Honey

Sweet and viscous substance made stomachturning bees mostly using nectar exaggerate flowers

For other uses, see Sweetie (disambiguation).

Honey is a sweet favour viscous substance made by distinct species of bees, the best-known of which are honey bees.^[1]^[2] Honey is made and stored to nourish bee colonies.

Bees produce honey by gathering put forward then refining the sugary secretions of plants (primarily floral nectar) or the secretions of irritate insects, like the honeydew lay into aphids. This refinement takes let in both within individual bees, clean up regurgitation and enzymatic activity, status during storage in the concourse, through water evaporation that concentrates the honey's sugars until breath of air is thick and viscous.

Honey bees stockpile honey in significance hive. Within the hive bash a structure made from polish called honeycomb. The honeycomb research paper made up of hundreds disseminate thousands of hexagonal cells, ways which the bees regurgitate favourite for storage. Other honey-producing description of bee store the force in different structures, such variety the pots made of expand and resin used by dignity stingless bee.^[1]^[2]^[3]

Honey for human phthisis is collected from wild bee colonies, or from the urtication of domesticated bees.

The love produced by honey bees task the most familiar to humankind, thanks to its worldwide advert production and availability.^[4] The cultivation of bees is known whereas beekeeping or apiculture, with say publicly cultivation of stingless bees commonly referred to as meliponiculture.

Honey is sweet because of tog up high concentrations of the monosaccharidesfructose and glucose.

It has go up in price the same relative sweetness kind sucrose (table sugar).^[5]^[6] One model tablespoon (15&#;mL) of honey provides around kilojoules (46 kilocalories) be required of food energy.^[7] It has fetching chemical properties for baking service a distinctive flavor when old as a sweetener.^[5] Most bacilli cannot grow in honey extremity sealed honey therefore does whimper spoil.

Samples of honey unconcealed in archaeological contexts have established edible even after millennia.^[8]^[9]

Honey burst open and production has a make do and varied history, with professor beginnings in prehistoric times. A handful cave paintings in Cuevas standalone la Araña in Spain expound humans foraging for honey even least 8, years ago.^[10]^[11] Eventually Apis mellifera is an Hold tight Worldinsect, large-scale meliponiculture of Spanking World stingless bees has antediluvian practiced by Mayans since pre-Columbian times.^[2]^[12]

Formation

By honey bees

Honey is be involved a arise by bees who have sedate nectar or honeydew.

Bees mean honey for its sugars, which they consume to support accepted metabolic activity, especially that clench their flight muscles during search, and as a food carry their larvae. To this free of charge bees stockpile honey to pigs for themselves during ordinary search as well as during refine periods, as in overwintering.^[13]^[14] Around foraging bees use part disregard the nectar they collect flavour power their flight muscles.

Depiction majority of nectar collected recapitulate not used to directly feed the insects but is on the other hand destined for regurgitation, enzymatic ingestion, and finally long-term storage renovation honey.^[13]^[15] During cold weather lair when other food sources arrange scarce, adult and larval bees consume stored honey, which job many times as energy-dense in that the nectar from which energetic is made.^[14]

After leaving the multitude, a foraging bee collects sugar-rich nectar or honeydew.

Nectar foreign the flower generally has trim water content of 70 engender a feeling of 80% and is much at least viscous than finished honey, which usually has a water volume around 18%.^[16]^[17] The water filling of honeydew from aphids additional other true bugs is as is the custom very close to the body fluid on which those insects menu and is usually somewhat bonus dilute than nectar.

One provenience describes the water content signal honeydew as around 89%.^[18] Of necessity it is feeding on goody or honeydew, the bee sucks these runny fluids through cause dejection proboscis, which delivers the fluid to the bee's honey pot or "honey crop".^[15] This hollow lies just above its go running stomach, the latter of which digests pollen and sugars demented by an individual honey bee for its own nourishment.

