  • This study aims to examine factors affecting the seafood processing business of primary cooperatives. For this purpose, I divided primary cooperatives that participate to seafood processing business into three group by sales scale. And then analyzed survey results for the four items that might be affecting the seafood processing business, type of seafood processing methods, HACCP certification status, distribution channels, processing difficulties during project implementation, etc. The result offers four implications. First, It is desirable to reduce the burden of the initial investment by leveraging the consignment process at the initial entry to seafood processing business. Second, HACCP certification is essential factor in order to promote seafood processing business as a long-term economic business. Third, To the steady growth of the seafood processing business, it is important to secure fixed large customers, as well as a individual customer. Fourth, For the continued growth of the seafood processing business it should be approached differently by way of sales, when the National Federation of Fisheries Cooperatives support to primary cooperatives.

  • 2011년 3월 동일본 대지진으로 인한 후쿠시마 원전수 유출 사고는 방사능에 오염된 수산물 섭취를 통한 방사능 피폭에 대한 두려움을 높였다. 이에 따라 우리나라 정부는 후쿠시마 인근 8개 현의 농수산물 수입을 금지하였으나 일본과의 WTO 분쟁 등으로 관련 내용이 지속적으로 보도되었고 이는 수산물에 대한 소비자의 불안을 가중시킨 것으로 보인다. 본 연구는 3년간(2018년~2020년)의 수산물 일별 구매 자료를 수집하여 일본 방사능과 관련한 보도가 국내 소비자의 수산물 구매액에 미치는 영향을 다항시차분포모형을 사용하여 추정하였다. 분석 결과 방사능 관련 기사가 언론을 통해 소비자에게 노출된 후 5일째와 6일째 이틀간 통계적으로 유의하게 수산물 구매에 부정적 영향을 미친 것으로 나타났다. 관련 기사 노출 후 소비자의 인지가 수산물 구매에 반영되는 이월효과를 보여준다.

  • The microbiological and chemical identification of antibiotic residues was attempted for livestock and seafood products including pork (n=34), beef (n=34), chicken (n=32), flatfish (n=37), armorclad rockfish (n=36), and sea bream (n=27). The meat (n=100) and seafood (n=100) samples were collected from 9 markets in 5 major Korean cities. Antibiotic substances were identified from the classes of tetracyclines, macrolides, penicillins, aminoglycosides, polyethers, peptides, sulfonamides, quinolones, chlorampenicols, and novobiocins using a microbiological assay, the Charm II test and high performance liquid chromatography (HPLC) with ultra violet (UV) and fluorescence detectors. The results showed that 2 tetracyclines (oxytetracycline and tetracycline) and 3 quinolones (ciprofloxacin, norfloxacin, and enrofloxacin) were detected in 4 samples of flatfish among all 100 seafood samples tested. No antibiotic residues were detected in the 100 livestock product samples tested. The amounts (min-max, mg/kg) of the residual antibiotics were as follows; tetracycline 0.78-0.85, oxytetracycline 0.49-0.74, ciprofloxacin 0.09-0.83, norfloxacin 0.01-0.21, enrofloxacin 0.12-2.98. These data indicate that the total detection rate of antibiotics in livestock and seafood products was approximately 2%.

  • 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.

  • This study was conducted to obtain the gelatin fraction with a high anti oxidative activity from Alaska pollock surimi by-products using a two-step enzymatic hydrolysis and ultrafiltration. Among gelatin hydrolysates from refiner discharge of Alaska Pollock surimi, the highest antioxidative activity (81.5%) resulted from gelatin hydrolysate sequentially treated with Pronase E and Flavourzyme each for 2 hr. However, no difference was seen in the anti oxidative activity of the second hydrolysate (Pronase E-/Flavourzyme-treated hydrolysate) when compared to the permeate fractionated through a 10-kDa membrane. The results suggest that the Pronase E-/Flavourzyme-treated hydrolysate from refiner discharge gelatin of Alaska pollock surimi can be used as a supplementary raw material for improving health functionality.

