kochukaru (chili powder) and various vegetables. As its main ingredient, fresh or sea-water fish is cut into several pieces and boiled with ground beef and green vegetables such as watercress as well as garland chrysanthemum. In addition, onion, radish, chilies, crown daisy, garlic and some times, pumpkin and bean curds are added to the mixture to absorb the kochujang which is the base flavor of this dish. It is then seasoned with kochukaru, garlic, soy sauce and if needed, more kochujang to suit everyone's taste buds. Restaurants that offer this dish often allow you to select your fish from a tank. Many specialty seafood restaurants have several tanks from which you may choose a fish. Popular fish for this dish may include Korean rockfish, flounder, yellow corvina, codfish, croakers, pollacks, and even fresh water fish like carp and trout. In addition, other shell fish such as crabs, clams and oysters can be also added to this soup to compliment and enhance its spicy but refreshing flavor. This soup is one of Korean's most popular dishes while drinking soju. If you order sushi or sashimi, the soup is made from the left-over parts of the fish. The objective of this study is to determine a standardized recipe of Maeun-Tang and to investigate consumption so as to increase its intake opportunities for consumers through its development. Fish species used in Maeuen-Tang's recipes were flounder, Korean rockfish and other fish. Onion, radish, chilies, crown daisy, garlic and some times, pumpkin and bean curds were added to the mixture to absorb the kochujang which is the base flavor of this dish. Most of the stock used in Maeuen-Tang's recipes is pure water, fish stock and vegetable stock, 1.0-1.5 Korean rock fishes and 0.5-1.0 flounders, with its head and bone, which were used in 3-4 portions of Maeun-Tang. Most of the seafood restaurants used seasoning which didn't age and was made by the restaurant. The cooking equipment used in the Maeuen-Tang's recipes were a cook-port and earthen bowl.

To develop a value-added product from individually quick-frozen oysters Crassostrea gigas (IQFO), we prepared a retort pouched oyster soup (RPOS) from IQFOs and characterized its processing conditions and quality metrics. We found that the most appropriate manufacturing process for the RPOS consisted of half-thawing and washing raw IQF oysters, blanching, adding them to the retort pouch along with other ingredients (base soup stock, IQF oyster extract, radish, bean sprouts, garlic, and red pepper), sealing, retort sterilization ($120^{\circ}$, F0-value 10 min.), cooling, and packaging inspection. The moisture, crude protein, pH and salinity of the RPOS were 91.0%, 2.8%, 6.20 and 0.9%, respectively. The total amino acid content of the RPOS was 2,163.8 mg/100 g, and the main amino acids were glutamic acid, aspartic acid, leucine, proline, lysine and arginine. The primary inorganic ions were Na, K, S and Zn. In taste compounds, total free amino acid content was 313.4 mg/100 g, and the main free amino acids were glutamic acid, taurine, proline, hydroxyproline, aspartic acid, glycine, alanine, valine, lysine and arginine. This RPOS has good storage stability and organoleptic qualities compared with commercial retort pouched shellfish soup, and is suitable for commercialization as a value-added instant seafood soup.

This study aims to develop mussel stock, which is the base of sauce, soup, etc., using various nourishing elements in mussels. In mussel stock with different heating times, the moisture content was significantly different according to heating times(p < 0.05). For the color value of mussel stock, L value was highest in MS1(35.48), a value in MS1(-2.39), and b value in MS5(-9.49). pH was lowest as 6.56 in MS5, and with increased heating time, pH decreased significantly (p < 0.001). With increased heating time, the sugar content was highest as $4.03^{\circ}Brix$ in MS3 and lowest as $3.37^{\circ}Brix$ in MS1. The salinity content was lowest as 0.71% in MS1, and with increased heating time, the salinity content increased significantly (p < 0.001). The test for characteristic differences of mussel stock showed that its color intensity, transparency, fish flavor, fish taste, and salty taste increased with increased heating time. Savory taste of mussel stock was highest in MS4 with 4.33% According to the results of acceptance test, taste, and overall acceptance test, MS3 showed the best results. In conclusion, mussel stock showed great preference with increased heating time, and the preference has increased when it was heated for 15 min.

The present study analyzed the sensory characteristics of fish stock, which is the base of seafood sauce, such as moisture, ash, pH, mineral, free amino acid and sensory properties according to the additions of white wine in order to improve its taste and nutrition using its effect on the minerals and free amino acid of fish bones. As white wine was added more, water and ash contained in fish bones increased and pH decreased. When 11.5% of white wine was added, minerals such as calcium, potassium and magnesium showed the highest contents; and when 7.7% of white wine was added, sodium and phosphorus showed the highest contents. The total amount of free amino acid and general acceptance were highest when 7.7% of white wine was added. The results of this study as presented above suggest that 7.7% of white wine is most appropriate in preparing fish stock.

