  • The principal objective of this study was to determine the appropriate water content for optimal texture in high omega-3 fatty acid saury nuggets. The approach adopted in this study essentially involved variations in water levels(0{\sim}25%$). The main ingredients of the nuggets included saury mince, mild pizza cheese and hydrated textured soy protein concentrate. The formulated products were molded(dia. 4.5, thickness 1.5 cm, 20 g), battered lightly, flash-fried far 4 min at $160^{\circ}C$ and frozen until they were tested. The frozen nuggets were cooked to $65^{\circ}C$, then subjected to sensory evaluation, texture analysis at 80% deformation, and expressible fluid tests. The moisture contents in the nugget batter and the cooked nuggets were determined. In our sensory evaluation, nugget texture was adjudged the best in the nuggets prepared with a 20% water level(S5). The hardness and chewiness in the nuggets were reduced with increases in the water level. However, when the nuggets contain more than 15% water(S4, S5, S6), we noted no significant differences in the hardness values. The difference in moisture content between the uncooked nugget bat or and the cooked nugget was most profound in the nugget prepared with a water level 25%(S6). The nugget prepared with a water level 25% was also the highest in expressible fluids, and was also highest in internal moisture content. The texture preference of nuggets was correlated positively with moistness(r=0.881) and moisture content(r=0.827), and correlated negatively with firmness(r=-0.870) and cohesiveness(r=-0.839), and these correlations were significant.

  • The purpose of this study is to investigate the antimicrobial effect of mugwort (Artemisia asiatica Nakai) on the rice cake and bread preservation, and to identify their antimicrobial compounds. The mugwort extracts showed complete inhibition on the growth of Bacillus subtilis and Staphylococcus aureus at 250 $\mu\textrm{g}$/ml level. Antimicrobial activi쇼 of mugwort extract were stronger than that of commercial antimicrobial agent. Five % of sodium propionate solution showed complete inhibition on the growth of B. subtilis, E. coli and S. aureus, but L. plantarum was inhibited 50.87% at the same concentration. When various amounts of freeze-dried mugwort powder were added in sulgis (steamed rice cake), 3% ssooksulgi (mugwort powder added sulgi) had quite lower level of total bacterial count (5.5$\times$$10^/5 CFU/g) compared with the control group (1.4$\times$$10^/7 CFU/g) at ambient temp. (30$\pm$1$^{\circ}C$) after 72 hr. Three % addition of mugwort showed 2 days extention of shelf-life of rice cake. The sensory qualities of ssooksulgi has no significant difference in moistness, consistency, cohesiveness, afterswallowing and overall quality compared with control group. Ssooksulgi with 3% of mugwort powder had the best overall quality in sensory test. The methanol extract of 500 $\mu\textrm{g}$/ml of mugwort could lead the successful retardation of the growth of putrefactive microorganism during the incubation of rice cake at 37$^{\circ}C$ for 24 hr. On the other hand, coumarin (Sigma) had 54% inhibitory effect at 500 $\mu\textrm{g}$/ml level, and (E,E)-2,4-decadienal completely inhibited the growth of putrefactive microorganism of whitesulgi at 100 $\mu\textrm{g}$/ml level during the incubation at 37$^{\circ}C$ for 48 hr.48 hr.

  • This study was carried out to investigate the quality characteristics of Baiksulgis made of imported rice(Thai and Chinese rice, harvested in 1998) and domestic rice(Chuchung byeo, harvested in 1998 and 1997). Moisture content, color value, yields of reducing sugar by $\beta$-amylase reaction, texture and sensory properties of Baiksulgis were measured. Moisture contents of rice flour and Baiksulgi made of Korean rice harvested in 1997 were highest and those of Thai rice were lowest among the samples. This tends were also seen during storage. Lightness and redness of Baiksulgi made of Thai rice were lowest and yellowness of Baiksulgis made of Korean rice harvested in 1997 and Chinese rice were higher than those made of other rices. Yield of reducing sugar by $\beta$-amylase reaction was highest in Baiksulgi made of Korean rice harvested in 1998 and lowest in Baiksulgi made of Thai rice. And the value decreased less than half of initial value after 24 hour storage. Adhesiveness of Baiksulgi made of Thai rice was zero and cohesiveness, chewiness and gumminess of that were very low. This results showed that Baiksulgi made of Thai rice was lack of chewy texture and this trend was more apparent as the storage time increased. In sensory tests, Baiksulgi made of Chinese rice had most yellowish color and that made of imported rice such as Chinese and Thai rice had more coarse texture than that made of domestic rices. off odor was lowest in Baiksulgi made or Korean rice harvested in 1997 and sweet taste was lowest in that made or Thai rice. Hardness adhesiveness, moistness and chewiness of Baiksulgi made of domestic rices were much higher than those made of impoted rices, and these results showed that Baiksulgi made of domestic rices had acceptable texture. Baiksulgi made of Thai rice showed the lowest acceptability due to lack of above textural characteristics and it was needed to add the material to modify the texture of that.

