ABSTRACT

This study aimed to develop marinade formulas based on by-products from the dairy, berry, and fruit industries and apply them to lamb meat (LM) treatments to improve the safety and quality characteristics of the meat. To fulfil this aim, six marinade (M) formulations were created based on acid whey (AW) fermented with Lacticaseibacillus casei (Lc) and Liquorilactobacillus uvarum (Lu), either alone or combined with freeze-dried apple (AP) or blackcurrant (BC) pomace. The most appropriate fermentation times for the marinades were selected according to the lower pH values and higher viable LAB counts in the samples. Additionally, the antimicrobial activity of the selected marinades against pathogenic and opportunistic bacterial strains was tested. The characteristics of the LM were analysed after 24 and 48 h of treatment, including physicochemical, technological, and microbiological parameters, as well as overall acceptability. It was established that, after 48 h of fermentation, all of the tested marinades, except M-AWLuBC, had lactic acid bacterial counts > 8.0 log10 CFU·mL-1 and pH values < 3.74. The broadest spectra of pathogen inhibition were observed in the M-AWLuAP and M-AWLuBC marinades. The latter formulations improved the water holding capacity (WHC) and overall acceptability of the LM, while, in the LM-AWLcAP samples, histamine, cadaverine, putrescine, tryptamine, and phenylethylamine were not formed. Lastly, LM treatment with the M-AWLcAP and M-AWLuAP formulas for 48 h achieved the highest overall acceptability (9.04 and 9.43), tenderness (1.53 and 1.47 kg·cm-2) and WHC (2.95% and 3.5%) compared to the control samples.

ABSTRACT

The present study aims to evaluate the effect of Romanov breed lamb gender on carcass traits and meat quality parameters, as well as on the formation of biogenic amines (BAs) and malondialdehyde during meat storage. Obtained results revealed that lamb gender had a significant influence on sternum/breastbone, ribs, right shoulder, and bones of the back leg. Significantly higher lightness (by 3%) was found for male meat; however, higher redness of female meat was observed (by 7.7%). In all cases, a lower pH was obtained for female meat. Significantly higher cooking loss (by 38%) was found for male meat. However, gender was not a significant factor in lamb meat proximate composition, or for BAs and cholesterol content. The gender of animals had a significant influence on 10-heptadecenoic (C17:1), linoleic (C18:2n - 6), total polyunsaturated FA, and total trans isomers content in meat. A significantly higher concentration of malondialdehyde was found in female lamb meat (by 43.4% and 56.8% in fresh and after 3 months of storage at -18°C, respectively) compared to males. Finally, the obtained results supplement the scarce database about the characteristics of Romanov breed meat of different gender and this is beneficial for lamb breeders and meat industry in order to obtain a better quality production.

ABSTRACT

The aim of this research was to perform comparison studies of the chemical, physical, technological, and microbiological characteristics, including biogenic amines (BAs) and volatile compounds (VC), of the European roe deer (RDM), boar (BoM), red deer (ReDM), and beaver (BM) hunted wild game meat (HWGM). The outcome of this study showed a significant effect (p < .05) of animal species on protein content, pH, drip loss, shear force, cooking loss, color coordinates, total count of enterobacteria, and most of the VC. ReDM had the highest protein content (23.15%), cooking loss, L* and b* values. The lowest protein and cholesterol content and L* value and the highest pH, shear force, drip loss, and fat content were established in BM having the highest content of unsaturated fatty acids (UFA) (64.12% from total FA). The total UFA content in ReDM and BM was almost twofold higher, compared with saturated FA. Small amounts of main BAs (<7.8 mg/kg) were found in ReDM and BM, while a higher content of putrescine in RDM and BoM was established. The main VCs in HWGM were acetoin, pelargonic, and acetic acid. These findings provide a valuable data about the HWGM quality characteristics and might aid food manufacturers to improve and enhance the processing of the HWGM.
