This research was conducted to compare the meat characteristics of Korean native duck and imported commercial duck. The Korean native ducks and imported commercial ducks (broiler duck: Grimaud) were raised under identical rearing and feeding conditions for 8 wk and 6 wk, respectively. At the end of the rearing period, ten ducks from each group were slaughtered,and breast and leg meat were obtained 24 h after slaughtering for analyses of meat characteristics. The results showed that the breast of Korean native ducks contained lower moisture and fat, and higher protein and water holding capacity (WHC) than those of imported commercial ducks (p<0.05). The breast of Korean native ducks also had higher CIE a* and lower CIE L* (p<0.05). After cooking, the breast meat of Korean native ducks had higher shear-force, sensory attributes of texture, taste and overall likeness (p<0.05). Also, the breast meat of Korean native ducks contained a higher percentage of palmitic acid (C16:0) and arachidonic acid (C20:4) (p<0.05) than those of imported commercial ducks. Furthermore, the leg meat of Korean native ducks contained higher percentages of total unsaturated fatty acid and lower percentages of total saturated fatty acid (p<0.05). It is concluded that the meat from Korean native ducks, especially breast meat, had better quality parameters and contained higher amounts of unsaturated fatty acids.

The aim of this research is to evaluate the effects of cooking time and storage temperature on the quality of home-made retort pouch packed Chuncheon Dakgalbi. The leg meat of broiler is being cut into cubes and is mixed with the Dakgalbi sauce and vegetables. Around 200 g of Chuncheon Dakgalbi is being stuffed into a retort pouch and then vacuumed. The retort pouch packed Chuncheon Dakgalbi is subjected to cooking (autoclaving) at 110o C and 0.75 Kgf for 10, 20 or 30 min and then transferred to the chilling room at 2o C for rapid cooling procedures. Subsequently, the samples are stored at 4o C or 25o C for 4 wk. According to results of sensory evaluation, the highest sensory scores were found in Chuncheon Dakgalbi which was cooked for 30 min (p<0.05). Prolonged cooking time tends to decrease the pH, CIE L* and CIE a* levels, and slightly promote the lipid oxidation and protein deterioration. The Chuncheon Dakgalbi being cooked for 10 min promoted the lipid oxidation and protein deterioration during storage at 25o C. Moreover, the total aerobic and anaerobic bacteria in Chuncheon Dakgalbi being cooked for 10 min started to grow after 3 wk of storage at 25o C. Cooking (autoclaving) at 110o C for 30 min is able to maintain the quality and shelf-life of retort pouch packed Chuncheon Dakgalbion the market.

