This study focuses on a recent WTO SPS dispute related to Korea Import Bans and Testing and Certification Requirements for Radionuclides (DS495) in order to learn from the case and take proactive measures to prevent potential import restrictions by Japan on Korean seafood. Korean-Radionuclides (Japan) emphasizes the importance of sufficient scientific evidence, especially scientific information from relevant international organizations, in an effort to take preventive measures towards Japan's restrictions on Korean seafood imports. Japan claims that a novel parasite, Kudoa septempuctata, in Korean flatfish causes food poisoning. As food poisoning is a serious concern, there is a low possibility that Japan's enhanced monitoring measures would be more trade restrictive than required as prescribed in Article 5.6 of the WTO SPS Agreement. In addition, Korea is the biggest exporter of olive flounder to Japan. Hence, the possibility that similar conditions could be established is low in relation to non-discriminatory principles under the WTO SPS Agreement. Accordingly, we should collect relevant scientific evidence, improve domestic sanitary management of fishery products, and seek export diversification so that we prepare for potential import restrictions by Japan and minimize implications.

A traditional Korean seafood (fermented anchovy) is made from the muscle and viscera of anchovies Engraulis japonica. This study was undertaken to investigate the effect of retorting condition on the quality of canned, salt-fermented anchovy fillet using red pepper paste with vinegar. Salt-fermented anchovy fillets were prepared by fermenting anchovies with salt (15%) at $5^{\circ}C$ for 15 days, and then cold air drying the fillets for 1 hour. Each batch of dried fermented anchovy fillets (60 g) was filled with 35 g of mixed red pepper paste with vinegar (red pepper paste 64%, vinegar 2%, starch syrup 13%, sugar 14%, coke 6%, soju 0.4%, crushed garlic 0.3%, ginger 0.3%), placed in a can (RR-90), seamed using a vacuum seamer, and sterilized for either Fo 9 or 11 min in a steam system retort at $121^{\circ}C$. After sterilization, we measured the pH, total volatile basic nitrogen (TVB-N), amino-N, color value (L, a, b), texture profile, thiobarbituric acid (TBA) value, sensory evaluation, and viable bacterial count of the canned fillets. We did not detect viable bacterial counts in cans subjected to either sterilization treatment, and there was no difference in physicochemical and sensory quality between the two. In fact, most sensory evaluators reported difficulty distinguishing the products. Thus, our results show that sterilization for Fo 9 min is preferable to that for Fo 11 min in the preparation of canned salt-fermented anchovy fillet using red pepper paste with vinegar.

This study was investigated for the purpose of obtaining basic data for application to the canning process of salt-fermented anchovy Engraulis japonica fillet using tomato paste. The salt fermented anchovy fillet was prepared by fermenting anchovy fillet with salt 15% at $5^{\circ}C$ for 15 days and then cold air drying the salt-fermented anchovy fillet for 1 h at $16{\pm}1^{\circ}C$. The dried salt-fermented anchovy fillet 85 g was filled with 60 g of tomato paste sauce (tomato paste 42%, gum guar 1.0%, salt 2.0%, starch syrup 2.0%, cooking wine 1%, water 52%) and seamed by vacuum seamer in 301-3 can, then sterilized at Fo 9 and 11 min in a steam system retort at $121^{\circ}C$, respectively. The factors such as chemical composition, pH, total volatile basic nitrogen (TVB-N), amino-N, color value (L, a, b), texture profile, thiobarbituric acid (TBA) value, sensory evaluation and viable bacterial count of the canned salt-fermented anchovy fillet were measured. Texture value of the product sterilized at Fo 11 min was higher than at Fo 9 min condition. In both sterilized cans, the viable bacterial counts were not detected. There was no remarkable difference in physicochemical between sterilization conditions. As a result of sensory evaluation, most sensory evaluation inspector judged that it was difficult to distinguish the sensory difference of both products sterilized at Fo 9 min and at 11 min. The results showed that sterilization of Fo 9 min was more desirable than that of Fo 11 min to prepare canned salt-fermented anchovy fillet using tomato paste sauce, because this condition is more economical.

This study was performed to obtain basic data regarding the development of fish steak products using olive flounder and pork leg. Olive flounder and pork leg were ground separately in a chopper. The methods used for processing were as follows. Chopped olive flounder (100 g) and other ingredients (bread crumbs, 13 g; onion, 12 g; garlic, 4 g; egg wash, 18 g; salt, 0.05 g; pepper, 0.05 g) were mixed in a chopper. The mixture was molded into a steak shape ($12{\times}7cm$) and roasted in an oven at $180^{\circ}C$ for 12 min (OF). FP consisting of a mixture of olive flounder (70 g) and pork leg meat (30 g) and OP consisting of pork leg meat alone (100 g) were processed according to the same procedure as described for OF. Various factors (viable bacterial count, chemical composition, pH, salinity, hardness value, color value, total amino acid content, free amino acid content, fatty acid composition, mineral content) were measured, and sensory evaluation was conducted. Based on the results of the sensory evaluation and hardness value, OP was deemed to be the most desirable, followed in order by FP and OF. There was a slight but significant difference between OP and FP.

