율무전분의 조리과학적 특성에 관한 연구
A study on food scientific characteristics of the Job′s tears flour
초록
율무쌀을 식량으로서의 적합여부를 규명하기 위해 천안산, 횡성산, 의성산 율무쌀을 임의로 선택하여 전분의 분리, amylose 함량 측정, amylogram특성 등의 물성을 측정하고, 율무쌀가루를 여러 혼합비율로 혼합한 식빵과 떡을 제조하여 조리, 적합여부에 대하여 조사한 결과 다음과 같이 요약할 수 있었다. 1. 율무쌀의 전분 함량은 12~20%정도로 쌀이나 찹쌀의 전분함량의 1/3정도이었으며 율무전분의 amylose와 amylopectin의 함량을 측정한 결과 거의가 amylopectin으로 되어있어 찰전분임을 알 수 있었다. 2. 율무쌀전분, 쌀전분, 찹쌀전분의 amylogram에서 호화개시 온도는 각각
In order to make use of Job's tears widely, Job's tears starch was analyzed and determinded the contents of amylose, amylographical and other physicochemical properties. And also the yeast breads and rice cakes were made from flour and rice flours with various mixing ratios of Job's tears flour and then they were tested for suitability to preparation of bread and rice cake. 1. The starch contents of Job's tears showed 12~20%. Which was about one third of rice or waxyrice starch. But amounts of crude proteins, fats, and total ashes in Job's tears were higher than rice or waxyrice. Job' tears starch was composed of amylopectins only, and was similar to that of waxyrice starch. 2. Depends upon the Amylogram of each starch, initial gelatinization temperature of Job's tears starch was the highest among three starches of rice, waxyrice, and Job's tears. Maximum viscosity of Job's tears starch was 860BU, then it was about two times of rice starch viscosity. 3. By the sensory evaluation results, the taste of bread prepared with mixing of 10% Job's tears flour was better than flour bread and the volume and grains of the bread made from mixing of 10%, 20% Job's tears flour were similar to that of flour bread, but the taste, volume and grains of bread made from 30% mixed flour were undesirable. The rice cake Prepared from mixed flour with 25% Job's tears flour has shown to be desirable.
