Effectiveness of Higher Fatty Acids C8, C10 and C12, Dimethyl Dicarbonate and Sulphur Dioxide for Inhibition of Re-fermentation and Malolactic Activities in Wine

Original language description

This paper is aimed on inhibition of malolactic fermentation and the possibility of prevention of re-fermentation in wine technology and wine storage. Saturated higher fatty acids (HFA) - C8, C10 and C12, dimethyldicarbonate and sulfur dioxide were tested. Experiments have confirmed that addition of sulphur dioxide into the fermenting media causes rapidly inhibition of lactic bacteria metabolic activity. There was found out almost double concentration of dead cells after 24 hours in wine treated with HFA (25.4 %) in opposite to untreated (48.5 %). Combination with 60 mg/L sulfur dioxide came out even better (32.9 to 77.0 %). Optimized properties to inhibit yeasts and lactic acid bacteria with the current potential for treatment of wine against secondary fermentation is likely to offer a mixture of HFA C8, C10 and C12 (2:7:1) dissolved in 70% vol. ethanol, with 100 ml ethanol solution containing 10 g of this mixture. Addition of HFA can significantly reduce the dosage of other preservat
