The effects of high-pressure processing (HPP) treatment on the quality characteristics of low graded Hanwoo beef marinated with five different sauces (soy, fish, fish-soy, soy-fish and fish-soy-meat sauces) obtained from Asian countries were studied. The Hanwoo beef striploins were marinated with the aforementioned sauces (at ratio: 3:1 w/w) for 3 days at $4^{\circ}C$ before they were treated with HPP at 550 MPa for 5 min at $10^{\circ}C$. All the sauces used were equalized to a same salt level of 12.5%, and the samples marinated with a 12.5% brine solution were served as a control. After treating with the HPP, all the samples were stored for further 7 days at $4^{\circ}C$ for analyses. Results revealed that HPP treatments showed some effects on technological quality traits (pH, cooking loss and color) but had no effect on the collagen contents of the marinated beef. Noticeably, the HPP treatment led to the increases in amounts of free amino acids associated with monosodium glutamate-like taste and sweet taste in the samples marinated with fish sauce or soy-fish sauce, fish-soy sauce and fish-soy-meat sauce whereas, it only reduced these amino acids in the samples marinated with soy sauce or control. Furthermore, the total bacteria count in all the marinated beef samples treated with HPP were significantly (p<0.05) lower than those of the non-HPP-treated samples throughout the storage periods. It is concluded that HPP could be applied for enhancing the taste-active compounds production such as free amino acids, and improving the shelflife stability of the marinated beef.

To develope a rapid processing method for fish sauce, processing conditions of fish sauce from sardine waste was investigated. The chopped waste was homogenized and hydrolyzed by commercial proteolytic enzymes such as Complex enzyme-2000($2.18\cdot10^4$ U/g solid) and Alcalase($1.94\cdot10^4$ U/g solid) in a cylindrical vessel with 4 baffles and 6-bladed turbine impeller. Optimal temperature for the case of hydrolysis with Complex enzyme-2000 was 50 and that with Alcalase was $55^{\circ}C$. In both cases, the reasonable pH, amount of water for homo-genization, enzyme concentration and hydrolyzing time were 8.0, $40\%$ (W/W), $3\%$ and 100 min, respectively. Heating of the filtrated hydrolysate for 2 hours at $90^{\circ}C$ with $6\%$ of invert sugar was suitable for pasteurization of the hydrolysate and inactivation of enzymes. Flavor, taste and color of the hydrolysate was improved during the thermal treatment in which the browning reaction products might participate and result in antioxidative and bactericidal effects. Combined use of $0.005\%$ of Caryophylli flos with invert sugar was also effective for the improvement of taste. Yield of the fish sauce based on the total nitrogen in the raw sardine waste was $91.2\~92.3\%$ and $87.2\~87.8\%$ of the total nitrogen in the fish sauce was in the form of amino nitrogen. The pH, salinity and histamine content of the fish sauce prepared with $15\%$ of table salt were $6.1\~6.2$, $14.2\~14.4\%$ and less than $10mg\%$, respectively. The fish sauce was stable during the storage of 60 days at $26\pm3^{\circ}C$ on bacterial growth and its quality was also maintained.

In other to establish the exact determination method of amino nitrogen (AN) in salt-fermented fish sauces, we determined the AN in fish sauces according to the measuring methods and also investigated the main factors influencing on determination method of AN. AN in salt-fermented anchovy sauce increased linearly as fermentation progressed, and was shown the highest amount measuring by the Formol method, followed by the trinitrobenzene sulfonic acid (TNBS) method and the Copper-salt method. AN concentration in anchovy sauces fermented for 12 months was $88.2\%$ and $77.6\%$ for the TNBS method and the Copper-salt method, respectively, on the basis of Formol method. The ratio of AN/total nitrogen (TN) in anchovy sauce fermented for 12 months was higher than that in commercial anchovy sauces. The determination of AN in anchovy sauce by the TNBS method was not affected by salt concentration, and slightly affected by heating. The effect of MSG on AN contents by Copper-salt method was shown higher than those by the Formol method and the TNBS method. The TNBS method was adaptable to measure the content of AN in fish sauce by this study.

We developed a seasoning sauce using hot water extracts from anchovy Engraulis japonica fish sauce processing by-products. A temperature of 121℃ was maintained for 120 min and the resulting amino acid content, salinity, and pH were 183.6 mg/100 g, 6.86, and 17.4 g/100 g, respectively. Radish juice, sea tangle Saccharina japonica extract, and mushroom Lentinula edodes were added to improve the flavor. The glutamic acid content of the extract mixed with 10% sea tangle extract was 88.87 mg/100 g and the 5'-GMP (guanine 5'-monophosphate) content of the extract mixed with 10% mushroom extract was 9.67 mg/ g. This study was conducted to determine optimal processing conditions for seasoned products using response surface methodology (RSM). The optimal conditions for X₁ (sea tangle extract concentration) and X₂ (mushroom extract concentration) were 15.0% and 5.0%, respectively, and the predicted values of the multiple response optimal conditions were Y₁ (5'-GMP: 17.36 mg/100 g) and Y₂ (glutamic acid: 157.35 mg/100 g). Under the optimal conditions, the experimental values of Y₁ and Y₂ were 17.32 mg/g and 155.36 mg/100 g, respectively, which are similar to the predicted values. We confirmed the feasibility of developing a seasoning sauce using hot water extract from anchovy fish sauce processing by-products and additives.

The purpose of this study was to analyze factors affecting acceptance of four kinds of dak-jjim samples in third year school-aged children (n=100). Soy sauce, red pepper paste, Vietnam fish sauce, and star anise were applied to samples for their familiar and exotic characteristics. Significant differences among samples were observed in odor, taste, and acceptance (p<0.001). Soy (Soy sauce sample), RPPaste (Red pepper paste sample), and Soy_FishS (Soy sauce and Vietnam fish sauce sample) samples scored higher than Soy_StarA (Soy sauce and star anise sample) sample. On the other hand, there were no significant differences in intensities of saltiness, sweetness, and hot spicy flavor (p>0.05). Liked attributes in samples were saltiness, sweetness, chicken flavor, potato flavor, moistness of chicken, hot spicy flavor, and color. Disliked attributes in samples were hot spicy flavor, saltiness, and ginger flavor. Significant differences among samples were observed in familiar intensity and willing to try again (p<0.001). Soy, RPPaste, and Soy_FishS samples scored higher than Soy_StarA sample. Panels considered taste (46%) and nutrition (45%). Higher familiar intensity of sample was associated with higher acceptance in samples. In other words, familiarity of food affects acceptance of food. Therefore, familiar ingredients such as soy sauce and chicken can be used for development of Korean menu items considering taste and nutrition with enhanced Korean food acceptance in school-aged children.
