Honey is a sweet and viscous fluid produced by honey
bees (and some other species of bee), and derived from the nectar of
flowers. According to the United States National Honey Board and various international food regulations,
"honey stipulates a pure product that does not allow for the addition of any other substance...this includes, but is not limited
to, water or other sweeteners". This article refers exclusively to the honey produced by
honey bees (the genus Apis); honey produced by other bees or other insects has very
different properties.[1]
Honey is significantly sweeter than table sugar and has
attractive chemical properties for baking.[2] Honey has a distinctive flavor which leads some people to prefer it over sugar and other
sweeteners.
Most microorganisms do not grow in honey because of its low water activity of
0.6[3]. However, it is important
to note that honey frequently contains dormant endospores of the bacteria Clostridium
botulinum, which can be dangerous to infants as the endospores can transform into toxin-producing bacteria in the
infant's immature intestinal tract, leading to illness and even death[4] (See "Precautions" below).
The study of pollens and spores in raw honey (melissopalynology) can determine floral sources of honey[5]. Because bees carry an electrostatic charge, and can attract
other particles, the same techniques of melissopalynology can be used in area environmental studies of radioactive particles, dust, or particulate pollution[6][7].
A main effect of bees collecting nectar to make honey is pollination, which is crucial
for flowering plants[8].
The beekeeper encourages overproduction of honey within the hive so that the excess can be taken without endangering the bees.
When sources of foods for the bees are short the beekeeper may have to give the bees supplementary nutrition[9].
Honey formation
Honey is laid down by bees as a food source. In cold weather or when food sources are scarce, bees use their stored honey as
their source of energy[10]. By
contriving for the bee swarm to make its home in a hive, people have been able to semi-domesticate the insects. In the hive
there are three types of bee: the single queen bee, a seasonally variable number of
drone bees to fertilize new queens, and some 20,000 to 40,000 worker bees[11]. The worker bees raise
larvae and collect the nectar that will become honey in the hive. They go out, collect the sugar-rich flower nectar and return to
the hive. As they leave the flower, bees release Nasonov pheromones. These enable other bees to find their way to the site by smell[12]. Honeybees also release Nasonov pheromones at the entrance to
the hive, which enables returning bees to return to the proper hive[12]. In the hive the bees use their "honey stomachs" to ingest and regurgitate the nectar a number of times until it is partially digested[13]. It is then stored in the honeycomb.
Nectar is high in both water content and natural yeasts which, unchecked, would cause the sugars in the nectar to ferment[10]. After the final regurgitation, the
honeycomb is left unsealed. Bees inside the hive fan their wings, creating a strong draft across the honeycomb which enhances
evaporation of much of the water
from the nectar[10]. The
reduction in water content, which raises the sugar concentration, prevents fermentation. Ripe honey, as removed from the hive by the beekeeper, has a long shelf life and will not ferment[10].

Honey is a mixture of sugars and other compounds. With respect to carbohydrates, honey is mainly fructose (about 38.5%) and glucose (about 31.0%)[2]. The remaining carbohydrates include maltose, sucrose, and other complex
carbohydrates[2].
Honey contains trace amounts of several vitamins and minerals[14]. As
with all nutritive sweeteners, honey is mostly sugars and is not a significant source of vitamins or minerals[15].
Honey also contains tiny amounts of several compounds thought to function as antioxidants, including chrysin, pinobanksin, vitamin C, catalase, and
pinocembrin[16][17].
The specific composition of any batch of honey will depend largely on the mix of flowers available to the bees that produced
the honey.[15]
Honey has a density of about 1.36 kg/liter (40% denser than water)[18].
- Typical honey analysis[15]
The analysis of the sugar content of honey is used for detecting adulteration.[citation needed]
Types of honey
Blended
Most commercially available honey is blended, meaning that it is a mixture of two or more honeys differing in floral source,
color, flavor, density or geographic origin.
Polyfloral
Polyfloral honey is derived from the nectar of many types of flowers.
Monofloral
-
Different monofloral honeys have a distinctive flavor and colour due to differences between their principal nectar sources. Beekeepers keep monofloral beehives in an area where the bees have access to only one type
of flower, because of that flower's properties. In practice, because of the difficulties in containing bees, a small proportion
of any honey will be from additional nectar from other flower types.
Honeydew Honey
Instead of taking nectar, bees can take honeydew, the sweet secretions of
aphids or other plant sap-sucking insects. Bees collecting this resource have to be fed protein
supplements, as honeydew lacks the protein-rich pollen accompaniment gathered from flowers.
