SUBSTANCE: invention relates to a method for sterilization of beverages infected with acetic acid bacteria. Method involves introducing a preserving agent into the beverage, wherein the preservative used is a composition containing: sorbic acid and/or alkali metal and/or alkali-earth metal salt thereof in amount of 100 pts.- to 350 ppm, or benzoic acid and/or its alkali metal and/or alkali-earth metal salts in amount of from 100 pts.to 350 ppm, and dimethyl dicarbonate in amount of 75 ppm to 250 ppm and sulphur dioxide and/or sulphur dioxide releasing agents in amount of 5 ppm to 100 ppm. Alkali metal salt and/or alkali-earth metal salt of sorbic acid can be sodium sorbate, potassium sorbate and lithium sorbate or calcium sorbate or a mixture of said salts, and alkali metal and/or alkali-earth metal salt of benzoic acid is sodium benzoate, potassium benzoate and lithium benzoate or calcium benzoate or a mixture of said salts. Sulphur dioxide-releasing agents are sodium bisulphite, sodium disulphite, potassium hydrosulphite, potassium disulphite, calcium hydrosulphite, calcium disulphite or mixtures of said salts. Processed beverages may be refreshing beverages, for example, cold teas, sports beverages, fruit juices and juice-containing beverages, wherein the processed beverages are beverages infected with acetic acid bacteria selected from the following group Asaia sp., Acetobacter sp., Gluconobacter sp., Gluconacetobacter sp., Saccharibacter sp., Swaminanthia sp., Acidomonas sp., Kozakia sp., Neoasaia sp., Granulibacter sp., Acidocella sp., Acidiphilium sp., Roseococcus sp., Acidosphaera sp. and Rhodopila sp.

EFFECT: invention provides more effective removal of acetic acid bacteria.
