Changing concepts in fishery science increasingly are recognizing depletion of traditional stocks, utilization of alternate(non-traditional) species, demand for high quality products, and a total resource utilization approach. Innovative practices are occurring in fisheries processing wherein solid and liquid discharges are no longer treated as 'waste,' but rather as valuable feedstocks for recovery of a variety of value-added ('value enhanced') by-products. Among these are protein hydrolysates, soluble proteins and amino acids, proteolytic enzymes, flavor and flavor extracts, pigments, and biopolymers such as chitosan. Properties and applications of this deacetylated derivative of chitin are noted. Crustacean processing by-products are discussed in terms of their serving as materials for generation of natural flavors and flavor extracts, and products such as fish sauces using contemporary enzymatic techniques. Various food and feed applications of fisheries processing by-products are illustrated with increased usage seen in formulated diets for an expanding aquaculture market. Examples are given of aquaculture becoming increasingly significant in global fisheries resource projections. Critical issues in the international seafood industry Include those of seafood quality, processing quality assurance (HACCP), and recognition of the nutritional and health-related properties of fisheries products. A variety of current seafood processing research is discussed, including that of alternate fish species for surimi manufacture and formulation of value-added seafood products from crawfish and blue crab processing operations. Increasing emphasis is being placed on international aspects of global fisheries and the role of aquaculture in such considerations. Coupled with the need for the aquatic food industry to develop innovative seafood products for the 21st century is that of total resource utilization. Contemporary approaches in seafood processing recognize the need to discard the traditional concept of processing 'waste' and adapt a more realistic, and economically sound, approach of usable by-products for food and feed application. For example, in a period of declining natural fishery resources it is no longer feasible to discard fish frames following fillet removal when a significant amount of residual valuable flesh is present that can be readily recovered and properly utilized in a variety of mince-based formulated seafood products.

The purpose of this study is to analyze consumer preference for fish farm HACCP certification using conjoint analysis. This study used raw flatfish product to evaluate the fish farm HACCP. In this study, 500 consumers were surveyed using panel survey and stratified sampling. In the recognition analysis, the farm HACCP certification system was found to be highly recognized by consumers. It can be seen that the brand assets accumulated by existing food and agricultural HACCP certification were transfered to the fish farm HACCP and absorbed. Consumers perceived fish farm HACCP certification as similar one with existing food and agricultural HACCP. Conjoint analysis evaluated three levels factors. The attributes and levels evaluated were : price(25,800 won, 28,400 won, 31,000 won), certification(fish farm HACCP, seafood traceability, and non certified), and origin(domestic, JEJU, and WANDO). The important levels were in order of price(40.8%), certification(30.2%) and origin(29.0%). We found that consumers give higher utility to fish farm HACCP certification compared with non certified and seafood traceability certification. Market simulation results showed that the fish farm HACCP product has 12%p higher market share than non certified products. Seafood traceability certification showed 4.6%p higher market share than non certified products.

