Refrigeration is a reasonably new phenomenon, so for millennia, individuals needed to discover intelligent methods to protect meals. These practices slowed the expansion of microorganisms that would trigger foodborne sicknesses or lead meals to rot. Many preservation practices aside from refrigeration — like salting, drying, smoking, pickling and fermenting — have been used for a very long time.
These strategies apart, how did historical individuals retailer their leftovers?
It seems that early hunter-gatherers had some fairly inventive methods to increase the “shelf life” of their larder.

Fishing for mammoth
One fall morning in 2015, two farmers in Michigan made an sudden discovery: a pelvis bone from a mammoth. After a number of telephone calls and an excavation, a analysis workforce uncovered extra paleontological and archaeological proof that introduced the scene into higher readability.
Greater than 11,000 years in the past, mammoth herds roamed North America. For hunter-gatherers, bringing down an animal the dimensions of an African elephant can be like profitable the lottery — a prize you do not wish to lose. So, some Indigenous individuals put their mammoth leftovers into ponds to maintain it for later use.
“The pond affords a spot to stash carcass elements,” Daniel Fisher, a professor and curator within the College of Michigan Museum of Paleontology, advised Stay Science. “What’s the various when there are different predators and scavengers on the panorama who will gladly partake of a meal?”
The carcass was purposely positioned in one of many many small, shallow ponds that dot the postglacial panorama of the Higher Midwest. However the meat’s preservation wasn’t as a result of water, precisely; it was largely the exhausting work of the bacteria, Lactobacilli, that dwell within the water.
Lactobacilli produce lactic acid, a chemical byproduct of anaerobic respiration. The micro organism colonize the meat, and the lactic acid preserves the muscle mass. Fisher additionally credited the low temperature and the low oxygen content material of the lake water in aiding the preservation course of.
Fisher believes the hunt most likely occurred within the autumn. Felled animals have been butchered the place they died, and huge items have been deposited within the water in close by small ponds. The meat remained edible till the next summer season. Fisher is aware of this as a result of he has performed experiments utilizing deer, lamb and even horse. He discovered that the meat was nonetheless edible (after cooking it first to kill any dangerous micro organism that may have taken up residence within the meat), even after spending months submerged in comparable small, chilly ponds.
“The lactic acid additionally tenderizes the meat,” Fisher stated. “It does impart a robust odor and style, like Limburger cheese. It makes an fascinating meal.”
Go the lavatory butter and jam
Protecting meals cool is smart, however not everybody had a lake of their yard. Burying meals is one other ingenious solution to hold meals contemporary. Burial shields meals from daylight, warmth and oxygen, all of which improve the speed at which meals spoils.
Bogs supply an intriguing burial possibility. A lavatory is a freshwater wetland of soppy, spongy floor consisting primarily of partially decayed plant matter, referred to as peat. The cool, low-oxygen, extremely acidic setting is ideal for preserving perishable meals.

In Northern Europe, historical civilizations would put meals, together with butter, into the lavatory to protect it. Archaeologists have pulled wads of a waxy, paraffin-like substance from the waterlogged muck. Researchers carried out chemical analyses on the waxy substance and recognized it as a dairy product, giving it the enjoyable alliterative identify “lavatory butter.”
“Inside two or three years, the fats within the contemporary butter degrades into constituent elements,” stated Jessica Smyth, an assistant professor within the College Faculty Dublin Faculty of Archaeology who revealed a 2019 research on lavatory butter within the journal Nature. “You have got a lump of fatty acids.”
Bogs provided early agricultural communities a solution to protect perishable meals, like dairy merchandise, for an extended interval. Based on Smyth, there are ethnographic mentions of individuals burying their summer season butter in bogs for storage. The curated butter is edible, however it might tackle the tangy flavors of the encompassing peat that’s an acquired style.
“It’s straightforward to take a look at lavatory butter as an anomaly or freak occasion, nevertheless it was most likely a standard follow,” Smyth advised Stay Science. “The peatlands are offering a window into prehistoric agricultural practices which have vanished from the world.”