We attempted to apply the HACCP system adopted in the food industry to a olive flounder (Paralichthys olivaceus) aquaculture farm to ensure the hygiene safety of farmed fish. In this study, HACCP system procedures, including HACCP team organization, critical point determination, establishment of standard limits etc., were established using Codex 12 procedures. To determine whether hazards were critical elements, we evaluated the likelihood and seriousness of each hazard element. The likelihood of residual medicine exceeding the acceptable limit in shipped fish products was demonstrated to be a critical hazard element. Management of the shipment stage was determined to be a critical control point (CCP). Checking the records for stock and release and maintaining a history of medicine use before shipping the fish were suggested as monitoring methods. The standards for acceptable residual medicine were set based on relevant laws and regulations, and then the limits were adapted and established for the CCP. An HACCP plan applicable to olive flounder farms was established.

This study was performed to investigate and analyze the level of recognition, preferences and quality factors of sauces. A total of 1,340 subjects, 660 males and 680 females in the Daegu and Kyeongbuk areas participated in a questionnaire for this study. The results were summarized as follows: Among the respondents, 41.1% answered that they learned about the sauces from a western style restaurant. 73.4% of the respondents suggested that the taste and the quality of sauces had an influence on their preferences of western dishes. 51.2% of the respondents recognized that sauces are mainly used when baking and broiling; it was widely known that demiglace sauce is used on steaks. The preferred colors of sauces from most popular to least popular were brown, blond, white, yellow and red. The overall favorite stock material of demiglace sauce was beef bone. Foods that were preferred to be served with sauces were found to be beef, pea seafood, fish, shellfish, poultry and cereals from most preferred to least preferred. The favorite sauces were brown stock sauce, tomato sauce, liquor sauce, and cream sauce from most preferred to least preferred. The oil and butter sauces were preferred the least. Using a scale of 1 to 5 with 5 being the highest, the respondents rated the way sauces were cooked as the most important the quality-determining factor, with a mean value of 4.31. The raw ingredient as the most important factor was rated 4.45. Among sensory factors, the respondents agreed taste was that the most important characteristic, with a mean value of 4.65. 36.0% evaluated the overall quality of sauces as good and 47.0% as ordinary when served with western dishes. 44.1% of the respondents stated that the taste is was the topmost characteristic that needed to be improved, and that flavor and color were next in order.

The purpose of this study is to identify problems and suggest improvements of estimating procedures and item of fisheries supply-demand statistics served as a basis for the fisheries supply-demand policies. Korea Rural Economic Institute(KREI) and Ministry of Oceans and Fisheries(MOF) respectively publish the fisheries supply-demand statistics. But the reliability of data is low as the statistics of these two organizations are limited and show discrepancy in the numbers. It is therefore difficult to use them as the basic data for policies. Also, an accurate data aggregation is difficult due to following problems in the items of statistics. 1) Problems in estimating route sales and non-route sales of production, 2) adequacy of fishery product yield rate compared to raw material in the fisheries import/export sector, 3) selection of target companies for understand stocks and survey scope of fish species, 4) applying'0'to non-edible product demand etc. In order to develop the fisheries industry as a future growth industry, it is necessary to establish the accurate fisheries supply-demand policy as the instability of fisheries supply and demand is increasing. To do this, statistical reliability has to be improved. The improvements proposed in this study should be implemented considering urgency. First of all, an exhaustive analysis of stock statistics and conversion rates of raw material yield in the fisheries import/export sector should be conducted. In the medium term and the long term, transferring production statistics to MOF and surveys on the use demand of non-food product and the level of reduced and discarded seafood products should be carried out in consecutive order.

A study on sliced raw fish consumption was conducted on 300 citizens of Busan (89 men and 192 women), attending high school and university, housekeepers and employees. A self-administered questionnaire was used to record the results. The results were as follows: 93 percent of the respondents appeared to like or not be reluctant to eating Maeun-Tang. Most of the panelists had eaten at a seafood restaurant. The taste of Maeun-Tang varied differently by the spicy fish soup recipe. 56 percent of the respondents appeared to want this dish to have a fiery taste. Therefore, 89 percent of the respondents appeared to desire Maun-Tang to have a standardized recipe. The qualities of four kinds of stock made of water (A recipe), anchovy added with sea tangle (B recipe), fish bone (C recipe) and vegetable (D recipe) were investigated by using sensory evaluation and instrumental analysis for amino acids and nucleotides. The C recipe score was 80.9${\pm}$15.9 and D, B recipe was $75.7{\pm}17.1$, $75.4{\pm}17.2$, respectively. The A recipe score was $61.8{\pm}22.8$. The Degree of smooth taste were D recipe >A recipe >B recipe>C recipe. The Degree of spicy taste were C recipe >B recipe >D recipe>A recipe. In sensory evaluation, the C recipe obtained the highest score for overall preference. However, no difference of extractive nitrogen content, nucleotide and amino acid contest were observed in the C recipe after cook of Maeun-Tang.
