This study examined the effects of Boehmerianivea powder on the functional and sensory characteristics of dumpling shell. Various dumpling shell samples were prepared with wheat flour containing different amounts of Boehmerianivea powder. The instrumental characteristics were examined and sensory evaluations were performed. According to the amylograph data, the composite Boehmerianivea powder-wheat flour samples had increased gelatinization temperatures with increasing Boehmerianivea powder content; whereas the initial viscosity at 95 ℃ viscosity at 95 ℃ after 15 minutes, and the maximum viscosity were reduced. The L, a and b Hunter's color values decreased with increasing Boehmerianivea powder content. In addition to the cooked weight, the cooked volume and turbidity of dumpling shell increased with increasing level of Boehmerianivea powder. In terms of the textural characteristics, the addition of Boehmerianivea powder increased the chewiness, smoothness and adhesiveness. The DPPH free radical scavenging activity increased significantly with increasing content of Boehmerianivea powder (p<0.05). Finally, the results of the sensory properties indicated that 5% Boehmerianivea powder had the highest scores. These results suggest that Boehmerianivea powder can be applied to dumpling shells to achieve high quality and functionality.
