Antibacterial Activity of Selected Essential Oils against Foodborne Pathogens and Their Application in Fresh Turkey Sausages

Abstract

Essential oils (EOs) isolated from different plant materials, namely Origanum majorana L., Satureja hortensis L., and Satureja montana L. (OMEO, SHEO, and SMEO, respectively), were used in fresh turkey sausage processing. The chemical composition and in vitro antimicrobial potential of selected EOs and their mixture were determined. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against foodborne pathogens (Escherichia coli, Salmonella Enteritidis, and Listeria monocytogenes) ranged in the interval of 0.44–7.1 µL/mL. Fresh turkey sausages were produced with EOs addition and marked as follows: TOMEO—0.150 µL/g OMEO; TSHEO—0.150 µL/g SHEO; TSMEO—0.150 µL/g SMEO; TEOM—0.050 µL/g OMEO, 0.050 µL/g SHEO and 0.050 µL/g SMEO, and control (C) (without EOs). Microbiological profile and biogenic amines content in fresh turkey sausages were recorded during storage. The selected EOs and their mixture efficiently reduced bacterial growth and biogenic amines formation and accumulation. The lowest Enterobacteriaceae count and total biogenic amine (BA) concentration were determined through treatment TSHEO. The results of this study show that selected EOs could be useful in fresh turkey sausage processing in order to improve safety and shelf-life.

Effect of Commercial Starter Culture on Physicochemical Properties and Biogenic Amine Formation in Traditional Dry-Fermented Beef Sausage

“…The ripening time significantly influenced (P < 0.05) the concentration of this BA in both batches, as did starter culture inoculation, which resulted in the more intensive accumulation of tyramine in SC samples in the second half of the ripening period. This finding is in accordance with reports of several authors who previously found a highly positive correlation between the concentration of tyramine and the lactic acid bacteria counts in fermented sausages (Dominguez et al, 2016;Ikonić et al, 2023;Šojić et al, 2023).…”

Effect of Alginate Coating Enriched with Postbiotics Derived from Bifidobacterium bifidum Strains on Microbial and Physicochemical Quality of Turkey Breast Meat

“…In the last two decades, poultry meat production has been steadily increasing worldwide. FAO estimates that poultry meat production will reach approximately 151 million tons in 2030 [1]. Turkey meat is a source of low fat and cholesterol content, rich protein, minerals such as calcium, phosphorus, potassium, essential amino acids, and vitamins B1, B2, B6, and B12.…”
