- Honey has an eternal shelf life, with examples of edible honey found in ancient Egyptian tombs.
- Honey's longevity is due to its low moisture content, which makes it inhospitable to bacteria and microorganisms.
- Honey's natural acidity (pH 3–4.5) also kills off most organisms that could spoil it.
- Bees process nectar to remove moisture and add enzymes that produce gluconic acid and hydrogen peroxide, further inhibiting spoilage.
- Honey has been used for centuries in medicinal remedies, such as wound care, due to its antibacterial properties and hydrogen peroxide content.
- To prevent spoilage, honey should be kept sealed to avoid adding moisture, as exposure to water can cause it to go bad.
