  • 포장 유통 의무화의 실행과 아울러 닭고기 부분육 포장제의 도입과 관련되어 포장 방법의 차이가 국내산 닭고기 가슴살의 저장 중 품질 특성의 변화의 구명을 위해 포장 방법을 달리한 즉, 공기가 함유되어 있는 상태에서 포장한 함기 포장과 공기가 통하지 않게 봉합한 진공 포장 및 접시 형태의 스티로폼에 넣고 랩으로 포장한 랩 포장으로 처리구들을 분류하여 냉장 저장하면서 닭고기의 품질 특성을 측정하였다. 일반 성분 분석 결과, 수분 함량과 단백질 함량 및 조회 분 함량은 처리구들간에 차이가 없었으나, 조지방 함량의 경우, 함기 포장한 처리구가 다른 진공 포장과 랩 포장 처리구에 비해 높게 나타났다(P<0.05). 또한, 저장 기간별 pH 분석 결과, 함기 포장과 진공 포장과는 달리 랩 포장 처리구에서 저장 기간이 증가할수록 높은 pH 값을 보여주며, 5일차에 비해 10일차에서 현저히 증가하는 것으로 나타났다(P<0.05). 명도와 적색도 값은 모든 처리구에서 저장 기간이 길어질수록 증가하며, 저장 3일과 5일차까지는 랩 포장에서 함기 포장이나 진공 포장에 비해 높은 명도 값을 나타내었으나, 저장 10일차에는 랩 포장에서 낮게 나타났다(P<0.05). 또한, 포장 방법에 따라 함기 포장이나 진공 포장에서 랩 포장에 비해 전 저장 기간에 높은 적색도 값을 나타내었다(P<0.05). 지방산패도 및 단백질 변성 분석 결과, 모든 처리구에서 저장 기간이 증가할수록 높은 값을 나타내며, 특히 5일차까지의 모든 처리구에서 단백질 변형 값은 20 mg% 이상으로 나타났다. 지방산패도 값 또한 10일차에는 급격히 증가하여 0.82~1.05 mgMA/kg의 함량을 나타내었으며, 처리구들간의 비교시 진공 포장 처리구가 가장 낮은 지방산패도 값이 나타났다. 따라서 이상의 결과들을 종합해 보면, 우리나라에서 생산되는 닭고기의 유통기간을 고려해 본다면 관행적으로 이루어지고 있는 랩 포장의 경우 도계 후 3일 이내의 판매 및 유통이 모두 이루어져야 할 것이며, 이와 달리 진공 포장의 경우 저장 기간을 함기 포장이나 랩 포장에 비해 2~3일 정도 연장시킬 수 있을 것으로 판단되나, 모든 포장 방법들에서 저장 및 유통 과정 중 위생적 취급 또한 요구된다.

  • This study was conducted to investigate the dietary effects of germinated and fermented (with Monascus pupureus) soybean screenings (GFS) on growth performance and meat quality in broiler chicken. A total of 750 1-day-old Ross ${\times}$ Ross male broiler chicks were randomly allocated into five groups (five replications with 30 birds each) and fed experimental diets for 5 wks as follows: Group 1, negative-control (antibiotics-free diet); Group 2, positive-control (negative-control with 10 ppm of Avilamycin); Group 3, negative-control with 0.3% GFS; Group 4, negative-control with 0.5% GFS; Group 5, negative-control with 1% GFS. The final body weight of each group fed a diet containing 1% GFS was significantly higher than that of the negative-control group. The feed conversion ratios of all groups fed diets containing GFS and the positivecontrol group were significantly improved compared to the negative-control group during the whole period (p<0.05). The relative weights of various organs along with the activities of serum glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not influenced by the dietary treatments. The levels of total serum cholesterol in groups fed diets containing 0.5% and 1% GFS were more significantly lowered compared to those of the control groups without GFS (p<0.05). There were no significant differences in the cecal microflora profiles among the groups. Further, the dietary treatments did not influence the physico-chemical properties of the edible meat, including the shear force, pH, meat color (CIE $L^*$, $a^*$ and $b^*$), and content of malondialdehyde (MDA). Cooking loss of breast muscle in the groups fed GFS was significantly lowered compared to that of the negative control group (p<0.05). These results indicate that dietary GFS could improve growth performance in broiler chicken and may affect meat quality in some instances.

