This study was performed to determine the effects of antimicrobial factors on the growth of Escherichia coli O157: H7 in ground beef. Response surface methodology design was used to determine the effects of temperature (10 ˚C, 15˚C, 20˚C), EDTA (5 mM, 25 mM, 45 mM) and acetic acid concentration (0.25%, 0.75%, 1.25%)on the growth of E. coli O157: H7 in ground beef treated with nisin (10 3 IU/g). A growth curve was fitted by using nonlinear regression of the Gompertz equation, and growth… CONTINUE READING
