Antimicrobial Activity of Binary and Ternary Mixtures of Vanillin, Citral, and Potassium Sorbate in Laboratory Media and Fruit Purées
The susceptibility of Escherichia coli, Salmonella enteritidis, Saccharomyces cerevisiae, and Zygosaccharomyces bailii to binary and ternary mixtures of potassium sorbate (KS), vanillin (V), and citral (C) was evaluated according to the Berenbaum experimental design, in laboratory media. For some V/...
