  • This study was conducted to assess the effects of mugwort powder (3% and 5%) on sponge cake made with medium and cake flour. After preparing sponge cakes with mugwort powder, the water activity (Aw), softness and color of crumbs were tested and the sensory properties were evaluated. The water activity of the sponge cakes containing different quantities of mugwort powder did not differ greatly. The springiness and hardness of the sponge cakes with mugwort powder were all lower than that of the control. With regard to the color of the sponge cakes, the L values were reduced, but the a and b values were increased in response to the addition of mugwort powder, resulting in the sponge cake containing mugwort having a darker color. The micrographs of the sponge cakes with mugwort powder showed a slightly lower porosity than the control. In addition, the results of the sensory test showed that cakes containing mugwort powder had low scores. However, it is still possible to make the sponge cakes using mugwort powder and the sponge cakes prepared with flower containing 3% of mugwort powder had better evaluation than those prepared using other amounts of mugwort powder.

  • This study was designed to investigate the possible utilization of mugwort as a source of functional ingredients. The approximate composition for mugwort powder was 5.06% moisture, 1.98% crude protein, 4.65% crude fat, 5.85% ash and 82.46% carbohydrate. The highest mineral content was potassium. The contents of total phenolic compounds and condensed tannin were 114 mg% and 11,000 mg%, respectively. The highest electron donating ability(EDA) was observed from the ethyl acetate and butanol fractions of mugwort powder but the lowest was shown by the hexane fraction. In color values, with increasing mugwort powder content, the 'lightness', 'redness' and 'yellowness' decreased in the crust, while in the crumb bread the 'lightness' decreased and the 'redness', and 'yellowness' increased. With the addition of mugwort powder as a substitute for strong flour over the range from 2.5% to 10.0%, the ratio of the volume and specific volume of white bread decreased while its weight increased. In the texture measurements for white breads, the hardness decreased slightly with the addition of 2.5% mugwort powder, but then increased with further additions of mugwort up to 10.0%. The addition of 2.5% mugwort powder increased the springiness and gumminess of white bread. The highest sensory scores for color, flavor, taste, texture and overall acceptance as evaluated by a student sensory panel were obtained from white bread with 2.5% mugwort powder and from the control. The highest sensory scores as evaluated by a baker sensory panel were obtained from white bread with 2.5% mugwort powder. In ranking test, overall acceptability of white bread was the highest in the control. Overall acceptance scores by sensory evaluation of white bread with 2.5% mugwort powder were not significantly different from those of control.

  • As a result of the sensory test for Bechamel Sauce being prepared by varying the amount of frozen-dry mugwort, the moisture content was the highest at 83.56% in the control group and the lowest at 76.18% in the one containing 20% of mugwort. The pH level decreased significantly (p>0.001) as the addition of specimen increased. In case of color, the brightness (L) and redness (a) were highest at 81.54 and -0.85 within the control group, and the yellowness (b) was highest at 35.82 for the one containing 20% of mugwort. The viscosity was the lowest at 64.45 cp for the control group and 138.45 cp for the Bechamel Sauce containing 20% of mugwort. Reduced sugar was significantly increased (p>0.001) with the addition of specimen. The results of change in the total number of bacteria showed that there was no microorganism until the third day of storage. On the fifth day, the groups with up to 10% mugwort showed $1.6{\times}10^2$ CFU/ml microorganisms and the groups containing 15% and 20% of mugwort were free of microorganisms. All groups contained microorganisms on the seventh day of storage, but the groups with greater mugwort contents showed smaller number of microorganisms on the fifth and tenth days. Taking into acoount the DPPH free radical removal of brown sauce containing mugwort, the removal increased with greater mugwort content. In terms of preference test, the color was 3.5 for the control group without the mugwort and the taste was highest at 5.1 with 10% of mugwort. The group containing 15% of mugwort received the highest score (4.6) for the after taste and the viscosity was the lowest at 2.7 for the group containing 20% of mugwort. Overall acceptability was the highest at 5.3 for the group containing 10% of mugwort and the lowest for the group containing 20% of mugwort.

  • This study was conducted to investigate the effects of mugwort powder on two types of flour batters, i.e., medium and cake, using the Falling Number test, RVA test, alveogram, and farimogram. The mugwort powder was added at 3% and 5% on the medium and cake flour bases, respectively. The Falling Numbers of the medium and cake flour batters with mugwort powder were increased due to the alteration of the protein in the flour. Analysis of the RVA characteristics showed that the addition of mugwort powder did not have significant effects on the initial pasting temperature. Peak viscosity, holding strength, final viscosity, and set back values of the medium flour batter were not consistent, but those of the cake flour batter were decreased. The characteristics of the alveogram showed that the addition of mugwort powder increased the extensibility and the swelling index. Farinogram demonstrated that the addition of mugwort powder decreased the water absorption and improved the stability of the medium and cake flour batters.

