Notes:
An apparatus was developed which measured oxygen permeation from a gaseous environment into a liquid medium. Oxygen permeating the package material was detected in the liquid phase by an oxygen electrode. The oxygen permeation of 1 mil oriented polypropylene was 1417 cc/m2 day at 25°C. Slopes of permeation lines were related to the oxygen solubility of various aqueous media. The oxygen solubility of an air-saturated 1.5% NaCl solution was 7.15 ppm O2. Permeability and solubility values were both within 3% of known standards. The solubility method was used to determine the oxygen concentration of air-saturated single-strength tomato juice. At 25°C, the sample contained 7.3 ppm O2.
