Abstract

Effects of isomaltooligosaccharides on the characteristics of yackwa were investigated. Yackwa was prepared by replacing honey with 0, 25, 50% isomoltooligosaccharide. Isomaltooligosaccharide decreased reducing sugar contents and increased crude fat contents of yackwa. The exterior color of yackwa prepared with isomoltooligosaccharide showed lighter, less reddish and yellowish. Addition of isomaltooligosaccharides made yackwa lighter, rougher, more brittle and softer as perceived by panels. Yackwa prepared by replacing honey with 25% isomaltooligosaccharide showed good acceptability. The acceptability was significantly correlated with hardness, aroma and greasiness. The textural characteristics including hardness, cohesiveness and gumminess were decreased by replacing honey with isomaltooligosaccharide.

꿀의 25%, 50%를 이소말토올리고당(IMO)으로 대체한 약과를 제조하여 IMO가 약과에 질에 미치는 영향을 검토하였다. 꿀만을 사용한 대조군 약과(Y-0), 꿀의 25%를 IMO로 대체한 약과(Y-1), 꿀의 50%를 IMO로 대체한 약과(Y-2)를 제조하여 세 종류의 약과를 시료로 사용하였다. IMO를 사용한 약과는 Y-0에 비해 환원당 함량은 감소하였고, 지방함량은 증가하였다. 약과 표면의 색은 L, a, b값이 모두 약과간에 유의적 차이를 보였다(p<0.05). IMO를 사용한 약과는 대조군 약과에 비해 명도는 높아졌고 적색도와 황색도는 낮아졌다. 약과의 관능적 특성을 검토한 결과 IMO를 사용한 약과는 Y-0에 비해 색이 엷으며 균열이 많고, 잘 부서지며 견고성이 낮다고 평가되었다(p<0.05). 기호도는 꿀의 25%를 IMO로 대체한 약과인 Y-1이 가장 높게 평가되었으며, 견고성 및 냄새와 정의 상관관계(p<0.05)를 느끼한 맛과는 부의 상관관계(p<0.05)를 나타내었다. 텍스쳐 특성을 검토한 결과, IMO를 사용한 약과는 꿀만을 사용한 약과에 비해 견고성, 응집성, 검성이 낮아졌다(p<0.05).
