  • To develop an effective use for poor-quality individually quick-frozen (IQF) oysters Crassostrea gigas stored for a long period, the extract conditions, quality characteristics, and optimum reaction flavoring (RF) conditions of a complex extract from these IQF oysters were investigated. The moisture, pH, and volatile basic nitrogen contents of IQF oysters stored for 18 months (18M-IQFO) were 77.9%, 6.32, and 17.9 mg/100 g, respectively. Three different kinds of extract were prepared from 18M-IQFO: a hot-water extract (HE), scrap enzymatic hydrolysate (EH), and complex extract (CE). The respective extracts contained 5.5, 8.6, and 6.6% crude protein and 281.7, 366.0, and 343.0 mg/100 g amino nitrogen, and had 811, 359, and 1,170 mL/kg extraction yields. The CE was superior to the traditional HE in terms of the extraction yield, amino-nitrogen content, and organoleptic qualities, except for the odor. To improve flavor via the Maillard reaction, the reaction system used to produce a desirable flavor comprised CE (Brix $30^{\circ}$), 0.4 M glucose, 0.4 M glycine, and 0.4 M cysteine solution (4:2:1:1, v/v). The reaction time and pH were the independent variables, and the sensory scores for baked potato odor, masking shellfish odor, and boiled meat odor were the dependent variables. The surface response methodology (RSM) analysis of the multiple responses optimization gave a reaction time of 120.6 minutes and pH 7.33 at $120^{\circ}C$. The reaction improved the flavor of CE considerably, as compared to that of the unreacted extract.

  • This study presents a comparative analysis on mackerel distribution process and price formation process, and investigation of price and margin between traditional markets and Large-scale discount store distribution channel. Through this, the study investigated distribution efficiency of each channel, and examined whether a difference of distribution efficiency leads to a difference of performance through the investigation of a difference of function and role between members of a wholesale market and vendor of Large scale discount store. The following are the results of this study. As a consequence of investigating supply and sum by distribution channel of mackerel, it appeared that mackerels shipped from port market are distributed into 9 consumption sites(Wholesale market, Large scale discount store, Institutional Food Service, etc.). In the comparison of distribution efficiency between traditional retail store and Large scale discount store 52.0% margin is formed in traditional retail store distribution channel and 43.1% margin is formed in Large scale discount store, and a distribution cost rate consists of 19.4% cost in a traditional retail store for fishery products and 18.1% cost in a Large-scale discount store. To analyze a difference of performance, the study examine a difference of role and function between vendor and Wholesale market company, wholesaler and middleman. Wholesale market company and middleman of wholesale market for consumer have slightly high or similar score in collection function, sorting function, evaluation function and financial function which are traditional and original. However, it was confirmed that vendor has a better score in other functions, that is, newly-demanded functions(ex : market frontier function, product development function, Integral Distribution Function, etc.).

  • It can be said that the fishery industry in ancient China did not originally occupy a very special economic area even when it was started. At that time, the fishery industry was only treated as a means for the livelihood of ordinary people. Over time, the value and economic benefit of aquatic products began to be valued. Its origin can be said to have originated from Yugong(禹貢), which was established by King Yu. These records made it clear that the ancient kings placed great importance on the economic value of seafood and the importance of the fishery industry in the government. Thus, the fishery industry was established as a part of the socio-economic system. In ancient China, the fishery industry was one of the industrial systems that supported traditional Chinese society along with agriculture. It will be possible to analyze the way of thinking of modern Chinese people on the fishery industry through the study of the fishery industry in the traditional era of China. And based on this analysis, I think that it will be able to contribute to a certain extent in establishing a theoretical foundation for countermeasures against the reckless overfishing of fishery resources by Chinese fishermen in the West Sea, which is currently a problem.

  • The purpose of this study was to apply the activity-based costing (ABC) model to restaurant menu costing. The overhead cast of six entr${\acute{e}}$es in XYZ restaurant was calculated for all levels of activity. When comparing activity-based costing with traditional costing applied to BBQ pork rib and an assorted seafood platter, the total difference of costs between two items was 2,191 won in activity-based costing and 600 won in traditional costing. The average food cast percentage of the six entr${\acute{e}}$es was 27% using traditional costing, while the average activity-based cost percentage was 40%. Therefore, there was a 13% difference between the actual margin volume and the expected margin volume. The application of activity-based costing to the restaurant industry would be a milestone from a cost point of view as well as from a process point of view. In particular, the limitation that traditional costing only accounts for food costs could be overcome b considering the overhead cost as an important part of the cast structure. Furthermore, activity-based costing would not only help to reduce the costs associated with the process of analyzing the activities but it would also provide more accurate cost information for menu pricing.

  • Jeotgal fermentation is dependent upon a diverse microbial community, although a detailed understanding of its microbial composition is limited to a relatively small number of jeotgal. Pyrosequencing-based bacterial community analysis was performed in fermented squid, ojingeo jeotgal. Leuconostoc was identified as the predominant bacterial genus, with Bacillus and Staphylococcus also accounting for a large proportion of the bacterial community. Phylogenetic analysis with 16S rRNA genes of Leuconostoc type species indicated that L. citreum- and L. holzapfelii-like strains could be the major Leuconostoc strains in jeotgal. High concentrations of NaCl were thought to be an important factor determining the makeup of the bacterial community in the fermented squid; however, a genomic survey with osmotic stress-related genes suggests the existence of more complex factors selecting the dominant bacterial species in fermented squid.

