Abstract

Ramen flour formulation was optimized by applying a mixture experimental design. In the optimization, the overall palatability (OP) of cooked ramen and the rheological properties of selected dough were maximized or minimized. Blended ratios of the ingredients such as Dark Northern Spring (DNS), Hard Red Winter (HRW), and Soft White (SW) were designed on a simplex-lattice. Dough rheological properties were measured by Rapid Visco Analyser (RVA), Farinograph, and Extensograph, and the overall palatability by sensory evaluation. Several principal dough rheological properties such as RVA peak viscosity (PV), Farinograph development time (DT), and Extensograph resistance/extensibility after 45 min (R/E 45 min) were selected to influence the overall palatability by canonical correlation analysis (CCA). Goals of the optimization were given as OP maximized, PV maximized, DT minimized, and R/E at 45 min maximized. The optimization results were found to be DNS 33.3%, HRW 33.3%, and SW 33.3% with OP, 5.825; PV, 587.9 cP; DT, 3.1 min; R/E at 45 min, 2.339 BU/mm.

혼합물실험계획법(mixture experimental design)을 적용하여 라면 밀가루 혼합비를 최적화하였다. 밀가루 혼합비를 최적화하기 위하여 전체 기호도(overall palatability)의 최대화, 반죽 레올로지 특성의 특정 범위 유지를 최적화의 목적으로 설정하였다. 라면은 가장 보편적인 미국산 밀가루 중 강력분인 DNS, 중력분인 HRW, 박력분인 SW를 simplex-lattice 방식에 의해 혼합비를 달리하여 제조하였다. 각 시료는 Rapid Visco Analyser(RVA), 파리노그래프, 익스텐소그래프를 이용하여 반죽의 레올로지 특성치를 측정하였으며, 조리된 라면의 전체 기호도를 관능 검사 하였다. 정준상관분석(canonical correlation analysis)를 통하여 RVA의 최고점도(PV), 파리노그래프의 반죽형성시간(DT), 익스텐소그래프의 R/E 45 min을 주요 반죽 레올로지 특성치로 선발하였다. 최적화 목적으로 전체 기호도의 최대화와 최고점도(PV)(최대화), 반죽형성시간(DT)(최소화) 및 R/E45 min(최대화)를 지정하였다. 그 결과 최적화된 밀가루 혼합비는 DNS 33.3%, HRW 33.3% 및 SW 33.3% 이였으며, 이때 전체 기호도는 5.825, 최고점도(PV)는 587.9 cP, 반죽형성시간(DT)은 3.1 min, R/E 45 min는 2.339 BU/mm로 나타났다.
