Abstract

Tarak is our own traditional fermented milk, which is made from lactic acid fermentation by using makgeolli as inoculum for milk or fermented by using Tarak that had already made. we made our own traditional fermented milk and Tarak Pudding by the traditional fermented milk, and then, we investigated the quality characteristics of Tarak Pudding on the addition rates of Tarak. As a result, the more the amount of Tarak, the more the contents of crude protein, crude fat and crude ash of Tarak Pudding according to the percentage of addition of Tarak meaningfully, except for its moisture content (p<0.05). While the pH decreased with more Tarak, the acidity significantly increased. In the case of sugar content, TP 1, 2, and 3 were higher than the control group, and TP 4 showed the higher sugar content(p<0.05). As the result of measurement of chromaticity of Tarak Pudding, the L value of the control group was 38.80. However, it increased with more addition of Tarak, while a value decreased. For the b value, it significantly increased with more Tarak. In the measure of texture, there were significant differences between the control group and the samples in hardness, springiness, cohesiveness, chewiness, and adhesiveness (p<0.05). The sensory evaluation result showed that there were meaningful differences among the samples in their appearance, taste, flavor, texture and overall acceptance. However, due to distinctive sour and odor of Tarak, TP 3 (75% addition) than TP 4 (100% addition) was considered to be desirable.

타락은 우유에 막걸리를 접종원으로 사용하거나 또는 미리 제조된 타락을 접종원으로 이용하여 젖산발효 시킨 우리 고유의 전통발효유이다. 이에 본 연구에서는 전통 타락을 제조하고, 타락의 첨가 비율에 따른 타락푸딩의 품질특성을 알아보고자 한다. 타락의 첨가비율에 따라 제조한 타락푸딩의 수분, 조단백질, 조지방, 조회분 함량의 분석결과 수분의 함량을 제외한 조단백질, 조지방, 조회분의 함량이 타락의 첨가량이 증가할수록 유의적으로 높아지는 경향을 나타내었다(p<0.05). pH의 경우 타락의 첨가량이 많을수록 저하하였고, 산도의 경우에는 pH와 반대로 타락의 첨가가 증가할수록 유의적으로 높아졌다. 당도의 경우 대조군에 비해 TP 1, 2, 3가 더 높았고 이들 보다 TP 4는 가장 높은 당도로 유의차를 보여줬다(p<0.05). 타락푸딩의 색도 측정 결과 L 값의 경우 대조군의 측정치가 38.80이였는데, 타락 첨가량이 증가할수록 타락푸딩의 L값이 증가하였고, a 값은 감소, b 값의 경우에는 유의적으로 증가하는 것으로 나타났다. 텍스쳐 측정 시 fracturability를 제외한 모든 항목에서 대조군에 비해 타락 첨가군이 hardness, springiness와 cohesiveness, chewiness, adhesiveness에서 시료 간 유의적인 차이가 있었다(p<0.05). 관능검사 결과 대조군에 비해 타락 첨가군인 TP 2, TP 3, TP 4가 맛, 향, 전반적인 기호도에서 높게 평가되었고, 이들 시료간의 통계적인 유의적 차는 없었다. 수치적 결과로 맛은 TP 4가 가장 높았고, 외형과 조직감은 TP 2가 높게 평가되었으나 풍미와 전반적인 기호도에서 TP 3가 가장 높았다. 이는 타락 특유의 신맛과 향으로 인해 푸딩 제조 시 타락 100% 첨가 TP 4보다 75% 첨가 TP 3가 바람직한 것으로 생각된다.
