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.

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.

This study aims to develop effective strategies for stimulating seafood consumption in the growing young children market, particularly at a time when interest in healthy eating is increasing. To achieve this, data from the 2023 survey on changes in seafood consumption behavior of 1,000 domestic consumers by the Korea Disease Control and Prevention Agency were utilized. The analysis was conducted using an ordered probit model, along with T-tests and chi-square tests to examine the determinants of seafood consumption. The results indicated that the presence of young children in a household significantly influences seafood consumption. This is largely due to the perception that seafood is beneficial for the health and safety of infants and toddlers. Households with young children prioritize food safety and convenience, showing a preference for pre-processed seafood, while households without young children tend to purchase unprocessed seafood and prepare it themselves. This study highlights the impact of having young children on seafood consumption and purchasing behavior, providing valuable insights for the development of targeted seafood marketing strategies and policies.

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.
