  • Effects of double packaging (combinational use of aerobic and vacuum conditions) and antioxidants on physicochemical properties in irradiated restructured chicken rolls were determined. Chicken breast treated with antioxidants (none, sesamol+a-tocopherol) was used to process restructured chicken breast rolls. The sliced rolls were vacuum, aerobic, or double packaged (vacuum for 7 d then aerobic for 3 d) and electron beam irradiated at 2.5 kGy. Color, 2-thiobarbituric acid reactive substances (TBARS), oxidation reduction potentials (ORP), and volatile profiles of the samples were determined at 0 and 10 d. Irradiation made restructured chicken rolls redder (p<0.05), and the increased redness was more distinct in irradiated vacuum-packaged than irradiated aerobic or double packaged meats. TBARS values of antioxidant-treated double packaged rolls were lower than even nonirradiated vacuum-packaged meat, and those were distinct at 10 d (p<0.05). ORP and lipid oxidation values were lower in irradiated vacuum and double packaged samples than those in irradiated aerobic packaged ones at 0 d (p<0.05). Irradiation of restructured chicken rolls increased the amount of total volatiles. Considerable amounts of off-odor volatiles were reduced or not detected by double packaging and antioxidant treatment at 10 d. Therefore, the combined use of antioxidants and double packaging would be useful to reduce redness and control the oxidative quality changes of irradiated restructured chicken rolls

  • 닭고기 가슴육에 대하여 가스를 넣지 않는 대조구와 $CO_2$$N_2$를 혼합 처리한 가스치환포장구로 나누어 냉장저장($4^{\circ}C$)한 결과 저장 1일에 80% $CO_2$의 첨가구에서 pH의 유의적인 감소를 나타내었다(p<0.05). 가슴육의 명도($L^*$)는 모든 저장 기간 동안 $CO_2$의 농도가 60% 이상일 때 대조구에 비해 유의적으로 증가하였으며 적색도($a^*$)와 황색도($b^*$)는 가스처리에 따른 유의적인 차이는 보이지 않았다. 단백질변성도(VBN)와 지방산패도(TBARS)는 대조구에 비하여 60% 이상의 $CO_2$ 처리구에서 감소를 보였다(p<0.05). 닭가슴육의 총균수는 저장 1일에는 가스 처리군간의 유의적인 차이를 보이지 않았으나 저장 3일과 6일에는 40% $CO_2$ 처리군에서 유의적인 감소를 나타내었다(p<0.05). 그러나 $CO_2$를 60-80%으로 고농도 처리 포장 하여 냉장 저장 시 포장 용기가 찌그러지는 현상이 발생하여 상품성의 저하를 초래하였다. 따라서 상기의 성적을 고려할 때 닭가슴살을 $CO_2$, $N_2$를 이용한 가스치환하여 포장 시에는 $CO_2$는 40% 이하로 $N_2$ 는 60%로 유지하는 것이 적절한 것으로 판단된다.

  • This experiment was carried out to find out the effects of packing methods on shelf-life and hy-giene of breast and thigh meats in chicken. The carcass weights were about 1.6 kg per bird, and chilled by air spray method. The breast and thigh meats were packed by either vacuum or atmosphere packing methods. Samples were analyzed at 1, 4, 8, 12 and 16 wk after quick freezing at -45˚C for 35 min. Regardless of packing method. The thiobarbituric acid(TBA) values of thigh meats after 1 wk of storage were higher than those of breast meats. The TBA values of both treatments were increased as storage period extended. In addition, the TBA values of vacuum packed meats were lower than those of atmosphere packed meats. The VBN(volatile basic nitrogen) values, regardless of packing method, at 1 wk of storage were higher than those of breast meats. The VBN contents of breast and thigh meats after 16 wk of storage increased markedly, but failed to show significant difference between the two packaging methods. Total plate counts of breast and thigh meats were increased gradually as storage period extended, and the total plate count of breast meat was higher than that of thigh meat. The coliform bacteria were not detected until 16 wk after storage.

  • The consumption of poultry meat (chicken and turkey) grew the most during the past few decades due to several contributing factors such as low price, product research and development, favorable meat characteristics, responsive to consumer needs, vertical integration and industry consolidation, new processing equipments and technology, and aggressive marketing. The major processing technologies developed and used in chicken processing include forming/restructuring, tumbling, curing, smoking, massaging, injection, marination, emulsifying, breading, battering, shredding, dicing, and individual quick freezing. These processing technologies were applied to various parts of chicken including whole carcass. Product developments using breast, thigh, and mechanically separated chicken meat greatly increased the utilization of poultry meat. Chicken breast became the symbol of healthy food, which made chicken meat as the most frequent menu items in restaurants. However, the use of and product development for dark meat, which includes thigh, drum, and chicken wings were rather limited due to comparatively high fat content in dark meat. Majority of chicken are currently sold as further processed ready-to-cook or ready-to-eat forms. Major quality issues in chicken meat include pink color problems in uncured cooked breast, lipid oxidation and off-flavor, tenderness PSE breast, and food safety. Research and development to ensure the safety and quality of raw and cooked chicken meat using new processing technologies will be the major issues in the future as they are now. Especially, the application of irradiation in raw and cooked chicken meat products will be increased dramatically within next 5 years. The market share of ready-to-eat cooked meat products will be increased. More portion controlled finished products, dark meat products, and organic and ethnic products with various packaging approaches will also be introduced.

