  • A total of 57 species of fish species was collected by a trawl from the eelgrass bed in Kwangyang Bay. The dominant species were Pholis nebulosa, Syngnathus schlegeli, Leiognathus nuchalis, Pseudoblennius cottoides, Sebastes inermis, Favonigobius gymnauchen, which accounted for 69.9% of the total numbers of fish collected. Fish collected in the study area were primarily small fish species or early juveniles of large fish species. Only about 10% of fishes which were collected in the eelgrass bed exceeded 15cm in standard length. Seasonal variations in both species composition and abundance were major characteristics in the study area. The peak abundance occurred in spring, while the number of species was the highest in fall. However, both the number of species and abundance of fishes showed the lowest values in winter. High species diversity indices were observed in fall. Temperature, eelgrass standing crop and abundance of food organisms influenced seasonal changes of the fish community in the study area. More abundant and more diverse fishes were collected during nighttime than daytime.

  • This article examined the different types of Jeonuhwa as recorded in 16 royal palace studies from the Joseon dynasty (1392-1909). The ingredients used in Jeonuhwa during the Joseon dynasty were categorized as follows: 16.0% for gray mullet(秀魚) and fish(生鮮), 14.2% each for liver and cow stomach, 12.3% for sea cucumber(海蔘), 4.7% each for crab(蟹), clam(生蛤), and chunyup(千葉), 3.9% each for pork meat(豬肉), octopus, 2.8% each for oyster(石花), pheasant(生雉), and chicken(鷄), 2.0% each for croaker(民魚), and brain (骨), 0.9% each for duck(鴨子), pigeon(山鳩), dobi(都飛), snapper, white fish(白魚), mussel(紅蛤), haeran(蟹卵), quail(鶉鳥), egg(鷄卵), and sesame(實荏子). This observation may be associated with commercial industrial development that prevailed during the late Joseon dynasty. Further studies will be conducted on recipes and ingredients recorded in Euigwe in order to develop a standardized recipe for Jeonuhwa.

  • The present paper was carried out to elucidate the effect of salt-treatment and the addition of some food additives on the histamine formation and histidine decarboxylase activity in mackerel muscle during storage under different conditions. The histamine formation was inhibited by salting and histamine was hardly formed regardless of the brine concentraction during storage at $5^{\circ}C$. While, during storage at $25^{\circ}C$, the inhibitory effect upon the histamine formation and histidine decarboxylase activity was in proportion to the increase of the brine concentration. The addition of accidulants such as citric acid, malic acid and succinic acid inhibited the histamine formation and histidine decarboxylase activity. Especially, the histamine contents in the muscle added $10\%$ of citric acid and malic acid was below the critical concentration of poisoning for histamine during storage at $25^{\circ}C$ for 10 days. The histamine formation and histidine decarboxylase activity were inhibited by the $10\%$ addition of D-sorbitol, while there was no significant effect in the case of $5\%$ addition. Generally, the histamine content was increased with histidine decarboxylase activity, but didn't reveal the quantitative correlation ship with the enzyme activity.

  • Two experiments were carried out to investigate the effects of level and feeding period of dietary Monascus culture on the performance and cholesterol content of serum and meat in broilers and growing ducks.0.0(C), 0.5(T1), 1.0(T2) and $1.5\%(T3)$ of iwonascus culture which contained 0.5% monacolin-k was added to commercial broiler diets, respectively, and ffd during 2~6 weeks of age in Experiment 1. In Experilnent 2, commercial broiler diet added $1.0\%$ of Monascus culture was fed during $6\~6(C),\;4\~6(T1),\;2\~6(T2)\;and\;0\~6(T3)$ weeks of age, respectively. Three replicates of 16 day-old broilers and 10 day-old growing ducks each were randomly assigned to floor pen, respectively. In Experiment 1, as the level of dietary Monascus culture increased, body weight and feed intake of broilers significantly decreased (P<0.05), whereas those of growing ducks tended to increase without significant differences among treatments. Feed/gain ratio both in broilers and growing ducks showed a trend to increase. Cholesterol contents of serum both in broilers and growing ducks significantly decreased(P<0.05), and those of breast and thigh meat tended to decrease as the level of dietary Monascus culture increased. In Experiment 2, as the feeding period of dietary Monascus culture increased, body weight gain(P<0.05) and feed intake of broilers tended to decrease whereas those of growing ducks increased without significant differences anions treatments. Feed/gain ratio also increased without significant differences. Cholesterol contents of serum both in broilers and growing ducks significantly decreased(P<0.05), and those of breast and thigh meat tended to decrease as the feeding period of dietary Monascus culture increased without significant differences.