  • N-Nitrosodimethylamine(NDMA)은 dimethylamine(DMA)과 아질산염이 반응하여 생성되고 김치의 재료 중 하나인 젓갈은 다량의 DMA를 함유하고 있다. 본 연구에서는 김치저장 중 NDMA와 그 전구물질 함량 변화에 젓갈의 종류와 양의 영향력에 대해 알아보았다. 젓갈 시료 23건 모두에서 NDMA가 검출되었고 새우젓 9건의 DMA 함량 범위는 16.5~58.9 mg/kg이고, 평균은 30.9 mg/kg이었다. 7건의 멸치액젓에 함유된 DMA 범위는 21.7~44.4 mg/kg이고, 평균은 34.5 mg/kg이었다. 김치는 5그룹으로 나누었다. 즉 멸치액젓과 새우젓을 넣지 않은 김치(대조군), 적은 양의 멸치액젓을 넣은 김치(AK1), 많은 양의 멸치액젓을 넣은 김치(AK2), 적은 양의 새우젓을 넣은 김치(SK1), 그리고 많은 양의 새우젓을 넣은 김치(SK2)로 나누었다. 김치 저장기간 동안 SK2가 SK1보다 DMA 함량이 높았고, 김치 저장 10일 후 AK2가 AK1보다 DMA 함량이 높았다. AK1과 SK1에 함유한 아질산염 함량은 김치 저장 20일에 AK2와 SK2에 함유된 아질산염 함량보다 높았다. 김치 저장 0과 10일에 NDMA 함량이 SK2 내에서 SK1 내의 그것보다 현저하게 높았고, 저장 0일에 AK2 내 NDMA 함량이 AK1 내 그것보다 현저하게 높았다. DMA와 NDMA에 대한 젓갈의 양과 종류에 대한 영향은 저장 초기에는 뚜렷하였으나 20일 동안 저장한 김치에서는 감소하였다. 이들 결과는 젓갈의 함량과 종류가 김치 내 NDMA 형성에 영향을 미친다는 것을 제안하였다.

  • 본 연구는 전통적인 발효식품인 식해에 대하여 염농도에 따른 발효기간별 품질특성, 발효 최적조건 및 유통기한 설정, 발효 최적조건에서의 생리활성을 측정하여 우리 전통식품인 식해를 저염화하고 생산 보급함과 동시에 이에 대한 과학적 자료를 제공하는 것을 목표로 하였으며 그 결과를 요약하면 다음과 같다. 본 연구에서 제조한 오징어 식해는 발효기간에 경과함에 따라 염농도가 낮고 온도가 높을수록 pH는 급격하게 감소하였으며, 아미노질소 및 휘발성 염기질소의 함량은 급격하게 증가하였다. 발효최적조건은 5% 염농도의 식해를 $-1^{\circ}C$에서 53일간 발효한 것이었고 유통기한은 염농도 5%의 식해를 $-1^{\circ}C$에서 142일간 저장한 것이었다. 식해는 DPPH 저해활성이 확인되어 항산화 효과가 있으나, hydrolxyl 및 hydrogen peroxide radical 소거능, 항당뇨, 항대장암 및 주름제거 활성은 낮아 기능성 소재로의 활용은 보충연구가 필요하다고 판단된다. 유리아미노산의 조성은 정미 아미노산이 고미 아미노산보다 많아 맛에서 우수하였으며, 시판중인 다른 수산발효식품과 관능적으로 큰 차이가 없었다. 이상의 결과를 고려할 때 $-1^{\circ}C$의 저온에서 식염 5%로 식해를 저염화 시킨다면 현대인의 식기호에 적합한 식품으로 영양학적 측면이나 시장성 측면에서 큰 효과를 낼 수 있을 것이라 판단된다.

  • In this study, we investigated e kinds and names of side dishes along with their recipes and ingredients occuring in Korean cookbooks published before the 17th century. The side dishes were classified 79 kinds of Guk, 23 kinds of Jjim and Seon, 15 kinds of Gui, 3 kinds of Jeon, 7 kinds of Nureumi, 3 kinds of Bokkeum, 30 kinds of Chae, 11 kinds of Hoe, 7 kinds of Jwaban, 6 kinds of Mareunchan, 12 kinds of Pyeonyuk and 5 kinds of Jeonyak, Jokpyeon and Sundae. The earliest records were found on Guk, Jjim, Jwaban, Po and Pyeonyuk Gui, Namul and Hoe were recorded after the 1500's and Nureumi, Jeon, Jeonyak, Jokpyeon and Sundae were developed relatively late in the late 17th century. As to the kinds of side dishes, Guk was the most common. Guks cooked before the 17th century used different recipes and more types of ingredients than today, including some that are not used today. For Jjim, various seasonings were added to main ingredients such as poultry, meat, seafood and vegetable. Most of the records found for Jjim used chicken as the main ingredient. Gui was recorded as Jeok or Gui and there weren't many ingredients for Gui before the 17th century. Gui was usually seasoned with salt or soy bean sauce and broiled after applying oil. Vegetables were broiled after a applying flour-based sauce. The Jeon cooked at that time was different from the one that is cooked today in that cow organs or sparrows were soaked in oily soy bean sauce before being stewed. Nureumi, which was popular in the 17th century, but rarely made today, was a recipe consisting of adding a flour or starch-based sauce to stewed or broiled main ingredients. Chae was a side dish prepared with edible plants, tree sprouts or leaves. Chaes like Donga and Doraji were colored with Mandrami or Muroo. Hoe was a boiled Hoe and served after boiling seafood. Jwaban was cooked by applying oil to and then broiling sparrows, dudeok, and mushrooms that had been seasoned and dried. For dried Chans, beef or fish was thin-sliced, seasoned and dried or sea tangle was broiled with pine nuts juice. There are some recipes from the 17th century whose names are gone or the recipes or ingredients have changed. Thus we must to try to rebuild three recipes and develop recipes using our own foods of today.