  • This study investigated the possible improvement in the antioxidative status and quality characteristics of ready-to-eat (RTE) Samgyetang after adding various black garlic (BG) extracts. The antioxidant activity, total phenolic content (TPC), total flavonoid content (TFC), meat quality indexes, and lipid oxidation rates were measured after receiving one of five different treatments consisting of conventional Samgyetang broth as a negative control, raw garlic (RG) extract as a positive control, BG, oven-dried BG, and maltodextrin-encapsulated BG extract as treatments. Employing retort cooking, fat trimmed carcasses were added to the initially prepared broth together with a phenolic extract that was set at 5% (w/w). A significant intensification of red and yellow color was observed in breast and thigh meat treated with BG extracts, regardless of pretreatment, compared to the negative control and RG. The moisture percentage was affected by the addition of BG extracts, where the encapsulation group retained the highest water content after retorting. In terms of antioxidative status, maltodextrin-encapsulated BG extract was as effective as an oven-dried extract to scavenge free radicals and showed the highest score among samples (p<0.01). The concentration of TFC was found to be the highest and did not differ between encapsulation and oven-dried groups, followed by BG, RG, and the negative control. However, the addition of encapsulated BG extract was the most effective in delaying the formation of malondialdehyde among the samples. Therefore, pre-treatment of BG extract through encapsulation is recommended to develop a higher antioxidative status and quality characteristics of Samgyetang.

  • Objective: This study was to evaluate the interaction of three different light-emitting diode (LED) light colors (white, green, and blue) and three intensities (5, 10, and 15 lx) on slaughter performance, meat quality and serum antioxidant capacity of broilers raised in three-layer cages. Methods: A total of 648 (8-days-old) male broiler chicks (Cobb-500) were randomly assigned in 3×3 factorially arranged treatments: three light colors (specifically, white, blue, and green) and three light intensities (namely, 5, 10, and 15 lx) for 35 days. Each treatment consisted of 6 replicates of 12 chicks. The test lasted for 35 days. Results: The semi-eviscerated weight percentage (SEWP) in 5 lx white was higher than that in 15 lx (p<0.01). The eviscerated weight percentage (EWP) (p<0.05) and water-loss percentage (WLP) (p<0.01) decreased in 10 lx white light than those in green light. Under blue light, the content of hypoxanthine (Hx) in muscle was lower than that under white and green light (p<0.01). The content of malondialdehyde (MDA) in 15 lx blue light was higher than that in 10 lx green light (p<0.05). Light color had an extremely significant effect on thigh muscle percentage, WLP, Hx, and crude protein content (p<0.01). Light intensity had a significant effect on SEWP (p<0.05), EWP (p<0.05), lightness (L*) value (p<0.05), WLP (p<0.01), and the contents of superoxide dismutase (p<0.05), MDA (p<0.01), glutathione peroxidase (p<0.01). Conclusion: Using white LED light with 10 lx light intensity can significantly improve the chicken quality of caged Cobb broilers, improve the content of inosine acid in chicken breast and enhance the antioxidant capacity of the body. We suggest that the broiler farm can use 10 lx white LED light source for lighting in 8 to 42 days.