  • Effects of vacuum packaging and modified atmosphere packaging (MAP) on shelf life of selenium-supplemented chicken meat during refrigerated storage were examined. Body weight and feed efficiency were unaffected by dietary selenium level. Dietary treatments and packaging methods had no significant effects on level of microbial growth, lightness, and metmyoglobin content. MAP decreased purge loss (10.9-34.5%) and lipid oxidation (15.2-15.9%) more efficiently than vacuum packaging. Broiler chicks supplemented with ${\alpha}$-tocopherol or ${\alpha}$-tocopherol + selenium had similar TBA values. Dietary supplementation of 4 and 8 ppm selenium reduced lipid oxidation, and this effect was less significant in MAP breast meat.

  • 닭가슴살의 품질변화를 실시간으로 모니터링하기 위하여 pH 지시약, AA, 다공성 기재인 $Tyvek^{(R)}$을 이용하여 신선도 인디케이터를 제조하였다. 닭가슴살의 대표적인 지표물질은 TVBN과 $CO_2$이며, 이는 저장기간에 따라 미생물의 증식과 단백질 분해를 통해 증가한다. 닭가슴살 저장실험 결과 미생물 수로 판단한 초기부패단계의 $CO_2$ 농도와 TVBN 발생량은 각각 19%와 23 mg%로 확인되었다. 지표물질 발생량 데이터를 토대로 BCG 및 AA의 농도별 인디케이터를 제조하여 인디케이터 색변화 시뮬레이션을 실시하였다. 그 결과, AA의 함량에 따른 인디케이터의 색변화구간 조절 가능성이 확인되었으며, 제조한 인디케이터 중 "G0.12_A0.5"의 인디케이터가 닭가슴살 초기 부패판정 농도인 TMA 20 mg%에서 육안으로 확인할 수 있는 뚜렷한 색변화를 보였다. 시뮬레이션을 통해 선정된 최적 조성의 인디케이터를 닭가슴살 포장내부에 부착하였으며, $4^{\circ}C$$10^{\circ}C$에서 8일동안 닭가슴살의 이화학적 변화와 그에 따른 인디케이터의 색변화를 관찰하였다. 그 결과, TCD 값을 통해 판단된 인디케이터의 색변화 발생일이 각 온도별 닭가슴살 초기부패판정일과 잘 부합하였으며, 이를 통해 시뮬레이션의 신뢰성을 확보할 수 있는 것으로 확인되었다. 본 연구 결과는 저장 중 닭가슴살의 품질변화를 제조한 인디케이터의 포장 내 부착을 통하여 감지하고 실시간 신선도 판단이 가능할 것으로 사료된다.

  • This study was performed to examine the possibility of water extracts for several medicinal plants, such as Amomum tsao-ko, Alpinia oxyphylla, and Citrus unshiu, as an active packaging ingredient for prevention of lipid oxidation. Chicken breast meats were packed with medicinal plant extracts incorporated carrageenan based films and their physico-chemical and microbial properties during storage at $5^{\circ}C$ were investigated. In chicken meat samples packed with A. tsao-ko (TF) or A. oxyphylla (OF) extract incorporated carrageenan based films, pH value, thiobarbituric acid reactive substances (TBARS), and the population of total microbes were significantly lower than those of the negative control (film of no extract was incorporated, CF) after 5 d of storage (p<0.05). Especially, TBARS value of TF ($0.12{\pm}0.01$ mg malonaldehyde/kg meat) was significantly lower than chicken meat samples packed with positive control (ascorbic acid incorporated film, AF, $0.16{\pm}0.01$ mg malonaldehyde/kg meat) at 3 d of storage, and it means TF has enough antioxidative activity to prevent the lipid oxidation of chicken meat. However, there was no consistent effect on VBN values of chicken meats packed with medicinal plant extracts incorporated films during storage. Based on the obtained results, it is considered that A. tsao-ko extract has potential for being used as a natural antioxidant ingredient in active packaging areas.

  • Chicken breast meat was injected with calcium chloride alone and in combination with lactic acid (0.01% and 0.002%, respectively). The inhibitory effects of the treatments on microbial growth were determined in the injected chicken breast meat stored at $4^{\circ}C$ under aerobic packaging condition for 0, 3, and 7 d. Calcium chloride combined with 0.002% and 0.01% lactic acid reduced microbial counts by 0.14 and 1.08 Log CFU/g, respectively, however, calcium chloride alone was unable to inhibit microbial growth. Calcium chloride combined with 0.01% lactic acid was the most effective antimicrobial treatment and resulted in the highest initial redness value. Calcium chloride alone and combined with lactic acid suppressed changes in pH and the Hunter color values during storage. However, injection of calcium chloride and lactic acid had adverse effects on lipid oxidation and sensory characteristics. The higher TBARS values were observed in samples treated with calcium chloride and lactic acid when compared to control over the storage period. Addition of calcium chloride and lactic acid resulted in lower sensory scores for parameters tested, except odor and color, compared to control samples. Therefore, the formulation should be improved in order to overcome such defects prior to industrial application.

  • 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.
