There are many methods of propolis extraction depending on the desired end product.
- Add 50gms of raw propolis to 1 litre 70% ethanol (cover to prevent evaporation).
- Shake the content intermittently, and allow it to stay for 4-5 days.
- The solution will turn brown or dark colour.
- Filter to remove residue and evaporate to reduce the ethanol content.
- Place hive scrapings containing propolis on a heat-proof container, add enough water to cover propolis and heat this in a 200°F oven.
- The wax will melt and float on the water, while the propolis will stick to the bottom of the container.
- Stir often to help release the wax and maintain the heat for at least two hours.
- Remove the container from the oven and let it cool.
- Remove the waxy layer that forms on the surface of water. Pour off the water and save the coloured mass beneath it.
- Place the container of propolis in a freezer, when the propolis is brittle, chip the granules from the container.
- Spread the granules on paper to dry. Store them in a sealed container.
- Pollen pellets are removed from the bees before they enter the hive using pollen traps.
- Pollen is then dried to less than 10% moisture content as soon as possible after harvesting.
- The pollen is dried using a regular bulb suspended high enough above a pollen tray to avoid it being heated to more than 40-45ºC.
- Pollen can also be dried using solar. It should however be covered to avoid direct sunlight or overheating.
