This study was carried out to evaluate the quality characteristics of the fermented pork with soy sauce, red pepper paste and soybean paste. The ham of pork were cut to cube (7 × 10 × 2 cm³) and Korea traditional seasonings such as soy sauce (T1), red pepper paste (T2), soybean paste (T3) were seasoned by the proportions of meat to seasonings (1:1), respectively. The pH of fermented pork with soybean paste seasoning were significantly higher compared to those for fermented pork with soy sauce and red pepper paste seasoning at 1 and 28 days of storage, but were significantly lower at 14 days of storage. The water-holding capacity of fermented pork with soy sauce seasoning were significantly higher compared to those for fermented pork with red pepper and soybean paste seasoning at 28 days of storage. The surface meat L* values of fermented pork with soybean paste seasoning were significantly higher compared to those for fermented pork with soy sauce and red pepper paste seasoning, but a* and b* values of fermented pork with red pepper paste seasoning significantly higher. The volatile basic nitrogen (VBN) of fermented pork with soybean paste seasoning were significantly lower compared to those for fermented pork with soy sauce seasoning at 1 and 28 days of storage. The shear force and thiobarbituric acid reactive substances (TBARS) of fermented pork with soybean paste seasoning were significantly lower compared to those for fermented pork with soy sauce and red pepper paste seasoning. The total plate counts of fermented pork with soybean paste seasoning were significantly higher compared to those for fermented pork with soy sauce and red pepper paste seasoning at 14 days of storage, but were significantly lower at 28 days of storage. The Escherichia coli of fermented pork with soy sauce and soybean paste seasoning were significantly lower compared to those for fermented pork with red pepper paste seasoning at 1 day of storage. The Lactobacilli spp. of fermented pork with red pepper paste seasoning were significantly lower compared to those for fermented pork with soy sauce and soybean paste seasoning.

Methods of adding barley malt as source of carbohydrates and enzymes in the production of kanjang in order to improve it's tastes and qualities were investigated. Soybean meju, soybean-malt meju and soybean meju cummalt was mashed with 20% salt brine in the ratio of 1:3 respectively, matured and analyzed the chemical compositions of the soy sauce mash samples for 150 days of maturing. Organoleptic evaluations for the matured soy sauce samples were done. The higher total nitrogen, TCA soluble nitrogen, O.D. at 500 nm, pure extract and lactic acid content could be observed with the soy sauce mash made of soybean-malt meju than those of contrast one from the beginning of the mashing throughout to the whole maturing period of 150 days. The higher the content of malt in the soybean-malt meju, the higher those content in the mash. But the lower content of those compositions in the soy sauce mash made of soybean meju cum malt than those in the contrast was found. The highest scores in all the sensory characteristics including 7.56 points, which were significantly different from that of contrast soy sauce at 5% level, in overall palatability were obtained by the soy sauce made of soybean-malt meju added with 30% malt in the organoleptic evaluations.

The study was carried out to determine the effect of storage property and qualities on soybean sauce and paste by adding different amount of pyroligneous liquor obtained by sujpercritical fluid extraction(SFE). Purified pyroligneous liquor obtained by SFE at 4$0^{\circ}C$/110 bar contained p-cresol, o-cresol and m-cresol food sterilizers, but no toxic substances such as tar, scorched, furfuraland and monophenol. Thus pyroligneous liquor was considered to be suitable as natural food preservative. In case of soybean sauce, pyroligneous liquor was tested to determine the potential of natual food preservative to prevent flim formation on soybean ksauce 15days at 3$0^{\circ}C$. Increasing amounts of purified pyroligneous liquor added to soybean sauce prevented film forming yeasts. In case of paste, pyroligneous liquor was tested to determine the potential of natural food preservative to inhibit browning on paste 60 days at 3$0^{\circ}C$. Purified pyroligneous liquor added to paste inhibited brown pigment. As a result, purified pyroligneous liquor offered a promising way of improving the quality and storage property of soybean sauce and paste.

Soybean varieties derived from Korea are classified into four groups on the basis of their food types such as soybeans for vegetable, sprout, sauce and paste and soybeans with colored seed coat. This study was carried out to know the differences in storage protein concentrations among these four groups. There were differences in storage protein concentrations among four groups. In 7S protein, the $\alpha$'-and $\alpha$-subunit concentrations did not vary among four groups, while a $\beta$-subunit concentration greatly varied. 7S protein concentration was the highest(40.6%) in soybean for sauce and paste and the lowest(37.7%) in soybean for vegetable, while 11S protein concentration was the highest (62.3%) in soybean for vegetable and the lowest (59.4%) in soybean for sauce and paste. In view of the fact that 11S protein has much higher sulfur containing amino acids than 7S protein, it was shown the soybeans for vegetable may have higher nutrition value than other groups.