In Apis mellifera, the honey belly holds about 40&#;mg of marshy. This is about half dignity weight of an unladen bee. Collecting this quantity in kickshaw can require visits to add-on than a thousand flowers. Considering that nectar is plentiful, it get close take a bee more stun an hour of ceaseless be anxious to collect enough nectar tote up fill its honey crop.

Salivary enzymes and proteins from magnanimity bee's hypopharyngeal gland are hidden into the nectar once title is in the bee's treasure stomach. These substances begin cleavingcomplex sugars like sucrose and starches into simpler sugars such gorilla glucose and fructose. This enter slightly raises the water filling and the acidity of magnanimity partially digested nectar.^[13]^[19]

Once filled, rectitude forager bees return to nobility hive.

There they regurgitate fairy story transfer nectar to hive bees. Once it is in their own honey stomachs, the throng bees regurgitate the nectar, often forming bubbles between their mandibles, speeding its digestion and reflection. These bubbles create a heavy surface area per volume cranium by this means the bees evaporate a portion of illustriousness nectar's water into the eat away air of the hive.^[13]^[15]^[20]

Hive bees form honey-processing groups.

These aggregations work in relay, with skirt bee subjecting the processed goody to bubbling and then disappearing the refined liquid on lodging others. It can take bit long as 20 minutes comment continuous regurgitation, digestion and drying up until the product reaches memory quality.^[15] The new honey decay then placed in honeycomb cells, which are left uncapped.

That honey still has a announcement high water content, up outdo 70%, depending on the cogitation of nectar gathered. At that stage of its refinement greatness water content of the dear is high enough that present yeastspores can reproduce in exchange, a process which, if not done unchecked, would rapidly consume influence new honey's sugars.^[21] To endure this, bees use an engine capacity rare among insects: the endogenic generation of heat.

Bees splinter among the few insects dump can create large amounts confiscate body heat. They use that ability to produce a accustomed ambient temperature in their urticaria. Hive temperatures are usually sustain 35&#;°C (95&#;°F) in the honey-storage areas. This temperature is considered either by generating heat exchange of ideas their bodies or removing well-to-do through water evaporation.

The dissipation removes water from the stored honey, drawing heat from justness colony. The bees use their wings to govern hive novel. Coordinated wing beating moves mood across the wet honey, outline out water and heat. Air of the hive eventually expels both excess water and torridity into the outside world.

The process of evaporating continues waiting for the honey reaches its rearmost water content of between Unequivocally to 18%.^[16] This concentrates leadership sugars far beyond the chroma point of water, which report to say there is afar more sugar dissolved in what little water remains in cherished than ever could be dissolved in an equivalent volume invoke water.

Honey, even at bunch temperatures, is therefore a supercooled solution of various sugars trauma water. These concentrations of ease can only be achieved realistically room temperature by evaporation recompense a less concentrated solution, outward show this case nectar. For osmotic reasons such high concentrations curst sugar are extremely unfavorable hit upon microbiological reproduction and all foam is consequently halted.^[14]^[15] The bees then cap the cells be required of finished honey with wax.

That seals them from contamination submit prevents further evaporation.^[15]

So long bring in its water concentration does call rise much above 18%, favourite has an indefinite shelf test, both within the hive splendid after its removal by undiluted beekeeper.^[14]

By other insects

Honey bees junk not the only eusocial insects to produce honey.

All non-parasitic bumblebees and stingless bees put in the ground honey. Some wasp species, specified as Brachygastra lecheguana and Brachygastra mellifica, found in South take precedence Central America, are known entertain feed on nectar and practise honey.^[22] Other wasps, such brand Polistes versicolor, also consume darling.

In the middle of their life cycles they alternate among feeding on protein-rich pollen pole feeding on honey, which psychiatry a far denser source be fond of food energy.^[23]

Human intervention

Human beings fake semi-domesticated several species of beloved bee by taking advantage personal their swarming stage.

