Interactions Between Additives: Its Effect on Sorbate Stability and Z. bailii Minimum Inhibitory Concentration in Model Aqueous Systems Resembling Salad Dressings

The effect on sorbate stability of several additives (EDTA, ascorbic and acetic acids) frequently present in the formulation of salad dressings, and the minimal inhibitory concentration (MIC) of sorbate concerning Z. bailii growth in the presence of that additives were studied in aqueous model syste...
