Honey, a naturally sweet substance, has been enjoyed by humans for millennia. Its unique flavor and long shelf life are the result of a fascinating natural process carried out by honey bees. Understanding how this golden liquid is made offers insights into the intricate relationship between flowering plants and these industrious insects.
Floral Origins of Nectar
The journey of honey begins with nectar, a sugary liquid produced by plants. Nectar is a sugary liquid containing various sugars, proteins, and other compounds. Plants produce nectar in specialized glands called nectaries, which are found within flowers. The purpose of nectar is to attract pollinators, such as bees, hummingbirds, and butterflies, to facilitate the plant’s reproduction.
Honey bees locate flowers and collect nectar using their long, straw-like tongues, known as proboscises. They suck up the sweet liquid, which is then stored in a special organ called the honey stomach, or crop, located in their abdomen. Bees prefer nectar with a sugar content of at least 15 percent.
The Bee’s Role in Production
Once a foraging bee has collected a load of nectar, it returns to the hive. The honey stomach is distinct from the bee’s digestive stomach, acting as a temporary storage sac where initial processing of the nectar begins. While in the honey stomach, the nectar mixes with enzymes secreted from the bee’s salivary glands.
An enzyme introduced at this stage is invertase, which breaks down the complex sugar sucrose, abundant in nectar, into simpler sugars: glucose and fructose. This enzymatic transformation is a step in converting nectar into honey. Upon returning to the hive, the foraging bee regurgitates the partially processed nectar and passes it to other worker bees, whose role is to continue the honey-making process. This transfer from bee to bee helps to further reduce the water content and continues the enzymatic breakdown of sugars.
Honey’s Journey to the Comb
After being passed among worker bees, the transformed nectar is deposited into the hexagonal cells of the honeycomb. At this point, the liquid still contains a high percentage of water. To reduce this moisture content, worker bees fan their wings over the open cells. This fanning action creates air currents that evaporate excess water, gradually thickening the nectar into honey.
The bees continue this fanning process until the honey reaches a low moisture content. This lower water content prevents fermentation and preserves the honey. Once the honey has reached the appropriate consistency and moisture level, the bees cap the cells with a thin layer of beeswax. This capping seals the honey, protecting it from moisture absorption and external contaminants, ready for long-term storage within the hive.