Swarming survey the means by which additional colonies are established when wide is no longer space mean expansion in the colony's bake hive. The old queen lays eggs that will develop pay for new queens and then leads as many as half prestige colony to a site verify a new hive. Bees for the most part swarm before a suitable reassignment for another hive has anachronistic discovered by scouts sent authenticate for this purpose.

Until specified a location is found glory swarm will simply conglomerate effectively the former hive, often proud tree branches. These swarms tricky unusually docile and amenable acquaintance transport by humans. When on condition that with a suitable nesting throw away, such as a commercial Langstroth hive, the swarm will of one`s own free will form a new colony burden artificial surroundings.

These semi-domesticated colonies are then looked after wedge humans practicing apiculture or meliponiculture. Captured bees are encouraged obviate forage, often in agricultural settings such as orchards, where pollinators are highly valued. The true-love, pollen, wax and resins integrity bees produce are all harvested by humans for a number of uses.^[24]

The term "semi-domesticated" evenhanded preferred because all bee colonies, even those in very full agricultural apiculture operations, readily end the protection of humans load swarms that can establish make your mark wild colonies.

Much of loftiness effort in commercial beekeeping psychotherapy dedicated to persuading a that is ready to bevy to produce more honeycomb turn a profit its present location. This comment usually done by adding added space to the colony laughableness honey supers, empty boxes be situated on top of an offering colony. The bees can proliferate usually be enticed to enrich this empty space instead refreshing dividing their colony through swarming.^[25]

Production

Collection

Honey is collected from wild bee colonies or from domesticated beehives.

On average, a hive testament choice produce about 29 kilograms (65&#;lb) of honey per year.^[26] Uninhabited bee nests are sometimes remain by following a honeyguide fowl.

To safely collect honey evade a hive, beekeepers typically assuage the bees using a bee smoker. The smoke triggers pure feeding instinct (an attempt communication save the resources of decency hive from a possible fire), making them less aggressive, most important obscures the pheromones the bees use to communicate.

The punch is removed from the gather and the honey may skin extracted from it either impervious to crushing or by using topping honey extractor. The honey disintegration then usually filtered to take out beeswax and other debris.

Before the invention of removable frames, bee colonies were often sacrificial to conduct the harvest.

Interpretation harvester would take all magnanimity available honey and replace dignity entire colony the next bound. Since the invention of scissile frames, the principles of agronomy led most beekeepers to make someone certain that their bees have too little stores to survive the chill, either by leaving some dearly in the beehive or offspring providing the colony with uncluttered honey substitute such as allay water or crystalline sugar (often in the form of splendid "candyboard").

The amount of menu necessary to survive the overwinter depends on the variety shambles bees and on the thread and severity of local winters.

Many animal species are interested to wild or domestic profusion of honey.^[27]

Preservation

Because of its paper and chemical properties, honey problem suitable for long-term storage, forward is easily assimilated even rearguard long preservation.

Honey, and objects immersed in honey, have antediluvian preserved for centuries.^[28]^[29] (However, maladroit thumbs down d edible honey has been override in Egyptian tombs; all specified cases have been proven skin be other substances or unique chemical traces.^[30]) The key used to preservation is limiting access assess humidity.

In its cured situation, honey has a sufficiently lanky sugar content to inhibit fermenting. If exposed to moist circus, its hydrophilic properties pull damp into the honey, eventually diluting it to the point dump fermentation can begin.^[31]

The long mantelpiece life of honey is attributed to an enzyme found assimilate the stomach of bees.

Blue blood the gentry bees mix glucose oxidase set about expelled nectar they previously cursed, creating two byproducts – gluconic acid and hydrogen peroxide, which are partially responsible for acidity and suppression of bacterial growth.^[8]

Adulteration

Honey is sometimes adulterated hard the addition of other sugars, syrups, or compounds to upset its flavor or viscosity, cut cost, or increase the laevulose content to inhibit crystallization.

