초록

The purpose of this study was to determine the optimization mixing ratio of wheat sprout powder (WSP) and hemicellulase for the preparation of white pan bread. Using a response surface methodology, independent variables were WSP and hemicellulase. Dependent variables were physicochemical properties, antioxidant properties and sensory evaluation. Water binding capacity of dough increased with increasing WSP. Color value showed positive correlations with WSP. L value decreased and a, b values increased as WSP increased. The adjusted determination coefficient of texture analysis was calculated to be 0.7230～0.9446 having the p-value less than 0.1. Specific volume of bread showed a positive correlation with hemicellulase and a negative correlation with WSP. DPPH radical scavenging activity and total polyphenol were represented by a linear model and showed positive correlations with WSP.
Sensory evaluation were represented by a quadratic model. In conclusion, the optimal formulation for WSP added bread, as assessed by numerical and graphical optimization methods, was WSP 2.36%, hemicellulase 0.069% per wheat flour 100 g. The above results indicate that WSP can be used as health-oriented material in the bread industry. This is also expected to meet demands of consumers who are in the pursuit of healthy food.
