비트 분말 첨가 흰찰쌀보리 증편의 기능성 및 품질 특성

Abstract

This study is performed to examine the functional and quality characteristics of glutinous barley Jeung-pyun added with beet powder. Jeung-pyun is being prepared with concentration of 0, 2, 4, 6 and 8% (w/w) of the beet according to nonglutinous rice powder weight. The pH level of Jeung-pyun batters decrease along with fermentation time. However, the pH level of Jeung-pyun is higher than that of the Jeung-pyun batter. For hunter's color value of glutinous barley Jeung-pyun added with beet powder, the L (lightness) values decrease with increasing concentrations of beet powder, whereas a (redness) values increase (p<0.001). In the texture analysis, the hardness, chewiness and gumminess are significantly increased with the amount of glutinous barley Jeung-pyun with added beet powder. According to sensory evaluations, the appearance, color, flavor, taste, texture and overall quality are considered very good in the 4% of added beer powder in glutinous barley Jeung-pyun (p<0.001). The antioxidant activities of beet powder by DPPH free radical scavenging activity, ferric reducing antioxidant power and total phenolic contents are being recorded at <TEX>$259.52{\mu}{\ell}/mg$</TEX>, <TEX>$0.44{\pm}0.01$</TEX>, <TEX>$15.29{\pm}0.04mg$</TEX> GAE/g respectively. The antioxidant activities of glutinous barley Jeung-pyun added with beet powder increase with increasing concentrations of beet powder. These results suggest that beet powder are useful as functional food resources within antioxidant activities.
