나문재 가루를 첨가한 식빵의 품질특성에 관한 연구

Abstract

This study examined the quality characteristics of bread enriched with Suaeda asparagoides powder, including antioxidative activity, at concentrations of 0%, 1%, 2%, 3%, and 4%. Analysis of Suaeda asparagoides powder revealed a moisture content of 5.34%, ash content of 21.03%, protein content of 32.08%, fat content of 5.12%, and a DPPH-free radical scavenging ability of 90.24%. The moisture content of the bread decreased with an increase in Suaeda asparagoides powder, although the difference was not significant. Conversely, the pH of the bread increased with higher concentrations of Suaeda asparagoides powder. The addition of Suaeda asparagoides powder led to an increase in weight, while the volume, cost, and baking loss rate decreased with higher concentrations. Hardness increased with greater amounts of Suaeda asparagoides powder, whereas springiness remained unchanged between the control group and the group with added Suaeda asparagoides powder. Sensory evaluation revealed that bread with 2% Suaeda asparagoides powder received the highest scores for color, flavor, taste, and overall preference. These results suggest that 2% is the optimal concentration of Suaeda asparagoides powder for enhancing the sensory quality and functional benefits of the bread.
