Comparing the resistances
of individual and composited inocula, the inactivation rates of
cocktailed acid-adapted E. coli O157:H7 and spoilage yeasts were
greater than that of any individual strain or species tested.
Furthermore, the tested spoilage yeast composite exhibited greater
resistance towards ultrasound inactivation, and hence may be used
as appropriate target organisms in the establishment of a process
schedule for safe and shelf-stable products. The study is currently
applying the established processes and shall be establishing their
effects on the nutritional and sensory quality attributes of apple
juice and similar products.
