Abstract
In this study, buckwheat four was classified by the order of extraction from the inmost layer to the outmost layer, and was designated as $B_1,\;B_2,\;B_3,$ and the mixed flour of $B_1,\;B_2,\;B_3$ (1:1:1) was named $B_0$. To improve the dried noodle-making properties, various levels of strong wheat flour and additives such as sodium alginate (SA) and xanthan gum(XG) were added to buckwheat. 1) The buckwheat $B_2$ and $B_3$ flours contained much higher amounts of crude ash, protein and fat than the $B_1$ flour. 2) Buckwheat $B_3$ flour demonstrated lower maxium viscosity value by amylograph than the $B_1$ flour, but it demonstrated 2 times higher maximum viscosity value than wheat flour. Buckwheat $B_1$ flour demonstrated 4-5 times higher maximum viscosity value than wheat flour. Addition of SA and XG increased the viscosity of the flour mixtures. 3) It was possible to make dried noodles from the composite flour of (buckwheat 40 %+wheat 60 %). The lesser the quantity of buckwheat flour was, the better the kneading property of mixed flour was. 4) SA and XG, which were added at the level of 1.0-1.5%, significantly improved dough making properties and the cooking quality of the noodles.
메밀을 제분하여 내층부터 외층까지 $B_1,B_2,B_3$ 및 $B_0$분$(B_1:B_2:B_3=1:1:1)$으로 나누고 이들에게 제면적성을 향시키기 위하여 강력밀가루를 혼합하고 여기에 결착성개량제인 sodium alginate (SA)와 xanthan gum(XG)를 첨가하여 전면을 제조할 때의 제면적성을 알아보았다. 1) 메밀분 $B_1$에서 $B_2,B_3$로 될 수록 조회분, 조단백, 조지방의 함량이 현저하게 높았다. 2) Amylograph에 의한 메밀분 $B_1$의 최고 점도는 밀가루에 비하여 $4{\sim}5$배 정도로 높으며, $B_3$은 $B_1$보다는 낮으나 역시 밀가루보다 2배이상 높다. 또한 SA와 XG는 원료분의 최고점도를 더 높여주었다. 3) <메밀분 40+강력밀가루60>수준부터 밀가루 혼합수준을 높여야 상온에서의 전면제조가 가능하였으며, 이들의 조리특성도 메밀분의 혼합수준이 낮아질수록 밀가루면에 접근하였다. 4) 메밀건면의 제조에서 XG, SA를 $1.0{\sim}1.5$% 수준으로 첨가하면 면대형성, 조리면의 제성질등 제면적성을 개선하였다.
