Why Honey Never Expires

Why honey never expires even when it's three thousand years old. Archaeologists have pulled sealed jars of honey out of Egyptian tombs that have been buried for more than 3,000 years, opened them up, tasted what was inside, and found the honey perfectly edible. No mold. No bacteria. No decay. The same thing has happened with honey recovered from ancient Georgia and from Roman ruins. Every other food on the planet has a clock running on it bread goes stale in days, meat rots in hours, even canned vegetables eventually fail but a sealed jar of honey will outlive you, your children, and probably your great-grandchildren. So why does honey never spoil? There are three reasons, and they all start inside the bee. The first is water. Honey is only about 17% water, while most foods are 50-70% or even 90% water. Bacteria, mold, and yeast need water to survive, and any microbe that lands in honey gets the water sucked straight out of its body through osmosis. The cells shrivel and die. Biologically speaking, honey is a desert. The second reason is acidity honey sits at roughly the same pH as black coffee, which shuts down most bacteria before they can multiply. The third reason is the bees themselves: when a worker bee mixes nectar with her saliva, the enzyme glucose oxidase slowly produces tiny amounts of hydrogen peroxide. That is the same chemical you put on a cut. Raw honey, straight out of the comb, carries its own built-in antiseptic. Put those three together almost no water, high acidity, and a slow drip of hydrogen peroxide and you have a food that no microbe on Earth can survive in. That is why the honey jar in your pantry has no expiration date. The crystallization people throw their honey out for is not spoilage at all it is just sugar settling out of the liquid, and a few seconds in warm water dissolves it right back. The honey humans ate four thousand years ago is, chemically, the same honey you spoon onto toast tomorrow morning.
