Definitions

  • the invention relates to an agent for reducing the bacterial count and stabilizing water and aqueous solutions in food quality, in particular for air humidification, as well as a method for reducing the bacterial count in air and the use of the agent.
  • the contamination of the indoor air is a fundamental problem both in private households as well as in commercial rooms and in the manufacturing sector, especially in food processing companies.
  • the packaging is also subject to exogenous and endogenous germs.
  • a large number of agents for reducing the bacterial count and for stabilizing water are known.
  • the most important active ingredient groups are those based on active oxygen, such as ozone, peroxides or potassium permanganate, or those with a high oxidation potential, such as chlorine or hypochlorite.
  • active oxygen such as ozone, peroxides or potassium permanganate
  • oxidation potential such as chlorine or hypochlorite.
  • the oxidation of the germs in the water results in a strong reduction in the number of germs in the short term - due to the decrease in the oxidation potential, the effect of these agents is only temporary, so that later germination of the sterilized water or air cannot be prevented.
  • agents for reducing the bacterial count and stabilizing water should be bactericidal, fungicidal, virucidal and sporicidal for a short time.
  • chlorination of water has usually been used in the past, i.e. a process in which chlorine gas is passed into water and decomposes there into hypochlorous acid and hydrochloric acid.
  • Ozone has often been used as a disinfectant.
  • Both substances have the disadvantage that they are in the gaseous state and therefore require complex systems for their use.
  • both substances are extremely toxic and therefore require increased precautionary measures.
  • due to the fact that these are gaseous materials their duration of action in the water is short, so that "re-chlorination" must be carried out continuously.
  • Germination in open air systems is particularly problematic, since disinfected air can constantly become contaminated again by supplying additional, new air, which can lead to mass infection.
  • Such problematic germs include, for example, the contamination of air and air conditioning systems with anthrax, which, when taken up through the respiratory tract, leads to the fatal pulmonary anthrax - but also legionella infections, which spread via the air humidity and dust particles. The same applies to flu viruses and other germs from pathogens.
  • DE-A-40 31 664 has disclosed a means of reducing bacterial growth in water, with benzoic acid or its derivatives being used to preserve water. From EP 00103554.2 a means for air disinfection has already become known which treats air in an environmentally friendly manner by aerosols with active substances.

  • the essential oils are usually used in dilutions, especially in those that are soluble in water in order to be able to develop their full effect.
  • Lemon oil is generally known to have germicidal, antiseptic properties and to strengthen the immune system and is also used in aromatherapy. turns.
  • Eucalyptus oil in particular its most important component, antiseptic cineol, is also used for colds, for example, and is well tolerated by the animal and human respiratory tract.
  • Tea tree oil for example, was used 4000 years ago by the Australian natives, among other things, because of its germicidal and antiseptic properties. It works against bacteria, fungi and viruses.

Because the agent has such an anti-microbial effect, it is able to ensure a better shelf life than the nitrogen used hitherto, which, although not itself contaminated, also has no anti-microbial effect.
  • the peroxide content of the solution is important, which also contributes to the destruction of germs:

  • the combination according to the invention keeps the water at a slightly acidic to neutral pH, especially when buffering salts of weak acids or free weak acids. The remedy is therefore longer Exposure time is well tolerated, skin-friendly and respiratory-friendly compared to known materials.
  • One of the preferred food preservatives is a food preservative with growth-inhibiting effects on microorganisms and has a specific spectrum of activity on molds; but it can also suppress the development of yeasts and catalase-positive bacteria. Sorbic acid is approved as a preservative up to 10 g per kg of food.
  • the skin is also well tolerated when used externally, since the skin is more resistant to weakly acidic pH;
  • the skin, mucous membrane / lung surface reacts particularly sensitively when alkali is exposed to it for a long time and is also less resistant to the penetration of germs - since it swells up more.
  • the acid coat of the skin is not alkaline destroyed by the water disinfected with the agent according to the invention, but is supported and a stable pH is adjusted.
