Abstract

This study was conducted to evaluate quality characteristics of noodles containing barley flour and ${\beta}$-glucan enriched fraction. Compared to 100% wheat flour, composite flours containing barley flour and ${\beta}$-glucan enriched fraction decreased initial pasting temperature and increased maximum peak viscosity. The noodles containing ${\beta}$-glucan enriched fraction exhibited somewhat darker color and lower values in cooked weight, volume, moisture content, and cooking loss. From the textural properties measured by texture analyzer, the noodles with 30% barley flour and ${\beta}$-glucan enriched fraction were similar to 100% wheat noodle in springiness value and significantly higher in gumminess, hardness, and chewiness. The results of sensory evaluation indicated that barley flour or ${\beta}$-glucan enriched fraction at levels up to 30% could be substituted for wheat flour without seriously depressing noodle quality. Cooking of raw noodle with ${\beta}$-glucan enrichment slightly increased total, insoluble, and soluble ${\beta}$-glucan content.

생리적 활성이 큰 보리 ${\beta}$-glucan 을 효율적으로 활용하기 위한 방안으로 보리가루와 보리 ${\beta}$-glucan 강화분을 30% 수준으로 첨가하여 제조한 고식이섬유 국수의 품질 특성에 관하여 조사하였다. 보리가루와 보리 ${\beta}$-glucan 강화분을 첨가한 복합분은 중력분에 비해 호화개시온도가 낮았고 최고점도가 약간 높았으며 set back은 감소하여 노화속도가 느릴 것으로 해석되었다. 보리가루와 ${\beta}$-glucan 강화분을 첨가한 국수의 L값과 b값은 약간 낮았으며 조리했을 때 L, a, b값이 모두 감소하는 경향을 보였다. 보리 ${\beta}$-glucan 강화분을 첨가한 국수는 조리시의 체적, 중량, 함수율, 고형분 용출량이 대조구 보다 낮게 나타났다. 보리 ${\beta}$-glucan 강화분을 첨가한 국수의 조리후 텍스쳐에서 탄성은 대조구보다 떨어지나 검성, 견고성, 씹힘성은 더 높았으며 관능평가에서 대조구보다 다소 떨어지는 것으로 나타났다. 보리 ${\beta}$-glucan 강화 국수는 조리후 총, 불용성, 수용성 ${\beta}$-glucan의 함량이 약간 증가하였다.
