Archaeologists have reportedly tasted honey recovered from ancient Egyptian tombs and found it still edible after roughly 3,000 years. Honey resists spoilage because it contains almost no water, is naturally acidic, and its enzymes produce small amounts of hydrogen peroxide, creating an environment most microbes cannot survive. The claim is circulating widely as a popular food-science fact, with many remarking that honey is one of the few foods that essentially never goes bad.
- 2Study reveals limits of hydrogen peroxide detection tool▼Research shows limits of specificity of tool used to detect hydrogen peroxide
Research from Agência FAPESP reports that a widely used tool for detecting hydrogen peroxide is less specific than assumed, meaning it may respond to other molecules and produce misleading readings. The finding matters for laboratories using this method in studies of cell signalling and oxidative stress, where accurate measurement of hydrogen peroxide is essential.