  • To determine the proper processing and storage conditions, physico-chemical, microbial and sensory properties of venison jerky under different dry times were measured during storage at $30^{\circ}C$ for 28 days. Samples were dried for 3 hr (T1), 4 hr (T2) and 5 hr (T3) at $75^{\circ}C$ in the smoke chamber, respectively. The pH of T1 was slightly lower than those of T2 and T3 as storage time increased. As dry and storage time increased, TBARS of T2 and T3 were significantly higher (p<0.05) than that of T1. In meat color, $L^*$ values of T3 showed slightly higher than those of T1 and T2, while at values were not clearly tendency by the passage of storage time. $b^*$ values of T2 and T3 were higher than that of T1. The water activity were significantly lower (p<0.05) in ,the order of T3$log_{10}$ CFU/g until 28 days and its number were accepted by sensory evaluation. In conclusions, T2 and T3 showed slightly high overall acceptability and lipid oxidative stability compared to T1 conditions. These results indicated that longer dry time ($4{\sim}5 hr$) of venison jerky would be better characteristics as compared to shorter dry time (3 hr) with increased storage time at $30^{\circ}C$.

  • To obtain the basic data for commercial 10% salted egg yolk for mayonnaise preparation, 3 types of egg yolks [pasteurized egg yolk (Yolk A)-not salted, pasteurized before salting (Yolk B)-salted, and pasteurized after salting (Yolk C)-salted] were prepared, and the changes in quality characteristics of these egg yolks with frozen storage were tested. The results obtained were as follows; Yolk A gelatinized during frozen storage, thus could not used for mayonnaise preparation. The viscosity of the egg yolk increased $3{\sim}5$ times after salting. Viscosity of the salted egg yolk increased with frozen storage time. Viscosity of Yolk B was higher at $-20^{\circ}C$ than $-15^{\circ}C$. Viscosity of Yolk C, however, was higher at $-15^{\circ}C$ than $-20^{\circ}C$. Frozen storage of pasteurized salted egg yolk showed some effects on the emulsification capacity. The effect, however, was smaller than that of unpasteurized salted egg yolk. Microbes of salted egg yolk were decreased with frozen storage, but there was no difference between Yolk B and Yolk C. It was suggested that commercially pasteurized 10% salted egg yolk for mayonnaise preparation can be successfully stored for 12 months at the temperature of $-15{\sim}-20^{\circ}C$.

  • Fish species composition and abundance in the waters of nearby Nakdong River estuary were investigated non-continuously and seasonally by shrimp beam trawl in summer 2007, winter 2009, and from spring 2010 to autumn 2010. During the study period, total fish species were collected 92 species, 36 families in study area. Shannon index was 1.893~2.962, and evenness was 0.050~0.231. Fish species composition was shown interannually and seasonally variations in the waters of nearby Nakdong River estuary. We carryed out cluster analysis to contain the data in previous and current study. Fish species composition was divided 3 groups which were 1987~1988 and 1998, 2001~2002, and 2007~2008 and 2009~2010. Average and minimum length in this study was longer than its in previous studies, and length range in this study was wider than its in previous studies, too. Dominant fish increased individuals and weight per unit area in this study. Especially Lophius litulon, Raja kenojei, Eopsetta grigorjewi, and Zeus faber were much better than past 2002. Liparis tanakai, Repomucenus valenciennei and Leiognathus nuchalis were dominant fish in previous study, but those decreased individuals and weight per unit area in this study.

  • This study was reviewed the changes in main ingredients, seasonings and cooking methods of Tangpyeongchae in Korean cook books and literatures published from the 1700s to the 1960s. The first published books about Tangpyeongchae were in Kosasibijib and Kyongdojabji, written in 1783 and the late 1700s, respectively. Tangpyeongchae, a representative traditional Korean dish that was royal cuisine offered at ritual events in the Chosun Dynasty, was called Cheongpochae in the royal court. It was a dish made by mixing cheongpomuk (mung bean gel), meat, dropwort, mung bean sprout, egg strips and laver. This dish has been seasoned with vinegar, soy sauce, black pepper, garlic, green onion, red pepper, salt, sugar, sesame oil and sesame salt since the early 1900s. Dropwort, egg strips, laver, pine nut (powder), red pepper powder, and red pepper threads were used as garnishes. Tangpyeongchae was made by mixing cheongpomuk with other ingredients and seasonings until the late 1800s. Since the early 1900s Tangpyeongchae has been seasoned first with other ingredients and then mixed cheongpomuk.
