Chicken Breast Meat

The aim of this investigation is to specific shelf life of storage chilled chicken breast meat by filling it with gelatin-sodium alginate edible films which contain lemon peels essential oil (LPO) at various final concentrations. Lemon peels essential oil was prepared by steam distilling, and gelatin-sodium alginate edible films were prepared, and LPO was added by the following percentages (0, 0.5, 1, 1.5, 2 %). These groups were packaged in gelatin-sodium alginate edible films, then preserved at (4±1° C) for 18 days and examined after 0, 3, 7, 11, 14 and 18 days of refrigeration for total count of bacteria, freshness and chemical properties. Freshness analyses included determination of pH value and thiobarbituric acid TBA. Chemical analyses included determination of moisture, ash, fat, and protein content. The samples treated by gelatin-sodium alginate edible films with 2 % LPO had the best quality characteristics during the chilled storage period, thereby samples of chicken breast meat had saved of quality characteristics for 14 days.

For determination of poultry quality shortly after slaughtering, physical criteria (pH-value, conductivity, colour, juice retention) are of importance. However, they are affected by breeding, transport, cooling and the storage period. PH-values of breast meat (genetically structured material) were recorded shortly after slaughtering (15 min p.m.) and differences between breeding line and gender were found (n=5109). The pH1-values ranged from 5.50 to 6.79. Male broilers showed significantly lower pH1-values than female ones (6.02:6.10). There were also significant differences concerning breeding line and gender. Meat quality (PSE, DFD) of broilers can be recorded quickly and accurately determining the pH1-value of breast meat. Threshold ranges to be considered are ? 5.8 (PSE), 5.9-6.2 (standard meat properties) and ? 6.3 (DFD). This classification is not to be compared to the deviation of pork.

Chicken Breast Meat

The combined effects of radiation and sous-vide treatment of chicken breast meat were investigated with respect to survival and growth of Listeria monocytogenes, shelf life, thiamine content, and sensory qualities. Chicken breasts were inoculated with L. monocytogenes 81–861 (105 CFU/g), vacuum-packed, irradiated with electron beam (EB) up to 2.9 kGy, and cooked to an internal temperature of 65.6°C. Sous-vide treatment alone had marginal lethal effect on the L. monocytogenes; the residual inoculum reached 107 CFU/g after 8 weeks at 2°C. However, after the combined treatments of sous-vide and EB at 2.9 kGy, the organism remained undetectable during the 8-week storage period. Parallel studies on uninoculated breast meat revealed that sous-vide samples had a shelf life of less than 6 weeks without EB treatment, whereas samples that were irradiated and then received sous-vide treatment had a shelf life of at least 8 weeks. There was a slight reduction in thiamine levels as a result of the EB treatment, but there was essentially no additional loss of thiamine due to the subsequent sous-vide treatment and storage at 2°C. Electron-beam treatment had very little effect on the odor and flavor of the reheated samples. It was concluded that EB treatment combined with sous-vide treatment can greatly enhance the microbial safety and shelf life of chicken breast meat.

Chicken nuggets were manufactured from either hand deboned chicken breast meat or mechanically deboned chicken meat (MDCM) obtained from backs and necks. The effects of vacuum packaging and sodium acid pyrophosphate (SAPP) on lipid oxidation during 6 weeks of frozen storage were studied. Malondialdehyde (MDA) concentrations, determined by an HPLC procedure, was used as an index of oxidative rancidity. Breast meat nuggets were less prone to oxidation than MDCM nuggets. Vacuum packaged breast meat nuggets containing SAPP exhibited the least oxidative rancidity. However, the addition of SAPP to MDCM nuggets significantly reduced lipid oxidation (P<0.05), and resulted in MDA values not significantly different from the breast meat nuggets without SAPP. Differences in fatty acid composition at the beginning and the end of the storage period indicated that certain long chain polyunsaturated fatty acids were the main sources of oxidative rancidity. Sensory evaluation yielded results which were in close agreement with the MDA data.
