Abstract

Several soft white spring and winter wheat cultivars were evaluated by analyzing physicochemical properties such as Single Kernel Characterization System (SKCS), milling properties, Rapid Visco-Analyzer (RVA), mixograph pattern, and sugar-snap cookie-making potentialities. Results of SKCS revealed kernel hardness had a positive correlation coefficient with test weight $(r=0.497^{*})$ and near-infrared reflectance (NIR) hardness $(r=0.495^{*})$. SKCS kernel weight had a significantly high correlation of $r=0.942^{**}$ with SKCS kernel size. The test weight had significantly high correlations with straight-grade flour yield $(r=0.720^{**})$, break flour yield $(r=0.490^{*})$, flour ash content $(r=-0.781^{**})$, and milling score $(r=0.838^{**})$. The average RVA peak viscosity of the soft white winter wheat was higher (195.1 unit) than the soft white winter wheat varieties (135.7 unit). A correlation was found between RVA peak viscosity and swelling volume. Significant correlation coefficients were obtained among cookie properties, milling properties, protein content, and mixograph absorption. The cookie top grain score had a correlation coefficient of $r=0.447^{*}$ with swelling volume.

연질밀(Triticum aestivum L. em Thell.)로서 soft white spring(SWS) 밀과 soft white winter(SWW) 각각 10품종(또는 계통)을 공시재료로하여 종실의 이화학적 품질특성, 제분특 성, 호화특성, mixograph특성 및 sugar-snap cookie의 제조특성을 측정하고 이들 특성간의 상관관계를 구명하고자 일연의 실험을 실시한 바 그 결과를 보고한다. Single Kernel Characterization System(SKCS) kernel hard-ness와 용적중, near-infrared reflectance(NIR) hardness와는 각각 $r=0.947^{*},\;r=0.495^{*}$의 정의 상관이 있었으며 SKCS weight와 SKCS size와는 $r=0.942^{**}$의 고도의 정의 상관이 있었다. 용적중과 straight-grade flour yield, break flour yield, 밀가루 회분 함량 및 제분평점과는 각각 $r=0.720^{**},\;r=0.490^{*},\;r=-0.781^{**}$$r=0.838^{**}$ 의 고도의 정 또는 부의 상관이 있었다. 종실의 단백질 함량과 straight-grade flour yield, break flour yield 밀가루 회분 함량 및 제분평점은 각 각 $r=-0.786^{**},\;r=-0.765^{**},\;r=-0.889^{**}$$r=-0.938^{**}$로 서 고도의 정 또는 부의 상관이 있었으며 이와 같은 현상은 밀가루 단백질 함량에서 동일한 결과를 보였다. Mixograph 흡수을과 제분특성과는 고도의 정 또는 부의 상관이 있었으며, 특히 종실의 단백질 함량과는 $r=0.938^{**}$, 밀가루의 단백질 함량과는 $r=0.901^{**}$의 고도의 정의 상관이 있었다. Cookie 직경과 cookie top grain score는 $r=0.946^{**}$의 고도의 정의 상관이 있었다. Cookie특성과 제분특성, 단백질 함량 및 mixograph 흡수율과는 고도의 정 또는 부의 상관이 있었으나 전분특성과는 단지 swelling volume과 cookie top grain score 만이 $r=0.447^{*}$의 정의 상관이 있었다.
