Abstract

The purpose of this study was to examine the physico-chemical and sensory characteristics of Kakdugi made with mashed red pepper. With regard to the pH of the Kakdugi, those of the juice from Kakdugi with red pepper powder and of the liquid with mashed red pepper were the highest and lowest immediately after preparation, respectively, but thereafter both slightly decreased, but were similar after the fifth week. Generally, the total acidity of Kakdugi liquid was the higher than that of Kakdugi juice. With regard to the L value, that of the Kakdugi juice was higher than that of Kakdugi liquid and that of Kakdugi with mashed red pepper washigher than that of Kakdugi with red pepper powder. From the third week, the 'L' values of all samples generally decreased. The 'a' value of the Kakdugi liquid with mashed red pepper during fermentation was highest During early fermentation, the juice of Kakdugi with red pepper powder showed a higher value than that of Kakdugi with mashed red pepper, but conversely, from the second week that of Kakdugi with mashed red pepper was higher than that of Kakdugi with red pepper powder. The 'b' value of the juice from Kakdugi with red pepper powder was highest until the second week, but from the third week that of Kakdugi with mashed red pepper was highest. With respect to the organic acids contents, those of citric, quinic and malic acids decreased, but those of lactic and acetic acids increased during fermentation progression. In addition, the citric, lacticand malic acids contents of the Kakdugi with mashed red pepper werethe highest, whereas that of quinic acid of the Kakdugi with red pepper powder was the highest. From the forth week, the acetic acid content of the Kakdugi with mashed red pepper was further increased. As a result of the sensory test, Kakdugi with mashed red pepper showed significantly higher values with regard to redness and fresh flavor, but in overall acceptability in the QDA, appearance and taste in the acceptance test. Therefore, our results indicate that mashed red pepper particularly increased the 'a' value and organic acid contents of Kakdugi compared to those of red pepper powder, leading to an increased overall acceptability.

냉동마쇄고추를 첨가한 깍두기의 4$^{\circ}C$ 저장기간중의 이화학적 성분 변화 및 관능적 특성을 알아본 결과는 다음과 같다. pH는 담금 직후 고춧가루를 첨가한 깍두기 마쇄액이 가장 높았고 마쇄 고추를 첨가한 깍두기액이 가장 낮았으며 숙성이 진행될수록 차이가 감소하여 숙성 5주째에는 거의 비슷한 값을 나타냈다. 총산 함량은 전반적으로 마쇄고추 첨가구가 고춧가루 첨가구보다 높게 나타났다. L값은 깍두기 마쇄액이 깍두기액보다 더 높은 값을 나타냈고 마쇄고추를 사용하여 담근 것이 고춧가루를 사용한 것보다 높게 나왔으며 전반적으로 숙성 3주부터는 모든 시료에서 L값의 감소를 보였다. a값은 마쇄고추를 사용한 깍두기액이 전 숙성기간동안 가장 높은 값을 보였고 마쇄액에서는 숙성초기에 고춧가루 첨가구가 마쇄고추 첨가구보다 높게 나왔으나 숙성 2주가 지나면서 반대로 마쇄 고추를 사용한 것이 더 높은 값을 나타냈다. b값은 깍두기 마쇄액에서 숙성 2주까지는 고춧가루 첨가구가 가장 높았고 3주째부터는 마쇄고추 첨가구가 고춧가루 첨가구보다 약간 높은 값을 보이다가 숙성 2주째에는 서로 일치하였고 숙성 3주째부터는 다시 마쇄고추 첨가구의 값이 더 상승하는 경향을 보였다. 유기산 함량 변화에서는 숙성이 진행됨에 따라 citric, quinic, malic acid는 감소 하였고 lactic과 acetic acid는 증가하였다. 또한 citric, lactic 및 malic acid는 마쇄고추 첨가구가, quinic acid는 고춧가루 첨가구가 더 높은 함량을 보였으며 acetic acid는 숙성 후반기인 4주째부터 마쇄고추 첨가구에서 더 증가하는 경향을 보였다. 관능검사에서는 QDA결과 적색도 및 상큼한 맛에서, 소비자 기호도 검사에서는 종합적인 기호도, 외관 및 맛에서 마쇄고추 첨가구가 고춧가루 첨가구보다 유의적으로 높은 값을 보였고 마쇄고추 품종인 칠보, 포청천, 부촌 시료간에는 유의적인 차이를 보이지 않았다. 따라서 깍두기에 마쇄고추를 사용하면 고춧가루를 사용하는 것보다 특히 적색도와 유기산 함량을 증가시켜 깍두기의 기호도에 더 좋은 영향을 줄 수 있음을 알 수 있었다.