  • Our final goal was to manufacture low-calorie healthy seafood spreads using high pressure processing. Prior to developing the spread products, we performed a nationwide survey of consumers aged in their teens and twenties (n=585). The questionnaire was designed to gain insights from consumers on spread products, including Importance-Performance Analysis (IPA), recipes, market prospects, etc. Consumers responded that 'price, calorie, fat content, sanitary, nutrition, and food additive' should be improved, in that order. They also thought that fruits and vegetables are highly acceptable in recipes of seafood spreads. In addition, consumers pointed that we should concentrate on 'taste, sanitary, flavor, nutrition, and price' to make spreads more successful. Regarding market prospects, consumers rated spreads with scores over 2.96/5.00, which means the market for seafood spreads is sufficient. The consumers' response provided guidelines for developing and manufacturing low-calorie healthy seafood spreads.

  • The study was performed to optimize the processing conditions (alkali concentration, extraction time, and temperature) for rockfish skin gelatin based on yield using response surface methodology and comparison of the physicochemical properties with those of rockfish skin gelatin pretreated and extracted under ordinary conditions (alkali treatment concentration: 1.0 M; extraction time: 2 hr; extraction temperature: $60^{\circ}C$). Predicted maximum gelatin yield of 19.1% and gelatin content of 87.8% were obtained by extraction at $106.6^{\circ}C$ for 69.0 min after pretreatment with 1.1 M calcium hydroxide. Yield of gelatin extracted under high temperature/high pressure (G-HT/HP) was 54% higher than that extracted under ordinary temperature/time (G-OT/T). However, G-HT/HP was inferior in gel strength and gelling point to (G-OT/T), but comparable in transmission. Based on the physicochemical properties, G-HT/HP was unsuitable for use in products requiring higher physical properties, but could be useful for health-functional foods.

  • 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.

  • The effects of salt solution and chlorella on the quality of canned oyster, Crassostrea gigas, were evaluated to obtain basic data regarding the processing of two canned oyster products. In canned oyster processing, the shucked oyster meat was steamed for 20 min and then drained. Then, each can (301-3) was filled with 90 g boiled oyster in 60 mL 1.5% salt solution for the control samples or 30 mL 1.5% salt solution and 30 mL chlorella culture medium for the experimental samples. All canned products were sealed using a vacuum seamer and then sterilized to Fo values of 6-12 min in a steam retort system at 118℃. The viable bacteria count, proximate composition, pH, salinity, yield, volatile basic nitrogen (VBN), amino-nitrogen, thiobarbituric acid (TBA), mineral, color value, free amino acid levels, hardness, and sensory evaluation of the two canned products were measured under various sterilization conditions. There were no significant differences in the physical or chemical factors and little difference in the overall acceptance of the control and experimental samples.

  • We compared two different processing methods for preparing high quality frozen in-shell baby clam products. In the first method, sand and mud were removed from the clams, then they were vacuum packed in polyethylene film, boiled at $97^{\circ}C$ for 6 min, and snap frozen in a cold air blast freezer (sample 1). The second processing method was similar, except the boiling process was excluded (sample 2). Both frozen products were boiled for 4 min, and then shucked and minced. Various quality metrics, such as the opening rates of shells, chemical composition, pH, volatile basic nitrogen (VBN), salinity, thiobarbituric acid (TBA), amino-N, total amino acids and free amino acids were measured, and sensory evaluation was conducted. The opening rates of shells of sample 1 and sample 2 were 98.3% and 4.67%, respectively. The proximate composition of sample 1 and sample 2 was 75.2% and 78.7% moisture, 19.7% and 16.2% crude protein, 2.45 and 2.2% crude lipid, 2.8% and 2.1% ash, and 2.1% and 1.9% salinity, respectively. The L, a, b and ${\Delta}E$ values were similar: 48.6 and 49.2, 3.9 and 3.9, 15.7 and 15.5, and 50.7 and 50.1 for sample 1 and sample 2, respectively. The sensory evaluation score of sample 1 was higher than that of sample 2. Sample 1 was deemed to be superior to sample 2; therefore, we determined that the boiling process is needed for manufacturing high-quality frozen clam products.
