The objective of this study was to investigate the effects and availability of arrowroot powder in making white bread. The characteristics of pasting, farinogram and alveogram of the dough containing arrowroot powder were analyzed. Further, the physicochemical properties of white bread were analyzed by different mixing ratios (0, 3, 5 and 7%) of arrowroot powder during storage periods. When 7% of arrowroot powder was added, the initial pasting temperature of the dough by using a RVA (rapid visco analyzer) was significantly increased. Peak viscosity, holding strength, break down, final viscosity and set back were decreased by increasing added arrowroot powder. With the increasing amounts of arrowroot powder, the values of farinogram and alveogram parameter for the dough showed a tendency to decrement. The texture profile analysis of the white bread revealed that hardness, springiness, cohesiveness and gumminess were increased by adding arrowroot powder and further, the storage time was longer. By increasing the amount of added arrowroot powder, the L value of the white bread was decreased, whereas the a, b value were increased. In the sensory evaluation, the white bread of the control and that of the added 3% arrowroot powder showed the highest preference in total score.

To evaluate the effect of arrowroot(Puerariae Radix) powder on dasik, rice dasik was prepared after supplementation with different ratios (0% 3% 6% 9% and 12% respectively, w/w) of the arrowroot powder. No significant difference in the moisture content was observed among the groups. The pH value was reduced when the arrowroot powder was added. The lightness(L-value) and the yellowness(b-value) of the control group was higher than that of dasik with the arrowroot powder, whereas the redness(a-value) of the control group was lower than that of dasik with the arrowroot powder. In the mechanical evaluation, the hardness of the control group was higher than that of dasik with the arrowroot powder. However, no significant difference in cohesiveness, adhesiveness, gumminess and chewiness was observed. The intensity of the color and flavor of dasik with the arrowroot powder was higher than that of the control group. Dasik with the arrowroot powder was significantly higher in taste and overall acceptability than the control group. In conclusion, 6%(w/w) of the arrowroot powder might be appropriate for arrowroot dasik.

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.

This study examind the product quality characteristics and industrial application of arrowroot powder added Yanggaeng before its industrial application. Several preliminary experiments were conducted by applying manufacturing conditions and varying the amount of arrowroot powder(1%, 2%, 3%, 4%) added to produce Yanggaeng recipes that can be sold commercially. The moisture content of the produce Yanggaeng was low due to the manufacturing standards, but it showed a significant increase with an increase in the ratio, which was similar to the results of other studies on Yanggaeng. The solubility, particale size distribution, and pH also showed a significant increasing trend. The hardness of arrowroot powder added Yanggaeng decreased with an increase in the amount of arrowroot powder, while springiness, gumminess, and chewiness increased with the addition of arrowroot powder. In terms of color, arrowroot powder showed a dark color, which was well suited to white bean paste and could also be used with black bean paste without any problem. These results were due to the manufacturing ratio being adjusted to meet commercial sales standards, resulting in a lower amount of water being used, and the characteristics of arrowroot powder being applied as they were.

Arrowroot Mook was prepared as a trial to develop new food items from natural resources, and its rheological properties were measured. 1. The starting point of gelatinization of 7% arrowroot starch solution was $67.5^{\circ}C$ as measured by amylograph. The viscosity of arrowroot starch reached the maximum 375 B.U. at $95^{\circ}C$ and decreased to 315 B.U. while holding at $95^{\circ}C$ for 15 min. When the temperature dropped to $50^{\circ}C$, the viscosity increased again to 530 B.U. 2. The gelatinization enthalpy of arrowroot starch was 15.603 J/g. 3. For the color, there were significant differences in b value for the arrowroot Mook made of arrowroot starch and in L value for the Mook made by the addition of arrowroot juice. 4. In descriptive analysis, $S_3$(14% arrowstarch) was most favored in color, and $S_1$(10% arrowstarch)was most favored in transparency, brittleness, fineness, and shininess. There were no significant differences in hardness, adhesiveness, and astringency. 5. On the contrary to mechanical measurement, there were no significant differences in hardness of samples as the addition of arrowroot juice increased, although there appeared a tendency to be softer in descriptive analysis. 6. The Mook prepared with 12% arrowroot starch was most favored by sensory evaluation. In case of adding arrowroot juice, the Mook containing 3% of arrowroot juice was most favored. Overall, arrowroot Mook showed a potential as a new food item.

This study was an attempt to use arrowroot, a common plant in Korea used as food to relieve famine, for making noodles and to set up a standard formulation for arrowroot-starch-containing noodle. Arrowroot starch was mixed with wheat flour at a different ratio and used to make noodles. Cooking quality and texture were measured, and sensory evaluation was performed with the noodles prepared. Water binding capacity of arrowroot starch was higher than that of wheat flour. Maximum viscosity of the composite arrowroot-wheat flours was increased as the arrowroot starch content increased as measured by amylograph. Addition of arrowroot starch at 10% level improved the quality of noodles. Texture measurement showed that the noodles of the composite flour containing 10% or 20% arrowroot starch were superior to those of wheat flour alone； however, the scores of arrowroot-con-taming noodles were similar to those of wheat flour alone in sensory evaluation.

In this article, arrowroot is extracted in distilled water, and its dyeing properties on wool, nylon, and silk were investigated. Also the effect of mordanting (Al, Cu, Sn, Fe and Cr compounds) on the wash fastness are measured. The wavelength of maximum absorption of the arrowroot extract appears at 250 and 300nm below pH 7, but they shifted to longer wavelength at higher pH values. It appears that the optimum condition of the dyeing of wool, nylon, and silk fabric with arrowroot extract is $60^\circ{C}$, 60 min, and pH 4.0. Mordant treatments are effective in improving wash fastness of polyamide fabrics.
