AIMS Weak acids are widely used by the food industry to prevent spoilage and to inhibit the growth of pathogenic micro-organisms. In this study the inhibitory effects of three commonly used weak acids, acetic acid, benzoic acid and sorbic acid, on the growth of Listeria monocytogenes were investigated. METHODS AND RESULTS In a chemically defined medium at pH 6.4 benzoic acid had the greatest inhibitory effect (50% inhibition of growth at 4 mmol l(-1)), while acetate was the least inhibitory… CONTINUE READING
