Did you know that honey never spoils? Archaeologists have found pots of honey in ancient Egyptian tombs that are over 3,000 years old and still perfectly good to eat. Honey's long shelf life is due to its unique chemical composition. It's low in moisture and highly acidic, making it an unsuitable environment for bacteria and microorganisms to grow. Plus, when bees make honey, they add an enzyme that makes hydrogen peroxide, which acts as an additional preservative.
