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.

The characteristics of Heunmi (brown waxy rice)-ssuck (mugwort)-injeolmi containing different contents of mugwort over a storage period of 2 days were studied. The pH level ranged from 6.4 to 6.5, whereas moisture rate ranged from 34.4 to 51.4% with different amounts of mugwort. Heunmi-ssuck-injeolmi with different amounts of mugwort showed significantly different characteristics in the texture analysis. Hardness, gumminess and chewiness all decreased, whereas adhesiveness, springiness and cohesiveness increased with greater amount of mugwort added. Colorimeter analysis showed that L-, a- and b-values of Heunmi-ssuck-injeolmi were inversely proportional to the amount of mugwort. Scanning electron microscopy (SEM), confirmed that the stoma size of Heunmi-ssuck-injeolmi was directly proportional to the amount of mugwort, whereas the largest stable stoma size was observed with 30% mugwort. In the control group, retrogradation was preceded by expelling water, known as syneresis, whereas Heunmi-ssuck-injeolmi showed less retrogradation with a higher moisture rate. It is expected that mugwort containing cellulose discourages the retrogradation process. In conclusion, 30% mugwort showed the least retrogradation and was the most preferred in terms of taste with stable stoma over the storage period at $25^{\circ}C$. Therefore, it is appropriate for the manufacture and commercialization of Heunmi-ssuck-injeolmi.

This study was conducted to investigate the influence of dietary mugwort on physico-chemical characteristics and processing characteristics in meat sample of chicken meat. Broilers were randomly assigned to one of four dietary treatments: 1) Control(commercial feed) 2) T1(commercial feed supplemented with 1% mugwort) 3) T2(commercial feed with 3% mugwort) and 4)T3(commercial feed with 5% mugwort). They were fed one of the experimental diets for five weeks and slaughtered. After that, the meat samples were vacuum packaged and stored at 4${\pm}$1$^{\circ}C$. The physico-chemical characteristics and processing characteristics were analyzed for meat samples stored over a period of 0, 1, 2, 3 and 4 weeks. The pH of all treatments significantly increased during the storage periods(U<0.05). The pH of the thigh was rather higher than that of the breast. The drip loss and heating loss tend to decrease in dietary mugwort group(p<0.05). The WHC(water holding capacity) of all treatment was significantly increased during storage(p<0.05). The meat color was increased during storage.

This study was performed to investigate the influence of vadrious dietary fiber sources such as mugwort, apple, sea mustard, butterbur on the intestinal in aged rats. Nine groups of aged rats (12months after weanling) were fed each experimental diet containing 5% and 15% dietary fibers for 4 weeks. The contents in large intestine of aged rats used for the measurement of intestinal microflora. Total viable counts and the numbers of Bifidobacterium, Lactobacillus, Clostridium, E. coli and Staphylococcus were determined by nonselective medium and various selective media. The intake of dietary fiber sources employed did not show any differece in the number of total microorganisms, Lactobacillus and Bifidobacterium. It was remarkable that Clostridium perfringens appeared in the colon of aged rats. The prpulations of Peptococcus and Clostridium were significantly larger in the apple 5% group than in other dietary fiber groups while the number of Staphylococcus was significantly smaller in the dietary fiber groups than in cellulose group. And the Streptococcus populations decreased in the mugwort 15% group. Accordingly, the mugwort 15% group is effective in improving intestinal flora of aged rats.

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.

This study was conducted to investigate the influence of dietary mugwort (0, 1, 2, 4%) and sardline oil(1%) on weight gain, pH, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), and meat color in meat-type chickens. Birds were randomly assigned to the four dietary treatments: control (commercial feed), control plus 1% mugwort and sardine oil (T1), 2% mugwort and 1% sardine oil(T2), or 4% mugwort and 1% sardine oil (T3). Birds were sacrificed and meat samples were taken and stored for either 0, 3, 7 or 10 days at $4^{\circ}C$. Weight gain in T3 was lowest than other treatment groups (P<0.05). pH of dietary mugwort and sardine oil treatments increased significantly compared to that of control during storage periods (P<0.05). VBN and TBARS of all treatment groups were significantly increased as storage period extended (P<0.05). Meat color $(L^*,\;b^*)$ significantly increased during storage periods. $L^*\;and\;b^*$ values were higher in treatment groups than in control (P<0.05). These results indicate that the mugwort and fish oil may improve quality and self-life of meat-type chickens during storage.

