Honey !!!

Honey is a sweet fluid produced by honey bees (and some other species) 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.

Honey gets its sweetness from the monosaccharides fructose and glucose and has approximately the same relative sweetness as that of granulated sugar (97% of the sweetness of sucrose, a disaccharide). Honey has attractive chemical properties for baking, and a distinctive flavor which leads some people to prefer it over sugar and other sweeteners.

Most micro-organisms do not grow in honey because of its low water activity of 0.6. However, honey frequently contains dormant endospores of the bacterium 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 (see Potential health hazards below).

The study of pollens and spores in raw honey (melissopalynology) can determine floral sources of honey. 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.

A main effect of bees collecting nectar to make honey is pollination, which is crucial for flowering plants.

Beekeepers encourage overproduction of honey within the hive so that the excess can be taken without endangering the bees. When sources of food for the bees are short, beekeepers may have to give the bees supplementary nutrition. Supplementary nutrition usually comes in the form of sugar (sucrose) mixed with water at proper ratios.

Formation of Honey

Honey is created 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. By contriving for bee swarms to nest in artificial hives, people have been able to semi-domesticate the insects, and harvest excess honey. In the hive there are three types of bee: a single female queen bee, a seasonally variable number of male drone bees to fertilize new queens, and some 20,000 to 40,000 female worker bees. The worker bees raise larvae and collect the nectar that will become honey in the hive. Leaving the hive, they collect sugar-rich flower nectar and return. In the process, they release Nasonov pheromones. These pheromones lead other bees to rich nectar sites by “smell”. Honeybees also release Nasonov pheromones at the entrance to the hive, which enables returning bees to return to the proper hive.

In the hive the bees use their “honey stomachs” to ingest and regurgitate the nectar a number of times until it is partially digested. The bees work together as a group with the regurgitation and digestion until the product reaches a desired quality. It is then stored in honeycomb cells. After the final regurgitation, the honeycomb is left unsealed. However, the nectar is still high in both water content and natural yeasts which, unchecked, would cause the sugars in the nectar to ferment. The process continues as 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. This reduction in water content raises the sugar concentration and prevents fermentation. Ripe honey, as removed from the hive by a beekeeper, has a long shelf life and will not ferment if properly sealed.

Nutrition

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%), making it similar to the synthetically produced inverted sugar syrup which is approximately 48% fructose, 47% glucose, and 5% sucrose. Honey’s remaining carbohydrates include maltose, sucrose, and other complex carbohydrates. Honey contains trace amounts of several vitamins and minerals. As with all nutritive sweeteners, honey is mostly sugars and is not a significant source of vitamins or minerals. Honey also contains tiny amounts of several compounds thought to function as antioxidants, including chrysin, pinobanksin, vitamin C, catalase, and pinocembrin. The specific composition of any batch of honey will depend largely on the mix of flowers available to the bees that produced the honey.
