  • In this paper, the effect of Ever-Fresh, a kind of preservatives for fish and shellfish, on fish and shrimp during ice storage were investigated. The results are as follows: 1. K value representing the ratio of optical densities of inosine and hypoxanthine fraction and total nucleotide fraction at 250nm could be useful as an index to measure the freshness of fish and shrimp during ice storage. 2. Volatile basic nitrogen could be also useful as an index to measure the freshness of shrimp during ice storage. 3. Ever-Fresh treatment of conger eel, half-beak, and shrimp appeared effective on keeping freshness during the early stage of ice storage. 4. Ever-Fresh treated shrimp showed lower thiobarbituric acid value as compared with the control during the early stage of ice storage.

  • This study was conducted to know the genetic diversity and population structure of Japanese halfbeak (Hyporhamphus sajori) in the Northeast Asia, using mitochondrial DNA control region. In the present study, a total of 70 individuals were collected from three locations of China (Liaoning), Korea (Tongyeong) and Japan (Wakasa Bay), and 47 individuals sequences from three locations of Japan (Wakasa Bay, Toyama Bay and Mikawa Bay) were downloaded from genbank. A total of 7 haplotypes were identified with 7 polymorphic sites from 358 bp length sequences. Haplotype and nucleotide diversity were very low and ranged from 0 to 0.295±0.156 and 0 to 0.0009±0.0011, respectively. Ancestral haplotype was shared by 94% individuals. An extremely low haplotype and nucleotide diversity, and starlike minimum spanning tree indicated that the species have undergone a recent population expansion after bottleneck. Pairwise FST values were low and there was no significant differences among populations suggesting a gene flow among the populations. Dispersal of the eggs with the aid of drifting seaweed and currents might be the major responsible factor for the genetic homogeneity.

  • 포항지역 주민 500명을 대상으로 꽁치과메기의 기호도 조사를 한 결과를 요약하면 다음과 같다.과메게 용어 인지 여부에 대해서는 대부분 응답자가 알고 있었으며, 과메게 시식 여부는 92.5%가 먹어 보았으며, 먹어보 지 못한 7.5%에 대해 그 이유를 알아본 결과 먹고 싶지 않았다가 61.3%를 차지하였다. 연령별 시식 여부 차이 분석에서 나이가 많을수록 대부분 과메게를 먹어본 것으로 나타났다.(P<0.05). 과메기를 먹는때는 술안주로가 80.9%로 가장 많았다. 남(86.5%), 여(56.8%)모두 술안주로 먹는 경우가 가장 많았다. 간식으로 먹는 경우도 남자(6.6%)보다 여자(16.3%)가 많게 나타났다(P<0.05). 또한 연령이 많을수록 간식으로 먹는 경우가 많았다.이러한 결과를 놓고 볼때 사철과메기의 개발 또는 포항 꽁치과메기가 향통식품으로 자리잡기 위해서는 술안주로서의 과메기가 아니라 조리방법이나 스낵 등의 가공방법 개발 등을 통하여 반찬이나 간식으로 먹을 수 있어야 진정한 먹거리로서 자리잡을 수 있을 것이다. 과메기를 처음 먹은 꼐기는 주위의 권유로 먹은 경우가 57.9%로 가장 많았다. 연령별로 살펴보면 젊을수록 과메기를 주위의 권유로 먹은 경우가 많으며, 나이가 많을수록 먹음직스러워서 과메기를 처음 먹은 계기가 된것으로 나타났다.(P<0.05). 과메기 선호도는 92.5%가 과메기에 대해 호의적인 응답을 하였다. 남자가 여자보다 과메기를 더 선화하는것으로 나타났다.(P<0.05) 연령별로는 31~40세 연령층이 과메게를 가장 선호하는 계층으로 나타났다. 과메게를 먹을때 곁들여 먹는 것으로 과메기, 생미역,초고추장으로 먹는 경우가 가장 많았다. 포항 지역 주민들은 과메기를 먹을때 대부분 생미역과 곁들여 먹지만 초고추장 없이 먹는 경우도 적지 않았다. 대부분 3~10마리 정도 1회 먹는것으로 나타났으며, 20마리 이상 많이 먹는 주민도 남녀 거의 유사하게 나타났다. 따라서 여성층의 과메기 애호가도 많다는 것(5.6%)을 알 수 있다.(P<0.05)

  • We made a survey of the pattern of dietary life, the taste and the intake-frequency for Kwamaegi in Kyungbuk province. And the results were summarized as follows : 1. Flavor(65.2%), nutritive value(14.6%), cleanliness(14.3%), price(4.3%) and calorie(0.7%) were considered to select food in that order. 2. The younger, the more they preferred foreign food to Korean food and the older, the more they preferred Korea food to foreign food. 3. Most of people(91.4%) answered positively to Kwamaegi and had a high preference of Kwamaegi. On most occasions, they were inclined to eat Kwamaegi as the side-dish(71.1%) served with drink. 4. Most of men(61.1%) have eaten 3∼10 Kwamaegis at a table, but most of women(53.7%) have eaten 1∼2 Kwamaegis at a table.

