Earlier than the arrival of fridges, folks needed to discover intelligent methods to protect meals. Practices will sluggish the expansion of microorganisms that may trigger illness in meals or trigger meals to rot. Many preservation strategies apart from refrigeration comparable to salting, drying, smoking, pickling, fermentation are used over an extended time period.
Ignoring the above strategies, how did historic folks retailer leftovers? Because it seems, hunter-gatherers had some very inventive methods to increase the shelf lifetime of meals.
On a fall morning in 2015, two farmers in Michigan found the pelvis of a mammoth. After a number of telephone calls and an excavation, the group found further paleontological and archaeological proof that clarified many questions.
Greater than 11,000 years in the past, herds of mammoths roamed North America. For hunter-gatherers, catching a mammoth was like profitable the lottery. So, some natives put extra mammoth meat within the pond to eat regularly.
Professor Daniel Fisher, curator of the Museum of Paleontology on the College of Michigan, informed Stay Science: “The pond is sort of a place to retailer the meat of an animal. What are the options when predators and animals are stored? different scavengers able to eat?”.
Extra mammoth meat was dumped within the many small, shallow ponds that dot the post-glacial interval within the Higher Midwest. Nevertheless it’s not the pond water that preserves the meat, however the Lactobacilli micro organism that dwell in it.
Lactobacilli produce lactic acid, a chemical byproduct of anaerobic respiration. The micro organism get into the meat and the lactic acid preserves the muscle. Mr. Fisher additionally mentioned that the low temperature and low oxygen content material of the lake water helped the preservation course of.
Fisher believes the hunt might occur within the fall. The meat of the animals is launched into small ponds close by and might be eaten till the next summer season. He carried out experiments utilizing deer, elk, sheep and even horses and located that the meat was nonetheless edible after months of soaking in an identical small pond on the time.
“The lactic acid additionally tenderizes the meat. It has a robust scent and style, like Limburger cheese. It makes for a pleasant meal,” he says.
Holding meals cool is a option to protect them longer, however not everybody has a pond or lake close to their residence. Burying meals to forestall them from being uncovered to daylight, warmth, and oxygen is one option to decelerate decomposition.
The ancients might bury leftovers in wetlands with delicate, porous soil. This cool, low-oxygen, extremely acidic surroundings is ideal for storing perishable meals.
In Northern Europe, historic civilizations would bury meals in quagmire for preservation. Even butter and jam previously have been preserved on this manner.
