To the best of our knowledge there is no data available in the literature regarding the combined use of an ethanol emitter and an oxygen absorber for the preservation of sliced wheat bread. Based on the above, the objective of the presentwork was to study the effect of either an ethanol emitter (EE) or an ethanol emitter combined with an oxygen absorber (EE þ OA) for extending the shelf life of sliced wheat bread. A second objective was to test the experimental
PET-SiOx//LDPE laminate, a high barrier material, for the preservation of sliced wheat bread.
