Abstract

본 연구에서는 여러 가지 품종별 통보리가루를 20% 첨가하여 보리 국수를 제조하고 제조된 국수의 품질특성과 <TEX>${\beta}$</TEX>-glucan 함량 및 항산화활성 변화를 조사하였다. 호화특성 중 호화개시온도와 최고점도는 보릿가루 첨가에 따라 증가하였고, 치반점도는 감소하였다. 통보리가루 첨가 국수의 L값은 밀가루 국수에 비해 낮았고 a값과 b값은 높았다. 조리시 흡수율은 통보리가루 첨가국수에서 밀가루 국수보다 낮게 나타났으며, swelling index는 메성보리는 높았고 찰성보리는 밀가루 국수와 비슷하였다. 보리국수의 조리 후 경도, 검성은 밀가루 국수에 비해 약간 낮았으며, 메성보리가 찰성보리보다 경도, 응집성, 검성이 높았고 메성 품종인 다한이 가장 밀가루 국수와 유사한 특성을 보였다. 보릿가루 첨가에 따라 국수의 <TEX>${\beta}$</TEX>-glucan 함량은 증가하였으며, 조리 후 <TEX>${\beta}$</TEX>-glucan 함량이 약간 증가하였고, 전분함량은 조리 후 감소하였다. 보리첨가 국수의 항산화활성은 밀가루 국수보다 높았고 조리 후 감소하였다. This study was conducted to investigate the effects of substituting whole barley flours on quality characteristics of noodles. Noodles were made with composite flour containing 20% whole barley flour of various hullless barley cultivars and the quality characteristics, <TEX>${\beta}$</TEX>-glucan content and antioxidant characteristics were investigated. In amylogram characteristics, the initial pasting temperature and peak viscosity were increased, and setback was decreased in complex flour. Noodles containing barley flour had low lightness, yellowness and high redness compare to wheat noodle. Water absorption of cooked noodles was lower than wheat noodle. The value of swelling index was high in noodles containing non-waxy barley flour and low in noodles containing waxy barley flour. Hardness and gumminess of noodles were lower than wheat noodle. Noodles containing non-waxy barley had higher hardness, cohesiveness and gumminess than noodles containing waxy barley flour. Dahan, non-waxy barley cultivar showed similar characteristics with the wheat noodle. <TEX>${\beta}$</TEX>-Glucan content and antioxidant activity were increased with adding barley flour. Cooked noodle had slightly high <TEX>${\beta}$</TEX>-glucan content, low starch content and low antioxidant activity compared to value of uncooked noodle.
