Abstract The purpose of this study was to investigate the effect of synbiotic and organic acids on oxidative stability of breast broiler meat. The experiment consists on 120, 2 days old Ross 308 chicks, housed in metabolic cages (6 chicks/cage). A 2 x 2 factorial arrangement was considered with 4 treatments and 5 replicates (30 animals per group). Two different levels of synbiotic (0 and 10 g/kg) and two different levels of organic acids (0 and 1.5 g/kg) were added to the standard diets in order to constitute the four experimental diets. For further analysis, breast meat from 6 animals per group were collected in 42nd experimental day. No significant differences were noticed for any oxidative parameter measured in breast samples except TBARS (significant decreased values for OA supplemented groups), at the end of experiment. After 4 days of refrigeration (4°C), the secondary oxidative products (panisidine, TBARS) were significant smaller for E groups, compared to C. After 7 days of refrigeration (4°C), the OA groups had significant smaller values for primary (CD) and secondary oxidation products. Synbiotic and organic acids supplements presented positive effect on meat quality by increasing oxidative stability of breast meat during storage.

In this paper the oxidative stability of cold pressed sunflower oil of high-oleic type was investigated, using Schaal?Oven test at elevated temperature (63?2?C). At the same time samples of linoleic type oils, cold pressed and refined, were tested. The extent of oxidative changes was analyzed regarding the content of primary and secondary oxidation products during the period of 14 days. To especially expressed increase in oxidative values, with very high values of the coefficient of determination occurred in samples of linoleic type of oils, cold pressed and refined, whereas these changes were much less observed in the sample of cold pressed sunflower oil of high-oleic type (R2 ? 0.99). The cold pressed oils of high-oleic and linoleic type, as well of refined sunflower oil of linoleic type were measured and the content of conjugated dienes and conjugated trienes. In the period of 14 days, the lowest increase in oxidative value and the lowest degree of conjugation into the conjugated diene and triene were determined in cold pressed sunflower oil of high-oleic type, indicating a significantly better oxidative stability of this type of oil compared to linoleic types.

The effects of different Spirulina concentrations used alone and in combination with citric acid on the oxidative stability of olive oil were assessed. The amounts of primary and secondary oxidation products produced in Spirulina samples were lower than that of the control. The improved oxidative stability indices of Spirulina samples with and without citric acid were in the range of 85.20–94.47% and 258.10–260.21%, respectively. In comparison with the control, Spirulina samples manifested significantly higher carotenoid and chlorophyll contents at the beginning and end of the storage period. The presence of these bioactive compounds results from the presence of Spirulina in the medium and can thus retard the oxidation of olive oil. A higher oxidative stability was reached using BHT in comparison with Spirulina samples. Furthermore, no synergistic action was observed in possible connections between citric acid and Spirulina. In conclusion, Spirulina can enhance oxidative stability and improve the shelf life of olive oil.

This study aimed to evaluate the performance and meat quality of broilers fed different levels of alpha-tocopherol. A total of 240 one-day-old Cobb 500® male broiler chicks were reared until day 7 of life, as recommended by the commercial line, and were fed at only 50% of the alpha-tocopherol requirement. At day 8, the chicks were weighed, homogenized, and allotted in a completely randomized design with four treatments (50, 100, 150, and 200% alpha-tocopherol requirement) and six replicates of ten chickens per experimental unit. Several variables were evaluated: weight gain, feed intake, feed conversion, carcass yield and prime cuts (drumstick, thigh, and breast), edible viscera (heart, liver, gizzard), immune organs (cloacal bursa and spleen), intestine weight and length, abdominal fat, breast meat color (lightness, redness, and yellowness), pH, cooking loss, and shear force of the breast meat. Dietary alpha-tocopherol levels did not influence broiler performance, carcass yield, and prime cuts at 42 days of age. The edible viscera, immune organs, the length of the small intestine, and the abdominal fat, as well as the meat color (lightness, redness, and yellowness), pH, cooking loss, and shear force of the breast meat, were not influenced. However, the small intestine yield increased linearly with increasing levels of alpha-tocopherol. The dietary levels of alphatocopherol did not influence the performance and meat quality of broilers from 8 to 42 days of age.

There are data in the literature on the influence of higher amounts of organic selenium on production results, and the obtained results indicate that high levels of organic selenium added to feed (even up to 15 mg / kg) of chickens did not have a negative effect on production results. Also, in the literature related to chicken nutrition there is data on the use of different forms (inorganic, organic) and different amounts of selenium on carcass meat, pH value of meat, ability to bind water, chemical parameters of meat quality, oxidative stability of meat, and and on the sensory properties of broiler meat. Of particular importance are the studies of the possibility of using increased amounts of organic selenium in poultry nutrition in order to enrich meat with selenium. This is of particular importance for the nutritional value of meat, and in connection with this, human health. The aim of this study was to investigate the effect of adding different amounts of organic selenium (ALKOSEL® R397) in concentrate mixtures on the sensory properties of meat streams.

