PROPOLIS TREATMENT METHOD
The invention relates to a propolis treatment method, consisting in carrying out at least a first propolis extraction on a batch of raw propolis with a first pure solvent so as to obtain a first extract having first properties. The method may comprise at least a second extraction carried out using a second pure solvent differing in nature from the first, the extraction with the second solvent being carried out on the filtration residues obtained after the extraction carried out with the first solvent, so as to recover and render useable all of the components of the propolis using, furthermore, only biological solvents; and finally the method may include a third extraction, after the second, carried out on the filtration residues obtained after this second extraction, with a third pure solvent different from the other two, the first solvent therefore being water, the second being alcohol and the third being oil. The invention applies to the manufacture of propolis extracts for use in the manufacture of hygiene, care and cosmetic products, and for the manufacture of food products and food supplements.
