Salt preserved food through osmosis and bacterial inhibition.
The Salting Process:
Meat was rubbed thoroughly with salt—the crystals adhering to all surfaces, penetrating into crevices. The salt drew moisture from the meat (osmotic pressure pulling water molecules through cell walls), creating environment hostile to bacteria.
The salted meat was then stored—packed in barrels with additional salt layers, hung in cool, dry areas, or buried in salt-filled containers. The salt continued drawing moisture, gradually desiccating the meat, preventing bacterial growth.
The Salt Requirements:
Preserving meat required substantial salt—perhaps 10-15 pounds of salt per 100 pounds of meat. A household planning to preserve several hundred pounds of meat (typical for families with livestock) needed many tens of pounds of salt—a significant expense and storage challenge.
The Timing:
Meat was salted immediately after slaughter (waiting allowed bacterial growth to begin, reducing preservation effectiveness). During autumn slaughter season, salt consumption spiked dramatically as communities worked to preserve winter supplies.
