동결건조 들깻잎 분말을 첨가한 머핀의 품질특성

국문 초록 (Abstract)

기능성 소재로서의 들깻잎 분말의 이용가능성을 알아보기 위해 들깻잎 분말 0, 3, 6 및 9% 첨가한 머핀을 제조하여 품질 특성을 조사하였다. 머핀의 무게는 들깻잎 분말 첨가량이 증가할수록 감소하였고, 굽기손실률 및 높이는 증가하였다. 넓이는 윗넓이, 밑넓이 모두 들깻잎 분말 첨가에 따른 일정한 경향을 보이지 않았다. 머핀의 색도는 첨가량이 증가할수록 L, b값은 감소하였고, a값은 유의차가 나타나지 않았다. 물성 측정결과 경도와 탄력성은 들깻잎 분말 첨가량에 따라 유의차를 나타내지 않았으며, 응집성, 검성, 씹힘성은 들깻잎 분말 첨가에 따른 일정한 경향을 보이지 않았다. 항산화 활성 측정결과는 들깻잎 분말 첨가량이 증가할수록 증가하는 경향을 보였으며, 관능 측정 결과 동결건조 들깻잎분말 3∼6%(w/w)로 첨가할 시 개발가능성이 있는 것으로 나타났다.

This study investigated the quality of muffin prepared with various concentrations of freeze dried-perilla leaves (Perilla frutescens var. japonica HARA) powder. Muffin was prepared by addition of 0, 3, 6 and 9% powder to the flour of basic formulation. The weight of muffin decreased with increase in freeze dried-perilla leaves powder concentration, but no constant tendency in the bottom and upper dimensions by its addition was found. The height and baking loss rate of the muffin increased with increase in the powder concentration but with no significant differences. Lightness and yellowness of muffin decreased as the concentration of the powder increased, whereas no significant differences in the redness was found with increased powder concentration. The hardness of muffin increased, and springiness decreased with increase in the powder concentration, although not significant. The cohesiveness, gumminess and chewiness showed no consistent tendency by addition of the powder. The antioxidative activity measured by 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of muffin increased as the concentration of the powder increased. The muffin contained 0∼6% freeze dried-perilla leaves powder had acceptable sensory properties, such as color, taste, and overall acceptability. Results indicated that optimal concentration of freeze dried-perilla leaves powder into the muffin formula was 3∼6%(w/w).
