Abstract
The aim of this work was to explore the influence of various commercial additives, bacteriocinogenic Leuconostoc mesenteroides E131, spices and herbs extracts on the microbiota of minced meat packaged in a modified atmosphere. Different combinations of additives were applied: sodium acetate (E262), sodium citrate (E331), sodium ascorbate (E301), ascorbic acid (E300), silicium dioxide (E551), calcium lactate (E327) and ethyl laurolyl arginate (E243) with spice and herb extracts. The total viable count, lactic acid bacteria, enterobacteria, enterococci, coliforms, coagulase-negative staphylococci and Escherichia coli were monitored during the storage of MAP minced meat at 2.5 ºC for 8 days. Compared to control samples, meat with additives showed lower total viable count and enterobacteria count on the 7th day, and coagulase-negative staphylococci on the 8th day of storage. The highest reduction of E. coli, coliforms, coagulase-negative staphylococci, enterobacteria and total viable count was observed using the formulation consisting of E262, E327, E243, herb extract and E551. Leuconostoc mesenteroides E131 did not show any significant impact on the microbial population of cold-stored minced meat in a modified atmosphere.
