00925njm 22002777a 4500 dc Tamkutė, Laura author Vaicekauskaitė, Rūta author Melero Gil, Beatriz author Rovira Carballido, Jordi author Venskutonis, Petras Rimantas author 2021-03 The effects of different concentrations of defatted by supercritical CO2 chokeberry pomace extracts isolated by consecutive pressurized ethanol and water on the growth of Listeria monocytogenes, Brochothrix thermosphacta, Pseudomonas putida, lactic acid bacteria (LAB), and aerobic mesophilic bacteria (AMB) were tested. The extracts at >3.3% concentration effectively inhibited tested bacteria in their cultures. Heating reduced antimicrobial activity of extract at higher microbial load. Ethanolic extract (2%) inhibited bacteria in pork slurry (inoculated and non-inoculated with bacteria), pork meat burgers, and cooked ham. These results indicate that chokeberry ethanolic extract has great potential as a natural antimicrobial for reducing microbial growth, increasing meat products safety, and extending their shelf life. Consequently, chokeberry pomace extract may be regarded as a promising ingredient, which might be used as an alternative to commercially available synthetic antimicrobials. In addition, chokeberry phytochemicals may provide health benefits to meat products and mitigate the adverse effects of processed meat. Novelty Impact Statement It is the first study, which evaluated the antimicrobial activity of the defatted by supercritical CO2 black chokeberry pomace extracts isolated by consecutive extractions with pressurized ethanol and water. The results showed that the extracts effectively inhibited selected food-borne pathogens and spoilage bacteria both in their cultures and real pork products. The extracts are promising natural ingredients for improving meat safety and shelf-life. 0145-8892 https://hdl.handle.net/10259/11260 10.1111/jfpp.15220 1745-4549 Antimicrobial activity Aronia melanocarpa Berry pomace extract Cooked ham, Pathogenic bacteria Pork hamburgers Spoilage bacteria Black chokeberry (Aronia melanocarpa L.) pomace extracts inhibit food pathogenic and spoilage bacteria and increase the microbiological safety of pork products
