Measurement and correlation of solubilities of oxygen in aqueous solutions containing galactose and fructose

The solubilities of oxygen in aqueous solutions containing galactose and fructose were measured by a saturation method. These sugars are usually included in the fermentation media. The measurements were carried out at 298.15, 303.15 and 310.15 K, as these temperatures are close to the fermentation conditions. tended scaled-particle theory proposed by Hu et al. (1985), of which flexibility for correlation of gas solubilities was exhibited, was used to correlate the solubilities of oxygen in the solutions measured in this work. By determining the potential parameters for sugars, good correlation results were obtained.
