Efficacy of GRAS antimicrobial compounds and modified atmosphere packaging in reducing Salmonella, Campylobacter and spoilage organisms on poultry meat

The antimicrobial efficacy of carvacrol, trans-cinnamaldehyde, eugenol and thyme oil (0.5, 1, 2 and 5% v/v) was evaluated against Salmonella on turkey breast cutlets as 2 min dip treatments at 4°C. Carvacrol revealed maximum efficacy against...

T. Nair, Divek Poultry Science <p>The antimicrobial efficacy of carvacrol, <i>trans</i>-cinnamaldehyde, eugenol and thyme oil (0.5, 1, 2 and 5% v/v) was evaluated against <i>Salmonella</i> on turkey breast cutlets as 2 min dip treatments at 4°C. Carvacrol revealed maximum efficacy against Salmonella on turkey cutlets and was selected for 30s and 60s dip treatments at 4°C. Only 5% carvacrol was effective and exhibited 1.0 and 1.8 log CFU/g reduction of <i>Salmonella</i> with 30s and 60s dip treatments, respectively. However, carvacrol showed synergistic activity with carbon dioxide in modified atmosphere packaging (95% CO<sub>2</sub>/5% O<sub>2</sub>) against <i>Salmonella</i> and <i>Campylobacter</i> and caused 1.0-2.0 log CFU/g reductions with lower concentrations (0.25, 0.5 and 1.0%). This combination reduced the growth of lactic acid bacteria. In the third experiment, efficacy of lauric arginate (200 and 400ppm) against <i>C. jejuni</i> was tested on chicken breast fillets. Both these concentrations significantly reduced <i>C. jejuni</i> on chicken fillets (1.0-1.5 log CFU/g) at 4°C.</p> Chander Shekhar Sharma Aaron S Kiess Ramakrishna Nannapaneni MSSTATE 2014-07-25 text application/pdf http://sun.library.msstate.edu/ETD-db/theses/available/etd-07032014-123858/ http://sun.library.msstate.edu/ETD-db/theses/available/etd-07032014-123858/ en restricted I hereby certify that, if appropriate, I have obtained and attached hereto a written permission statement from the owner(s) of each third party copyrighted matter to be included in my thesis, Dissertation, or project report, allowing distribution as specified below.