  • The effects of mugwort on some physicochemical properties of rice flour, on the viscosity of rice flour pastes (2 and 4%), on the hardness and the freeze-thaw stability of rice flour gels (20 and 40%), and on the degree of gelatinization (DG) of pastes and gels were investigated. By addition of mugwort, water holding capacity, swelling power, and solubility of rice flour were increased. The rice flour pastes became thicker by addition of mugwort, but viscosities of both the rice flour pastes and the rice flour-mugwort pastes, without noticeable difference between them, were decreased during storage at $25^{\circ}C\;and\;4^{\circ}C$ for 7 days. The rice flour gels became firmer by addition of mugwort and hardnesses of both the rice flour gels and the rice flour-mugwort gels were increased during storage, especially at $4^{\circ}C$. DGs, measured by glucoamylase digestion, of pastes and gels were decreased slightly during storage. Freeze-thaw stability of gels was not affected by addition of mugwort.

  • This study was carried out to investigate the fermentation characteristics and storage of set-type yoghurt added mugwort extracts(AME) such as pH, growth of lactic acid bacteria, number of viable cells, viscosity, and sensory characteristics during 24 hours fermentation and 15 days storage. Addition of mugwort extracts was grown rapidly of lactic acid bacteria rather than that of control and also 4 or 8% AME groups were grown similar to control. The drop of AME pH of broth was less compared with control during incubation of lactic acid bacteria. The growth of lactic acid bacteria during incubation of AME yoghurt was not different of viable cell count between AME group and control in beginning time, but the viable cell count of AME groups were increased depended opon addition quantity of AME in ending time. Addition of mugwort extracts was not affect on pH change during yoghurt fermentation and increased a lactic acid bacteria number as well as no effect of yoghurt fermentation in ending time. The viscosity of yoghurt was almost not changed 3 hours after yoghurt mix and increased rapidly 6 hours after yoghurt mix. Although control and 0.5% AME group showed maximum viscosity at 18 hours of fermentation, 1 and 2% AME group showed linear increase until 24 hours of fermentation. Mugwort did not affect pH and viable cel number of lactic acid bacteria during 15 days storage 24 hours after fermentation. Sensory evaluation of the AME yoghurt showed that flavour, texture and acid taste were not affected by addition of mugwort. However, the appearance and taste were dropped by addition of mugwort.

  • The purpose of this study was to develop new method for the manufacture of Yukwa, a Korean oil-puffed rice snack with a soft texture, using a far infrared ray electric roaster. The Yukwa base is traditionally expanded using oil, but the Yukwa base tends to develop unpleasant rancid odors or off-flavors during storage. In this study, the DPPH radical scavenging activity of mugwort powder was evaluated. Baked and fried Yukwa samples were added with 0.5, 1.0, 1.5, and 2.0% of mugwort powder and left untreated as a control, and then tested for moisture content, expansion rate, color, hardness, and sensory evaluations. The samples with higher concentrations of mugwort powder, evidenced a more profound tendency toward DPPH radical scavenging activity. The moisture content of Yukwa dough tended to increase with the addition of mugwort powder. As the mugwort powder content increased, the moisture contents of the Yukwa base and the Baked Yukwa increased. The moisture content and expansion rates of the fried Yukwa did not differ significantly. The samples containing the mugwort power evidenced a lower expansion rate than was observed in the control group. The lightness of the baked and fried Yukwa was reduced with increased mugwort powder content. The greenness of the baked and fried Yukwa was at a minimum upon the addition of 2.0% mugwort powder. The yellowness of the baked Yukwa did not differ significantly between the samples. As the mugwort powder content increased, the yellowness of the fried Yukwa increased. The hardness of the baked and fried Yukwa tended to increase with the addition of mugwort powder. In the sensory evaluations, the baked Yukwa scored higher than the fried Yukwa, and all of the sensory characteristics of baked Yukwa scored highest in the samples without mugwort powder, but also scored fairly well with 1.0 and 1.5% mugwort powder. In conclusion, these results demonstrated that 1.0~1.5% of mugwort powder should be added to Yukwa baked in a far infrared ray electrical roaster in order to optimize physiological functions and keep overall acceptability reasonably high.

  • This study was conducted to examine the applicability of muffins and the optimal ratio of batter mixture by adding mugwort with various functions and physiological active substances. In result of examining the quality characteristics of muffins after adding frozen-dried mugwort powder by 0%, 1%, 3%, 5%, or 7%, the moisture retaining capacity of muffin batter was lowest with MPM0, the control group, and the deposition was highest at $17.94m{\ell}$ with MPM0. The pH value of muffin batter was highest at 8.62 with MPM0 and moisture decreased significantly (p<0.001) when more mugwort powder was added to the sample. The brightness increased significantly (p<0.001) when the amount of frozen-dried mugwort powder decreased and redness and yellowness decreased when the addition of mugwort powder increased. The height and volume of mugwort muffins were lowest at 4.75 cm and $135.69m{\ell}$ with MPM7 with the greatest value of frozen-dried mugwort powder. The loss at baking of mugwort muffins was lowest at 2.27% with MPM7. The hardness of mugwort muffins was highest with MPM7 with the highest mugwort powder content. Coagulation and resilience was highest at 0.64 with the MPM0 control group and the chewiness increased significantly (p<0.001) with greater amount of frozen-dried mugwort powder. The appearance of mugwort muffins was highest at 6.1 with MPM5 and the most preferable color and flavors were found with MPM3. Tenderness was highest with the MPM0 control group. Overall preferability was highest with MPM3 with 3% frozen-dried mugwort powder. When adding frozen-dried mugwort powder to muffins, the 3% and control groups mostly showed the highest values, whereas the 5% group and higher groups showed lower values.
