A single ripening banana can spoil an entire ship's rations
Food
A single piece of fruit can trigger a chemical chain reaction that turns a ship's entire fresh food supply into a wall of mold.
Inside the cramped cargo holds of a naval vessel, a lone overripe banana acts like a biological saboteur by releasing ethylene gas. This odorless plant hormone signals nearby produce to ripen instantly, which in turn releases more gas. In the tight confines of a ship, this feedback loop can accelerate spoilage by three hundred percent. To fight this, naval galleys use citric acid to keep food acidity below a 4.6 pH level, a invisible chemical barrier that prevents the growth of deadly bacteria like botulism.
