Honey

• 1. Bee Biology And Production

  ›

  A foraging bee returns to the hive after visiting more than one thousand flowers to fill its honey stomach with about 40 mg of liquid. This cavity holds roughly half the weight of an unladen bee, requiring over an hour of ceaseless work to collect enough nectar when it is plentiful. The bee sucks sugar-rich fluids through its proboscis into the honey stomach, which lies just above the food stomach that digests pollen and sugars for its own nourishment. Salivary enzymes from the hypopharyngeal gland begin cleaving complex sugars like sucrose into simpler glucose and fructose once inside the honey stomach. This process slightly raises the water content and acidity of the partially digested nectar before it reaches the hive. Hive bees then regurgitate the nectar repeatedly, forming bubbles between their mandibles to speed digestion and concentration. These bubbles create a large surface area per volume, allowing bees to evaporate a portion of the nectar's water into the warm air of the hive. The process continues until the honey reaches a final water content of between 15.5% and 18%. This concentration creates a supercooled solution where sugar levels are far beyond the saturation point of water, halting all fermentation. Bees then cap the cells of finished honey with wax to seal them from contamination and prevent further evaporation. The next section explores how humans have intervened in this natural process to harvest the substance.

  Honey hunters in Africa follow the greater honeyguide bird to locate wild beehives, a behavior that may have evolved with early hominids. A Mesolithic rock painting in a cave in Valencia, Spain, dating back at least 8,000 years, depicts two honey foragers collecting honey and honeycomb from a wild bees' nest using ladders or ropes. The first written records of beekeeping appear in ancient Egypt, where honey was used to sweeten cakes and as a base for unguents in hieroglyphs. In 594 BCE, beekeeping around Athens was so widespread that Solon passed a law requiring hives to be placed 300 ft away from those already installed by another. Modern beekeepers typically pacify bees using a smoker to trigger a feeding instinct and obscure pheromones used for communication. Before the invention of removable frames, colonies were often sacrificed to conduct the harvest, with the harvester taking all available honey and replacing the entire colony the next spring. Today, commercial operations use honey supers, empty boxes placed on top of an existing colony, to entice bees to develop more honeycomb instead of swarming. On average, a hive produces about 65 lb of honey per year, though wild bee nests are sometimes located by following specific bird species. The next section examines the chemical properties that allow this substance to last indefinitely.

• 3. Chemical Properties And Preservation

  ›

  Samples of honey discovered in archaeological contexts have proven edible even after millennia, provided its water concentration does not rise much above 18%. The key to preservation is limiting access to humidity, as honey's hydrophilic properties pull moisture into the substance if exposed to moist air. Honey contains an enzyme found in the stomach of bees called glucose oxidase, which creates gluconic acid and hydrogen peroxide to suppress bacterial growth. If the water content rises much above 25%, fermentation can begin, usually occurring after crystallization when the liquid portion consists primarily of fructose and water. Honey that is to be stored at room temperature for long periods is often pasteurized by heating it above 70 C to kill any yeast. The density of honey typically ranges between 1.38 and 1.45 kg/L at 20 C, and its viscosity increases very slowly with moderate cooling. At -20 C, honey may appear or even feel solid, but it continues to flow at very low rates. The substance has a glass transition between -42 and -51 C, below which it enters a glassy state and becomes an amorphous solid. The next section reviews worldwide production statistics and the methods used to detect fraudulent sugar additions.

• 4. Global Production And Adulteration

  ›

  In 2023, world production of honey reached 1.9 million tonnes, led by China with 24% of the total, followed by Turkey, Ethiopia, and Iran as secondary producers. Honey is sometimes adulterated by the addition of other sugars, syrups, or compounds to alter flavor, reduce costs, or increase fructose content. Clear, nearly flavorless corn syrup has become the most common adulterant in recent times, making it difficult to distinguish from unadulterated honey. One technique used to detect adulteration is Isotope ratio mass spectrometry, which can identify the addition of cane sugar or corn syrup by analyzing carbon isotopic signatures. Using this method, adulteration levels as low as seven per cent can be detected. The National Honey Board notes that no single universal method is currently capable of detecting all forms of honey adulteration with adequate sensitivity. Historical sources describe honey being blended with plant syrups such as maple, birch, or sorghum syrup and sold as pure honey. In the United States, the National Honey Board identifies honey authenticity as a major challenge for the industry. The next section investigates the scientific evidence supporting honey's use as an antibiotic and wound treatment.

  ›

  Honey's antibacterial effects were first demonstrated by the Dutch scientist Bernardus Adrianus van Ketel in 1892. Preliminary evidence suggests that it aids in the healing of partial thickness burns 4-5 days faster than other dressings, and moderate evidence suggests that post-operative infections treated with honey heal faster and with fewer adverse events than with antiseptic and gauze. Several medical-grade honey products have been approved by the US Food and Drug Administration for use in treating minor wounds and burns. For treating children, a Cochrane review concluded with moderate to low evidence that honey helps more than no treatment, diphenhydramine, and placebo at giving relief from coughing. The UK Medicines and Healthcare products Regulatory Agency suggests a homemade remedy containing honey and lemon is likely to be just as useful and safer to take for children over one year old. Infantile botulism shows geographical variation, with the US reporting 1.9 per 100,000 live births, 47.2% of which are in California. The World Health Organization recommends honey as a treatment for coughs and sore throats, stating that no reason exists to believe it is less effective than a commercial remedy. The final section traces the ancient origins of honey collection and its symbolic role in major world religions.

• 6. Historical And Cultural Significance

  ›

  Archaeologists found honey remains on the inner surface of clay vessels unearthed in an ancient tomb in Georgia, dating back between 4,700 and 5,500 years. In ancient Greece, honey was produced from the Archaic to the Hellenistic periods, and in 594 BCE, Solon passed a law about hive placement. An apiary dating from the 10th century BC was found in Tel Rehov, Israel, that contained 100 hives, estimated to produce half a ton of honey annually. In the Hebrew Bible, the Promised Land is described 16 times as
