The Science Behind Honey's Eternal Shelf Life
Geege Schuman stashed this in Science Too
Bees are magical:
A jar of honey’s seal, it turns out, is the final factor that’s key to honey’s long shelf life, as exemplified by the storied millennia-old Egyptian specimens. While honey is certainly a super-food, it isn’t supernatural–if you leave it out, unsealed in a humid environment, it will spoil. As Harris explains, ” As long as the lid stays on it and no water is added to it, honey will not go bad. As soon as you add water to it, it may go bad. Or if you open the lid, it may get more water in it and it may go bad.”
So if you’re interested in keeping honey for hundreds of years, do what the bees do and keep it sealed–a hard thing to do with this delicious treat!
