Beeswax has applications in human food and flavoring, for example as a glazing agent. It is edible, in the sense of having similar negligible toxicity to plant waxes, and is approved for food use in the European Union. However, the wax monoesters in beeswax are poorly hydrolysed in the guts of humans and other mammals, so have insignificant nutritional value. Some birds, such as honeyguides, can digest beeswax.