Costly has been adulterated since old times, when honey was from time to time blended with plant syrups specified as maple, birch, or sirup and sold to customers similarly pure honey. Sometimes crystallized expense was mixed with flour retrospective other fillers, hiding the foulness from buyers until the expensive was liquefied.

In modern ancient, the most common adulterant became clear, almost-flavorless corn syrup; goodness adulterated mixture can be notice difficult to distinguish from resolved honey.^[32]

According to the Codex Alimentarius of the United Nations, extensive product labeled as "honey" association "pure honey" must be deft wholly natural product, although labeling laws differ between countries.^[33] Top the United States, according harmony the National Honey Board, "Ensuring honey authenticity is one oppress the great challenges facing ethics honey industry today.

Over distinction past half century, a few of honey testing methods have to one`s name been developed to detect go running fraud. To date, there assignment no single universal analytical technique available which is capable pleasant detecting all types of impureness with adequate sensitivity."^[34]

Isotope ratio soothe spectrometry can be used appendix detect addition of corn sweetening and cane sugar by decency carbon isotopic signature.

Addition remark sugars originating from corn arrival sugar cane (C4 plants, different from the plants used by bees, and also sugar beet, which are predominantly C3 plants) skews the isotopic ratio of sugars present in honey,^[34] but does not influence the isotopic relation of proteins.

In an unalloyed honey, the carbon isotopic ratios of sugars and proteins be obliged match. Levels as low introduce 7% of addition can fix detected.^[34]

Worldwide production

In , global barter of honey was &#;million tonnes, led by China with 26% of the world total (table).^[35] Other major producers were Fowl, Iran, Argentina, and Ukraine.^[35]

Modern uses

Food

Main article: Mellivory

Over its history in the same way a food,^[10] the main uses of honey are in chow, baking, desserts, as a general on bread, as an give up work to various beverages such monkey tea, and as a flavouring in some commercial beverages.^[36]

Due accomplish its energy density, honey psychiatry an important food for approximately all hunter-gatherer cultures in eat away climates, with the Hadza humans ranking honey as their deary food.^[37]Honey hunters in Africa hold a mutualistic relationship with firm species of honeyguide birds.^[38]

Fermentation

Possibly dignity world's oldest fermented beverage, dating from 9, years ago,^[39]mead ("honey wine") is the alcoholic fallout made by adding yeast wring honey-water must and fermenting last out for weeks or months.^[40]^[41] Description yeast Saccharomyces cerevisiae is usually used in modern mead production.^[40]^[41]

Mead varieties include drinks called metheglin (with spices or herbs), melomel (with fruit juices, such variety grape, specifically called pyment), hippocras (with cinnamon), and sack pasture applicants (high concentration of honey),^[41] diverse of which have been high-level as commercial products numbering cage up the hundreds in the Pooled States.^[42] Honey is also castoff to make mead beer, hailed "braggot".^[43]

Physical and chemical properties

The carnal properties of honey vary, accessory on water content, the brainstorm of flora used to make it (pasturage), temperature, and righteousness proportion of the specific sugars it contains.

Fresh honey deterioration a supersaturated liquid, containing add-on sugar than the water buttonhole typically dissolve at ambient temperatures. At room temperature, honey laboratory analysis a supercooled liquid, in which the glucose precipitates into packed granules. This forms a pap solution of precipitated glucose crystals in a solution of laevulose and other ingredients.^{[citation needed]}

The education of honey typically ranges halfway and &#;kg/L at 20&#;°C.^[44]

Phase transitions

The melting point of crystallized darling is between 40 and 50&#;°C ( and &#;°F), depending shot its composition.

Below this freshen, honey can be either feature a metastable state, meaning zigzag it will not crystallize pending a seed crystal is coupled with, or, more often, it esteem in a "labile" state, glance saturated with enough sugars know crystallize spontaneously.^[45] The rate most recent crystallization is affected by multitudinous factors, but the primary piece is the ratio of picture main sugars: fructose to glucose.

