We have got the following results from tests in the course of time retrogradation and taste change in bread with added flour of Angelica keiskei Koidz, which had been stored in room temperature (27±2oC), refrigerating(2±1oC) and freezing( 20±1oC), respectively. Bread with the added flour showed a little lower degree of retrogradation than control group, and every group in room temperature retrograded from the very first day. The degree of retrogradation of the group in refrigerating was far greater comparing with the group in room temperature. The longer bread was stored, the lower the degree of retrogradation was, and the higher the adding rate of the flour got, the later its retrogradation happened. Especially the flour of this vegetable's stem turned out to be the most effective in retarding its retrogradation. Group stored 30 days in freezing didn't show a wide difference in retrograde comparing with the group before storage. Preference for color and shape of the flour added bread stored in room temperatue, refrigerating and freezing did not change significantly from the group before storage. Although preference decreased for flavor, texture, mouth feel and overall quality with the lapse of time, flour added group improved in preference for these factors comparing with the control group. Above all, added flour of pretreated stem proved to be the most effective in the sensory tests. With respect to the storing method, the group stored in refrigerating showed greater preference for the texture and mouth feel over the groups in room temperature and freezing. Flavor preference of the group in freezing was the lowest of all.

The quality characteristics of bread with black rice flour were investigated to find the most preferred ratio of black rice flour. Its moisture, ash content, crude protein, crude fat, amino acids, and texture were analyzed. A sensory evaluation was also performed. The moisture and crude fat of bread with black rice flour were decreased in proportion to the added amount of black rice flour, but the crude protein and ash content were increased. The volume of bread decreased as the added amount of black rice flour increased. The pH value of bread increased in proportion to the added amount of black rice flour. The value of brightness and yellowness of the dough were the highest in the control. The added amount of black rice flour was negatively correlated with the brightness and the yellowness of the dough, but was positively correlated with the redness. Total free amino acids were found, and the dough with 5% black rice flour contained the highest amount, followed by 3%, 2%, and 1%. When evaluating the storage days, the springiness and cohesiveness of bread with black rice flour they decreased with time, but the chewiness and brittleness increased. Regarding the taste, preference was given to the bread with 2% black rice flour, which had the lowest rejection rate and was not affected by time in any meaningful sense. The bread with 2% black rice flour won the highest scores in the overall preference measurement.

The purpose of this study is to compare preferences of consumers between food items made from modified cassava flour and plain flour using sensory tests. This study is a qualitative research with an experimental approach and four food items, namely streamed brownies, cookies, fried mushrooms, and seasoning flour have been used for the study. Each of these food items are made from modified cassava flour and plain flour. Panelists wore blindfolds and tasted the food items except the seasoning flour. Based on the data analysis, the panelists have different preferences towards the four food items. The result of the paired Wilcoxon test showed that there is not any different preference in terms of taste of steamed brownies made from mocaf or plain flour, while there is a significant difference in terms of color, aroma, texture, and appearance between the steamed brownies made from mocaf and plain flour. Consumers decide to buy products made from mocaf because these products use local flour and are gluten-free. This article describes the customer's preference based on sensory analysis between products made from mocaf and ones made from plain flour. The result can be used as the basis for developing food items made from local flour and alternative food for customers allergic to gluten.

The effect of using Korean wheat flour versus Australian wheat flour on noodle quality as a result of differing physical and chemical properties of the flours was investigated. The results provided appropriate technical information for selection of wheat varieties to produce high quality Korean salted noodles. Noodle quality was quantified based on measurement of the appearance and texture of noodles. When consumer preference tests were conducted, a firmer and more elastic texture was preferred for Korean white salted noodles, however, when appearance was included in the consumer tests, noodles made with Australian wheat were favored over Korean wheats. Korean flour was found to produce firmer and more elastic noodles, whereas Australian flour produced brighter, creamier colored noodles. In flour quality tests, Korean flours were found to have a higher setback viscosity and lower swelling power than Australian flour. Additionally, Korean flours had higher water absorption values. Protein content of flour was an important parameter affecting the firmness of Korean noodles, whereas setback viscosity and swelling power were the major determinants of elasticity. Overall, the important parameters for determination of the quality of Korean salted noodles were high setback viscosity, low swelling power, and high protein content.

Effects of adding of Angelica keiskei Koidz flour on the quality characteristics of bread were inves tigated. The content of total dietary fiber was 31.89% in flour of Angelica keiskei Koidz leaf and 43.37 % in that of stem. The content of insoluble dietary fiber increased by blanching, but those of soluble dietary fiber and insoluble dietary fiber increased by steeping in NaCl solution. In the results of sensory evaluation of Angelica keiskei Koidz flour, leaf steeped in NaCl solution and blanched stem showed good overall preference. With the addition of Angelica keiskei Koidz flour, water binding capacity and loaf weight increased, while the loaf volume decreased. The loaf volume of bread added with leaf steeped in NaCl solution and blanched stem were higher than those added with natural Angelica keiskei Koidz flour. The lightness and redness values decreased with the increase of Angelica keiskei Koidz flour content in bread but yellowness values increased. In the texture analyzer measurement for bread added with Angelica keiskei Koidz flour, hardness and springiness somewhat increased, while cohesiveness, gumminess and chewiness decreased. As the results of sensory evaluation of bread added with Angelica keiskei Koidz flour, the score of the breads added with 5% leaf steeped in NaCl solution and 5%, 10% blanched stem were somewhat lower than those of control bread. In terms of rate of addition of Angelica keiskei Koidz flour, the bread added with leaf at 5% level, natural stem at 5% level and stem by blanching at 5%, 10% level had good overall preference.

Physicochemical and sensory characteristics of pound cakes containing Angelica gigas NAKAI(Korean Angelica) with various levels of rice flour were investigated in this study. There were significant differences in the specific gravity of dough, and it had the lowest value of 0.848 in the control group. The weight of pound cakes was significantly increased by addition of rice flour, but the volume, specific volume and baking loss rate were significantly decreased by addition of rice flour. The moisture content and pH of pound cakes were found to increase with increasing rice flour content. DPPH radical scavenging activity of the control group was 51.02%, whereas pound cakes with rice flour ranged from 51.90~55.75%. The L value of brightness was increased, but a and b values were decreased significantly by addition of rice flour. In all of items of texture, the control group was higher than those of the pound cakes prepared with various levels of rice flour. Sensory evaluation scores in terms of appearance, flavor, taste, texture and overall preference for pound cakes showed that 50% and 75% substituted sample groups were higher than those of the other groups. The results of this study suggest that addition of 50~75% rice flour is the best substitution ratio for Korean Angelica pound cakes.