본 연구는 산화 촉진 조건에서 한우육의 항산화효소 활성, 지방산화 및 향기패턴의 관계에 관해 구명하고자 실시하였다. $15^{\circ}C/RH$ 100%와 동일한 이산화탄소의 농도(20%)에서 산소의 농도(0%, 25%, 50% 및 75%)에 따라 8일간 저장하면서 가스의 농도, catalase 및 glutathione peroxidase(GSH-Px) 활성, TBARS, 육색 및 향기패턴을 분석하였다. 가스의 농도는 산소 처리구들에서 저장기간 동안 산소의 감소와 이산화탄소의 증가를 보였으며, 총감소량과 총 증가량은 25%>50%>75% 순으로 높았다. Catalase활성은 저장기간 동안 산소 농도에 따른 차이를 보이지 않았으나, GSH-Px 활성은 저장 중 산소의 농도가 증가함에 따라 급격히 감소하여 8일째에는 0%>25%>50%>75%순으로 높게 나타났다(p<0.05). TBARS 함량은 산소의 농도가 증가함에 따라 빨리 촉진되어 저장 2일째부터 0%<25%<50%<75% 순으로 높게 나타났다(p<0.05). 육색은 산소처리구들의 명도($L^*$)가 무산소 처리구보다 높았다(p<0.05).적색도($a^*$)는 저장 0일째에 0%<25%<50%<75% 순으로 높았으나(p<0.05), 2일째부터는 산소 처리구들이 낮았다(p<0.05). 황색도($b^*$)는 산소 처리구들이 높았으며(p<0.05),저장 0일과 8일째에 0%<25%<50%<75% 순으로 높게 나타났다(p<0.05). 전자코에 의한 향기패턴은 저장 8일째에 무산소 처리구와 산소 처리구들간에 뚜렷하게 분별되었다. 따라서 산소의 농도가 증가함에 따라 한우육의 항산화효소, 지방산화 및 육색의 안정성이 현저하게 저하되었으며, 항산화효소 활성 및 지방산화가 향기패턴의 차이에 영향을 미친다고 사료된다. This study was carried out in order to investigate the relationship of antioxidant enzyme activity, lipid oxidation, and aroma pattern of Hanwoo (Korean cattle) beef for 8 d at $15^{\circ}C/RH$ 100% under 0% $O_2$/20% $CO_2/80%\;N_2$, 25% $O_2$/20% $CO_2/55%\;N_2$, 50% $O_2$/20% $CO_2/30%\;N_2$, and 75% $O_2$/20% $CO_2/5%\;N_2$-conditions. The reduction of $O_2$ and the induction of $CO_2$ were shown in the 25-75% $O_2$-groups during storage and total change rates of $O_2$ and $CO_2$ were followed in order: 25%>50%>75%. Catalase activity was not significantly different among all groups. During storage, glutathione peroxidase activity decreased by increasing the $O_2$ concentration and was followed at 8 d in order: 0%>25%>50%>75% (p<0.05). From 2 d of storage, TBARS content had significant (p<0.05) differences in order: 0%>25%>50%>75%. The CIE $L^*$ value was higher (p<0.05) in the 25-75% $O_2$-groups, compared with the 0% $O_2$-group. During the first time, the CIE $a^*$ value was higher (p<0.05) in order: 0%<25%<50%<75% but was lower (p<0.05) in the 25-75% $O_2$-groups from 2 d of storage than in the 0% $O_2$-group. The CIE $b^*$ value was higher (p<0.05) in the 25-75% $O_2$-groups than in the 0% $O_2$-group and had significant (p<0.05) differences at 0 and 8 d in order: 0%<25%<50%<75%. Aroma patterns with the electronic nose were clearly discriminated between the 0% $O_2$-groups and the 25-75% $O_2$-groups at 8 d of storage. Therefore, high oxygen reduced stabilities of antioxidant enzymes, lipid oxidation, and color in Hanwoo beef. Furthermore, antioxidant enzyme activities and lipid oxidation could affect aroma patterns.