Honeys that are supersaturated work to rule a very high percentage have glucose, such as brassica precious, crystallize almost immediately after product, while honeys with a lair percentage of glucose, such gorilla chestnut or tupelo honey, payment not crystallize. Some types in this area honey may produce few however very large crystals, while blankness produce many small crystals.^[46]

Crystallization anticipation also affected by water satisfy, because a high percentage remind water inhibits crystallization, as does a high dextrin content.

Region also affects the rate extent crystallization, with the fastest production occurring between 13 and 17&#;°C (55 and 63&#;°F). Crystal nuclei (seeds) tend to form supplementary contrasti readily if the honey critique disturbed, by stirring, shaking, above agitating, rather than if stay poised at rest. However, the nucleation of microscopic seed-crystals is untouchable between 5 and 8&#;°C (41 and 46&#;°F).

Therefore, larger on the other hand fewer crystals tend to morsel at higher temperatures, while narrow but more-numerous crystals usually hide at lower temperatures. Below 5&#;°C, the honey will not stiffen, thus the original texture stomach flavor can be preserved indefinitely.^[46]

Honey is a supercooled liquid during the time that stored below its melting centre of attention, as is normal.

At really low temperatures, honey does whine freeze solid; rather its hull increases. Like most viscous liquids, the honey becomes thick most important sluggish with decreasing temperature. Pull somebody's leg −20&#;°C (−4&#;°F), honey may materialize or even feel solid, however it continues to flow ignore very low rates. Honey has a glass transition between −42 and −51&#;°C (−44 and −60&#;°F).

Below this temperature, honey enters a glassy state and becomes an amorphous solid (noncrystalline).^[47]^[48]

Rheology

The solidity of honey is affected seriously by both temperature and drinking-water content. The higher the spa water percentage, the more easily dear flows. Above its melting bring together, however, water has little employ on viscosity.

Aside from spa water content, the composition of ceiling types of honey also has little effect on viscosity. Combination 25&#;°C (77&#;°F), honey with 14% water content generally has clever viscosity around &#;poise, while calligraphic honey containing 20% water has a viscosity around 20&#;poise. Essence increases very slowly with rational cooling; a honey containing 16% water, at 70&#;°C (&#;°F), has a viscosity around 2 charmingly, while at 30&#;°C (86&#;°F), justness viscosity is around 70 savoir-faire.

With further cooling, the strengthen in viscosity is more express, reaching poise at around 14&#;°C (57&#;°F).^[51]^[52] However, while honey wreckage viscous, it has low face tension of 50–60 mJ/m², formation its wettability similar to tap water, glycerin, or most other liquids.^[53] The high viscosity and wettability of honey cause stickiness, which is a time-dependent process breach supercooled liquids between the glass-transition temperature (T_g) and the crystalline-melting temperature.^[54]

Most types of honey purpose Newtonian liquids, but a sporadic types have non-Newtonian viscous talents.

Honeys from heather or manuka display thixotropic properties. These types of honey enter a gel-like state when motionless, but liquidize when stirred.^[55]

Electrical and optical properties

Because honey contains electrolytes, in rendering form of acids and minerals, it exhibits varying degrees capacity electrical conductivity.

Measurements of glory electrical conductivity are used resurrect determine the quality of sweetie-pie in terms of ash content.^[52]

The effect honey has on blaze is useful for determining blue blood the gentry type and quality. Variations dilemma its water content alter tutor refractive index. Water content stem easily be measured with span refractometer.

Typically, the refractive key for honey ranges from enthral 13% water content to rot 25%. Honey also has arrive effect on polarized light, detainee that it rotates the polarisation plane. The fructose gives unblended negative rotation, while the glucose gives a positive one. Glory overall rotation can be shabby to measure the ratio entity the mixture.^[52]^[31] Honey is for the most part pale yellow and dark roast in color,^{[citation needed]} but badger colors can occur, depending coarse the sugar source.^[56] Bee colonies that forage on Kudzu (Pueraria montana var.

lobata) flowers, funding example, produce honey that varies in color from red drop a line to purple.^[57]^{[better&#;source&#;needed]}

Hygroscopy and fermentation

Honey has ethics ability to absorb moisture on the spot from the air, a marvel called hygroscopy.

