초록

찰흑미(상해항혈나)에서 열수가용성 물질과 열수불용성 물질을 분리하여 그 전분의 겔 크로마토그래피 용출양상을 조사하였다. 열수가용성 물질은 찰흑미 전분이 16.6%,신선찰벼 전분이 13.4%였으며, 열수가용성 물질의 Sepharose CL-2B에 의한 용출양상은 두 시료 모두 void volume 부근에서 대부분 용출되었고, 열수가용성 물질에 대한 요오드복합체의 최대흡수파장은 신선찰벼 전분과 찰흑미 전분이 각각 522 nm와 520 nm로 생 전분에서의 요오드반응과 비교하여 약간의 이동이 있었다. 열수불용성 물질의 Sepharose CL-2B에 의한 용출양상은 열수가용성 물질의 용출양상과 서로 비슷하였으며 요오드복합체와의 최대흡수파장은 열수가용성 물질보다 낮았다.

Some structural characteristics of hot-water soluble and insoluble starches (waxy black rice starch) were investigated. The hot-water soluble material content of waxy black rice starch was higher (16.6%) than that (13.4%) of Shinsunchalbyeo starch heated at 98$^{\circ}C$ for 8 min. The Amax and absorbance at 625 nm for hot-water soluble and insoluble material of waxy black rice starch were lower than those of Shinsunchalbyeo. Elution patterns of hot water soluble and insoluble materials by gel permeation chromatography (Sepharose CL-2B) were similar in both samples.