연구는 원료육 대비 5% 닭갈비 양념을 첨가한 닭갈비 맛 계육 소시지를 제조하는데 있어서 닭 껍질과 돼지 등지방의 첨가가 저장 중 이화학적 품질을 비교하기 위하여 실시하였다. 닭갈비맛 계육 소시지를 대조구(100% 닭 가슴육), 닭껍질 첨가구(85% 닭 가슴육 + 15% 닭껍질), 돼지 등지방 첨가구(85% 닭 가슴육 + 15% 돼지 등지방)로 나누어 제조하였다. 완성된 닭갈비맛 계육 소시지를 진공포장하여 $4^{\circ}C$에서 14일간 저장하면서 이화학적 품질을 검사하였다. 소시지의 일반 조성을 보면, 대조구에서 수분(72.73%)과 조단백(21.46%) 함량이 높았고, 돼지 등지방 첨가구에서 조지방(10.48%) 함량이 높았다(p<0.05). 대조구와 닭 껍질 첨가구는 돼지 등지방 첨가구보다 불포화지방산 및 단일불포화지방산 함량이 높았다(p<0.05). 보수력은 저장 기간 동안 돼지 등지방 첨가구에서 가장 높은 수준을 보였다(p<0.05). 조직감 비교를 위한 경도는 돼지 등지방 첨가구가 대조구와 닭 껍질 첨가구보다 낮았고, 탄성은 높았다(p<0.05). 결론적으로 닭갈비맛 계육 소시지에 닭 껍질을 첨가하면 불포화지방산 조성이 증가하나, 돼지 등지방 첨가구에 비해 보수성과 조직감이 떨어지는 것으로 나타났다. This study was conducted to investigate the effect of chicken skin and pork backfat on quality of Dakgalbi-taste chicken sausage as fat sources. The sausages were manufactured with 100% chicken breast without fat sources, 85% chicken breast meat with 15% chicken skin or 85% chicken breast meat with 15% pork backfat, respectively. Batters for production of chicken sausage were mixed with 5% Dakgalbi sauce and 4.92% ingredients (meat and lipid basis) for 20 min and then stuffed into casing. All cooked sausages were vacuum-packaged and stored at $4^{\circ}C$ for 14 days. Moisture and crude protein contents were higher in the control, and crude lipid content was higher in chicken sausage with pork backfat (p<0.05). Unsaturated fatty acids content and monounsaturated fatty acids/saturated fatty acids ratio of sausage with pork backfat were lower than those of control and sausage with chicken skin (p<0.05), which were influenced by fatty acids compositions of fat sources. The chicken sausage with pork backfat showed a lower hardness and chewiness, and higher springiness measured by food texture analyzer. The sausage with pork backfat had a high level of water holding capacity (WHC) during storage (p<0.05). In conclusion, Dakgalbi-taste chicken sausage containing chicken skin had higher unsaturated fatty acid compositions, but showed lower textural quality compared with that containing pork backfat.

This study was carried out to investigate the effect of dietary palm oil supplementation on the quality of the carcass and meat of Hanwoo (Korean cattle). Thirty-month-old steers were fed on a concentration with or without (control) palm oil for 3 mon prior to slaughter. The samples of M. longissimus were taken from all carcasses and then stored at 4℃ for 9 d. The carcass traits, total myoglobin content, pH value, total reducing ability, and myofibrillar fragmentation index were unaffected by supplementation with palm oil. However, the fat content, water-holding capacity, and tenderness were significantly increased by dietary palm oil (p

이성기,최원희,무흘리신,강선문,김천제,안병기,강창원,Lee, Sung-Ki,Choi, Won-Hee,Muhlisin, Muhlisin,Kang, Sun-Moon,Kim, Cheon-Jei,Ahn, Byoung-Ki,Kang, Chang-Won 한국축산식품학회 2011 한국축산식품학회지 Vol.31 No.5

