Sweet, viscous liquid food, golden in colour, produced in the honey sacs of various bees from the nectar of flowers.
Honey has played an important role in human nutrition since ancient times; until about 250 years ago, it was almost the sole sweetening agent. Honey is often produced on a commercial scale from clover ( Trifolium ) or sweet clover ( Melilotus ) by the domestic honeybee . The nectar is ripened into honey by inversion of most of its sucrose into the sugars levulose ( fructose ) and dextrose ( glucose ) and the removal of excess moisture. Honey is stored in the beehive or nest in a honeycomb, a double layer of uniform hexagonal cells constructed of beeswax and propolis (a plant resin). The honey is used in winter as food for the bee larvae and other members of the colony. Honey extracted for human consumption is usually heated to destroy fermentation-causing yeasts and then strained. See also beekeeping .