This study was performed to investigate the influence of dietray food from the three CHinese medicinal herbs(Mugwort, Dried organge peel and Duchung) on lipi d metabolism in rats. Male rats of Sprague-Dawley strain were divided into four dietary groups(Cellulose (CL), Mugwort(MW), Dried organge peel9OP), Duchung(DC)) after three weeks of hyperlipidemic dieting and were fed ad libitum each of the experimental diets for six weeks. The fiber sources of the experimental diets were prepared by drying and milling mugwort, orange peel, duchung and cellulose. Each of the Fiber sources was mixed into the diet to achieve 10g% levels of total dietary fiber. Levels of apparent fat absorption exhibited a significant decrease in the MW and DC groups. The OP group also showed a decreasing trend, but to a lesser extent. The levels of serum total lipid were not significantly different among the four experimental groups. Total serum cholesterol levels were significantly lower in the OP grop that in both the CM and MW group. Serum TG and LDL-cholesterol levels were significantly higher in the DL group than other groups. Serum HDL-cholesterol levels were significantly levels were significantly lower in the CL group than in the other groups. Total lipid and total cholesterol in liver were significantly higher in the CL group than in the other groups. Total lipid and total cholesterol in feces displayed a significantly increase in the MW and DC groups when compared with the CL group. The OP group also showed an increase compared to the CL group.

This study was designed to elucidate the effects of mugwort powder supplemented to high fat diets on blood components levels in rats. The levels of mugwort content in the experimental diets were divided into 12, 21, 28% and the fat levels in high fat diet was 30% of total caloie intake. Forty-nine male Sprague-Dawley rats weighing 72.5$\pm$0.3g were divided into group I(add mugwort during 8 weeks), group II(add during 4 weeks) andcontrol group. The results of this study were summarized as follows : 1. There were no difference in body weight gain and FER throughout eight weeks of experiment. The organ weights were somewhat higher in control group, but not significant. 2. The mugwort groups(I, II) were significantly higher than control group in RBC. This result showed that the mugwort affect the content of RBC. Author would like to conclude this result that the RBC content of experim-ental animal was affected by the iron in the mugwort. There were no difference among experimental groups in Hb, Hct. 3. It was noteworty that the concentration of serum glucose and triglyceride in the mugwort groups(I, II) was significantly lower than the control group. This result concluded that concentration of serum glucose and triglyceride which had become high by high fat diet were affected by the calcium or dietary fiber in the mugwort. There were no difference among experimental groups in albumin, total cho-lesterol, HDL-cholesterol.

A total of fifty Hanwoo steers raised from 14 to 29 months were used to investigated the effects of dietary mugwort on the performance and meat quality during refrigerated storage. A feeding trial was tested for 14.7 months and experimental diets included 0 and 2% dried wild mugwort. Total weight gain and average daily gain in this study were significantly higher in mugwort treatment than control treatment. Feed efficiency was improved by mugwort treatment compared with control treatment. Any difference in GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrubic transaminase), and BUN (blood urea nitrogen) was not observed between groups. Carcass weight and longissimus muscle area were higher for mugwort treatment than control. As fattening increased, total cholesterol in blood increased. Total cholesterol in blood tended to be lower in mugwort treatment than control treatment (p<0.05). The heating loss, $L^*$, $a^*$, $b^*$, chroma, and hue unit of all treatments were not affected treatment, but showed a significant decrease in all treatments during refrigerated storage. For fatty acid composition in longissimus muscle, dietary mugwort supplementation increased unsaturated fatty acid than saturated fatty acid (p<0.05). Based on these findings, it is obvious that supplementation of mugwort at 2% level will be useful to decrease cholesterol, increase unsaturated fatty acid, and improve growth performance of Hanwoo steers.
