Traditional and commercial soy sauces used for seasoning soups and cooked mungbean sprouts were evaluated for consumer preference. Table salt was included in sensory tests, because the consumer commonly used it for seasoning soups. Triangle tests with 30 trained panelists were used to evaluate differences between two soy sauces, and 9 point hedonic scale tests with 100 consumer panelists to evaluate the consumer preference. Taste of sea mustard, Chinese radish and dried pollack soups seasoned with the traditional soy sauce, commercial soy sauce for soup and table salt was significantly different. The consumer panel indicated that the commercial soy sauce for soup was most preferred and the traditional soy sauce least preferred. Taste of cooked mungbean sprouts seasoned with two sauces, prepared with either traditional or commercial soy sauces, was significantly different from each other, but the consumer panel could not detect the difference in preference.

Shrimp in seasoned soy sauce (S-SS) is a popular seafood product in Korea, but it could be potentially hazardous; thus, this study was conducted to investigate its safety. Commercial S-SS were collected and analyzed for pH, volatile basic nitrogen (VBN), hygenic indicator microorganisms (viable cell count, coliforms, and Escherichia coli), food poisoning bacteria (Staphylococcus aureus, Vibrio parahaemolyticus, and Listeria monocytogenes), preservatives (dehydroacetic acid, sorbic acid, benzoic acid, and its salt, parahydroxybenzoate), tar colorants, and sensory properties. Domestic and foreign standards were also investigated for S-SS. Commercial S-SS ranged from to 6.2-7.3 for pH, 13.7-39.1 mg/100 g for VBN, and 4.6-6.9 log CFU/g for viable cells. The coliforms and E. coli of commercial S-SS were from ND to 3.4 log CFU/g and negative, respectively. Food poisoning bacteria, preservatives, and tar colorants were not detected in commercial S-SS. Only the coliform count and presence of E. coli in commercial S-SS exceeded the set standards of vietnam, while all items were within domestic and foreign standards.

Purpose: This study measured the ethyl carbamate (EC) content in commercial and home-made soy sauce and examined the effects of cooking methods, such as boiling and pan-frying, on the EC content. Methods: A total of 20 soy sauce samples including 14 home-made and 6 commercial products were analyzed according to the AOAC official method with some modifications. To simulate conventional boiling, soy sauce containing EC ($14.59{\mu}g/kg$) was heated to $100^{\circ}C$ for four different times: 10, 20, 30, or 40 min. Pan-frying was conducted for 4 min at $170^{\circ}C$. Results: EC was not detected in any of the homemade samples, whereas it was found in the commercial samples, ranging from 2.51 to $14.59{\mu}g/kg$. The concentrations of EC increased gradually with increasing boiling from 14.59 to $26.54{\mu}g/kg$, whereas pan-frying did not affect the EC level in soy sauce. Conclusion: These results indicate that EC is formed by a reaction between the EC precursors during boiling, suggesting that the cooking method of each food should be considered when estimating the dietary exposure to EC.

The purpose of this study was to investigate the sensory characteristics of brown sauce made with different ratios of Jubak. In the brown sauce made from Jubak, the followings showed changes according to the amount of Jubak. The content of crude lipid increased, that of crude protein and moisture decreased, and that of crude ash and reduced sugar increased. Brown sauce made from Jubak contained more reduced sugar than general brown sauce, and the content of reduced sugar increased. pH increased from initial pH 4.32 to 5.42 respectively, and viscosity increased. The "L" value expressing brightness of samples had a tendency to increase with Jubak added. "a" value had a tendency to increase in case of no Jubak added, and "b" value had a tendency to decrease according to the amount of Jubak. In the sensory evaluation, color and flavor decreased and viscosity increased with the amount of Jubak. Overall, it was the highest in 0% Jubak. From the above results, an addition of 25% Jubak to brown sauce is recommended for commercial use.

This study analyzed the quality characteristics of demi-glace sauce with different addition of roux which is usually used as a thickener. The trust level and acceptability for commercial demi-glace sauce were surveyed in order to draw the visual idea and direction for the development of large scale commercial production of demi-glace sauce. Also, the optimal level of salt and roux content in the sauce was determined with various cooking conditions. As the roux content increased, the color became light and the viscosity of the sauce increased while pH, salinity and brix were not affected much by amount of roux. The professional chefs as well as general sensory panel preferred the demi-glace sauce prepared with 9% roux. To sum up, it can be claimed that the optimal conditions established in this study for commercial production of demi-glace sauce ensure the desired quality and economic feasibility.

Alkali treatment following acidic hydrolysis (ATAH) of defatted soybean is currently used to reduce the level of 3-chloropropane-1,2-diol (3-MCPD), a known carcinogen, in commercial Korean soy sauce. 3-MCPD concentrations in commercial soy sauces made by ATAH were compared with those made only by acidic hydrolysis, and products that combine soy sauce made by acid hydrolysis (followed by alkalinization) and enzymatic methods. The four soy sauces made by ATAH had lower 3-MCPD concentrations (below 0.078 ppm) than 4 commercial products (0.147∼0.481 ppm) made only by acidic hydrolysis. On the other hand, 3-MCPD concentrations in 4 commercial products made by combining soy sauces made enzymatically with that made from acid (with alkali treatment)-hydrolyzed soybean protein in varying ratios were in a range of 0.016∼0.053 ppm. The 3-MCPD concentrations in commercial Korean soy sauces, with the exception of 2 of the soy sauces made only by acidic hydrolysis, were lower than allowable limit of 0.3 ppm in Korea. These results demonstrated that currently produced commercial soy sauces on the Korean market hate toxicologically save 3-MCPD concentrations. It is also provides evidence that ATAH is an effective process for reducing 3-MCPD concentrations in commercial soy sauce.
