Keeping Eggs Fresh Without a Refrigerator: Ancient Tips
In the past, refrigeration was not available to many households, yet eggs were still kept fresh and edible for weeks or even months. How did people manage to keep eggs fresh without modern technology? The answer lies in ancient techniques that relied on natural methods and the properties of eggs themselves. Here’s a look at some of the best time-tested tips to keep eggs fresh without using a refrigerator.
1. Water Glass Method
The water glass method, also known as the “limewater method,” was one of the most common ways to preserve eggs in the past. To use this method, mix a solution of water and sodium silicate (a.k.a. water glass). The eggs are then submerged in the solution, which forms a protective coating around the shell, preventing air from entering. As a result, eggs can stay fresh for up to 6 months or more.
2. Salt or Lime Preservation
In ancient times, people used salt or lime to preserve eggs. The eggs would be stored in a container and then covered with a thick layer of either salt or slaked lime. Both of these substances create an airtight seal that prevents bacteria from getting inside the egg. The preserved eggs are stored in a cool, dry place and can last for several months.