  • Objective: An experiment was conducted to study the effect of supplementing DL methionine (DL Met) at graded concentrations on performance, carcass variables, immune responses and antioxidant variables in broiler chicken fed folic acid (FA) fortified (4 mg/kg) low-methionine diet. Methods: A basal diet (BD) without supplemental DL Met, but with higher level (4 mg/kg) of FA and a control diet (CD) with the recommended concentration of methionine (Met) were prepared. The BD was supplemented with DL Met at graded concentrations (0%, 10%, 20%, 30%, 40%, and 50% supplemental DL Met of CD). Each diet was fed ad libitum to 10 replicates of 5 broiler male chicks in each from 1 to 42 d of age. Results: Body weight gain (BWG) reduced, and feed conversion ratio (FCR) increased in broilers fed low-Met BD. At 30% and 20% inclusion of DL met, the BWG and FCR, respectively were similar to those fed the CD. Similarly, supplementation of 10% DL Met to the BD significantly increased ready to cook meat yield and breast meat weight, which were similar to those of the CD fed broilers. Lipid peroxidation reduced, the activity of antioxidant enzymes (GSHPx and GSHRx) in serum increased and lymphocyte proliferation increased with increased supplemental DL Met level in the BD. The concentrations of total protein and albumin in serum increased with DL Met supplementation to the BD. Conclusion: Based on the data, it can be concluded that supplemental Met can be reduced to less than 50% in broiler chicken diets (4.40, 3.94, and 3.39 g/kg, respectively in pre-starter, starter and finisher phases) containing 4 mg/kg FA.

  • The objective of this research was to evaluate the effects of dietary supplementation of blood meal (BM) as a source of histidine, and magnesium oxide (MgO) as a catalyst of carnosine synthetase, on carnosine (L-Car) content in the chicken breast muscle (CBM), laying performance, and egg quality of spent old hens. Four hundred eighty laying hens (Hy-Line$^{(R)}$ Brown), 95wk old, were allotted randomly into five replicates of six dietary treatments: T1; 100% basal diet, T2; 100% basal diet+MgO, T3; 97.5% basal diet+2.5% BM, T4; 97.5% basal diet+2.5% BM+MgO, T5; 95% basal diet+5% BM, T6; 95% basal diet+5% BM+MgO. Magnesium oxide was added at 0.3% of diets. The layers were fed experimental diets for 5wk. There were no significant differences in the weekly L-Car content in CBM among all treatments during the total experimental period, but some of the contrast comparisions showed higher L-Car in CBM of T6. The L-Car contents linearly decreased (p<0.01 or p<0.05) as the layers got older except in T4 (p>0.05). There were significant differences in egg weight (p<0.01) and soft and broken egg ratio (p<0.05). The control (T1) was highest in egg weight and T6 was lowest in soft and broken egg ratio. Among the parameters of egg quality, there were significant differences in eggshell strength (p<0.01) and egg yolk color (p<0.05). Magnesium oxide supplementation increased the eggshell strength and BM tended to decrease egg yolk color. Eggshell color, eggshell thickness, and Haugh unit were not influenced by BM and MgO. In conclusion, BM and MgO did not significantly influence the L-Car in CBM of spent layers. The L-Car content rapidly decreased as the layers became senescent. Eggshell strength was increased by MgO supplementation.

  • Identification of the major sources contributing to PM is of importance in order to understand their quantitative contributions to atmosphere. In the viewpoint of the meat cooking in Korea, only a few analyses of organic molecular markers have been conducted due to analytical difficulties. In this study, ten different parts of meat (i.e., blade shoulder, belly, and arm shoulder of pork; ribeye roll, top blade muscle, and short plate of beef; leg quarter, breast, and wing of chicken; duck; mackerel) were pyrolyzed to generate the cooked PM using an electronic heating plate. Generated PM were collected by the pyrolysis sampling system to identify total carbon (TC) using a carbon analyzer and cholesterol using a Liquid chromatography tandem-mass spectrometry (LC-MSMS) based on fragmentor voltage (FV), precursor ion, collision energy, product ion. In addition, oxydative potential (OP) analysis using dithiothreitol (DTT) method were discussed to investigate the toxicity relates. Highly correlated pairwise scatterplots between the cholesterol and TC indicate that oxydative potential was highly associated with different parts of meat. This study provides insight into the meat cooking components of PM, which could be drivers of the oxidative potential relates.
