| Summary: | <p class="MsoNormal" style="text-align: justify; text-justify: inter-ideograph; mso-pagination: none; mso-layout-grid-align: none; text-autospace: none;"><span style="font-size: 10.0pt; mso-ansi-language: EN-US;" lang="EN-US">Púchov salami is favorite fermented salami among Slovak consumers. Nisin is the only bacteriocin accepted by European Commission for a commercial use as additive for food preservation (although not commonly used in meat products). Because of its possibility to prolonge shelf-life of the products and its antimicrobial activity, its effect in dry fermented Slovak salami Púchov<span style="color: red;"> </span>experimentally inoculated with <em>Listeria innocua</em> Li1 strain was checked. The initial number of <em>L. innocua</em> Li1 in the inoculated salami mixtures was 10<sup>4</sup> CFU/g (log 10; 4.04 ± 0 07). After nisin addition, the count of Li1 strain in the meat samples (inoculated with Li1 and treated by nisin) was 1.36±0.07 CFU/g; difference 2.68 logarithmic cycle was noted between Li and Li/Ni samples. At day 2, the difference 3.23 log cycle was detected between Li1 and Li/Ni samples (Li:5.46±0.08, Li/Ni: 2.14±0.07 CFU/g); at weeks 3, 4, it was 1.69 and 1.80 log cycle. Activity of nisin itself was not recovered from the experimental salamis by the analytical method; however, its inhibitory effect was shown by Li1 count decrease. The pH in salamis during processing was almost<span style="color: blue;"> </span>at the same level (5.52, 5.53, 5.55). Water activity was not negatively influenced. Water content in Li/Ni salamis reached almost requested levels (maximum percentage of water requested is 34 %).<br /><br /><span style="font-family: Verdana, sans-serif; font-size: 11.818181991577148px; text-align: start;"><strong>doi:10.5219/218</strong></span></span></p> |
