antimicrobial solutions in meat products due to its immediate bactericidal and strong, but short-term,bacteriostatic effects on L. monocytogenes. Combinations of nisin with acetic acid, sodium diacetate, and potassium benzoate may be more effective than those with lactic acid, sodium acetate and potassium sorbate, respectively. Specifically, nisin with 3 g/100 ml sodium diacetate or 3 g/100 ml potassium benzoate may be the most promisingcombinat ions in dippingsolution s,
given that benzoate had no effect on bologna pH while diacetate at 3 g/100 ml reduced the pH less than equal
concentrations of acetic or lactic acid. Preventive sprayingwith, or dipping in, nisin solutions may assist
in controlling L. monocytogenes duringslicing , packaging and storage of processed meats, especially if combined, as appropriate, with organic acids or salts.
