The suwey on the consumption pattern of Korean traditional soy sauce and commercial soy sauce was performed. 55.8 percentage of surveyed house makes Korean traditional soy sauce domestically, But its frequency in actual use is lower than commercial soy sauce. The use of Korean traditional soy sauce and commercial soy sauce was different depending on the kinds of food. Korean traditional soy sauce is mainly used for kinds of soup, and commercial soy sauce is predominantly used for hard-boiled foods and Chapchae. Korean traditional soy sauce is known as our typical fermented food and has special flavor. But its main factors of special flavor were not well established yet. So the authors have investigated the main components of Korean traditional soy sauce for its typical taste. Five samples o$.$ere selected from'Kyung-ln'area. The sensory charac teristics of Korean traditional soy sauce itself were very different with that of cooked food added with Korean traditional soy sauce. The hard-boiled mackerel cooked with commercial soy sauce was prefered than Korean traditional soy sauce. And soups and seasoned vegetables cooked with Korean traditional soy sauce were profered. By stepwiEe regression analysis and correlation analysis, sensory overall acceptability mainly depends on specific gravity, salt content and amino nitrogen content (R'=0.94). And total nitrogen content was highly coirelated with overall acceptability (r=0.91).

To investigate the main components of Korean traditional soy sauce for its typical taste, we compare the physicochemical properties of Korean traditional soy sauce and commercial soy sauce. The physicochemical analysis revealed that each components showed significant difference between Korean traditional soy sauce and commercial soy sauce. The significant characters for discrimination between Korean traditional soy sauce and commercial soy sauce were salt content, ammonia nitrogen content and total acidity (R$^2$=0.99). The components of Korean traditional soy sauce divided into 3 clusters, and each group is characterized as formol nitrogen, salt and total nitrogen content by cluster analysis. Main amino acids of Korean traditional soy sauce were alanine, glutamic acid, leucine and valine.

This study examined ways to improve the functional properties of commercial soy sauce using gelatin hydrolysates from the refiner discharge of Alaska pollock, Theragra chalcogramma. The total nitrogen content and pH of gelatin sauce prepared by dissolving the second-step gelatin hydrolysates (15 g), salt (20 g), sugar (5 g), glucose (2.5 g), inosine monophosphate (IMP) (0.5 g), black pepper (0.1 g), caramel powder (0.1 g), ginger powder (0.05 g), garlic powder (0.05 g), vinegar (3 mL), and fructose (3 mL) in water(100 mL) were 1.71% and 5.35, respectively. The results of a sensory evaluation indicated that when preparing blended soy sauce, the optimal blending ratio of gelatin sauce to commercial soy sauce was 20:80 (v/v). Because the total nitrogen content and pH of the blended soy sauce were 1.52% and 5.31, respectively, the blended soy sauce could be sold as a soy sauce. The oxidative property of the blended soy sauce was similar to that of 20 mM ascorbic acid, and its angiotensin-converting enzyme (ACE) -inhibiting activity was 1.5 mg/mL. The results suggest that the antioxidative and ACE-inhibiting activities of commercial soy sauce can be improved by blending gelatin sauce (20) with commercial soy sauce (80). The total amino acid content of the blended soy sauce was 9,107.3 mg/mL, which was higher than that (8,992.4 mg/100 mL) of commercial soy sauce. However, the taste value of the blended soy sauce was 415.8, which was lower than that (431.2) of commercial soy sauce.

Purpose: Physicochemical and microbiological qualities were investigated to compare quality characteristics of traditional with commercial soy sauce (Ganjang). Methods: Nineteen traditional products were collected from six provinces and three commercial products were purchased in domestic markets. The proximate composition, inorganic substance contents, viable bacteria, and chromaticity of the soy sauces were measured. Results: Although concentrations of crude fat and protein were not significantly different between traditional and commercial Ganjang, the moisture concentration of commercial soy sauce was significantly higher than in traditional Ganjang (p<0.05). However, the amount of ash in commercial soy sauce was significantly lower than in traditional Ganjang (p<0.05). Total nitrogen concentrations of traditional and commercial Ganjang were 0.50-1.59% and 0.86-1.26%, respectively. Concentrations of Na, Mg, K, Ca, Li, B, Fe, and Sr in traditional Ganjang were significantly higher than in the commercial products (p<0.05). The number of total bacteria in traditional and commercial Ganjang were $3.3{\times}10^1-6.4{\times}10^7CFU/mL$ and $5.5{\times}10^1-2.0{\times}10^3CFU/mL$, respectively. Bacillus cereus were below 10,000 CFU/mL in all samples, and Staphylococcus aureus was not detected. Fungi was not detected in 13 samples of traditional Ganjang and the three samples of commercial soy sauce. Although lightness, redness, and yellowness were not significantly different among the Ganjang, G10 was had the highest values (p<0.05). Conclusion: This research provided information about the quality characteristics of traditional and commercial Ganjang.

This study was conducted to evaluate the chemical hazards of 74 kinds of commercial anchovy fish sauce in Korea by measuring their biogenic amine content. The biogenic amines detected in commercial anchovy fish sauce were tryptamine, putrescine, cadaverine, tyramine, spermidine, spermine, and histamine. Among them, histamine content was the highest with an average of 1,439.62±812.62 mg/kg. Excessive intake of histamine could result in chemical food poisoning characterized by high blood pressure, headache, and diarrhea. Accordingly, by simulating histamine exposure (repetition=10,000 times) based on the daily intake of 0.969 g of domestic anchovy fish sauce, we found that the estimated average histamine exposure was 24.49±55.48 ㎍/kg bw/day and that the margins of exposure (MOE) value were 139.18 at 1% and 66,141.07 at 95% of 10,000 simulations (9,500 times). As such, it was confirmed that 9,500 out of 10,000 simulations of MOE analysis significantly exceeded MOE 10. Therefore, the risk of exposure to histamine from ingestion of commercial anchovy fish sauce is approximately very low.

