In this study, we investigated e kinds and names of side dishes along with their recipes and ingredients occuring in Korean cookbooks published before the 17th century. The side dishes were classified 79 kinds of Guk, 23 kinds of Jjim and Seon, 15 kinds of Gui, 3 kinds of Jeon, 7 kinds of Nureumi, 3 kinds of Bokkeum, 30 kinds of Chae, 11 kinds of Hoe, 7 kinds of Jwaban, 6 kinds of Mareunchan, 12 kinds of Pyeonyuk and 5 kinds of Jeonyak, Jokpyeon and Sundae. The earliest records were found on Guk, Jjim, Jwaban, Po and Pyeonyuk Gui, Namul and Hoe were recorded after the 1500's and Nureumi, Jeon, Jeonyak, Jokpyeon and Sundae were developed relatively late in the late 17th century. As to the kinds of side dishes, Guk was the most common. Guks cooked before the 17th century used different recipes and more types of ingredients than today, including some that are not used today. For Jjim, various seasonings were added to main ingredients such as poultry, meat, seafood and vegetable. Most of the records found for Jjim used chicken as the main ingredient. Gui was recorded as Jeok or Gui and there weren't many ingredients for Gui before the 17th century. Gui was usually seasoned with salt or soy bean sauce and broiled after applying oil. Vegetables were broiled after a applying flour-based sauce. The Jeon cooked at that time was different from the one that is cooked today in that cow organs or sparrows were soaked in oily soy bean sauce before being stewed. Nureumi, which was popular in the 17th century, but rarely made today, was a recipe consisting of adding a flour or starch-based sauce to stewed or broiled main ingredients. Chae was a side dish prepared with edible plants, tree sprouts or leaves. Chaes like Donga and Doraji were colored with Mandrami or Muroo. Hoe was a boiled Hoe and served after boiling seafood. Jwaban was cooked by applying oil to and then broiling sparrows, dudeok, and mushrooms that had been seasoned and dried. For dried Chans, beef or fish was thin-sliced, seasoned and dried or sea tangle was broiled with pine nuts juice. There are some recipes from the 17th century whose names are gone or the recipes or ingredients have changed. Thus we must to try to rebuild three recipes and develop recipes using our own foods of today.

Meju is a traditional Korean fermented soy product used as a key element for soy sauce and doenjang. Bacilli with antimicrobial activity were isolated from meju prepared by traditional methods at Sunchang county, Jeollabukdo, Korea. Six isolates were identified as Bacillus amyloliquefaciens by recA gene sequencing and RAPD-PCR. One isolate, B. amyloliquefaciens MJ5-41, showed the strongest fibrinolytic activity. A 27 kDa active fibrinolytic enzyme, AprE5-41, was purified from the culture supernatant of MJ5-41 grown on LB by chromatographic methods. The optimum pH and temperature for purified AprE5-41 were 7.0 and $45^{\circ}C$, respectively. AprE5-41 quickly degraded $A{\alpha}$ and $B{\beta}$ chains but not the ${\gamma}$-chain of fibrinogen. AprE5-41 exhibited the highest specificity for N-succinyl-Ala-Ala-Pro-Phe p-nitroanilide, a known substrate for ${\alpha}$-chymotrypsin, cathepsin G, and subtilisin BPN'. The structural gene, aprE5-41, was cloned by PCR and successfully expressed in B. subtilis.

Soy sauce is a traditional fermented seasoning in several oriental countries, such as Korea and Japan, and recently it has been reported to have biological activities. In Korean soy sauce, soybeans and wheat are the two main raw materials. Polysaccharides that originate from the cell wall of soybeans are resistant to enzymatic hydrolysis. These polysaccharides remain in the soy sauce even after fermentation and are termed Kanjang polysaccharides (KPS). In this study, polysaccharides were obtained from dialysate of different soy sauces labeled as A~T and manufactured by fermentation or the acid-hydrolyzate method. We investigated anti-inflammatory activities by examining the effects of these KPS on proinflammatory cytokine release and mRNA expression in mast cells. Histamine and ${\beta}$-hexosaminidase release were strongly decreased by the KPS treatment in RBL-2H3 cells. Treatment with KPS clearly reduced mRNA expression and the release of the proinflammatory cytokines interleukin (IL)-6, IL-8, and tumor necrosis factor-alpha (TNF-${\alpha}$) in PMACI-stimulated HMC-1 cells. In particular, KPS derived from fermented Kanjang products showed a significant anti-inflammation effect on mast cells compared to the acid-hydrolyzed Kanjang products. This study suggests that KPS appear to be effective in suppressing allergic inflammatory reactions.

Asparagus have anti-cancer, antioxidant, and anti-inflammatory properties. Since the high functionality of Korean traditional sauces was discovered, various studies have been conducted using asparagus. In this study, the antioxidant activity of traditional sauces containing asparagus was confirmed. The antioxidant capacity of asparagus was independent of the concentration and showed the highest activity at 70 mg/ml. For instance, concerning Meju containing asparagus, high antioxidant activity was observed in water and ethyl acetate extracts; the total polyphenol content was equivalent to 1.4 mg/g and 0.7 mg/g of tannic acid in the water and ethyl acetate fractions respectively. The DPPH and ABTS radical scavenging activities were 27.6% and 9.04%, respectively, in the water layer, and 10.7% and 52.4%, respectively, in the ethyl acetate layer. Additionally, the antioxidant activity of asparagus-containing traditional sauces was measured using 95% ethanol extracts; soy sauce showed the highest activity, retained in a wide range of concentrations.

This study was conducted to optimize processing of functional seasoning sauce for instant noodles (SSIN) using response surface methodology (RSM), and to compare the functional properties of commercial SSIN. Central composite designs were adopted in the SSIN processing for ingredient formula optimization. Concentrations of sea tangle ($X_1$), traditional soy sauce ($X_2$), yeast extract ($X_3$) and Ecklonia cava extract (ECE) ($X_4$) were chosen as independent variables. The dependent variables were glutamic acid content ($Y_1$), score of sensory evaluation ($Y_2$), and antioxidative activity ($Y_3$). We found the optimal conditions to be $X_1$=3.91%, $X_2$=20.57%, $X_3$=3.04% and $X_4$=3.78%. The predicted values of the multiple response optimal conditions were $Y_1$=124.0 mg/100 g, $Y_2$=7.6 and $Y_3$=1.95. The antioxidative activity (PF, PF=oil induction period with sauce/oil induction period with distilled water) and ACE inhibitory activity of ECE-added SSIN were 1.98 and 29.0%, respectively, which were significantly higher than those of commercial SSIN (1.09 and 4.4%, respectively).

Changes of Microflora, enzyme activity, and contents of several taste compounds in traditional Kanjang(Korean Soy Sauce) with the variation of fermentation jars and Meju(fermented soybean brick)concentration were studied. Substitution possibilities of clay jar with glass jar and improvement possibilities of taste and nutritional value with increased Meju concentration were examined. (1) Aerobic bacteria and lactic acid bacteria were enumerated during fermentation and ripening period. But yeast and molds were hardly isolated. The number of viable cells showed small changes during fermentation and ripening period. (2) Isolated Aerobic bacteria were identified as Bacillus subtilis, Bacillus lichenformis, and lactic acid bacteria were identified as Lactlbacillus lactis lactis and lactobacillus brevis. (3) The activities of $\alpha$-amylase and $\beta$-amylase increased during fermentation period, but did not show any trend by fermentation jars or Meju concentrations. Protense activity showed small difference among four samples, and increased during the fermentation period.
