  • Fish extracts were processed at high temperature (136.7 ~14$0^{\circ}C$) for possible use as functional food ingredients. Raw fish meats and those hydrothermal extracts were compared with respect to in vitro and in vivo protein qualities. 95% of fat inraw meats was reduced in extracts but there were not remarkable changes in other macronutrients in freeze-dried extracts. Most of essential amino acids were decreased significantly but two times more proline and glycine were detected in extracts. High temperature cooking resulted 2.1 ~3.7 times of higher total free amino acid content infish extracts compared iwth raw meat, and taurine and glutamic acid were increased especially. Severe protein damages were occurred when invitro protein quality indices such as availblae lysine, hydrophilic browing, trypsin inhibitor formation and in vitro protein digestibility were measured on fish extracts. In vivo protein qualities were also strongly influenced by high temperature ; however rat-body-weight gain was nearly zero during PER assay, and rat PER or NPR of fish extracts were significantly lower (p<0.001) than those of cotnrol (ANRC casein) and original raw fish meats.

  • The proteolytic bacteria were isolated from the market foods such as ground beef, cooked shrimp meat, perch fillet, oyster meat, beef with textured vegetable protein and fish digest distributed at supermarket in Corvallis, Oregon, U.S.A. Two hundred and twenty-eight strains($30.8\%$) have proteolytic activity from 740 strains isolated from the examined samples and the strongest proteolytic strain among them was identified as a Streptococcus sp. Its maximum growth was showed at about 6 hours culture at $37^{\circ}C$ with shaking incubator in the medium added $0.15\%$ potassium phosphate monobasic and $0.4\%$ potassium phosphate dibasic, while the strongest activity of its extracellular protease was observed after 7 hours culture. The exoenzyme produced by the Streptococcus sp. was observed as a metal chelator sensitive protease, which are strongly inhibited by EDTA and o-phenanthroline but not affected by phenylmethylsulfonylfluoride and p-hydroxymercuribenzoate.

  • This study examined the changes of side dishes in "Eumsikdimibang", "Gyuhapchongseo", "Chosunmusangsinsikyorijebub" over time. As food ingredients, seaweed, red pepper, salted fish, Korean hot pepper paste have been used in "Gyuhapchongseo". The use of cattle by parts, saltwater fish, Chinese cabbage, powdered red pepper, garlic have increased in"Chosunmusangsinsikyorijebub". Cooking techniques, such as the use of wheat flour, a double boiler by the use of steam, and boiling and then roasting cuisine were mostly used in"Eumsikdimibang", but reduced in"Gyuhapchongseo". In "Gyuhapchongseo", the cooking methods are primarily aimed at a positive visual effect, and slices of dried meat seasoned with spices have increased. In"Chosunmusangsinsikyorijebub", various Tang (Guk), the taste of food changed by controlling the gravy content (Gigimi, Chigye, Chorim), meat mixing oil, vegetable and mushroom together to cook and boiling down the main food ingredients to soak the seasoning were increased. Dog-meat steamed dish using the intestine of dog in "Eumsikdimibang" was changed to small intestine of cattle steamed dish in "Gyuhapchongseo". And seasoned dog meat with choncho in "Eumsikdimibang" influenced on beef tail soup with Korean hot pepper paste in "Gyuhapchongseo", and Yookgyejang soup using Korean hot pepper paste in"Chosunmusangsinsikyorijebub". In steamed young chicken, the stuffing such as soybean paste, choncho, welsh onion, leek and flour in "Eumsikdimibang" was changed to minced beef, welsh onion, dropwort and Shiitake mushroom in"Gyuhapchongseo". The steamed young chicken in "Chosunmusangsinsikyorijebub" with stuffing was added to chicken soup using glutinous rice, and ginseng powder. Now, the chicken soup was changed to Samgyetang with glutinous rice, and ginseng. In "Chosunmusangsinsikyorijebub", various vegetable dishes were cooked with beef.

  • Western countries came to Asia aggressively in the early 1900s. Westerners who came to Korea at that time also had a various jobs with diplomats, missionaries, doctors, and so on. Korean diet was curious and shocking to foreigners in the early 1990s, so they made a record of the Korean diet. They thought Korea was peaceful, attractive and rich to eat. Koreans ate mainly rice and kimchi, a variety of grains, vegetables and bibimbap. Korea had a variety of meat and fish, seaweed, and herbs(ginseng). Foreigners said Koreans were greedy for food and ate a lot. Koreans ate basically a bowl of rice(bap), a bowl of soup(kuk), kimchi, soy sauce and other dishes. If Koreans wanted to set a table in abundance, they have meat soup(kuk) with meat and additional fish like as raw fish, dried fish, and boiled or fried fish. Korean people had a jangdokdae with Ongki(Earthen jar) where soy sauce(kanjang), soybean paste(doenjang), red pepper paste(kochujang), pickles (jang-achi) have been fermented. Foreigners felt the smell of lacquer tree and kimchi hung in the air from Korean people. While they were compared it to the smell of western rim cheese burger, they said Korea was a country with nasty smell in the feet. By the records of foreigners in the early 1900s, Korean's diets and image were appeared objectively.

