Abstract

This study was conducted to promote the utilization of fish paste with added lotus leaf powder as a food. The tested concentrations of lotus leaf powder were 0, 0.5, 1, 1.5, and 2%. All the samples of fish paste with added lotus leaf powder had 37% water content. For the Hunter color values, the L, a and b values of the fish paste decreased with increasing concentrations of lotus leaf powder. And the folding test presented a good score(AA). In the texture meter test, the gumminess, and brittleness decreased according to increasing concentrations of lotus leaf powder. However, the hardness, cohesiveness, and springiness of the fish paste were not significantly changed by the addition of lotus leaf powder. In the sensory evaluation, the lotus leaf flavor, hardness, and adhesiveness increased as the concentrations of lotus leaf powder increased. The fish paste with 0.5% lotus leaf powder(0.5 LP) showed the highest acceptance scores in terms of pleasant taste and springiness. The fish paste with 0.5% lotus leaf powder(0.5 LP) also showed the highest acceptance scores for appearance, flavor, taste, texture, and overall quality. Therefore, the results suggest that lotus leaf powder can be applied to fish paste to increase its quality and functionality.

연잎 분말을 0, 0.5, 1, 1.5, 2%를 함유한 어묵을 제조하여 수분함량, 색도와 절곡검사, 기계적 texture, 관능검사, 기호도 검사 등의 품질특성을 조사하였다. 연잎 분말을 첨가한 연잎어묵의 수분함량은 모든 시료가 37%대의 수분을 함유하고 있어 고른 분포를 띠었다. 색도 변화에서 L, a, b값은 연잎 분말의 첨가량이 증가할수록 감소하였다. 어묵의 유연성을 나타내는 절곡 검사에서는 모든 시료에서 AA로 측정되어 연잎 분말의 첨가에 관계없이 우수한 것으로 나타났다. 연잎 분말을 첨가한 연잎어묵의 기계적 texture 특성에서는 경도, 응집성, 탄력성에서는 유의한 차가 인정되지 않았으나, 껌성과 파쇄성은 연잎 분말 첨가량이 증가할수록 감소하였다. 어묵의 관능검사에서는 연잎의 향미, 경도, 부착성은 연잎 분말의 첨가량이 증가할수록 높게 나타났으나, 구수한 맛과 탄력성은 0.5 LP군이, 씹힘성은 1 LP군이 가장 높게 평가되었다. 어묵의 기호도 검사에서는 0.5 LP군이 외관의 기호도, 향미의 기호도, 맛의 기호도, 질감의 기호도, 전반적인 기호도 등의 모든 항목에서 가장 높은 평가를 받았다. 따라서 연잎을 첨가한 건강기능성 연잎 어묵의 가공 적성에 적절한 연잎의 첨가량은 0.5%가 적당하다고 사료되며 연잎을 함유한 고품질의 어묵의 제조 가능성을 확인하였다.
