  • This study was targeted on the non-processed, semi-processed, and full-processed seafood to investigate the consumers' importance and satisfaction levels of purchase attributes for each seafood product. The present study conducted a survey on 335 randomly chosen seafood consumers. Respondents' importance-satisfaction scores of purchase attributes were measured. The results were as follows. The importance of purchase attributes was significantly higher than the satisfaction on 21 out of 23 attributes, according to the non-processed, semi-processed, and full-processed seafood(p<0.05). Consumers regarded intrinsic attributes such as 'freshness' of products as very important when purchasing non-processed seafood, and their satisfaction was also high. On the other hand, for semi-processed and full-processed seafood, external attributes such as 'date of manufacture or expiration date' were considered as more important attributes to purchase them. Consumers also perceived that full-processed seafood was less in quantity and more expensive than non-processed and semi-processed ones. In case of semi-processed seafood, the difference of importance-satisfaction score for 'taste' was large, and it was considered the taste should be improved according to consumers' taste.

  • The purpose of this study is to understand the perception of fishery products and processed food of marine products in college students through empirical analysis. 446 questionnaires were used in the analysis. As a result of the empirical analysis, the frequency of consumption of aquatic food was 2~3 times a week, the place of intake was good for taste of home and aquatic foods, respectively. Purchase motifs of processed fish products are easy, the frequency of ingestion is 3 to 4 times a week, the criteria for selection were always consumed, and the taste was considered to be high when purchased. The perception of nutrition and necessity of consumption of aquatic foods was high and radioactivity was low. 133 male students (57.8%) and 98 female students (45.4%) were aware of the aquatic traceability system. The college students generally has a high preference for the taste of marine products and high frequency of consumption, and they recognized that nutritional excellence and necessity were positive. The marketing strategy should be developed by developing proper product considering the age level and sex of consumers. The limitation is that they are college students in Busan and Gyeongsang provinces and coastal areas.

  • Values are lasting beliefs that are at the center of human behavior and not be often changed. Different values make different behaviors, and similar values form similar behaviors. Consumers' values affect not only the cognitive process but also behaviors in a powerful and comprehensive way. There have been many studies regarding prediction of consumer patterns and identification, measurement methods of values. This is because if we can accurately measure the value system, it can be used in many areas of marketing such as market segmentation, new product development, and advertisement. In case of seafood, it is also necessary to make marketing strategies by segmenting consumers based on their value systems. The objectives of this study are as follows: First, it is to find out the connection process from the properties of seafood products that consumers consider important, to the benefits, and finally to the values they pursue by applying the means-end chain theory, using the Laddering method. Second, using a two-step cluster analysis, we aim to segment seafood markets based on consumers' values and investigate characteristics of segmented markets. Based on objectives, it is expected that this study would provide informations on seafood consumers and help to establish seafood marketing strategies for producers and distributors. Analytical results of the value system using a means-end chain theory indicated that there were seven complete links, that is, ladders among fresh seafood products. In case of processed seafood products, there were total 9 complete ladders. The empirical analytical results of market segmentation according to the values showed fresh seafood products were divided into three groups. In case of processed seafood products were segmented into two groups.

  • The purpose of this study was to assess bacteriological hazards in the following 7 kinds of minimally processed shellfish products purchased from Korean seafood retail outlets: raw oysters stored with seawater in polyethylene bags, frozen oysters, raw mussels, frozen mussels, boiled mussels, raw short-necked clam, and frozen short-necked clams, obtained from Korean seafood retail outlets. The total coliform and Escherichia coli counts determined in all samples were detected below regulation limit of the Korean government guidelines (Food Code). In addition, the high-risk bacterial pathogens, Listeria monocytogenes, Salmonella spp., and E. coli O157:H7 were not detected in any samples. Low-risk pathogens such as Staphylococcus aureus and Vibrio parahaemolyticus were detected at levels above $1.0{\times}10^2$ colony forming unit (CFU)/g in some minimally processed shellfish products. Notably, S. aureus was detected in all samples. Raw oysters stored with seawater in polyethylene bags, frozen oysters, and boiled blue mussels are commonly ingested without heating, and therefore these minimally processed shellfish products pose bacteriological hazards. The detection of S. aureus in all shellfish products, an organism indicative of poor personal hygiene, which can grow and multiply during distribution, indicates the necessity of improving the food safety of minimally processed shellfish products.

  • Mackerel Scomber japonicus is an excellent source of vitamins (A, D and B12), omega-3 fatty acids, dietary protein and minerals. This study was conducted to prepare mackerel-based processed seafood products such as grilled product with super-heated (GM), tang (TM) and salad with sweet potato (SSM) using mackerel as senior-friendly seafoods and to examine their quality characteristics. The hardness of GM, TM and SSM were 240.3×1.03, 21.7×1.03 and 7.4×1.03 N/m2, respectively. The viscosity of SSM was 25,450 m·Pas. The nutritional content of mackerel-processed products was within the senior-friendly standard specifications for protein, vitamin C, vitamin B2 (riboflavin) and vitamin B3 (niacin) ing GM, protein, vitamin B3 and calcium for TM, and protein, vitamin D, vitamin B2 and vitamin B3 in SSM. All the mackerel-processed products were safe as senior-friendly seafoods, since digestibility rates were 81.5% for GM, 87.9% for TM and 93.5% for SSM. The physical, nutritional and the sanitation results indicated that senior-friendly seafoods classified of the mackerel-processed products was step 1 for GM, step 2 for TM and step 3 for SSM according to the Korean Food Code and Korean Indusrty Standards.

