Abstract

In order to investigate the effects of pickle carrier on physico-chemical characteristics of seasoning chicken products, chicken were cured in seasoning containing 100 ppm germanium water, green tea, water soluble mineral and mixtures(100 ppm germanium water+green tea+water soluble mineral) after addition of 0.1% concentration to the weight of chicken. The determination of pH, salt and sugar contents were carried out, according to curing time. The salt content showed 1.11 %, 1.21 % in cured at 24 hours in control of breast and leg, irrespective of chicken parts, in which showed 19.94 brix, 18.89 brix in sugar content, respectively. These results mean that breast and leg meat added with natural extracts and functional water showed higher sugar content than that of control, in which revealed shortening of curing time by increasing penetrating velocity of salt and sugar content. Thus, salt and sugar content tended to be increased as the curing time of pickle carrier were extended in seasoning chicken after dipping in pickle containing water soluble mineral ions for 6 hours. The seasoning chicken treated with natural extracts and functional water showed a lower than that of control in hardness, irrespective of chicken parts. Overall, the seasoning chicken treated with natural extracts and functional water showed a low TBARS value and Log CFU/g, in which revealed antioxidative and antimicrobial activity. The sensory evaluations of seasoning chicken added with natural extracts and functional water containing water-soluble mineral ions were not significantly different(P<0.05). The glutamic acid among free amino acid contents showed a high in seasoning chicken treated with green tea, compared to control. This amino acid played a important role in taste of seasoning meat. The doneness appearance in seasoning chicken added with natural extracts and functional water containing water-soluble mineral ions tended to not be different, compared to those of control. These results revealed that seasoning chicken added with natural extracts and functional water containing water-soluble mineral ions would be attractive in fast food market on the basis of improvement of tenderness, shortening of curing time and uniformity of roasting appearance in seasoning chicken.

본 실험에서는 천연 추출물중 항산화성이 우수한 추출물을 선발하여 계육 양념육 제품을 개발하고, 둘째. 양념육의 침투속도를 높이기 위하여 수용성 미네랄 성분과 Ge-132를 이용하여 양념계육 제품에 대한 이화학적 특성을 검토하였다. 이상의 게르마늄, 녹차, 수용성 미네랄 및 녹차+게르마늄+수용성 미네랄 복합 첨가 양념 닭고기 제품의 이화학적 결과를 보면, pH는 염지전 가슴부분이 6.00~5.94, 다리부분이 6.55~6.38로 염지 기간 중 처리구간의 pH의 차이는 나타나지 않았으며, 닭고기 부위에 따른 차이는 가슴부분보다 다리부분이 조금 높게 나타났다. 염도와 당도는 염지기간 중 증가하는 경향이었으며, 염도의 경우 염지 24시간째 대조구의 가슴과 다리부분이 각각 1.11%, 1.21%를 나타내었다. 그러나 수용성 미네랄 첨가구 모두 저장 6시간과 12시간째 대조구의 염도보다도 높은 값을 나타내었다. 당도의 경우도 마찬가지로 대조구 24시간째 19.94 brix, 18.89 brix를 저장 6시간째 천연물과 기능수 첨가구 모두 가슴과 다리부분에서 높은 당도를 나타내었다. 가열조리 후 각 처리양념 닭고기제품의 경도 변화는 대조구에 비하여 모든 처리구가 부위에 관계없이 낮은 값을 나타내 었으며 특히, 녹차 첨가구는 가슴부분과 다리부분이 각각 122.59, 142.59kg/$cm^2$로 가장 낮은 값을 나타내었다. 항균성의 경우 대조구의 가슴부분 4.23CFU/g, 다리부분 4.24CFU/g에 비하여 가슴부분은 녹차 첨가구가 3.76CFU/g, 녹차+게르마늄+수용성 미네랄 복합첨 가구가 3.61CFU/g으로 낮은 값을 나타내었고, 다리부분은 녹차 첨가구가 3.49CFU/g, 녹차+게르마늄+수용성 미네랄 복합 첨가구가 3.55 CFU/g으로 낮은 값을 나타내었다. 지방산화도의 경우는 부위에 관계없이 대조구에 비하여 낮은 TBARS값을 나타내었고 특히, 녹차 첨가구가 가슴부분 0.43, 다리부분 0.47로 TBARS값이 낮게 나타났다. 다즙성, 연도 및 종합적인 기호도에서는 대조구에 비하여 녹차, 수용성 미네랄 및 녹차+게르마늄+수용성미네랄 복합 첨가구가 양념 닭고기제품의 다리와 가슴부분 모두에서 유의하게 높은 수치를 나타내었다. 대조구의 유리아미노산 함량 1462.7mg에 비하여 녹차첨가구의 유리아미노산 함량은 1661.46 mg으로 증가하였고, 고기의 추출물에서 맛과 풍미에 중요한 역할을 하는 아미노산인 glutamic acid의 함량이 대조구에 비하여 녹차 첨가구가 534.24mg으로 높은 값을 나타내었다.
