Summary

Applicability of oxygen absorbers for extending shelf-life of military ration crackers packaged in hermetically sealed tin cans and stored at 15, 25 and 35 deg C for up to 52 weeks was assessed. Lipid oxidation began immediately after baking. Storage temperature was the major factor affecting the rate of oxygen depletion within the can. Sensory evaluations suggested that crackers stored without oxygen absorbers developed oxidative rancid odours after 24 weeks at 25 and 35 deg C. No oxidative rancid odours were observed after 44 weeks with oxygen absorbers. The onset of oxidative rancid odours correlated with hexanal concentration above 6 mg/kg. Additional means are required to prevent oxidation and to extend shelf-life of crackers stored at 25 deg C or above.
