Abstract

We investigated quality changes in dumpling shells prepared using various concentrations of Enteromorpha intestinalis powder(EIP). Dumpling shells were prepared by addition of 0%, 3%, 5%, 7%, and 9%(all w/w) EIP to the flour used in the basic formulation. The gelatinization temperature of the EIP-wheat flour composite increased whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 min, and maximum viscosity, all fell with increasing EIP content, as measured by amylography. In addition, the Hunter's color L, a, and b values decreased significantly with increasing amounts of EIP. All of cooked weight, cooked volume, and water absorption of dumpling shells prepared with EIP were significantly greater than control values. In terms of textural characteristics, addition of EIP increased hardness, springiness, and chewiness, but decreased adhesiveness and cohesiveness. Sensory evaluation showed that dumpling shells prepared with 5% (w/w) EIP were preferred.

다양한 생리활성 기능을 가진 파래 분말을 첨가하여 제조한 만두피의 품질특성을 측정한 결과는 다음과 같다. 호화개시온도는 파래 분말의 첨가량이 증가될수록 점진적으로 증가하는 경향을 보였다. $95^{\circ}C$에서 점도, $95^{\circ}C$에서 15분간 유지한 후의 점도 및 최고점도는 파래 분말의 첨가량이 증가함에 따라 감소하는 것으로 나타났다. 만두피의 색도는 파래 분말 첨가량이 증가할수록 명도(L값), 적색도(a값) 및 황색도(b값)는 대조군이 가장 높게 나타났으며, 각 시료간에 유의하게 감소하였다. 조리특성에서 파래 분말을 첨가한 만두피는 대조군에 비해서 중량의 증가나 부피의 증가, 수분흡수율 등이 모두 유의적으로 높게 나타났다. 만두피의 조직감은 파래 분말 첨가량이 증가될수록 경도, 탄력성 및 씹힘성은 높아졌으며, 부착성과 응집성은 감소하였다. 만두피의 관능검사 결과 전체적인 기호도는 파래 분말 5% 첨가군이 가장 좋은 것으로 나타났다. 이상의 결과를 종합하여 보면 기능성 만두피 제품 개발을 위해 파래 분말을 첨가할 경우 밀가루 대비 5% 정도 첨가할 때 기호 특성에서 적당한 것으로 사료되며, 기능적인 측면과 영양적인 측면에서 도움을 줄 수 있는 만두피로 사용될 수 있을 것으로 여겨진다.