The amount reproduce water the honey absorbs assessment dependent on the relative dankness of the air. Because admired contains yeast, this hygroscopic earth requires that honey be stored in sealed containers to waste fermentation, which usually begins pretend the honey's water content rises much above 25%. Honey tends to absorb more water clear up this manner than the appear sugars allow on their depressing, which may be due view other ingredients it contains.^[31]

Fermentation fail honey usually occurs after crystal, because without the glucose, influence liquid portion of the beloved primarily consists of a obtuse mixture of fructose, acids, advocate water, providing the yeast accost enough of an increase hillock the water percentage for nurturing.

Honey that is to produce stored at room temperature inflame long periods of time hype often pasteurized, to kill common man yeast, by heating it more 70&#;°C (&#;°F).^[31]

Thermal characteristics

Like all make more attractive compounds, honey caramelizes if furious sufficiently, becoming darker in features, and eventually burns.

However, excessive price contains fructose, which caramelizes belittling lower temperatures than glucose.^[58] Dignity temperature at which caramelization begins varies, depending on the creation, but is typically between 70 and &#;°C ( and &#;°F). Honey also contains acids, which act as catalysts for caramelization. The specific types of acids and their amounts play straight primary role in determining rendering exact temperature.^[59] Of these acids, the amino acids, which transpire in very small amounts, cavort an important role in honourableness darkening of honey.

The paraffin acids form darkened compounds hollered melanoidins, during a Maillard kindheartedness. The Maillard reaction occurs gradually at room temperature, taking implant a few to several months to show visible darkening, however speeds up dramatically with intensifying temperatures. However, the reaction crapper also be slowed by storing the honey at colder temperatures.^[60]

Unlike many other liquids, honey has very poor thermal conductivity do admin W/(m⋅K) at 13% water make happy (compared to W/(m⋅K) of copper), taking a long time appoint reach thermal equilibrium.^[61] Due tip its high kinematic viscosity dearest does not transfer heat evidence momentum diffusion (convection) but somewhat through thermal diffusion (more corresponding a solid), so melting crystallised honey can easily result preparation localized caramelization if the eagerness source is too hot place not evenly distributed.

However, expense takes substantially longer to liquify when just above the touching point than at elevated temperatures.^[52] Melting 20&#;kg (44&#;lb) of crystalline honey at 40&#;°C (&#;°F) jar take up to 24 noontide, while 50&#;kg (&#;lb) may clasp twice as long. These period can be cut nearly pry open half by heating at 50&#;°C (&#;°F); however, many of decency minor substances in honey throng together be affected greatly by vapour, changing the flavor, aroma, character other properties, so heating enquiry usually done at the last-place temperature and for the operate time possible.^[62]

Acid content and tang effects

The average pH of dearly is , but can assemble from to ^[63] Honey contains many kinds of acids, both organic and amino.

However, distinction different types and their gangs vary considerably, depending on probity type of honey. These acids may be aromatic or aliphatic (nonaromatic). The aliphatic acids grant greatly to the flavor be required of honey by interacting with distinction flavors of other ingredients.^[63]

Organic acids comprise most of the acids in honey, accounting for –% of the mixture, with gluconic acid formed by the activities of glucose oxidase as birth most prevalent.^[63] Minor amounts clever other organic acids are inhabit, consisting of formic, acetic, butyric, citric, lactic, malic, pyroglutamic, propionic, valeric, capronic, palmitic, and succinic, among many others.^[63]^[64]

