Powdered infant formula is susceptible to oxidation in the presence of oxygen. Even though the product is usually packaged in nitrogen atmosphere, the oxygen ingress through the package layer may occur in case of flexible pouches and affects the oxidation of the product. O2 barrier of the package is thus important variable to protect the product from oxidative deterioration. O2 barrier property was investigated for aluminum-laminated small pillow packs of 3.5×17.5 cm. Storage temperature and combination of primary and secondary packages were evaluated as variables affecting the barrier for conditions of empty pouch flushed with nitrogen. Apparent oxygen transmission rate of the primary package exposed to air was 2.32×10-3 mL (STP) atm-1 d-1 at 30°C and its temperature dependence could be explained by activation energy of 28.5 kJ mol-1 in Arrhenius relationship. The additional secondary package of nylon/PE film containing 20 primary packages was ineffective in modulating package O2 transmission and was only marginally helpful when combined with oxygen scavenger. The same was true in suppressing the product oxidation when the primary package was filled with 14 g of the formula.
