This study examines the cooking quality, rheology, and sensory characteristics of ramyon noodles made from Korean wheat and arrowroot starch. The control was made from Australian standard wheat(ASW) and the sample was made from Korean wheat. The ratios of arrowwood starch in the sample group were 0%, 5%, 10%, 15%, 20%, 25%, and 30% respectively, and the result was as follows: the yield of the arrowwood starch was 18.8% and moisture level was 14.2%. The lightness(L), redness(a), and yellowness(b) of ASW were 92.07, 1.44, 10.22 respectively, whereas those of Korean wheat were 92.05, 1.55, 11.01, which means the two kinds of wheat showed very little difference in lightness, but Korean wheat had higher degrees of a and b than ASW. The color value of arrowroot starch is L 72.65, a 3.44, b 12.92, so it has a lower degree of lightness and higher degrees of a and b than two kinds of wheat. Dried ramyon displayed a lower degree of lightness and higher degrees of a and b than cooked ramyon, but the first decreased and a increased as we increased the ratio of arrowroot starch in it. The weight of dried ramyon did not show a significant difference among the groups. On the other hand, the weight, volume, water absorption, and the turbidity of cooked ramyon increased as we increased the amount of arrowroot starch in it. The maximum weight, solidity, and elasticity of the control group were greater than those of ramyon made from Korean wheat, but its brittleness was lower. The two groups showed the same degrees of hardness, adhesiveness, and cohesiveness. The maximum weight, solidity, and adhesiveness of the control group increased as we increased the amount of arrowroot starch in it, and the hardness and brittleness were great when the ratio of arrowroot starch was 20%; elasticity was greatest when the ratio of arrowroot starch was 15, 20, and 25%; its adhesiveness and cohesiveness did not depend on the amount of arrowroot starch in it. In the sensory characteristics evaluation, the items that showed significant differences include: appearance (p<0.01), color(p<0.01), smell(p<0.001), transparency(p<0.05), and overall acceptability(p<0.05). The ramyon earned the highest score in appearance when the ratios of arrowroot starch were 5%, 15%, and 20%. As for color and smell, it earned the highest score when it contained 20 and 25% of arrowroot starch. The transparency decreased as we increased the amount of arrowroot starch, and overall acceptability was highest when the ratio of arrowroot starch was 15%. There was a significant difference in overall acceptability between the control and the sample group. As for the loosing speed and chewiness, there was no significant difference between the two groups. When we look at the result of various tests to evaluate the cooking quality, rheology, and sensory characteristics of ramyon noodles, ramyons that contained 15 to 25% of arrowroot starch earned the high scores, and of these the one with 20% of arrowroot starch earned the highest score on all accounts.

The objective of this study was to invesitigate the sensory and quality characteristics of Chicksulgi containing different ratios of ingredients such as arrowroot starch (10%, 20%, and 30%), sugar, honey, oligo-saccharide and water, by sensory evaluation and mechanical examination. The results of sensory evaluation showed that Chicksulgi containing 10% arrowroot starch had higher scores in overall acceptability, color and flavor preference. In the textural analysis of Chicksulgi, the springiness, cohesiveness, adhesiveness were the highest in the samples with 10% arrowroot starch, and the chewiness, gumminess, and hardness were the highest in the 30%-added samples. The hunter's color L value of Chicksulgi was decreased by the increase of arrowroot starch. The more arrowroot starch was added, the redness of Chicksulgi were increased, and yellowness of Chicksulgi were decreased. The moisture content of Chicksulgi was higher in the samples with 10% arrowroot starch than those with 30%.

이 연구는 감마선 조사 칡전분의 레올로지 특성을 알아보아 이것의 가공을 위한 기초자료로 활용하고자 실시되었다. 0-50kGy의 감마선 조사시킨 칡 전분을 3-6%의 용액상태로 만든 뒤 $35^{\circ}C$에서 40분 동안 열을 가하여 호화를 시킨 뒤 rheometer를 이용하여 측정온도 $30^{\circ}C$에서 10-200 rpm의 조건으로 시료액의 유동특성을 알아보았다. 칡 전분 시료 호화액의 레올로지 특성 값은 유동거동 지수 및 항복응력을 고려한 Herschel-Bulkley 방정식을 적용하여 계산하였다. 실험결과 감마선 조사를 하지 않은 것과 5kGy의 감마선 조사를 한 3-6%의 호화 칡 전분 용액의 레올로지 유동거동은 의가소성을 나타내었으나, 10-30kGy의 감마선을 조사한 호화 칡 전분 용액은 ${\tau}_y=0$인 dilatant의 유동거동 특성을 보였다.

The present study replaced Atarigoma with Korea &Chinese sesame values a nd analyzed basic data on various mook to develop Korea's food culture. Contents of oleic acid and linolenic acid in sesame seed were 42.31% and 48.18%, respectively, with a total moisture content of 89.5%. As storage temperature increased, moisture content increased. Cohesiveness and springiness decreased gradually at $4^{\circ}C$ and increased at $20^{\circ}C$, whereas gumminess and chewiness increased at $4^{\circ}C$ and gradually decreased at $20^{\circ}C$. Overall acceptability scores of Japanese and Korean arrowroot starch sesame mook were 7.20 and 7.10, respectively. Korea and Japanese Sesame can be substituted for sweet potato starch, potato starch, and arrowroot starch.

B-amylase(EC 3.2.1.2) was isolated from the root of arrowroot(Peuria thunbergiana Bentham) with distilled water and then fractionated with ammonium sulfate. Crude extract was partially purified by ion exchange chromatography and gel filtration. The enzymatic properties of partially purified $\beta$-amylase were as follows, the enzyme was fractionated with ammonium sulfate between 0.2 and 0.4 saturation, and showed the typical reaction properties of B-amylase producing only maltose from starch. Optinum pH and temperature were pH 6.5, $50^{\circ}C$ respectively. The activity of the enzyme had proportional relations with enzyme protein concentration below 4mg, and had Michaelis constant of 66.7mg% for soluble starch. The enzyme was inhibited by some metal louts such as silver, cadmium, mercury, aluminum, iron and copper.
