콩가루의 대체수준이 만두피의 이화학적 특성 및 관능적 특성에 미치는 영향

Abstract

Purpose: This study examined the effects of wheat flour substitution with soybean flour on dumpling shells. Methods: Dumpling shells were prepared with 0, 5, 10 and 15% soybean flour. The physicochemical, textural and sensory characteristics were then investigated. The microstructure of the dumpling shell dough was examined by confocal laser scanning microscopy(CLSM). Results: The gluten contents decreased with increasing the level of soybean flour replacement. Small gabs and irregular distribution of the gluten proteins were visible in the CLSM micrographs. Color determination indicated that the soybean flour made the dumpling shell darker and more yellowish. The textural hardness and chewiness decreased with soybean flour addition. Soybean flour substitution in dumpling shell did not affect the overall acceptability. Conclusion: Soybean flour can replace up to 15% wheat flour without decreasing the overall acceptability.
