Why Honey does not spoil
Honey is the "magical food" that never spoils!
Honey pots that are over 3000 years old have been found in ancient Egyptian tombs. The consistency and taste are the same as day old honey. The chemistry that makes this possible is astonishing and is directly connected to the health benefits of honey
Most food items will rot away. It is a law of nature - this is due to bacteria and mostly because of moisture that serves as an accelerator to the process. We have come to terms with this process and humans had to find workarounds to preserve different food items. Honey is the exception due to the way it is processed by honey bees.
Honey has been called the only food that truly lasts forever, thanks to its magical chemistry and the handiwork of bees. The nectar from flowers mixes with enzymes inside the bees that extract it, which changes the nectar’s composition and breaks it down into simple sugars that are deposited into honeycombs. Fanning action from the bees’ wings and the enzymes from their stomachs create a liquid that is both highly acidic [PDF] and low in moisture—truly inhospitable digs for bacterial growth.
The processing and sealing of honey also adds to its indefinite shelf life. Despite being low in moisture, honey’s sugars are hygroscopic, which means that they take in moisture from the air. When the heated and strained honey is sealed properly, moisture cannot be absorbed, and the honey stays the same forever. The oldest jar of the sweet stuff ever found is believed to be 5500 years old.
