Archaeologists excavating 3,000-year-old Egyptian royal tombs have recovered clay pots of honey that remain completely unspoiled and edible. Honey’s indefinite preservation stems from three biological mechanisms: an exceptionally low moisture content (around 17β18%), high acidity (pH 3.2 to 4.5 due to gluconic acid), and natural hydrogen peroxide generated by the enzyme glucose oxidase, which bees secrete into the nectar. This creates an inhospitable hypertonic environment where bacteria and microorganisms cannot survive.
