Apis mellifera is a species of eusocial honey bee in the family Apidae, widely distributed across Europe, Africa, and western Asia and now introduced globally due to its importance in agriculture and food production. It is commonly known as the Western honey bee. The genus name Apis is Latin for “bee,” while the species epithet mellifera combines Latin mel (“honey”) and ferre (“to bear” or “to carry”), meaning “honey-bearing”. This species has been domesticated for thousands of years and is one of the most economically important insects in the world.

Apis mellifera lives in highly organized colonies consisting of a single reproductive queen, numerous sterile female workers, and male drones. Worker bees perform tasks such as foraging for nectar and pollen, producing wax, caring for larvae, and defending the hive. Through specialized behaviors and enzymatic processes, nectar collected from flowering plants is converted into honey and stored in wax combs. The species inhabits a wide range of environments, from forests and grasslands to agricultural and urban settings, and is a key pollinator for many wild and cultivated plants.

Apis mellifera produces several important ingredients, most notably honey, beeswax, royal jelly, propolis, and bee pollen. Honey is produced by enzymatic transformation of nectar, involving enzymes such as invertase and glucose oxidase, which convert sucrose into glucose and fructose and generate small amounts of hydrogen peroxide. It is consumed worldwide as a natural sweetener and preservative, used in beverages, baked goods, sauces, and traditional preparations. Beeswax is used in food glazing and confectionery, while pollen and royal jelly are consumed in some cultures as nutritional supplements. In addition, some cultures in Asia, Africa, and Mesoamerica consume bee larvae as a nutritious, creamy and nutty delicacy rich in protein.

Chemically, honey contains a mixture of simple sugars (primarily fructose and glucose), organic acids such as gluconic acid, amino acids, and trace enzymes. Bioactive compounds include flavonoids, phenolic acids, and hydrogen peroxide–producing systems that contribute to antimicrobial activity. Honey is strongly odorous and flavored, with characteristics depending on floral source, and is relatively heat stable in terms of sugar composition, though heating can degrade enzymes and volatile aroma compounds. Other bee-derived products contain additional bioactive substances, such as antimicrobial resins in propolis and nutrient-rich proteins and lipids in royal jelly.
