PURPOSE:To provide propolis powder not getting pasty, retaining its original powdery state even in midsummer, not impairing its effect with the propolis component preserved stably, and suppressed in volume increment to the minimum. CONSTITUTION:The contents inside pollen skin are taken out, and the pollen skin is then precipitated in a propolis solution prepared by dissolving propolis component in a solvent to fill the inside of the pollen skin with the solution. Subsequently, the resultant pollen skin is taken out and the solvent inside the pollen skin is evaporated to fill the inside of the hollow pollen skin with the propolis component. |
