The addition of glucose oxidase into yogurts during processing has
shown to be a potential option to decrease the oxidative stress in probiotic
yogurts. In general, high counts of viable strains – Lactobacillus
acidophilus and Bifidobacterium longum – and slight changes in some
physicochemical and sensory parameters of yogurts have been observed
along the refrigerated storage. However, any technology solution
aiming at a positive impact on the functional aspects of probiotic yogurts
should not bring additional financial impact, once it may represent a relative
loss ofmarket share. In this context, itwould be interesting to investigate
the effect of glucose oxidase on some quality parameters of
probiotic yogurts packaged in different plastic containers (with different
oxygen permeability transfer rates) throughout the refrigerated storage.
The results of this study may be useful for food companies that produce
functional milk-based products that aim to maintain the viability of the
probiotic bacteria without changing the packaging system