Germany's Black Forest is a well known source of
honeydew-based honeys. Honeydew honey is popular in some areas, but in many areas beekeepers have difficulty selling the stronger
flavored product.
Honeydew honey has a much larger proportion of indigestibles than light floral honeys, which can cause dysentery, resulting in the death of colonies in areas with cold winters. Good beekeeping
management requires the removal of honeydew prior to winter in colder areas.
Honey processing
- Comb honey Honey sold still in the original bees' wax comb. Comb honey was once
packaged by installing a wooden framework in special honey supers, but this labor intensive
method is being replaced by plastic rings or cartridges. With the new approach, a clear cover is usually fitted onto the
cartridge after removal from the hive so customers can see the product[citation needed].
- Certified Organic Honey, according to the USDA,
organic honey is quite rare to find due to the fact that most beekeepers "routinely use sulfa compounds and antibiotics to
control bee diseases, carbolic acid to remove honey from the hive and calcium cyanide to kill colonies before extracting the
honey, not to mention that conventional honeybees gather nectar from plants that have been sprayed with pesticides."
- Raw honey Honey as it exists in the beehive or as obtained by extraction, settling or straining without adding heat
above 120 degrees fahrenheit. Raw honey contains some pollen and may contain small particles of wax. Local raw honey is sought
after by allergy sufferers as the pollen impurities are thought to lessen the sensitivity to
hay fever (see Medical Applications below).
- Chunk honey Honey packed in widemouth containers consisting of one or more pieces of comb honey surrounded by
extracted liquid honey.
- Strained honey or filtered honey Honey which has been passed through a mesh material to remove particulate
material (pieces of wax, propolis, other defects) without removing pollen. Preferred by the
health food trade - it may have a cloudy appearance due to the included pollen, and it also tends to crystallize more quickly
than ultrafiltered honey[citation needed].
- Ultrafiltered honey Honey processed by very fine filtration under high pressure to remove all extraneous solids and
pollen grains. The process typically heats honey to 150-170 degrees to more easily pass through the fine filter. Ultrafiltered
honey is very clear and has a longer shelf life, because it crystallizes more slowly due to the high temperatures breaking down
any sugar seed crystals, making it preferred by the supermarket trade. Ultrafiltration eliminates nutrionally valuable enzymes,
such as diastase and invertase[citation needed].
- Heat-Treated honey Heat-treatment after extraction reduces the moisture level and destroys yeast cells. Heating
liquefies crystals in the honey, too. Heat-exposure does also result in product deterioration, as it increases the level of
hydroxymethylfurfural (HMF) and reduces enzyme (e.g. diastase) activity. The heat does also affect sensory qualities and reduces
the freshness. Heat processing can darken the natural honey color (browning), too. [1]
- Ultrasonicated honey Ultrasonication is a non-thermal processing alternative for honey. When honey is exposed to
ultrasonication, most of the yeast cells are destroyed. Yeast cells that survive sonication generally lose their ability to grow.
This reduces the rate of honey fermentation substantially. Ultrasonication does also eliminate existing crystals and inhibit
further crystallization in honey. Ultrasonically aided liquefaction can work at substantially lower temperatures of approx. 35 °C
and can reduce liquefaction time to less than 30 seconds.[2]
Other descriptions
- Churned honey or creamed honey See whipped honey.
- Crystallized honey Honey in which some of the glucose content has spontaneously crystallized from solution as the
monohydrate. Also called "granulated honey."
- Honey fondant See whipped honey.
- Organic honey is honey produced, processed, and packaged in accordance with national regulations, and certified as
such by some government body or an independent organic farming certification organization. For example, in the United Kingdom, the standard covers not only the origin of bees, but also the siting of the apiaries.
These must be on land that is certified as organic, and within a radius of 4 miles from the apiary site, nectar and pollen
sources must consist essentially of organic crops or uncultivated areas[3].
- Set honey All honey will eventually set or granulate and this process can be reversed by gently warming the honey to
remelt it. Some honeys set naturally with large granules and taste a little like granulated sugar in honey. Others set like
royal icing - very hard and unspreadable. To overcome this problem beekeepers will mix in a
small amount of fine-grained honey before it sets and then gently stir the honey to fix the setting prematurely, before it
becomes hard, thereby producing a "soft set" honey.
- Spun honey See whipped honey.
Honey in history, culture and folklore
In many cultures, honey has associations that go far beyond its use as a food. In language and literature, religion and folk
belief, honey is frequently a symbol or talisman for sweetness of every kind.
