Abstract
The purpose of study was to improve the storage time of breads with spices. The quality of breads with garlic, ginger and cinnamon powder containing 1% concentration were investigated using sensory and mechanical evaluation. For 14 days, total microbial count and chemical properties were analyzed at 18℃ The result of sensory evaluation was not significantly different between control and breads with spices powder. But breads with spices powder were significantly higher than control in texture and acceptability. Especially, bread with cinnamon powder was most favorable in acceptability. The result of total microbial count showed that breads with spices powder were reduced with storing time passed and bread with cinnamon powder was most reduced in breads with spices powder. As storing time passed, moisture contents and pH range were decreased and L, a and b value were decreased in all breads. Hardness, gumminess and brittleness of texture analysis were increased as storing time passed, but sprinsiness and cohesiveness were decreased. A negative correlation was observed between the sensory and mechanical properties in general. Sensory properties of springiness and swelling were positively correlated with the acceptability. In the analysis of correlation between the chemical and mechanical properties showed that lightness of mechanical properties had positive correlation with pH range and moisture contents. Moisture contents of chemical properties had negative correlation with hardness, but had positive correlation with cohesiveness of mechanical properties.

Abstract
Rice cakes were prepared by the addition of yellow soybean flour or peanut flour and packaged with CO_2-modified packaging(CMP) or vacuum packaging(VP), and their physical characteristics were monitored by sensory evaluation and mechanical measurement while storing for 6 days. For VP samples, yellow soybean rice cake showed little changes in cohesiveness, moistness and chewiness for 6 days of storage, while pure rice cake and peanut rice cake showed an increase in strength and hardness from the 4th day of storage. In case of CMP, yellow soybean rice cake hardly showed a difference in cohesiveness, moistness and chewiness for 6 days, while pure rice cake and peanut rice cake showed a significant difference from the 4th day in sensory evaluation. For rheometer measurement, yellow soybean rice cake with CMP or VP showed little changes in strength or hardness for 6 days, while peanut rice cake and pure rice cake showed a drastic decrease in cohesiveness from the 2nd day and adhesiveness from the 4th day of storage. As there was no remarkble difference or deterioration for 6 days of storage in yellow soybean rice cake between CMP and VP, the ingredients of rice cake appeared to be more important than the type of packaging in terms of the quality deterioration of rice cake.

Abstract
The objective of this study was to evaluate the effect of functional herbal foods on the growth of intestinal lactic acid bacteria. When Bifidobacterium breve and human intestinal microflora were inoculated in the general anaerobic medium which contained each functiona1 food water extract, most of functional herbal foods induced the growth of lactic acid bacteria by decreasing pH of the broth. The pH decreasing effects of Liriip platyphylla and Platcodon grandiflorum were excellent. The growth of lactic acid bacteria effectively inhibited the bacterial enzymes, β -glucosidase and β -glucuronidase. Engenia caryophyllata and Liriipe platyphylla potently inhibited the productivity of β -glucosidase of B. breve and human intestinal bacteria. Cinnamomum cassia, Gardenia jasminoides and Platycodon grandiflorum potently inhibited the productivity of β-glucuronidase of human intestinal bacteria. The growth component isolated from Platycodon grandiflorum was sucrose (compound B).

Abstract
We studied the effects that the addition of Kimchi has on microbiological properties of fermented sausages as we observed pH and microbiological changes of Kimchi-added fermented sausage by aging period. The pH figure of sausages added with commercial starter culture was 5.69 at the beginning stage and declined gradually to 5.01. The more Kimchi is added, the lower pH figure goes. Sausages with 10% and 20% of fresh Kimchi, and 2% and 4% of powdered Kimchi added, showed about pH 5.4 at the early stage and down to pH 4.87 as they are stored longer. In terms of microbiological changes, sausages mixed with starter culture showed 10＾7cfu/g level in the number of total bacteria, lactic acid bacteria, yeast and fungi, lower than Kimchi-added sausages. However, the figure soared sharply to 10＾10cfu/g during the aging period. Kimchi-added sausages recorded 10＾9cfu/g, slightly high during the early aging stage, in the number of total bacteria, lactic acid bacteria, yeast and fungi, while showing a gradual increase up to 10＾10cfu/g towards the end of aging period and became microbiologically stabi1ized .

Abstract
The purpose of this study was to develop a standardized recipe of Hwajeun(glutinous rice pancake with flower) by evaluating various methods appeared in the literature. For this purpose, the effects of the volume and temperature of water used to make dough on the sensory and rheological characteristics of Hwajeun were investigated. This experiment consisted of sensory evaluation in acceptance and intensity(appearance, color, moistness, softness, chewiness, adhesiveness, taste and overall preference), objective evaluation by using texture analyser, color difference meter and measurement of water content and oil absorption ratio. The loss ratio of moisture contents between dough and cooked Hwajeun were 2.4∼2.8%, and the oil absorption ratio of Hwajeun made by 20℃ water for kneading increased in proportion to the increment of water added(p<0.01). In terms of color, b value of Hawjeun made by 104℃ salted water for kenading showed higher value compared to the others. In the two bite compression test, adhesiveness, springiness, gumminess and chewiness of Hwajeun made by 20℃ water(36%) for kneading showed significantly(p<0.05) high value among the samples. As a result of sensory evaluation, Hawjeun made with 27% of 104℃ salted water for kneading was most preferred in softness, chewiness, taste and overall preference.