  • An investigation on optimum processing conditions for meaty textured fish protein concentrate (MT-FPC) was carried out with the fish meat of filefish, Navodon modestus, and sandfish. Arctoscopus japonicus. The processing conditions were determined by the lipid content and the rehydration capacity of MT-FPC. The optimum pH and sodium chloride content of fish meat were 8.0 and 1.0%, respectively. The most effective soaking conditions were: soaking time in chilled ethanol was 15 min for both filefish and sandfish; amount of chilled ethanol, 3 volumes and 4 volumes for filefish and sandfish, respectively; temperature of chilled ethanol, $25 ^{\circ}C$ for both filefish and sandfish; soaking time in boiling ethanol, 15 and 25 min for filefish and sandfish, respectively; amount of boiling ethanol, 2 and 4 volumes for filefish and sandfish, respectively; and number of snaking in boiling ethanol, 2 and 4 times for filefish and sandfish, respectively. Yields of the product to the minced meat weight, the contents of protein and lipid in MT-FPC prepared from filefish were 13.7%, 84.5% and 0.2%, and those from sandfish were 12.5%, 84.2% and 1.1%, respectively.

  • The friend fish meat paste was prepared to enhance physiological functions by adding 0, 5, 10, 15, and 20% of king oyster mushroom (Pleurotus eryngii). The properties of fried gel were evaluated the color, quality properties and sensory characteristics. L-value was decreased, and a-value and b-value were increased by addition of king oyster mushroom. The folding test showed good level (AA). The quality properties showed that 10% addition of mushroom was the highest values in strength, hardness, gumminess and brittleness. The fish meat paste added 10% mushroom gave the highest favorite score in color, flavor, and overall acceptance. The results suggest that king oyster mushroom can be applied to fish paste for the purpose of high quality and functionality.

  • This study aimed to develop a new commercialization model for theindustrialization of head family food as a gentry families' complex food culture product. We tried to develop a head family food and propose a city sightseeing style's head family product by interviews with 'Hakindang' as the center, the head house of the Suwon Baek clan, and Injaegong group in Jeonjoo. Hakindang (in Jeonju) was confirmed as an improved model Korean-style house in the enlightenment period and the twentieth style modern head family as emerging capitalist. Hakindangsupported independence war funds in the Japanese colonial era and was widely known as gate of filial piety in Jeonju. Representative seasonal foods of Hakindang include pan-fried sweet rice cake with flower petals in the spring, hot spicy meat stew and polypus variabilis in summer, hanchae in autumn, and napa cabbage kimchi with salted flatfish seafood in the winter. When parents-in-law had a birthday, there were party noodles, sliced abalone stuffed with pine nuts, brass chafing dish, fish eggs, slices of blilde meat, and matnaji. Daily, there were mainly salted seafood, slices of raw fish, grilled short rib patties, braised fish, baked fish, syruped chestnut, grilled deodeok root, bean sprouts, radish preserved with salt, dongchimi, soy sauce-marinated horseshoe crab, butterbur, perilla seed stew, salted clams, raw bamboo shoot, agar, fried kelp, etc. The most basic virtue of the head family is filial duty, and they developed mosim dining as a representative food of Hakingdang's head family. The mosim menu is composed of 65% carbohydrates, 20% protein, and 15% fat because it is table for parents-in-law like more than 75 years old. The sensory evaluation showed a chewy texture that is easily swallowed.

  • The changes of the get forming ability of common carp (Cyprinus carpio) and conger eel (Astroconger myriaster) meat during ice and frozen storage were investigated in connection with the other quality indices, such as pH, K-value, VBN, viable cell count and sensory evaluation. The shelf-life of iced common carp and conger eel as the raw materials for fish jelly product was considered to be about 16 and 13 days, respectively. Little change in gel forming ability of two species was found during frozen storage at $-30^{\circ}C$ for 3 months. From the results obtained in the examination on the gel forming abilities of the two species stored at $-30^{\circ}C$ for 3 months were superior to those stored in ice for 3 to 4 and 4 to 6 days individually. Fish jelly from the common carp was much more elastic than that of conger eel meat. The overall qualities of two species held in frozen storage as the raw material for fish jelly product were excellent.

  • In present paper, we investigated the changes in lipid components of skipjack and Alaska pollack meat by thermal processing at high temperature. TBA values and peroxide values of both fish meats decreased markedly by heat treatment; decreasing range of TBA and peroxide values in skipjack meat was larger than those of Alaska pollack meat. Also carbonyl value of skipjack meat was decreased by thermal processing, contrary, that of Alaska pollack meat was increased. Total lipid(TL) of skipjack and Alaska pollack meat consisted of $61.9\%,\;49.6\%$ non-polar lipid(NL), $38.1\%,\;50.4\%$ polar lipid(PL), respectively. When the samples were heated at the Fo values of 5 or higher, contents of NL were increased, while that of PL were decreased. In fatty acid composition of NL and PL in both fishes, NL revealed higher contents in saturates and monoenes such as 16:0, 18:1, while PL showed higher contents in polyenes such as 20:5, 22:6; percentages of polyenes such as 22:6 especially in both fishes decreased with increasing of Fo values. The remaining ratio of PUFA(20:5+22:6/16:0) of Fo 20 samples in skipjack and Alaska pollack meat were $73\%$ and $65\%$, respectively. However, when the samples were heated at $98^{\circ}C$ for 30 minutes, no appreciable changes occured in fatty acid composition of TL, NL and PL in both fish meats examined.
