per cm2 to more than 6 log cfu per cm2 at 4 C. In our study, we
could show that the yeast had a high spoilage potential in the
vacuum-packaged beef products, with discoloration, off-odors and
gas swelling occurring as spoilage symptoms. Thus, we could show
for the first time that this microorganism is the major spoilage
microorganism of cold stored, vacuum-packed beef products. It
contributes to considerable economic losses, which are manifested
by defects in organoleptic properties and hence a reduced shelf life
of these products.
