Method for producing storage-stable solutions from pelargonium extracts

Solution production involves reducing oxygen quantity to 0.025, preferably 0.005 volume parts per volume part of the solution at atmospheric pressure in the head area of a container. The container is used for storing the solution of Pelargonium extract. Content is reduced by proanthocyanidin and 2H-1-benzopyran-2-one after 9 months storage at 25[deg] C and a relative air humidity of 60%. The oxygen quantity is reduced by mechanical blowing with an inert gas, by a reduced volume of the head area or by addition of an oxygen-removing agent. The agent consists of one or multiple substances.
