In this study, we investigated the quality characteristics of Korean soybean paste, Doenjang, fermented for 6 weeks at room temperature with the addition of 0, 10, 20 and 30% garlic. Samples were analyzed in one-week intervals. The lightness decreased in all samples as the fermentation period and garlic concentration increased. Yellow index decreased in weeks 5~6 compared with weeks 0-1, for which the values were lower for the garlic-added Doenjang than the control. The pH increased, greatly reducung the acidity in week 1 compared with week 0. Significant differences in the pH and acidity were not observed among the sample groups. Amino type nitrogen contents increased continuously up to weeks 5, displaying no significant differences among the sample groups at weeks 5 and 6. In addition, reduction in the sugar content increased depending on the fermentation period. It increased in all sample groups by about 2.5 times after 6 weeks compared with the initial levels. Isoflavone content was also reduced generally depending on the fermentation period. In the early fermentation periods, the aglycone contents were the higher than the glycosides, while the glycoside contents increased over the fermentation period. The presence of Bacillus was not significantly different among the garlic added groups, but yeast was lower in the Doenjang with high garlic content.

This study was conducted to standardize ingredient ratios of wooung kimchi. The ingredient ratios of model wooung kimchiwere determined by the survey in Pusan and Kyungnam province and using the literatures including cooking books. Several kinds of wooung kimchi were prepared by adjusting the ingredient ratios fo the model wooung kimchi within standard deviation. The wooung kimchi with different ingredient ratios were fermented for 6 days at 15$^{\circ}C$. The chemical, microbial and sensory properties of the wooung kimchi were investigated. There was little change in pH but the counts of lactic acid bacteria were decreased, as the ratio of pickled anchovy juice became high. The wooung kimchi adding 9.4% pickled anchovy juice obtained high score in appearance and overall acceptability. The counts of lactic acid bacteria were increased in wooung kimchi adding 5% red pepper powder, and there was obtained better result in appearance, texture and overall acceptability than the other groups. The activity, reducing sugar and counts of lactic acid bacteria were increased, as the ratio of glutinous rice paste became high. The wooung kimchi including 6% glutinous rice paste showed the highest score in overall acceptability. The fermentation process of wooung kimchi accelerated, as the ratio of garlic became high. The wooung kimchi adding 3% garlic showed good appearance and acceptability. In addition to these, the addition of 1.3% ginger ehhanced the appearance, texture and overall acceptability fermented anchovy juice, 5.0% red pepper powder, 6.0% glutinous rice paste, 3.0% crushed garlic and 1.3% crushed ginger.

Saccharomyces cerevisiae and Zygosaccharomyces rouxii are known to produce alcohol in gochujang. To reduce alcohol production, garlic and chives were applied to gochujang solution to find their inhibitory effect on S. cerevisiae and Z. rouxii. The 70% ethanol extract of garlic and chives showed significant inhibition activity against S. cerevisiae and Z. rouxii, showing growth inhibition zone of 14.00±0.00~25.33±0.58 mm by disc diffusion method. In addition, the addition of 70% ethanol extract of garlic and chives in 10% gochujang solution spiked with S. cerevisiae and Z. rouxii reduced the numbers of total aerobic bacteria (below 7 Log CFU/g) and yeast (below 4 Log CFU/g), alcohol content (below 0.30%), respectively. In conclusion, the addition of garlic ethanol (70%) extract or chives ethanol (70%) extract to gochujang inhibited the growth of S. cerevisiae and Z. rouxii, resulting in reduced alcohol content in gochujang. For further study, it is necessary to conduct food application experiments by using real gochujang paste.

This study was conducted to investigate the quality characteristics of red pepper paste (RPP) added with garlic during aging at $10^{\circ}C$ for 56 days. RPP was evaluated for pH, acidity, free sugar contents, Hunter's color values, flavor patterns, and sensory characteristics. The initial pH and acidity of the RPP with garlic were 5.07~5.18 and 0.33~0.35%, respectively. The pH of RPP increased as the amount of garlic added increased, whereas the acidity decreased. The pH and total acidity changed gradually until day 28, after which they changed rapidly. The initial fructose and glucose contents of the RPP with garlic decreased to 2.32~2.41% and 1.94~2.09%, respectively. The fructose and glucose contents further decreased gradually to 1.81~1.94% and 1.54~1.71%, respectively, during aging. The Hunter's L- and b-values of the RPP increased, whereas the a-value decreased as the amount of garlic added increased. The flavor patterns of the RPP with garlic noticeably differed from those of the control RPP during aging. Sensory evaluation indicated that garlic could enhance the overall flavor characteristics of RPP.

Though traditional seasonings are widely used in many dishes, however, no attention has been paid to the investigation of their effects on quality characteristics of food products. The present investigation was undertaken to study the effects of incorporating several traditional seasonings including doenjang (fermented soybean paste), gochu-jang (red pepper paste), fresh medium-hot, and hot peppers, and fresh garlic on the lipid oxidation, cholesterol content and sensory characteristics of fermented sausages. Six fermented sausage treatments (5 with 1% (w/w) each test seasoning and 1 without added test seasoning (control) were prepared. The addition of seasonings generally had beneficial effects on the improvement of fermented sausage's quality however the effects differed depending on the each type of seasonings added. Significant lower pH values were found in all fermented sausages made with the seasonings while, lower levels of lipid oxidation were found in the treatments with hot peppers and garlic as compared with the control (p<0.05). The treatment with seasonings did not cause color or texture defects in the products whereas the sausages made with gochu-jang had significantly higher Commission International de $l^{\prime}Eclairagea^{\ast}$ (redness) value in comparison with the control. Noticeably, incorporating doenjang, medium-hot peppers, hot peppers and garlic resulted in reduction of 26.50, 32.54, 47.04, and 48.54 mg cholesterol/100 g samples, respectively (p<0.05). Higher scores for the sensory traits such as aroma, taste, color and acceptability were also given for the sausages made with seasonings. The current work demonstrates that the test seasonings represent potentially natural ingredients to be used for producing healthier fermented sausages.

In this paper, the differences between Korean and Japanese ways of seasonings are studied. The main results are summarized as follows: (1) Shouyu and Miso which are Japanese equivalents of soy sauce and bean paste of Korean foods are used in variety of different seasonings with some other ingredients while Korean counter parts are used only to add salty tastes. (2) Shouyu and Miso lose their flavors after considerable time of heating, while Korean soy sauce and bean pastes increase their tastes after heating. (3) Mirin adds sweety taste and glaze and Sake makes food soft or hard according to the moment of being added during cooking. (4) In Korean foods soy sauce, bean paste and red pepper paste are on the basis of tastes, Dashi is used in almost every Japanese food. (5) Seasoned vegetables of Korean food are prepared only with spices of green onion, garlic and sesame oil while seasoned fishes or vegetables are mixed with Shoyu or salt and vinegar in Japanese food. (6) In making Zorim, Korean traditional sauces are added from the beginning of heating. But in making Nimono, sugar, salt, vinegar, Shoyu and artificial taste are added in order during heating. (7) In grilling, main food for grilling in Korea is meat, which is prepared with a variety of spices such as soy sauce or/and red pepper pastes, garlic, green onion, sesame oil, sesame powder, pepper and sugar while mainly fishes are grilled with salt, occasionally with Shoyu or Miso in Japanese food. (8) Pan frying fishes are taken with soy sauce with vinegar in Korea but Tepura are eaten with Tentsuyu in Japan.
