🐞 Bee Products — Honey, Beeswax, Royal Jelly, Propolis

Bee products have both nutritional and industrial value, linking apiculture with agriculture, health, and rural enterprise systems.

Honey — Composition and Properties

Honey is the primary product of apiculture, produced when forager bees collect flower nectar, add the enzyme invertase (from hypopharyngeal glands), and ripen it in comb cells by reducing moisture content from approximately 70% to below 20%. Mature honey is composed of fructose (38%), glucose (31%), water (17-20%), maltose, sucrose, minerals, vitamins, enzymes (invertase, diastase, glucose oxidase), organic acids, and aromatic compounds. Its physicochemical properties include a pH of 3.2-4.5, specific gravity of 1.35-1.44, and a high refractive index.

Honey possesses antibacterial properties due to hydrogen peroxide production by glucose oxidase, low water activity, and acidic pH. It is classified by floral source (unifloral or multifloral) and graded based on moisture content, HMF (hydroxymethylfurfural) level, diastase activity, and absence of adulteration. India produces over 1,20,000 metric tonnes of honey annually, with major production states being Uttar Pradesh, West Bengal, Punjab, Bihar, and Rajasthan.

Beeswax

Beeswax is secreted as thin scales from the four pairs of wax glands on the ventral side of the abdomen of young worker bees (12-18 days old). It is composed of esters of fatty acids and long-chain alcohols, hydrocarbons, and free fatty acids. Beeswax melts at 62-65 degrees Celsius and is used in cosmetics, pharmaceuticals, candle making, comb foundation manufacturing, polishes, and as a coating in the food industry. One kilogram of beeswax requires bees to consume approximately 6-7 kg of honey for its synthesis.

Royal Jelly

Royal jelly is a milky-white secretion produced by the hypopharyngeal and mandibular glands of nurse bees. It is the exclusive diet of queen larvae throughout development and of all larvae during their first three days. Royal jelly contains 60-70% water, 12-15% proteins (including royalactin, which triggers queen differentiation), 10-16% sugars, 3-6% lipids (especially 10-hydroxy-2-decenoic acid or 10-HDA), vitamins (B-complex), and minerals. It is commercially valued as a health supplement for its purported immunostimulatory, anti-aging, and nutritional properties.

Propolis

Propolis (bee glue) is a resinous substance collected by bees from tree buds and bark, mixed with beeswax and salivary enzymes, and used to seal cracks in the hive, reduce entrances, and embalm foreign objects. It contains resins (50%), waxes (30%), essential oils (10%), pollen (5%), and organic compounds (5%), including flavonoids (pinocembrin, galangin, chrysin) and phenolic acids (caffeic acid phenethyl ester or CAPE). Propolis exhibits strong antimicrobial, antifungal, antiviral, anti-inflammatory, and antioxidant activities, making it valuable in medicine and the health food industry.

Bee Venom

Bee venom (apitoxin) is produced by the acid gland associated with the sting apparatus of worker bees. Its primary active component is melittin, a peptide that constitutes about 50% of dry venom and is responsible for pain and inflammation. Other components include apamin, phospholipase A2, and histamine. Bee venom therapy (apitherapy) is used in traditional and alternative medicine for treating arthritis, rheumatism, and certain inflammatory conditions, though clinical evidence remains limited.

Summary Cheat Sheet

• Honey is the primary bee product with major food and medicinal value.
• Beeswax, royal jelly, propolis, and venom support multiple industries.
• Product quality depends on processing standards and moisture/purity control.
• Diversified bee products improve farm income beyond honey sales.
