- Bee draws nectar by its tongue (proboscis).
- Collected by hive bees - Deposited in cells in comb.
- Honey is very nutritious and have many medicinal property.
- Used in India since ancient times. Used in Ayurveda.
Ripening of Honey
- Nectar contains 20-40% sucrose whereas fully ripened honey contains < 2% sucrose.
- Sucrose (disaccharide) in nectar is converted by enzyme invertase to Glucose (dextrose) and Fructose (Levulose) (which are monosaccharides), to form honey.
- Invertase is present in nectar itself and in saliva of honey.
- Ripening of honey is by action of enzyme and by evaporation of water by fanning of wings.
- Unripe honey is processed artificially by indirect heating to 145-160 °F for 30 minutes.
Properties of Honey
- Percentage of sugar in honey is 78 %.
- According to FSSAI what can be the maximum sucrose content in honey is 5%.
- Honey containing more than 20% moisture at raw stage is not considered pure. Because honey with a high moisture content has a thin texture and eventually tastes sour as a moisture level of 20% or more will ferment into alcohol.
- Vitamin E is not present in honey.
- Honey of little bee, Apis florea has high content of dextrins and is of medicinal importance.
- An antioxidant called pinocembrin is found in honey.
- Below 14°C dextrose of honey gets granulated.
- pH range of honey is 3.4 to 6.1 i.e. acidic in nature.
- Test for invert sugar is done by Resorcinol and Aniline Chloride Test.
Purity test for honey
- Measure specific gravity of honey using hydrometer.
- If the specific gravity is between
1.25 - 1.44 g/cc
it is pure honey
2. Bees Wax
- Wax glands are present in worker honey bees in the sternum of segment no. 4, 5, 6 and 7.

6. Pollen
- Collects pollen by passing flower to flower. Pollen sticking to body removed.
- Using pollen comb - Packed using pollen press into corbicula.
- A single bee carries 10-30 mg pollen (25% of bee’s wt)
- Dislodge by middle log into cell.
- Mix with honey and store.
- It is considered as Super Food.
