<p>The invention relates to a method for producing storage-stable solutions from pelargonium extracts, characterized in that the oxygen quantity at atmospheric pressure in the head space of the package used to store the solution of pelargonium extract is reduced to a maximum of 0.025 parts by volume (preferably 0.015 parts by volume, especially preferably 0.005 parts by volume) per volume part of the solution, wherein the content of proanthocyanidines and 2H-1-benzopyran-2-ones after 9 months of storage at 25°C and a relative humidity of 60% is reduced by a maximum of 10 weight % each (preferably a maximum of 7 weight %, especially preferably a maximum of 5 weight %, particularly a maximum of 3 weight %).</p> |