본 연구는 학교급식 수산물 식재료의 적절한 가격 결정을 위하여 공급업체와의 계약, 납품 현황 및 수산물 식재료의 사용 현황과 수산물 식재료 가격 인식, HACCP 적용 편익에 따른 영양(교)사의 가격 인식을 조사하였다. 대부분의 학교(96.5%)가 수산물 전문 취급업체로부터 납품받는 것으로 조사되었다. 납품 시 계약 위반을 경험한 학교가 42.1%였고, 특히 빙의로 인한 무게 감소를 이유로 반품 및 교환을 한 학교가 총 89곳(60.1%)인 것으로 나타났다. 현재 공급되는 수산물 식재료에 대한 만족도는 '제품의 가격', '제품의 품질', '원산지 진위'에 대한 항목에서 수의계약으로 납품되는 수산물이 경쟁입찰방식으로 공급되는 식재료보다 유의적으로 높아(P<0.05) 계약방법에 따른 수산물 식재료의 만족도는 차이가 있었다. 응답자들의 재계약 의도 또한 경쟁입찰로 선정된 공급업체보다 수의계약으로 선정된 공급업체에 대해 유의적으로 높게 인식하고 있는 것으로 조사되었다(P<0.001). 학교급식 수산물 식재료의 가격요소 반영 정도는 '이윤($5.96{\pm}1.15$)'과 'HACCP 지정 및 유지 비용($5.57{\pm}1.40$)' 항목이 현재 납품되는 수산물 가격에 가장 크게 반영되는 요소로 인식하고 있었다. 반면 향후 수산물 식재료 가격 산정에 가장 많이 반영되어야 한다고 응답한 요소는 'HACCP 지정 및 유지 비용($5.29{\pm}1.39$)'이고, 가장 낮게 반영되어야 한다고 인식된 요소가 '이윤($4.12{\pm}1.12$)'인 것으로 조사되었다. 또한 '가공비용'을 제외한 나머지 5개 가격요소 모두 현재 가격 반영 정도와 향후 기대 가격 반영정도 간의 유의적인 차이가 있는 것으로 조사되었다(P<0.05). HACCP 지정 수산물 식재료 구매 시 미지정 제품에 비해 얼마나 비용을 추가적으로 지불할 의사가 있는가에 대한 응답은 9.9%의 응답자를 제외한 대부분의 응답자들이 추가 지불 의사가 있는 것으로 조사되었다. 수산물은 산지에서 수확되는 생산량과 어획 시기에 따른 물량 확보의 가변성으로 시장 가격에 대한 객관성이 부족하다. 특히 학교급식에 납품되는 수산물 식재료의 가격은 재래시장이나 할인점 등에서 임의로 조사된 근거에 따라 전자입찰 예정가격이 산정되는 문제점도 있을 것으로 사료되어 수산물 식재료의 가격산정과 관련하여 구매방법 전반에 대하여 논의가 이루어져야 할 것이다. 본 연구의 결과는 수산물 식재료의 가격 산정에 대한 소비자 측면에서의 가격 인식과 수산물 식재료의 구매에 관한 정보를 제공함으로써 학교급식에서 양질의 수산물을 공급하고, 합리적인 수산물 가격 결정을 통해 수산물의 소비를 촉진하는 데 기여할 것으로 기대된다.

The surge in online seafood consumption has increased parcel delivery, leading to a need to implement effective preservation methods. As the cold chain system is not fully established in Korea, styrofoam boxes and cold packs are commonly used for low-temperature seafood distribution. The impact of cold packs on product preservation depends on the number utilized. Herein, the freshness of vacuum-packed frozen fish fillets (Paralichthys olivaceus and Scomber japonicus) stored at 25±0.5℃ for up to 84 h was measured. Chemical (pH and volatile base nitrogen), microbiological (viable cell count), and physical (odor intensity) properties were assessed using 2 or 4 cold packs in a styrofoam box. Four cold packs yielded lower values, indicating superior freshness, and extended fish freshness by approximately 12 h compared with two cold packs. Therefore, it is recommended to use a minimum of 4 cold packs (-350 g/cold pack) in a styrofoam box for distributing approximately 300 g of frozen fish fillets at room temperature during the summer, considering an average delivery period of 2 days in Korea.

This study examines a business survey on the utilization of fishery by-products with the aim to assess the feasibility of incorporating these by-products into various industries. The research involved surveying 312 biocompanies across the country and conducting an empirical analysis based on the collected data. South Korea, a leading seafood-producing country with a developed seafood processing industry, provides conditions necessary to utilize seafood by-products as raw materials for the marine bioindustry. Among the surveyed biocompanies, 38.5% expressed their intention to engage in industrial activities involving the use of fishery by-products in the future, indicating a significant level of interest within the bioindustry in utilizing marine and fishery by-products. Companies showed interest in diverse materials, such as scales, fish bones, skin, and kelp holdfast beyond those currently defined under the Fisheries By-products Recycling Promotion Act (officially unnamed, 2021). This suggests a need for improvements in the regulatory framework to accommodate these diverse biomaterials. Furthermore, we propose enhancing the efficiency of fishery by-product utilization by focusing on regional specialization in marine bioindustry. This involves utilizing existing legal framework for upcycling fishery by-products and fostering a regionally specialized marine bioindustry.

Cooking drips which were obtained as by-product after seafood processing in the food industries, still contain lots of proteins, carbohydrates, and other functional materials. This study was conducted to investigate the effect of gamma irradiation on the biological activities of seafood cooking drips. When the cooking drips of Hizikia fusiformis, Enteroctopus dofleini and Thunnus thynnus were irradiated, the antioxidant activities, whitening effect, and angiotensin I converting enzyme inhibition activity of the ethanol extract from seafood cooking drips were all increased by gamma irradiation. This was because of the increased extraction efficiency of available compounds by irradiation. These results suggested that the seafood cooking drips, wasted as by-products, can be used as functional compounds with gamma irradiation treatment.
