Propolis Processing

There are many methods of propolis extraction depending on the desired end product.

Propolis Extract 

Method

  • 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. 

Propolis Granules:

  • 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 processing

  • 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.