토종닭과 육계를 원료육으로 제조한 춘천닭갈비의 품질을 비교하고, 토종닭을 기존 육계의 대체육으로 사용 가능한지를 구명하기 위해 본 실험을 실시하였다. 토종닭은 국립축산과학원이 복원한 엘림농장의 110일령의 우리맛닭 및 (주)하림에서 사육한 70일령의 한협 3호를 이용하였고, 육계는 38일령의 대형 육계(18호) 및 31일령의 소형 육계(16호)를 사용하였다. 품종별 발골한 정육 조각에 닭갈비 양념을 3:1로 혼합하여 함기포장 및 가스조절포장(30% $CO_2$/70% $N_2$-MAP)을 실시하여 $5^{\circ}C$에서 10일간 저장하면서 상호 품질을 비교하였다. 토종닭군은 육계군에 비해 pH는 낮고 가열감량은 높았다(p<0.05). 전단력은 우리맛닭, 한협 3호순으로 토종닭군이 육계군보다 높았다(p<0.05). 다리육의 지방산 분포를 보면, 우리맛닭이 다른 품종에 비해 myristic acid(C14:0), palmitic acid(C16:0), stearic acid (C18:0) 및 포화지방산(SFA)이 높았던 반면, linoleic acid (C18:2n6), linolenic acid(C18:3n3), 불포화지방산(UFA)이 낮았다(p<0.05). n6/n3 지방산 비율은 우리맛닭의 19.24와 한협 3호의 16.77로 육계의 14.02와 14.77보다 높았다(p<0.05). 닭갈비의 관능검사에서 맛과 향은 차이가 없었으나, 조직감과 종합기호도에서 토종닭군이 육계군보다 낮았다. 닭갈비를 가스조절포장으로 저장했을 때 원료육에 따른 품질 차이가 없었지만, 함기포장에 비해 pH가 높고 지방산화(TBARS) 및 휘발성 염기태 질소(VBN)가 낮았기 때문에 저장성이 증대되는 것으로 나타났다. 따라서 토종 닭으로 제조한 춘천닭갈비가 품질과 건강적인 측면에서 기존의 육계보다 상대적으로 불리하다고 판단된다. This study was conducted to evaluate a quality comparison between Chuncheon Dakgalbi made from Korean native chickens (KNC) and that made from commercial broilers. Two Korean native chickens including Woorimatdag (KNCWoori) and Hanhyup3 (KNC-Hanhyup), and two commercial broilers including grades of 18 (Broiler-18) and 13 (Broiler-13) were slaughtered at 110, 70, 38, and 31 d of ages. Chuncheon dalkalbi was prepared by mixing/dipping the meat in chili pepper sauce; it was then packed with air-packaging (Air-P) and 30% $CO_2$-MAP (0% $O_2$/30% $CO_2$/70% $N_2$), and stored at $5^{\circ}C$ for 10 d. The results showed that the KNC group had a lower pH but a higher cooking loss compared with the broiler group (p<0.05). In a texture analysis, KNC-Woori had the highest shear force value among the breeds (p<0.05). For the fatty acid composition of the thigh, the KNC-Woori contained more total saturated acids, myristic acid, palmitic acid and stearic acid, but less total unsaturated fatty acids, linoleic acid and linolenic acid than other breeds (p<0.05). Also, the n6/n3 ratios of the KNC group (19.24 and 16.77) were higher than those of the broiler group (14.02 and 14.77) (p<0.05). The total acceptability scores of Dakgalbi made from the KNC group were decreased by sensory panelists. The Dakgalbi with 30% $CO_2$-MAP delayed the protein deterioration (Volatile basic nitrogen) and lipid oxidation during storage. However, no clear evidence was observed of $CO_2$-MAP on the effect of different chicken materials. It is suggested that 30% $CO_2$-MAP instead of Air-P is used for methods for Chuncheon Dakgalbi. Furthermore, it might be unfavorable to use Korean native chickens as raw material for Chuncheon Dakgalbi from a practical quality point of view.

본 연구는 닭 품종(18일령 브로일러, 49일령 산란종 병아리, 35일령 백세미)별 원료육으로 제조한 춘천 닭갈비의 품질을 비교하고자 실시하였다. 품종간 향기 패턴의 차이는 없었지만, 백세미육 닭갈비가 색깔이 진하고 붉었으며, 저장기간 중에 지방산화 안전성이 높고, 관능검사에 의한 기호성이 높았다. 그러므로 세 품종 중에서 백세미육으로 제조한 춘천 닭갈비의 품질이 가장 우수하였다. This study was conducted to compare the quality of Chuncheon Dakgalbi made with meat from three chicken breeds. Ross male broilers, Hy-Line Brown male chicks and White Mini male broilers were raised for 18 d, 49 d and 35 d, respectively, and slaughtered. The thigh meat from carcasses on each breed were used for this experimented. The fat content was higher in White Mini broiler meat than Ross broiler and HY-LINE BROWn chick meat (P<0.05). No differences were observed in aroma patterns of raw meat and Chuncheon Dakgalbi between all breeds. The Chuncheon Dakgalbi made with White mini broiler meat had higher color stability and lipid oxidation stability and showed higher sensory scores such as visual color and overall acceptability. Therefore, the Chuncheon Dakgalbi made with White Mini broiler meat showed the best quality among the three chicken breeds.
