7 foods that help people survive the end of the world

Some foods such as honey, dried beans, dark chocolate, can still be eaten and fresh after a long time.

Honey

Archaeologists found honey dating to 3,000 years old but still edible when excavating tombs in Egypt in 2015, according to Science Alert.Honey lasts so long because it has low water and high sugar levels so bacteria cannot grow.Honey also contains a small amount of hydrogen peroxide (H2O2), inhibiting microbial growth.(Photo: Good Ground).

Dried beans

Like honey, beans when dried will have low water and high sugar levels.Therefore, bacteria and mold cannot grow easily.If we store beans in closed containers, they will last for many years and still contain a large amount of protein.(Photo: Wikimedia).

Soy

Soy sauce has a shelf life of at least 3 years due to a combination of high salt content and natural fermentation.Maximum storage time depends on the type of soy sauce and storage temperature.If soy sauce smells bad, it is likely that mold grows around the lid.(Photo: Epicurious).

Vinegar

Some people may argue that vinegar is actually a broken wine or cider.However, the acidity of the vinegar is produced by using Acetobacter to ferment.Other types of bacteria cannot grow in acidic environments, so the shelf life of vinegar is very long.(Photo: Wikimedia).

Rice

30-year white rice in the tin can still be eaten, the key is in the atmosphere and temperature. Studies show that low storage temperature (about 3 degrees Celsius) and oxygen-deficient environment are very important factors for "life expectancy" of rice.Brown rice has a shorter shelf life, because the fiber bran contains unsaturated fat causing rancidity.If you find brown rice with oils and smells like old paint, it's best to remove it.(Photo: Recafo).

Dark chocolate

Adding milk to chocolate can reduce the life of this dish.If not at a fixed temperature, the fat in the chocolate will float to the surface to form a mold-like membrane.But if kept at constant temperature, chocolate can last for 2 years or longer without losing nutrients.(Photo: Fitday).

Sugar and salt

If salt and sugar are stored in a moisture-proof container, you can use them indefinitely.But if salt has added additives, such as iodine, the salt's shelf life will be reduced to about 5 years.(Photo: Wikimedia).