  • New drying method was tested for the Quality control for Kwamegl, dry Pacific saucy(Cololahis saira) In east coast area of Kyungbuk province, Korea. Cholesterol content of raw fish was 56% on dry basis, and decreased to 50.82 mg% rapidly the first 3 day and then, it was almost unchanged. However, the cholesterol content decreased slowly to 52.3 mg% during 15 days in new artificial drying.

  • To examine the quality changes of three typical fishes under usual storage conditions during marketing, we determined the total bacterial counts and pH values during storage of mackerel, croaker, and saury. Mackerels were stored at 0$^{\circ}C$ and on ice at 19$^{\circ}C$, which is the usual storage condition in a local market and croakers and saury were stored at 0$^{\circ}C$ and 4$^{\circ}C$. Total bacterial counts of mackerel, croaker, and saury were 3,2${\times}$10$^3$, 2.9${\times}$10$^3$, and 2.8 x 10$^4$CFU/g at the time of storage respectively. Total bacterial counts of mackerel stored on ice at 19$^{\circ}C$ increased during storage and reached to 8.4 x 10$\^$6/ CFU/g at day 6, while those stored at 0$^{\circ}C$ decreased up to 2 days of storage and increased to 5.6 ${\times}$ 10$^4$CFU/g. For croaker and saury, total bacterial counts at 0$^{\circ}C$ were 2.5 ${\times}$ 10$\^$5/ and 2.1 x 10$\^$5/ CFU/g at day 6, respectively, while those stored at 4$^{\circ}C$ had 3.6 x 10$\^$6/ and 2.6 ${\times}$ 10$\^$5/ CFU/g. the pH value or mackerel was 5.56 at the time or storage, yet it increased to 6.04. The pH changes of croaker and saury had a similar pattern with that of mackerel, which increased with time of storage. These results suggest that storage of fishes at 0$^{\circ}C$ should be better than those at 4$^{\circ}C$ or on ice at 19$^{\circ}C$ in terms of microbial safety as well as quality and shelf-life of fishes.

  • This study was designed to develop dish recipes using Heatsun sprouts to improve the sprouts' utilization and consumption. We created four kinds of dishes with Heatsun sprouts, including Acanthopanacis cortex, Kalopanax pictus, Aralia elata, and Cedrela sinensis, and analyzed their sensory properties and nutrients. In the sensory evaluation, the overall preference for all the dishes was scored higher than 3.0, Unnaumsun-dakgoginaengchae had the highest score (4.48) among the dishes. Unnamusun-dakgoginaengchae contained higher values of protein; vitamin A, E, and B6; and folic acid than the recommended dietary allowances (RDAs). The recipe for Dureupgokgammuchim was created to reduce the bitterness and the astringent taste of Aralia elata, and it was rich in vitamin C, E, and B6, as well as in folic acid and iron. Ogapisunkkonchijolim was cooked to reduce the fishy smell of a saury with the addition of Acanthopanacis cortex. It contained 1.5 times the protein RDAs, and high levels of antioxidant vitamins, including vitamin A, C, and E. Chamjugmandu was made by the mixing tofu and various vegetables without adding meat. It had the highest calorie count among the dishes, and its vitamin A, C, and E contents were higher than the corresponding RDAs.

  • In order to promote the consumption of small red muscle fish, such as saury, sardine, herring, etc., a new conditioning technique to soften backbone and small bones was investigated by using kimchi seasoning ingredients and organic acids. In the conditioning process, various chemical changes were examined during 60 days at 15 days intervals, The decrease of moisture content and the increase of salt concentration in seasoned fish meat were good correlated respectively. In the dry salt conditioning, the moisture content was more rapidly decreased than wet salt conditioning. The pH of fish meat during conditioning were more slowly decreased in dry salting than in wet salting. The VBN contents were suppressed under 30 mg/100 g in dry salt conditioning during 60 days at $5^{\circ}C$. The addition of rice bran in dry salting was effective on retarding lipid oxidation because the TBA value was most effectively retarded.

  • 소형 적색육어들은 칼슘, 필수아미노산 및 n-3계 고도불포화지방산 (DHA, EPA 등) 등이 풍부하고 각종 유용 비타민 및 정미성분 등을 함유하여 영양학적으로 우수하고 그 가공처리방법에 따라서 기호성을 부여해 줄 수 있는 잠재능을 보유하고 있다. 그 중 대표적인 것이 반건품, 염건품 및 염장품이다. 반건품은 건제품보다 수분함량이 많아 조직이 유연하고 독특한 texture를 겸비하고 있지만, 건제품에 비해 저장수명이 짧으며, 염건품은 식염첨가 후 건조를 통해 반검품의 단점인 저장성을 향상시켰으나, 원료의 독특한 풍미와 가공식품 자체의 천연적인 맛을 소비자에게 충족시키기에는 부족하다.