  • The purpose of this study was to investigate the quality characteristics of Sulgidduk prepared by adding the optimal amount of apple powder. Five different mixture ratios of apple powder to rice flour were prepared (0, 4, 8, 12, and 16%). After being stored for 3 days, the mixtures of apple powder and rice flour were measured to determine moisture content, color values, sensory qualities, and the mechanical texture characteristics of Sulgidduk. Moisture content of Sulgidduk with added apple powder ranged from 36% to 39% and but decreased with significantly with added apple powder. The L-color value decreased, whereas both the a-and b-values increased as apple powder was added. Thus, apple peel likely affected the Sulgidduk color value. The pH of Sulgidduk decreased with the addition of apple powder, whereas sugar level increased as apple powder was added. In the mechanical evaluation of apple Sulgidduk, hardness was significantly higher during the 3 days of storage with increasing amounts of added apple powder. Cohesiveness increased significantly during the storage period with the addition of apple powder,-; however, it began to decreased after 3 days. Springiness increased significantly with the addition of apple powder. Both adhesiveness and chewiness of Sulgidduk increased with added apple powder. Sensory quality characteristics such as color, taste, flavor, and moistness were improved with increasing amounts of added apple powder. However, the sensory quality of Sulgidduk decreased when the ratio of apple powder to rice flour was greater than 25%. Consequently, a mixture of 15~20% apple powder to rice flour was the best formula for improving Sulgidduk in terms of sensory quality.

  • We examined clinical and reseach data about abdominal palpation conducted in japanese oriental medicine from the early stages of its medical history to the latest research, so as to introduce it into korean oriental medicine. That is to say, we studied clinical significance and suitable oriental medicine prescription about following : sweat and moistness of abdominal skin ; temperature of abdominal skin ; palpation and visible peristaltic movement ; meteorism ; tonus of the whole rectus abdominis muscle ; local tonus of parts rectus abdominis muscle ; palpitation of abdominal aorta ; resistance tender on pressure in epigastric region, subcostal region, umbilical region, lower abdomen, para-umbilical region, cecal region, sigmoid region and inguinal region ; sound of fluctuating liquid in the epigastric region. The result was that abdominal palpation was an immediately applicable method of clinical diagnosis in oriental medicine, and is being proven by western medicine methodology today. Therefore we suggest that korean oriental medicine would advance greatly if abdominal palpation were applied.

  • The principal objective of this study was to develop a processed food using aged garlic. Pound cake samples were prepared with semi-solid aged garlic at levels of 0, 5, 10 and 15% ($25^{\circ}C$, 7 days). The pH of the batter prepared with the aged garlic ranged between 6.79 and 7.01 and the control pH was 7.21. The specific loaf volume of the pound cake prepared with the addition of 5~15% aged garlic decreased, from 2.78 to 2.51 cm3/g. The baking loss rate of the pound cake prepared with 0~15% added aged garlic also decreased by 6.91~6.42%. The lightness, redness, and yellowness values of the pound cake decreased with increases in the percentage of aged garlic. The adhesiveness, gumminess, and chewiness of the samples did not differ significantly with differing amounts of added aged garlic. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, however, was improved significantly via the addition of aged garlic. In the sensory evaluations, the pound cake prepared with 10% added aged garlic received higher acceptance scores for the properties of smell, taste, softness, moistness, adhesiveness and overall acceptability. Consequently, the optimal quality achieved in this set of experiments was with a pound cake to which 10% aged garlic had been added.
