摘要
In this study the survival and growth patterns of Escherichia coli O157:H7, Salmonella Typhimurium and Listeria monocytogenes in various concentrations of black carrot juice were investigated during incubation period at 4 degrees C and 37 degrees C for 7 days. Several parameters, such as juice concentration (%), pH, incubation temperature (degrees C) and time (days) were found effective on the survival of pathogens tested. Although L monocytogenes has been found to be the less resistant microorganism to the variable conditions, there were only ca. 1 and 2 log reductions in the number of the cells in the juice samples incubated at 4 degrees C for 2 and 7 days, respectively. Incubating at low temperature (4 degrees C) enhanced the survival of test microorganisms. (C) 2011 Elsevier B.V. All rights reserved.