This study was conducted to evaluate the changes in porcine serum albumin (PSA), a major allergen, which occur when raw pork ham is marinated with kiwi or pineapple juice, and/or when the ham is pan broiled at $300^{\circ}C$ for 4 min after marination. In this study, raw pork ham was soaked for 4 h or 8 h in marinades containing commercial marinating sauce only, commercial marinating sauce and 7% kiwi juice, or commercial marinating sauce and 7% pineapple juice. When the meat was marinated and then pan-broiled, pork ham meat protein was significantly denatured and hydrolyzed, and the level of PSA in the meat was significantly reduced. The PSA contents of pork broiled without marination, pork that had been marinated in commercial marinating sauce alone, pork that had been marinated in commercial marinating sauce with kiwi juice, and pork that had been marinated in commercial marinating sauce with pineapple juice, were 95.4, 43.3, 14.3, and 5.4 ng/mL, respectively (p<0.05). Marinating with pineapple juice was more effective than marinating with kiwi juice; and marination for 8 h was more effective than marinating for 4 h. These results indicate that the level of PSA in pork ham is effectively reduced, when the meat is first marinated in sauces that contain kiwi or pineapple extracts for 8 h, rather than 4 h, and then cooked. Further study is needed to determine whether marinated pork meat reduces allergenicity in vivo, as well.

Alkali treatment following acidic hydrolysis (ATAH) is a commonly used practice for reducing the levels of monochloropropanediol in commercial Korean soy sauce. This study investigated the chemical compounds produced in commercial Korean soy sauce made by ATAB. The levels of amino-N, total acidity, pH, salinity and Brix of the soy sauce were 6.66%, 2.52%, 19.81%, 4.57 and 35.01, respectively. The major fatty acids were C18:2n-6, C16:0, Cl8:ln-9 and C18:3n-6. The concentration of polyunsaturated fatty acids were especially high, with of C18:2n-6 (49.8%) being the highest followed by C18:3n-6 (3.8%) and C18:3n-3 (2.4%) in that order. Among the non-volatile organic acids, the concentration of levulinic acid (1,206.28 mg/100 g) was the highest, while the taste value of citric acid was the highest. Among the ATP related compounds, IMP concentration (31.19 mg/100 g) was highest followed by AMP, hypoxanthine and GMP in that order. The concentrations of free and total amino acids in soy sauce were 6,136.94 mg/100 g and 8,702.76 mg/100 g, respectively. On the other hand, the taste value of glutamic acid, a major amino acid flavor determinant in soy sauce, was highest of all the amino acids, which is desirable since most free amino acids such as methionine, histidine and phenylalanine have a bitter taste that detracts from the flavor of soy sauce.

The quality of commercial sauce products was evaluated through pH, soluble solid content, salinity, water activity and microbial analyses. The pH of sauces was 2.38~5.30, soluble solids were between 6.03 and 71.67, and distributions of salt were 0.23~5.00% in 32 commercial sauce products. In addition, water activity of vinegar red pepper sauce and spicy soft tofu stew stock were determined 0.773 and 0.988, respectively. Yeast, mold, Staphylococcus aureus, E. coli and coliform were not detected in any sauces. Higher level of total viable cells (TVC) resulted in pH over 4.2. TVC of shelf-stable sauces was 1.0~3.6 log CFU/g. TVC of seven sauce products was classified as non-potentially hazardous foods by temperature controlled for safety standard (TCS), even though levels were over acceptable guidelines of the USDA (3 log CFU/g). These results indicate that the standard and classification of commercial sauce products should be modified and controlled strictly.

Gas formation, and container swelling and explosion during the distribution of commercial soy sauce is an important problem to be solved. Six yeasts were isolated from soy sauce returned because of container swelling. Three isolates (SS-1, SS-2, SP-1) formed film on soy sauce while others did not. Five isolates(SS-1, SS-2, SS-4, SP-1, SP-2) actively fermented soy sauce to produce gas and all were identified as Zygosaccharomyces rouxii, and one other isolate (SS-3) fermented soy sauce very weakly and was identified as Candida globosa.

Soy sauce, a basic ingredient in Asian cuisine, is made of fermented soybeans, salt, water, and barley or wheat flour. The sensory characteristics of soy sauce are not only determined through its main ingredients but also by various flavor compounds produced during the fermentation process. This study was conducted to identify the sensory attributes of five different commercial soy sauce samples that differ in Meju types (traditional Meju or modified Meju) and usage types. Thirty three sensory attributes, including appearance (1), odor (16), flavor (14), and mouthfeel (2) attributes, were generated and evaluated by eight trained panelists. The collected data were analyzed by analysis of variance and principal component analysis. There were significant differences in the intensities of all sensory attributes among the soy sauce samples. Soy sauce made with traditional Meju had high intensity of fermented fish, beany, musty odors and salt, Cheonggukjang, fermented fish flavors. Whereas two soy sauces made with modified Meju were strong in alcohol, sweet, Doenjang, roasted soybean flavors. Two soy sauces for soup made with modified Meju had medium levels of briny, sulfury, fermented odors and bitter, chemical flavors and biting mouthfeel characteristic.