Honey collection
Honey collection by humans is an ancient activity. Bee Wilson (2004) states that humans began hunting for honey at least
10,000 years ago. Bee Wilson (2004: p.5) evidences this with a depiction a line drawing of a Mesolithic rock painting showing two honey-hunters collecting honey and honeycomb from a wild nest. The two
men are naked and employ a long wobbly ladder which appears to be made out of a kind of grass in
order to reach the wild nest. Both men carry baskets or bags. This rock painting is on a wall in a cave in Valencia, Spain.
Biblical Period
The Old Testament contains many references to honey. While the book of Exodus famously describes the Promised Land as a 'land flowing with
milk and honey' (33:3) the original Hebrew (devash) actually refers to the sweet syrup
produced from the juice of the date. In The Book of Judges, Samson found a swarm of bees
and honey in the carcass of a lion (14:8). In Matthew 3:4, John the Baptist is said to
have lived for a long period of time in the wilderness on a diet consisting of locusts and wild honey. The word "honey" appears
61 times in the King James Version of the Bible.[citation needed]
In Jewish tradition, honey is a symbol for the new year – Rosh Hashana. At the
traditional meal for that holiday, apple slices are dipped in honey and eaten to bring a sweet new year. Some Rosh Hashana greetings show honey and an apple, symbolizing the feast. In some congregations, small straws
of honey are given out to usher in the new year.
Buddhism
Honey plays an important role in the festival of Modhu Purnima, celebrated by
Buddhists in India and Bangladesh. The day commemorates Buddha's making peace among his disciples by
retreating into the wilderness. The story goes that while he was there, a monkey brought him
honey to eat. On Modhu Purnima, Buddhists remember this act by giving honey to monks. The monkey's gift is frequently depicted in Buddhist art.
Mediterranean region
During the Roman Empire, honey was used instead of gold to
pay taxes.[citation needed]
In some parts of Greece, it was formerly the custom for a bride
to dip her fingers in honey and make the sign of the cross before
entering her new home. This was meant to ensure sweetness in her married life, especially in her relationship with her
mother-in-law.[citation needed]
In the accounts of the Ancient Egyptian Pharaoh Seti I, one
hundred pots of honey were equivalent in value to an ass or an ox.[citation needed] Ancient Egyptian and
Middle-Eastern peoples also used honey for embalming the
dead.[19]
Scythians, and later the other Central Asian nomadic people, for many months drove a wagon with a deceased ruler around the
country in their last rites mourning procession, carrying the body in a casket filled with honey.[citation needed]
After his death in battle, the head of Vlad III Ţepeş (of later Dracula fame) was cut off and presented to the Sultan of Turkey, preserved in a jar of honey.[citation needed]
Western culture
In Western culture, bears are depicted as eating honey,
even though most bears actually eat a wide variety of foods, and bears seen at beehives are usually more interested in bee larvae
than honey. [20] Honey is sometimes sold in a bear-shaped
jar. Teddy bears are associated with honey, possibly because of
the influence of Winnie-the-Pooh.[citation needed]
"Honey", along with variations like "honey bun" and "honeypot" and the abbreviation "hon," has become a term of endearment in
most of the English-speaking world. In some places it is used for loved ones; in others, such as the American South, it is used when addressing casual acquaintances or even strangers.
Islamic tradition
The Qur'an mentions rivers of honey in paradise.[21]
"And thy Lord taught the bee to build its cells in hills, on trees and in (men's) habitations...there issues from within their
bodies a drink of varying colours, wherein is healing for mankind. Verily in this is a Sign for those who give thought".[22]
There is an entire Surah in Qur'an called (the Bees) al-Nahl. According to the hadith of
Bukhari, Muhammad liked honey and other sweet
things.[23] Muhammad
strongly recommend honey for healing purposes.[citation needed]
Modern use of honey
In 2005, China, Turkey and the US were the top producers of natural honey, reports the Food and Agriculture Organization of
the United Nations (FAO). [24]
The main uses of honey are in cooking, baking, as a spread on breads, and as an addition to various beverages such as tea and as a sweetener in
commercial beverages such as Sprecher's root
beer.