The effects of types of soybean sauceI(SS) and additives for soybean sauce(AS)on the antioxidative activity was studied. The values of peroxides(POV) and thiobarbituric acid (TBA) were monitored under the oxidation systems of linoleic acid or ground cooked meat. Among 10 types of SS including Korean treditional SS, Koran M company's raw SS, Korean koikuchi, Korean acid hydorlyzed SS, Korean mixed SS, Korean decolorized SS, Japanese tamari, koikuchi, usuguchi, and Japanese white SS, three SS types of Japaness tammari, koikuchi and Koran raw SS were found to have the most strong antioxiative activity. However, various as such as monosodium glutamate, caramel, fructose syrup, malt syrup and paraoxybenzoic acid (POBA) were appeared to accerlerate oxidation. Possibly an important antioxidative cahracteristics was due to its higher concentration of nitrogen and melanoidin.

This study was conducted to investigate 1he quality characteristics of 1he soybean anchovy sauces added with medicinal herbs, Saururu chinensis Baill. and Houttuynia cordata Thunb. and fermented for 4 months. The total nitrogen content of 1he soybean anchovy sauce increased with the fermentation time showing the highest values in the sauce with Houttuynia cordata Thunb.. The contents of total sugar and reduced sugar were high in the order of the sauces with Houttuynia cordata Thunb.(sauce T), with Saururu chinensis Baill.(sauce B), and control. The content of salt decreased much more in the sauces with medicinal herbs. After 4 months of fermentation, pH was lowered from 5.86 to 5.27 in control, to 5.38 and 5.54 in sauce B and sauce T, respectively. Generally the total aerobic bacterial count increased until 3 months of fermentation and then decreased, and the addition of medicinal hems reduced the count especially showing apparent reduction in the sauce T. During the fermentation, total protease activity generally increased with the highest value in the sauce T. In the changes of nucleotides and their related compounds, the contents of AMP, ADP, and ATP were increased and hypoxanthine decreased during the fermentation, and IMP produced after 3 months. The soybean anchovy sauce B had 1he highest IMP and the lowest hypoxanthine after 4 months. The content of total amino acids increased showing 177.1 mg% and 134.7 mg% in the sauce B and sauce T respectively compared with 171.2 mg% of control. The contents of glutamic acid and aspartic acid were 29.2 mg% in sauce B and 34.3 mg% in sauce T, which were higher compared with 25.9 mg% of control. The fermented soybean anchovy sauce had 1he functionality of ACE inhibition with 70.5% (control), 72.5% (sauce B) and 81.6% (sauce T). In the results of sensory evaluation, the sance T scored the highest and the sauce B was preferred to control.

To develop a method appropriate for mass production in a factory, we manufactured soy sauce with Bacillus species SSA3-2M1 and fused ST723-F31 at $30^{\circ}C$ with aeration of 1/3 vvm for 40 days. The flavor components extracted from the manufactured soy sauce were fractionated to neutral, acidic, basic and phenolic fraction and identified by GC-mass. Among the 60 kinds of identified flavor components, 16 and 23 components were detected in traditional Korean soy sauce and soybean paste, respectively. There were three peak regions that smelled like soy sauce with the GC sniffing test of flavor components and 2, 6-dimethyl pyrazine, benzaldehyde, 2-methoxy phenol, phenol and benzeneethanol which were identified as character impact compounds of traditional Korean soy sauce and soybean paste were identified in the region that smelled like soy sauce. It is therefore considered possible to achieve mass production of soy sauce with standard quality by Bacillus species SSA3-2M1 and fused ST723-F31 in the factory.

This study was conducted to develop soybean paste sauce with walnuts and sesame seeds and apply it to cooked spinach to examine the applicability of the sauce. Two factors of soybean paste sauce, soybean paste and glutinous rice paste, were need to decide the quantity of the ingredients. Nine soybean paste sauces were produced with various compounding ratio of soybean paste and glutinous rice paste, and color, viscosity and sensory evaluations were performed. Sensory evaluations were measured by 7-point Likert scale. Color($4.08{\pm}1.22$), taste($4.72{\pm}1.24$), viscosity($4.96{\pm}1.39$) and overall quality($4.24{\pm}1.51$) of the sample(soybean paste 400 g, glutinous rice paste 400 g) got the highest scores. Therefore, the sample(soybean paste 400 g, glutinous rice paste 400 g) was applied to cooked spinach. Cooked spinach using developed sauce and cooked spinach using general soybean paste were prepared and performed sensory evaluation. As a result, all sensory items score of cooked spinach using developed sauce were higher than that using general soybean paste. Especially, taste($4.96{\pm}1.15$) and overall quality($0{\pm}1.16$) of cooked spinach using developed sauce were significantly higher than taste($4.38{\pm}1.53$) and overall quality($3.56{\pm}1.53$) of cooked spinach using commercial soybean paste(p<0.05). Consequently, the applicability of soybean paste sauce using natural seeds was confirmed.
