Reaction Steps

FIG. 24 shows the combined effect of citral dimethyl acetal, cinnamic acid, sorbic acid and benzoic acid on growth of yeast Saccharomyces cerevisiae X2180-1B in a matrix of tubes of synthetic soft drink, 0% tea. Synthetic soft drink contained glucose, 8%w/v, citric acid 3 g/l, potassium orthophosphate 1 g/l, magnesium chloride 0.1 g/l and yeast extract 0.1 g/l. The matrix of 30 ml tubes each containing 10 ml synthetic soft drink pH 3.4, all contained 100 ppm citral dimethyl acetal. Sorbic acid+Benzoic acid 1:1 ratio, were used in the range 1-250 ppm (e.g. 250 ppm=125 ppm sorbic acid+125 ppm benzoic acid) and cinnamic acid in the range 1-175 ppm. Tubes were inoculated with 104 cells of the yeast Saccharomyces cerevisiae X2180-1B. Tubes were incubated for 14 days at 25° C. to allow surviving yeasts to grow out. At 14 days growth was measured by optical density at 600 nm in x11 diluted samples, and blank values subtracted.
