Definitions

  • the invention relates to a method for the sterilization of packaging materials for the aseptic filling of fruit juice and wine using sulfurous acid.
  • the invention has for its object to provide a method for the sterilization of packaging materials for the aseptic filling of fruit juice and wine using sulfurous acid, which causes a satisfactory germ killing in a short time.
  • the object is achieved in that the packaging material is treated with aqueous solutions of sulfurous acid and alcohols.
  • Figures 1 to 16 show the killing effect (reduction in the number of bacteria as a function of time) of sulfurous acid and alcohol in each case alone and of mixtures of sulfurous acid and alcohols used against various yeasts, fungi and bacteria.
  • Aqueous mixtures (solutions) of sodium disulfite (Na 2 S 2 O 5 ) and ethanol were used as test substances, ethanol being present in a concentration between 96 and 100%. Since sulphurous acid develops its strongest germicidal effect in a strongly acidic range, the sodium disulfite used was acidified to a pH of 3.0 with citric acid after being dissolved in water.
  • the acidified, alcohol-containing Na 2 S 2 O 5 mixed solution contains not only alcohol but also sulfuric acid in various dissociation stages, the sulfurous acid being the effective antiseptic.
  • the germicidal effect was investigated depending on the concentration at different temperatures.
  • the Mucor mold is even more resistant to H 2 SO 3 than Aspergillus niger, and the Mucor killing time curves at different H 2 SO 3 concentrations and at different temperatures are shown in FIGS.
  • a D value in the range of a few seconds is reached at 30,000 ppm (22 ° C) or at 10,000 ppm (60 ° C).
  • Acetic acid bacteria have a fairly high resistance to sulfurous acid. As can be seen from FIGS. 10 and 11, the acetic acid bacterium Gluconobacter can only be killed slowly. Both a high concentration of H 2 SO 3 and an increase in temperature do not have the germicidal effect to improve significantly. A technically usable rapid germ killing with corresponding D values in the range of a few seconds, preferably less than 3 seconds, is not achieved even at the high concentration of 100,000 ppm at room temperature. The D 22 value here is still 15 seconds.
  • Acetobacter aceti shows high resistance to sulfurous acid. However, rapid kill with a D 50 value of 1.7 seconds can also be achieved with this acetic acid bacterium due to the synergistic effect of the mixed solution sulfuric acid / alcohol (20,000 ppm / 15% by weight) (FIG. 14).
  • Fig. 15 The dependence of the killing time of the lactic acid bacterium Leuconostoc dextranicum on the temperature is shown in Fig. 15. The greatest kill is achieved at 60 ° C with a concentration of 10,000 ppm. The D 60 value here is 1.45 seconds.
  • test results described and shown clearly show a synergistic effect of sulfurous acid and alcohol in killing the germs examined.
  • the combination of sulphurous acid with alcohol enables the H 2 SO 3 concentration, the alcohol content and the Temperature kills the existing germs quickly with D values between 1 and 2 seconds, so that the proposed mixed solution can also be used advantageously on an industrial scale, in particular in the sterilization of plastic-coated packaging materials for fruit juice and no filling or in the sterilization of wine bottles.
  • Ethanol is preferably used as the alcohol, although other alcohols can preferably also be used.
  • the sulfurous acid is preferably present in a concentration of 10,000 to 100,000, in particular 10,000 to 50,000 ppm, based on the mixture.
  • Particularly advantageous alcohol concentrations are in the range of advantageous alcohol concentrations in the range of 10 to 30, in particular 10 to 20% by weight, based on the mixture.
  • By treatment according to the invention are temperatures between 2o and 8 0, preferably 20 and 50 ° C suitable.
  • Sulfuric acid is best obtained by reacting salt-like sulfur compounds with acid.
  • Na 2 SO 3 is also suitable alone or in combination with the aforementioned substance.
  • Citric acid is preferably used as the acid for adjusting the pH.
  • the packaging material can be treated by immersion, spraying or the like with the synergistic mixed solution according to the invention. It is also possible to use that salt-like sulfur compound, e.g. B. Na 2 S 2 O 5 , which provides the sulfurous acid, separately on the packaging material and then dissolve it by adding an acidified, aqueous alcohol solution.
  • salt-like sulfur compound e.g. B. Na 2 S 2 O 5 , which provides the sulfurous acid
  • the invention is particularly advantageous in the case of wine packaging, since wine inherently contains sulfurous acid and alcohol. No "foreign substances" need to be used to sterilize the packaging materials, which could impair the quality of the wine.
