The aim of this work was to study the growth/survival of acid-adapted cells of Listeria monocytogenes, in orange juice and in minimallyprocessed orange slices. The L. monocytogenes OML 45 behaviour into TSB (Tryptic Soy Broth) medium was evaluated at differentpH values (between 3.7 and 6.7). The acid-adapted cells were obtained maintaining L. monocytogenes in TSB at pH 5.7 for 3 h. Theobtained cells were then inoculated into a diluted orange juice with a pH of 2.6. Moreover, the acid-adapted cells were inoculated intominimally processed orange slices. The growth was evaluated during storage at different temperatures. The study confirms that orangejuice and minimally processed orange slices can support the acid-adapted pathogen growth.