Honey is the main ingredient in the alcoholic beverage mead, which is also known as "honey wine"
or "honey beer" (although it is neither wine nor beer). It is also used as an adjunct in beer. Beer brewed with more than 30% honey as a source of sugar by weight, or mead brewed with
malt (with or without hops), is known as braggot.[citation needed] Modern microbrews of this style
typically call their product "honey beer" instead, however, as "braggot" is an unfamiliar word to most English
speakers.[citation needed]
Its glycemic index ranges from 31 to 78 depending on the variety. (http://www.rirdc.gov.au/reports/HBE/05-027.pdf)
Ethical concerns
Some vegetarians and vegans avoid using honey because
it is an animal product, instead choosing sweetening alternatives such as
sugar, maple syrup, agave
nectar, rice syrup, dried fruit or stevia.[4] Bees are killed and hurt due to the human manipulation of beekeeping for industrial production.[5]
Medicinal uses and health effects of honey
For at least 2700 years, honey has been used to treat a variety of ailments through topical application, but only recently
have the antiseptic and antibacterial properties of honey been chemically explained. As an antimicrobial agent honey may have the
potential for treating a variety of ailments. One New Zealand researcher says a particular type of honey may be useful in
treating MRSA.[25] Antibacterial properties of honey are the result of the low
water activity causing osmosis, hydrogen
peroxide effect,[26] and high acidity.[27]
Osmotic effect
Honey is primarily a saturated mixture of two monosaccharides. This mixture has a low water activity; most of the water
molecules are associated with the sugars and few remain available for microorganisms, so it is a poor environment for their
growth.
Hydrogen peroxide
Hydrogen peroxide in honey is activated by dilution. However, unlike medical hydrogen peroxide, commonly 3% by volume, it is
present in a concentration of only 1 mmol/l in honey. Iron in honey oxidizes the oxygen free radicals released by the hydrogen peroxide.
- glucose + H2O + O2 → gluconic acid + H2O2
When used topically (as, for example, a wound dressing), hydrogen peroxide is produced by dilution with body fluids. As a
result, hydrogen peroxide is released slowly and acts as an antiseptic.
In diabetic ulcers
Topical honey has been used successfully in a comprehensive treatment of diabetic ulcers when the patient cannot use other
topical antibiotics.[28]
Acidity
The pH of honey is commonly between 3.2 and 4.5.[27] This relatively acidic pH level prevents the growth of many bacteria.
Nutraceutical effects
Antioxidants in honey have even been implicated in reducing the damage done to the colon in colitis.[29] Such claims are consistent
with its use in many traditions of folk medicine.[30]
Other medical applications
Some studies suggest that the topical use of honey may reduce odors, swelling, and scarring when used to treat wounds; it may
also prevent the dressing from sticking to the healing wound.[27]
Honey has been shown to be an effective treatment for conjunctivitis in rats.[31]
Honey (especially when combined with lemon) is often taken orally by pharyngitis and
laryngitis sufferers, in order to soothe them.[citation needed]
Though widely believed to alleviate allergies, local honey has been shown to be no more effective than placebos in controlled
studies.[32] This may be due to the fact that most
seasonal allergies are caused by tree and grass pollens, which honeybees do not collect.
Precautions
Due to the natural presence of botulinum endospores in honey, children under one year of age should not be given honey. The more developed digestive
systems of older children and adults generally destroy the spores. Infants, however, can contract botulism from honey.[33]
Honey produced from the flowers of rhododendrons, mountain laurels, sheep laurel and azaleas may cause Honey Intoxication. Symptoms include dizziness, weakness, excessive perspiration, nausea and
vomiting. Less commonly, low blood pressure, shock, heart rhythm irregularities and convulsions may occur, with rare cases
resulting in death. Honey Intoxication is more likely when using "natural" unprocessed honey and honey from farmers who may have
a small number of hives. Commercial processing, with pooling of honey from numerous sources generally dilutes any toxins.[34]
Toxic honey may also result when bees are in close proximity to tutu bushes (Coriaria
arborea) and the vine hopper insect (Scolypopa australis).[citation needed] Both are found throughout New
Zealand. Bees gather honeydew produced by the vine hopper insects feeding on the tutu plant. This introduces the poison tutin
into honey. Only a few areas in New Zealand (Coromandel Peninsula, Eastern Bay of Plenty and the Marlborough Sound) frequently
produce toxic honey. Symptoms of tutin poisoning include vomiting, delirium, giddiness, increased excitability, stupor, coma and
violent convulsions. As little as one teaspoon of toxic honey may produce severe effects in humans.[citation needed] In order to reduce the risk of tutin
poisoning, humans should not eat honey taken from feral hives in the risk areas of New Zealand. Since December 2001, New Zealand beekeepers have been required to reduce the risk of producing toxic honey by closely monitoring
tutu, vine hopper, and foraging conditions within 3 km of their apiary.