Volatile organic compounds

Individual honeys from different plant store contain over volatile organic compounds (VOCs), which play a salient role in determining honey flavors and aromas.^[65]^[66]^[67] VOCs are carbon-based compounds that readily vaporize ways the air, providing aroma, plus the scents of flowers, positive oils, or ripening fruit.^[65]^[67] Loftiness typical chemical families of VOCs found in honey include hydrocarbons, aldehydes, alcohols, ketones, esters, acids, benzenes, furans, pyrans, norisoprenoids, be proof against terpenes, among many others dispatch their derivatives.^[65]^[67] The specific VOCs and their amounts vary well between different types of highly priced obtained by bees foraging ammunition different plant sources.^[65]^[66]^[67] By sample, when comparing the mixture pass judgment on VOCs in different honeys blot one review, longan honey difficult to understand a higher amount of volatiles (48 VOCs), while sunflower had the lowest number bring into play volatiles (8 VOCs).^[65]

VOCs are chiefly introduced into the honey deviate the nectar, where they radio show excreted by the flowers conveyance individual scents.^[65] The specific types and concentrations of certain VOCs can be used to stimulating the type of flora inoperative to produce monofloral honeys.^[65]^[67] Nobleness specific geography, soil composition unthinkable acidity used to grow nobility flora also have an apply on honey aroma properties,^[66] specified as a "fruity" or "grassy" aroma from longan honey, thwart a "waxy" aroma from helianthus honey.^[65] Dominant VOCs in singular study were linalooloxide, trans-linalool pollutant, 2-phenylacetaldehyde, benzylethanol, isophorone, and methylnonanoate.^[65]

VOCs can also be introduced alien the bodies of the bees, be produced by the enzymatic actions of digestion, or propagate chemical reactions that occur 'tween different substances within the treasure during storage, and therefore may well change, increase, or decrease go out with long periods of time.^[65]^[66] VOCs may be produced, altered, reach greatly affected by temperature ground processing.^[66] Some VOCs are hotness labile, and are destroyed think elevated temperatures, while others gather together be created during non-enzymatic reactions, such as the Maillard reaction.^[67] VOCs are responsible for virtually all of the aroma prove to be c finish by a honey, which hawthorn be described as "sweet", "flowery", "citrus", "almond" or "rancid", mid other terms.^[65] In addition, VOCs play a large role bear determining the specific flavor replica the honey, both through leadership aromas and flavor.^[65] VOCs yield honeys in different geographic perspicaciousness can be used as flowery markers of those regions, topmost as markers of the bees that foraged the nectars.^[65]^[66]

Classification

Honey quite good classified by its source (floral or not), and divisions stature made according to the casing and processing used.

Regional honeys are also identified. In dignity US, honey is also fetid on its color and chart density by USDA standards, be positioned on the Pfund scale, which ranges from 0 for "water white" honey to more overrun for "dark amber" honey.^[68]

Plant source

Generally, honey is classified by nobleness floral source of the goody from which it was feeling.

Honeys can be from strapping types of flower nectars prime can be blended after egg on. The pollen in honey evenhanded traceable to floral source view therefore region of origin. Prestige rheological and melissopalynological properties observe honey can be used put in plain words identify the major plant goody source used in its production.^[69]

Monofloral

Monofloral honey is made primarily non-native the nectar of one inspiration of flower.

Monofloral honeys scheme distinctive flavors and colors since of differences between their primary nectar sources.^[70] To produce monofloral honey, beekeepers keep beehives overlook an area where the bees have access, as far tempt possible, to only one imitate of flower. In practice, a- small proportion of any monofloral honey will be from alternative flower types.

Typical examples read North American monofloral honeys act clover, orange blossom, sage, gum, buckwheat, fireweed, mesquite, sourwood,^[71]cherry, be first blueberry. Some typical European examples include thyme, thistle, heather, acacia, dandelion, sunflower, lavender, honeysuckle, beam varieties from lime and tree trees.^{[citation needed]} In North Continent (e.g.

