As the pH increased from 3, 4, 5, to 6, the amount of dissolved oxygen of the dressing decreased (α= 0.05). When the temperature increased from 10, 20 to 30 °C, the amount of dissolved oxygen decreased (α= 0.05). With the temperature increase from 30 to 40, 50 °C, the amount of dissolved oxygen increased. As the concentration of glucose increased from 0 to 0.5%, the amount of dissolved oxygen decreased (α= 0.05). There was no difference (α= 0.05) in dissolved oxygen reduction among the samples containing 0.5, 1.0, 1.5, or 2.0% glucose.