  • This study analyzed the determinants that affect the purchase of ready-to-cook seafood products using the "Consumer Attitude Survey on Processed Foods" from 2018 to 2021. Dietary lifestyle, food awareness and preference survey questions were categorized, and factors affecting the purchase probability of ready-to-cook seafood were identified through a binomial logit model. The main research findings are as follows. First, consumers had higher preference for quality, safety, and new taste factors than health and price factors when purchasing HMR (Home Meal Replacement). Second, through binomial logit model analysis, the probability of purchasing ready-to-cook seafood products was low in the group pursuing taste and economy. On the other hand, the purchase probability was high in the group seeking convenience. Third, the purchase probability of ready-to-cook seafood products was higher in households with two or more persons than in single-person households. These results suggest that differentiated product development and marketing strategies should be needed for each consumer groups in the seafood convenience food market.

  • By-products from fisheries produced in Korea are of the same industrial material as imported raw materials and are valuable resources for marine bioindustries. Securing raw materials for the mass production of functional materials is one of the main objectives for marine bioindustrial development. The use of fishery by-products as raw materials is anticipated to increase rapidly as the biomarket is growing into a promising industry. In this study, data were acquired from an open-source environment to perform exploratory data analysis, and various visualization methods were used to compare fishery production to the production of marine processed products in the year 2020. This study suggested that the amount of seafood processing, types of processing items, and areas where fishery processing residue is generated, should be able to secure hygienic raw material supply in large quantities. Thus far, it has been found that the Gyeonggi-do and Busan province, where HACCP-certified processing facilities are concentrated, and the local government Seafood Cluster and the Smart Aquaculture Cluster are at the forefront of stable, mass production of raw materials.

  • This study used the big data method to analyze the chronological frequency of seafood appearance and variety mentioned by the veritable records of the Joseon dynasty. The findings will be used as a basis for Joseon Period's food cultural research. The web-crawling method was used to digitally scrap from the veritable records of the Joseon dynasty of Joseon's first to the twenty-seventh king. A total of 9,536 cases indicated the appearance of seafood out of the 384,582 articles. Seafood were termed "seafood" as a collective noun 107 times (1.12%), 27 types of fish 8,372 times (87.79%), 3 types of mollusca (1.28%), 18 types of shellfish 213 times (2.23%), 6 types of crustacean 188 times (1.97%), 9 types of seaweed 534 times (5.60%). Fish appeared most frequently out of all the recorded seafood. Sea fish appeared more frequently than the freshwater fish. Kings that showed the most Strong Interest Inventory (SII) were: Sungjong from the 15thcentury, Sehjo from the 15th, Youngjo from the 18th, Sehjong from the 15th, and Jungjo from the 18th respectively. Kings of Chosen were most interested in seafood in the 15th and 18th centuries.

  • The objective of this study was to analyze bacteriological and chemical hazards in minimally processed commercial fish products, including Hwangtae (freeze-dried pollock), dried anchovy, fermented anchovy sauce, and salted and dried yellow croaker. Escherichia coli counts from all samples were below the regulation limits of the Korean Ministry of Food and Drug Safety Standards on Quality of Seafood and Seafood Products (Food Code). However, the food poisoning bacterium Staphylococcus aureus was detected at levels above $1.0{\times}10^2$ colony forming units (CFU)/g in Hwangtae, dried anchovy, and salted and dried yellow croaker, which are commonly ingested without heating and pose bacteriological hazards. The detection of S. aureus, an organism indicative of poor personal hygiene, which can be introduced by employees and multiply during distribution, indicates the necessity of improving the sanitary control of minimally processed commercial fish products. Histamine was not detected from dried anchovy or salted and dried yellow croaker, but was detected at some of the highest levels in fermented anchovy sauces. This result suggests that efforts to reduce the amount of histamine in fermented anchovy sauces are required.

  • The study aims to identify the generation and treatment of fishery by-products in Korea and suggests future directions and strategies for their eco-friendly utilization and industrialization. First, the study focuses on the identification of the generation and their treatment in Korea since merely few study were conducted and they did not provide enough information regarding the overall generation and treatment at the national level. According to the estimation, Korea generates 800 thousand to 1,200 thousand tones of fishery by-product every year. The fishery by-products generated at large seafood markets and processing facilities are used or processed as fish meal and feed, but those generated from households and small seafood restaurants are currently treated as food waste. In addition, inadequately treated fishery by-products cause various problems such as spoiling urban landscape, creating odor and incubating pest. After identifying the generation and treatment of fishery by-products, the study suggests directions for the formulation of infrastructure for transition into resource circulation society, minimization of dumped waste and their eco-friendly recycling as resources, diversification of recycled goods and development into a high-value added industry. Finally, the study suggests detailed strategies for the directions such as establishment of legal and institutional foundation, separation of fishery by-products from wastes, development of technology tailored for commercialization, introduction of pilot projects for industrialization and cultivation of social enterprises.