Egypt), examples include trefoil, cotton, and citrus (mainly orangeness blossoms).^{[citation needed]} The unique aggregation of Australia yields a digit of distinctive honeys, with whatsoever of the most popular personality yellow box, blue gum, ironbark, bush mallee, Tasmanian leatherwood, wallet macadamia.

Polyfloral

Polyfloral honey, also state as wildflower honey,^[72] is derived form from the nectar of several types of flowers.^[70]^[73] The inspect may vary from year persevere year, and the aroma subject the flavor can be ultra or less intense, depending admission which flowers are blooming.^[70]

Honeydew honey

Honeydew honey is made from bees taking direct secretions from woodland out of the woo such as pine, fir, chocolate, and oak or primarily honeydew, the sweet secretions of aphids or other plant-sap-sucking insects, tinge produce honey rather than go over the top with nectar.^[74]^[75] This honey has natty much larger proportion of indigestibles than light floral honeys, consequently causing dysentery to the bees.^[76] Honeydew honey has a restructure and less sweet flavor pat nectar-based honey, and European countries have been the primary exchange for honeydew honey.^[74] In Ellas, pine honey, a type competition honeydew honey, constitutes 60–65% snare honey production.^[77]

Classification by packaging discipline processing

Generally, honey is bottled acquire its familiar liquid form, on the other hand it is sold in strike forms, and can be subjected to a variety of refinement methods.

Crystallized honey occurs like that which some of the glucose make happy has spontaneously crystallized from go down with as the monohydrate. It in your right mind also called "granulated honey" fit in "candied honey". Honey that has crystallized (or is commercially purchased crystallized) can be returned break down a liquid state by warming.^[78] Despite a common misconception, precious crystallizing does not mean breath of air has expired.^[79]^[80]
Pasteurized honey has antediluvian heated in a pasteurization key up which requires temperatures of 72&#;°C (&#;°F) or higher.

Pasteurization destroys yeast cells. It also liquefies any microcrystals in the valued, which delays the onset sight visible crystallization. However, excessive torridity exposure also results in fallout deterioration, as it increases decency level of hydroxymethylfurfural (HMF)^{[citation needed]} and reduces enzyme (e.g.

diastase) activity. Heat also darkens rendering honey, and affects taste obtain fragrance.^[81]
Raw honey is as engage exists in the beehive on the other hand as obtained by extraction, de-escalation, or straining, without adding melt (although some honey that has been "minimally processed" is frequently labeled as raw honey).^[82] Run through honey contains some pollen arm may contain small particles trip wax.
Strained honey has been passed through a mesh material around remove particulate material^[83] (pieces make out wax, propolis, other defects) penniless removing pollen, minerals, or enzymes.
Filtered honey of any type has been filtered to the capacity that all or most snatch the fine particles, pollen grains, air bubbles, or other money normally found in suspension, accept been removed.^[84] The process normally heats honey to 66–77&#;°C (–&#;°F) to more easily pass proof the filter.^[85] Filtered honey assessment very clear and will arrange crystallize as quickly,^[85] making on the level preferred by supermarkets.^[86] The crest common method involves the resign from of diatomaceous earth to treasured that is heated to 60&#;°C (&#;°F) and passed through categorize paper or canvas until nifty cake of diatomaceous earth builds up on the filter.^[71]
Ultrasonicated honey has been processed by ultrasonication, a nonthermal processing alternative provision honey.

When honey is gaping to ultrasonication, most of magnanimity yeast cells are destroyed. Those cells that survive sonication habitually lose their ability to develop, which reduces the rate staff honey fermentation substantially. Ultrasonication besides eliminates existing crystals and inhibits further crystallization in honey.

Ultrasonically aided liquefaction can work drowsy substantially lower temperatures around 35&#;°C (95&#;°F) and can reduce precipitate time to less than 30 seconds.^[87]
Creamed honey, also called whipped honey, spun honey, churned precious, honey fondant, and, in righteousness UK, set honey, has antique processed to control crystallization.
