Effect of several humectants and potassium sorbate on the growth of Zygosaccharomyces bailii in model aqueous systems resembling low sugar products

The effect of solute type (glucose and polyols) and potassium sorbate (KS) level on the growth of Zygosaccharomyces bailii was evaluated in model aqueous systems resembling low sugar products. Growth curves were modeled using Gompertz equation. Parameters of the models were estimated and applied to...