Docosahexaenoic acid (DHA) is one of the most important omega-3 polyunsaturated fatty acids, with proven health-promoting properties. However, oils with a very high content in DHA (DHAO) are extremely susceptible to oxidation, which affects shelf stability and limits incorporation in food products. Green tea extracts (GTE) are potential candidates for the protection of these oils, but their use in such oils has not been previously reported. This study investigated the effect of GTE (160 ppm, 400 ppm, 1000 ppm) and α-tocopherol (80 ppm, 200 ppm, 500 ppm) on the oxidative stability of a DHAO over a 9-week storage at 30 °C. The oxidative status was monitored during storage by the measurement of peroxide value (PV) and p-anisidine value (p-AV). Changes in eicosapentaenoic acid (EPA) and DHA content, as well as in catechins and tocopherol contents, were also evaluated. The addition of GTE enhanced the oxidative stability of DHAO by reducing the formation of peroxides and secondary oxidation products, whereas α-tocopherol had no significant effect on the PV of oil during storage but led to a significantly higher p-AV. The EPA and DHA content of DHAO was stable in GTE-supplemented samples whereas a decrease was observed in the control and α-tocopherol-supplemented samples. GTE also delayed the degradation of tocopherols initially present in the oil, while catechins resulting from the addition of GTE decreased progressively during the storage period.

Qualitative characteristics of breast meat of broilers fed diets supplemented with different concentrations (0; 0.3 and 0.5mg kg-1) of selenium in the form of selenomethionine and sodium selenite were analyzed. A total of 1050 one-day-old male Cobb broiler chicks were arranged factorially at random to five treatments (two concentrations x two sources + control diet without addition of selenium) with 7 replications of thirty birds each and received an isonitrogenous and isocaloric diets in all phases according to their ages (1-21, 22-35, and 36-42 days). At 42 days of age, TBARS (thiobarbituric acid reactive substances) after storage at 4ºC for one, seven and 15 days and also after 30 days under freezing temperatures (-15°C), color (CIELab), water holding capacity, cooking loss, shear force, pH and selenium concentration were determined in slaughtered birds breast meat. Results indicated that the use of selenomethionine provides less lightness and lower oxidation in chicken breast meat stored up to 15 days at 4°C. There was a positive effect of dietary different sources and levels of selenium on breast meat quality of broilers. It was observed a linear effect of dietary selenium levels on the amount of selenium deposited in the muscle, and the organic source (selenomethionine) is more effective than inorganic one (sodium selenite) for broiler meat conservation.

ObjectivesIn the broiler industry, high photoperiod (the duration of light exposure per day) regimes have traditionally been utilized to increase yield of breast meat, as well as maximize feed intake and growth rate in the growing period. However, recent literature reports this practice may have adverse effects on broiler welfare, resulting in impaired mobility and increased incidence of leg abnormalities. However, little information available in the current literature regarding effects of photoperiod on meat quality attributes and oxidative stability of broiler meat. Thus, the objective of this study was to evaluate the quality characteristics and lipid/protein oxidative stability of breast meat from broilers that were exposed to different photoperiod combinations.Materials and MethodsA total of 432 Ross 308 broiler chicks were allocated among 4 rooms each subjected to one of the following photoperiod treatments (hours Light: Dark): 20L:4D, 18L:6D, 16L:8D and 12L:12D, with 6 pens per treatment. At d 42, 2 broilers per pen (12 broilers/treatment) were randomly selected, harvested and air chilled for 24 h at 2°C. At l day postmortem, paired breast muscles (M. pectoralis) were collected for the meat quality analyses such as, water-holding capacity (drip/purge/cook loss), Warner-Bratzler shear force (WBSF), and display color for 7 d under fluorescent light (1450 lx). Lipid oxidation was assessed via the TBARS assay and protein oxidation by thiol content measured at d 1 and d 7 of display. The experimental design was randomized complete block design. Data were analyzed using the PROC MIXED procedure of SAS, and means were separated using least significant differences (P < 0.05).ResultsPhotoperiod had no effect on fillet yield and pH (P > 0.05). No significant difference in WBSF was found between treatments, although 12L:12D had a trend of higher WBSF (P = 0.08). Higher moisture loss during carcass chilling was found in carcasses from 20L:4D compared to 16L:8D and 12L:12D treatments (P < 0.05). No other measure of water-holding capacity was affected, though the 16L:8D treatment demonstrated a trend of higher freezing/thawing loss compared to other treatments (P = 0.06). Proximate moisture, protein and lipid contents were unaffected by photoperiod (P > 0.05), but higher ash was observed in 16L:8D over 20L:4D and 18L:6D (P < 0.05). Different photoperiod combinations affected color stability of breast meat during display (P < 0.05). Of note, fillets from 20L:4D maintained highest L* and hue angle, and least a* values (P < 0.05), indicating inferior color stability compared to other treatments. Oxidation increased with display, and fillets from 20L:4D and 18L:6D had higher TBARS over 12L:12D (P < 0.05); no photoperiod effect was observed in thiol content (P > 0.05).ConclusionResults suggest 20L:4D photoperiod regimes may be detrimental to meat quality, as carcasses from this treatment group had higher moisture loss during chilling, and color measurements characterized these fillets as being paler and more discolored than other treatments. Fillets from 12L:12D maintained lower TBARS than 20L:4D and 18L:6D, suggesting photoperiod regimes allowing more hours of dark may be beneficial in improving oxidative stability. Further studies determining the effects of photoperiod on quality and protein functionality of chicken meat for processing technological would be highly warranted.
