The production of high quality meat and meat products is very important. The aim of this study was to analyze effect of some selected antioxidants and protective bacterial cultures on the safety and quality of minced meat. Selected antioxidants: rosemary extract, taurine, creatine, coenzyme Q10 and protective bacterial cultures Staphylococcus carnosus, Staphylococcus vitulinus were used to improve the safety and quality of minced meat (minced pork and minced beef). Using physical chemical methods (the determination of antioxidant activity, phenolic compounds, peroxide value, fatty acids composition) and microbiological analysis (the evaluation of total number of coliform bacteria and the total number of aerobic bacteria) minced meat samples were tested during the production and storage period. All antioxidants selected and used during the study positively effected antioxidant activity of minced meat, and reduced lipid oxidation in the samples. After 1 day of storage, the acid value in the minced pork sample with rosemary extract was 1.19±0.00 mg KOH/g, and the acid value in the sample without additives was 1.29±0.01 mg KOH/g. The peroxide value in the minced beef sample (after 1 day of storage) with rosemary extract was 1.00±0.02 meq./kg and in the sample without additives was 1.57±0.02 meq./kg. The least antioxidant activity was in the samples without additives. The best antimicrobial properties during the whole study were shown in the minced meat samples with rosemary extract- after 5 days of storage the total number of aerobic bacteria in pork: 4.28±0.10 log10 CFU/g, in beef: 4.23±0.17 log10 CFU/g, when P<0.001 in both cases. The higher number of aerobic bacteria (after 5 days of storage) were determined in the samples without additives: in the minced pork sample 6.87±0.05 log10 CFU/g and in the minced beef sample 5.73±0.02 log10 CFU/g, the less numbers were in the samples with rosemary extract and [...].
