honey, sweet, viscid fluid produced by honeybees from the nectar of flowers. The nectar is taken from the flower by the worker bee and is carried in the honey sac back to the hive. It is transformed into honey by enzymes produced in the honey sac, which convert the natural sucrose (a complex sugar) in the nectar into fructose and glucose (simple sugars). The sugary fluid is stored in open cells, which are capped with wax when the material has reached the consistency of honey. The formation of honey is accomplished by the evaporation of the excess water in air circulated by the moving wings of workers. The honey required for an average colony to maintain itself through a year has been estimated as being between 400 and 500 lb (180–225 kg). The excess of the hive's requirement is used by humans for food. Honey is marketed either in the comb or with the comb removed by straining, by centrifugal force, or by gravity. The flavor and color of honey depend upon the kind of flower from which the nectar was taken, e.g., linden honey, lavender honey, and wild rose honey. Much of that produced in the United States is the pale, delicately flavored alfalfa and clover honey. Among the numerous other blossoms yielding nectar are those of the basswood, buckwheat, orange, palmetto, sage, and tupelo. The leading producers of honey are Argentina, Australia, Canada, and the United States. From earliest times until cane sugar became commercially important, honey was a major sweetening agent. Honey is easily absorbed and utilized by the body. It contains about 70% to 80% sugar; the rest is water, minerals and traces of protein, acids, and other substances.
BibliographySee U.S. Agricultural Research Service, Beekeeping in the United States (rev. ed. 1971). honeySweet, 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. honey any similar sweet substance, esp the nectar of flowers honey [′hən·ē] (food engineering) The sweet, viscous secretion composed principally of levulose and dextrose that is deposited in the honeycomb by the honeybee. Honey a sweet syrupy substance elaborated for food by worker bees, primarily from the nectar of flowers; a valuable human food product. According to the natural source, a distinction is made between floral honey (from nectar) and honeydew honey (from sweet secretions on the leaves and stems of plants). The floral honeys include those obtained from linden, buckwheat, clover, sun-flower, willow herb, and other plants. The chemical composition of honey depends on the species of plant from which it is derived, climatic conditions, and the method of commercial processing. Floral honey is 13-20 percent water, over 80 percent carbohydrates (principally glucose and fructose; also sucrose, maltose, and others), 0.4 percent proteins, and 0.3 percent ash. Honey contains organic acids (malic, citric, gluconic), enzymes (amylase, catalase, invertase), aromatic and mineral substances (K, Na, Ca), small amounts of vitamins (B2, PP, C, B6, H, K, and E), alkaloids, and pigments. Nectar that is freshly deposited in the cells of a honeycomb has a fluid consistency. As the water is evaporated, the nectar ripens, thickens, and becomes viscous. The enzyme invertase converts the sucrose in the nectar into glucose and fructose. After the honey ripens, the bees seal up the honeycombs with wax caps. The honey extracted from the honeycombs gradually crystallizes upon storage. First the surface crystallizes, and then the crystals gradually form toward the bottom. There are white (from willow herb), yellow (from white acacia, sainfoin, linden, sunflower), and dark brown (from buckwheat, heather) honeys. Most honeys are sweet, but some are stringent; the aroma and taste depend on the honey’s origin. The aggregate of flavor and aroma is called the bouquet of the honey. The viscosity of honey varies: acacia honey is fluid, and honeydew honey is sticky. Honeydew honey (and floral honey mixed with a considerable amount of honeydew) is harmful to bees. Commercial honey is obtained from the combs by centrifugation in an extractor and sometimes by pressing. Honey is rarely sold in the honeycomb. Sometimes different varieties of honey are mixed to normalize the thickness and to obtain the desired aroma, color, and flavor. Barrels made of linden, beech, plane, willow, cedar, and alder serve as containers for honey. Honey turns dark from oak barrels and acquires a tarry odor from barrels of coniferous varieties. Honey is stored on premises that are free of other odors. Honey is valuable as a dietary and therapeutic agent (for example, to treat emaciation). It is also used in the food industry.
