If one day humanity faces a global crisis, what foods can surviving people eat and how long can they last?
Having stocks of certain food, you can manage to survive even during the most hungry time.
All existing products have a specific expiration date. In order to be able to extend it, people learned how to dry, salt and cool food, thereby preventing the further growth of microorganisms on its surface. According to experts, drying is the most effective method of storing food, followed by salting, and only then storage in airtight containers, which are still not able to protect products from the natural decomposition process for a long time, says bbc.com.
It is almost impossible to completely remove pathogens from food without any harm to it, which is why existing conservation methods focus more on limiting the growth of microbes. Thus, drying products can be effective because in environments with a low water content, the growth of microorganisms, which are in dire need of water for reproduction, is sharply suppressed.
Salting meat and vegetables can be effective for the same reason, as salt can remove moisture, creating an environment in which microbes cannot survive. Sugaring acts in a similar way, capable of preserving fruits and berries for many years, almost completely depriving microorganisms of the ability to reproduce. It is known that a variety of toffee, boiled sweets (which usually contain 80% sugar in the form of sucrose and glucose) and other hard sweets show a slight growth of microorganisms over several years.
Long shelf life products
An unexpected (or, incidentally, quite expected) product that even a nuclear apocalypse is likely to survive can be McDonald’s products. So, when the world famous fast food chain closed its last restaurant in Iceland in 2009, the last Big Mac sold there went to the food exhibition and is still taking a direct part in it. Although the sandwich withered and turned pale, the mold on it still did not have time to appear.
The main “culprit” for the lack of mold on Mcdonald’s products is called the sodium benzoate preservative, which is able to slow down the growth of bacteria in cooked food more than all natural conservation technologies known to humans.
Sodium benzoate is an odorless white powder supplement. It is used to slow the activity of molds and thereby helps to increase the shelf life of products.
A much more useful product for consumption in times of crisis can be honey, which is almost impossible to spoil due to the presence of a large amount of sugar in it. So, samples of honey, whose age reaches 3000 years, were found in the tombs of nobles in Georgia and even the tomb of Tutankhamun in Egypt. Another very well-preserved product can be considered very fatty foods: a variety of cheeses, fats and oils. Due to the fact that fat displaces water, products based on it can help survive even the hungry years.
By the way, people who inhabited our planet in ancient times knew about the properties of fat. Scientists have already found highly fermented oils in the peat bogs of Ireland and Scotland. It is believed that ancient people buried oil and animal fat in peat in order to preserve it and hide it from thieves as a valuable resource.
Peat is a rock formed from decayed remains of marsh plants. Today it is actively used as fuel.
Thus, in order to successfully survive the unexpected apocalypse, we recommend that you always have stocks of salty, sweet and fatty foods, the presence of which will allow you to survive even in the most unfavorable times.
