Abstract:

In  this  study,  the antibacterial  effect of  nisin  Z in  the  form of  free and microencapsulated  on the growth of Listeria monocytogenes  in kilka surimi  fish  (Clupeonella cultriventris caspia)  on days 0,  3,  6,  9,  12  and  15 holding period were determined. Concentrations which used for the nisin-free and microencapsulated (by Spray Dryer on covered  liposomes) two concentrations IU 700 and IU 1000 were on gram that with method of spray were added to surimi kilka and one sample as a control (no preservative) is considered. The results showed that the  amount of this  index in treatments  containing microencapsulated nisin, most  significantly  towards  free treatments as well as free treatments were significantly lower compared to the control treatment. Also treatment with 1000 IU nisin microencapsulated  that  was  exposed to the  highest concentrations of microencapsulated nisin form, Most significantly was  less  treatments from the aspect of reputed index than other treatments, but the amount of bacterial  levels were  increased  in all treatments and did not observe an effect of decreasing of bacterial population but effect of nisin in  the form of microencapsulated  in reducing bacterial growth rate was higher than the control and free treatments.
