years. This is the full story — how a confectioner won Napoleon's twelve-thousand-franc prize by preserving food in glass jars without understanding why it worked. How glass gave way to tin that needed a hammer to open. How lead seals poisoned entire Arctic expeditions. And how it took almost a century of explosions, poisonings, and engineering failures before the modern double seam, retort sterilization, and vacuum seal turned a dangerous invention into the most reliable food preservation system ever created.
