Introduction to Bee Products
An overview of the main substances produced by honeybees, their composition, uses, and key considerations.

1. Overview

2. Honey

2.1 Production Process

1. Foraging – Bees collect nectar and store it in the crop.
2. Enzymatic conversion – In the hive, enzymes (invertase, glucose oxidase) break down sucrose into glucose & fructose and produce small amounts of hydrogen peroxide.
3. Water reduction – Repeated regurgitation and evaporation in the honeycomb concentrate the solution to ~18 % water.
4. Capping – Bees seal cells with wax when moisture is low enough for long‑term stability.

2.2 Types (by botanical origin)

• Monofloral – Dominated by one plant source (e.g., Manuka, Acacia, Clover).
• Polyfloral – Mixed nectar from many plants; typical “wildflower” honey.
• Honeydew – From secretions of aphids or other sap‑feeding insects; higher mineral content.

2.3 Key Properties

• Antimicrobial – Low water activity, acidity (pH ≈ 3.5–4.5), hydrogen peroxide, methylglyoxal (Manuka).
• Antioxidant – Phenolic compounds, flavonoids.
• Energy source – Rapidly absorbed glucose + fructose.

3. Propolis

3.1 Composition Highlights

• Flavonoids (e.g., pinocembrin, galangin) – antioxidant, anti‑inflammatory.
• Phenolic acids (caffeic, ferulic) – antimicrobial.
• Essential oils – contribute to scent & bioactivity.
• Waxes & resins – structural matrix.