Abstract
Effects of added green tea powder and Angelica keiskei powder on the quality characteristics of Yukwa were examined for the purpose of improving functioanality and variety of Yukwa, and usage of green tea powder and Angelica keiskei. Dietary fiber contents of green tea powder were 5.2% soluble dietary fiber, 22% insoluble dietary fiber, while Angelica keiskei contained 28.9% soluble dietary fiber, 29.6% insoluble dietary fiber. Expansion rate of yukwa was 3,675% for control and the rates were slightly decreased as the addition level increased. Although Yukwas added 6% green tea and angelica keiskei powder were harder than the others when determined by rheometer, sensory evaluation results showed that hardness and mouthfeel were soft without any significant difference among the control and experimental samples. And internal structure of 4 and 6% green tea powder and those added angelica keiskei at three levels were evaluated by sensory panel as moderately compact. Overall acceptability of yukwa added 2% green tea powder was the best of all while yukwas added angelica keiskei at three levels were evaluated as good. The results of peroxide value and TBA value showed that green tea powder had stronger antioxidative property than angelica keiskei. In conclusion addition of green tea powder by 2% level and angelica keiskei powder up to 4% would give us beneficial effects in the aspects of functionality and storage life of yukwa without any detrimental effects on the quality characteristics of it.

Abstract
This study aimed for exploring the best recipe of Seosokbyung with different ingredient ratios of glutinous millet flour, sugar, and water added to rice flour. The most desirable recipe was detetmined by sensory evaluation and mechanical test for measuring texture, moisture content and colorimetry. The best score for each sensory item was obtained in the following condition: Color-245g(70%) of glutinous millet flour, 50g of sugar with 10㎖ of water in 105g of rice flour. Flavor-175g(50%) of glutinous millet flour with a 80㎖ of honey in 175g of rice flour. Graininess and Moistness-245g(70%) of glutinous millet flour with 70㎖ of honey in 105g of rice flour. Chewiness-210g(60%) of glutinous millet flour, 60g of sugar with 20㎖ of water in 140g of rice flour. Sweetness-175g (50%) of glutinous millet flour 7g of sugar with 25㎖ of water in 175g of rice flour. As a result of mechanical examination, the best score for springiness, cohesiveness, chewiness, gumminess, adhesiveness was obtained in the recipe of 175g(50%) of glutinous millet flour with 80㎖ of sugar in 175g of rice flour, and that for hardness in the one of 245g(70%) of glutinous millet flour with 70㎖ of honey in rice flour. As the less amount of glutinous millet flour was added, the scores for springiness, cohesiveness, chewiness, gumminess and adhesiveness were increased, and the addition of honey gave higher scores than sugar or oligosaccharide(P<0.05) The best recipe of Seosokbyung was 140g of rice flour, 210g of glutinous millet flour, 60g of sugar, 20㎖ of water and 3.5g of salt. The moisture contents of rice flour and glutinous millet flour were 31.6% and 13.3%, respectively. The content of moisture in the best recipe of the Seosokbyung is approximately 36.101%. The moisture content higher than 36% gave better sensory scores in chewiness and moistness. As a result of colorimetry, the most bright `L` value(Lightness) was obtained from 175g of rice flour mixed with 175g(50%) of glutinous millet flour, 70g of sugar and 25㎖ of water. The highest `a` value(Redness) was gained from 175g of rice flour mixed with 175g (50%) of glutinous millet flour and 80㎖ of honey. The best `b` value(Yellowness) was obtained from 140g of rice flour, 210g (60% of rice flour) of glutinous millet flour, 60g of sugar and 20㎖ of water.

Abstract
Related to the desire to expand our knowledge on the use of natural spices, this study was carried out. Quality chararteristics of bread such as water holding capacity, loaf volume and weight, color value, mechanical characteristics and sensory evaluation were investgated by being added flour of Coriander leaf and seed. The results of the experiment are as follows: Among the proximate composition of bread added with the Coriander flour, the content of crude protein and curde ash was higher in the bread added with Coriander leaf and Coriander seed than in the control bread. In the case of crude fat and crude fiber, bread added with seed was the highest. The water holding capacity was highest in the bread when 3% of Coriander seed was added. With the increased addition of the Coriander flour, the water holding capacity was lower in the bread in which leaf and seed were added. The loaf weight of bread added with Coriander leaf was increased compared to the control bread and the bread added with Coriander seed. With the increase of the amount of leaf and seed, loaf weight of bread had a tendency to be higher. The loaf volume of bread added with seed was the heighest, followed by control bread and bread added with leaf in order. The color value of bread when Coriander leaf was added had lower values of 1ightness and redness, and higher value of yellowness than those of the control bread. According to the amount added, there was a significant difference in the value of lightness. In the case of bread added with seed, the color value had lower value of lightness and higher values of redness and yellowness than those of the control bread. In the texture characteristics by mechanical examination, the hardness of the bread generally tended to decrease when Coriander was added. Springiness was the highest in the control bread and it was decreased in the bread added with seed and the bread added with leaf in that order. But, the ratio of Coriander added didn`t make a significant difference. Cohesiveness, gumminess and chewiness of bread were, when added with Coriander, generally lower than those of the control bread. Cohesiveness was significantly lower when seed was added to the bread at 5% level. Gumminess and chewiness of it were the lowest when added with Coriander leaf at 5% level. In the results of the sensory evaluation, the bread in which Coriander seed at 3% level was added showed the highest preference in regards to the flavor, taste and mouth feel. The control bread in regards to color and the bread in which 3% of leaf was added in regards to crumb texture attained the best preference respectively. The best result for overall preference showed when Coriander seed at 3% level was added to the bread,