This study investigated the sensory characteristics (texture, odor, taste and color) of jerky produced from ground sea rainbow trout (SRT) Oncorhynchus mykiss frame muscle (FM). The hardness of the ground SRT-FM jerky was 453.9±91.0 g/cm², which was lower than that of commercial animal jerky (893.5±404.6 g/cm²) and commercial fish jerky (1,394.4±363.5 g/cm²). The difference in the hardness values of the ground SRT-FM jerky and commercial animal jerky was not significant. The volatile basic nitrogen content of the ground SRT-FM jerky was 48.3±1.6 mg/100 g, which was higher than that of commercial fish jerky (21.6±6.2 mg/100 g) and commercial animal jerky (18.2±6.3 mg/100 g). However, the fish odor of the ground SRT-FM jerky was masked by the presence of various additives. The hydrophilic and lipophilic browning indices of the ground SRT-FM jerky were higher than those of the commercial jerky. The total taste value of the ground SRT-FM jerky was 169.0, and the major amino acids were glutamic acid and aspartic acid. These results suggest that ground SRT-FM jerky would be acceptable to consumers.

This study was conducted to compare the sensory and enzymatic properties of Israeli carp Cyprinus carpio muscle (ICM) according to size [normal large (NLF) and small fish (NSF)], part [ventral (VM) and dorsal muscles (DM)], and commercial value [NLF, recessive (RF), or deformed fish (DF)]. There was not difference in salty of all samples. The sourness was stronger in NLF and DM than in NSF, RF, and DF, and VM, respectively. The umami of ICM showed no size-associated differences; however, those of DM, and DF and RF, were superior to those of the VM and NLF, respectively. The sweetness was also stronger in NLF than in NSF and RF, and in DM than VM. The sweetness of DF didn't differ compared to those of NLF and RF. The intensity of fish odor was weaker in NSF or DF than that in NLF, and was higher in DM than in VM. The color of ICM was bright in NSF and DF compared to NLF. Enzyme activity was very low in the muscles and high in viscera. Therefore, ICM could be used as a material for seafood products, regardless of size, part, and commercial value; however, the issue of lipid oxidation must be considered.

Boil-dried concentrates (BDC) and steam-dried concentrates (SDC) were prepared from highly nutritious olive flounder Paralichthys olivaceus roes (OFR) as seafood processing by-products and their nutritional characteristics were investigated. Although SDS-PAGE profiles of the BDC and SDC proteins were similar to each other, it was observed that three of the five OFR protein bands in the 50-100 kDa range had disappeared. We also detected significant differences in the Hunter's color of the two concentrates in terms of color difference (𝚫E) and whiteness. The recovery amounts of BDC and SDC prepared from 100 g of OFR were 18.6 and 21.4 g, respectively, with respective protein contents of 67.7% and 68.9%. The main amino acids of OFR and concentrate proteins were valine, leucine, lysine, arginine, aspartic acid, glutamic acid and alanine, whereas major minerals were sulfur, potassium, sodium and phosphorus, the amounts of which in concentrates had been significantly reduced. We established that by sterilizing, inactivating endogenous enzymes, and inhibiting microbial growth, the cook-dried process contributes to enhancing the concentration and storage stability of nutrients by reducing water activity, volume, and weight. Accordingly, we suggest that concentrates (BDC and SDC) prepared from OFR have considerable potential as nutritionally fortified materials.

This study was conducted to prepare canned salmon frame and to characterize its food components. In the preparation of high-quality canned foods, the boiling water generated in the pre-heating process should be removed, and then the pre-treated canned salmon frame should be sterilized for an $F_0$ value of 12 min. The proximate composition of the canned salmon frame prepared under optimal conditions (CSFP) was 58.4% moisture, 15.7% protein, 21.4% lipid, and 3.5% ash. Based on the results of volatile basic nitrogen and microbiological tests, the CSFP was acceptable. The sensory score for the color of CSFP was 4.1 points, which was higher than that of commercial canned salmon frame (CCSF). However, there were no significant differences in the sensory scores for flavor and taste between CSFP and CCSF. The total amino acid content of CSFP was 14.58 g/100 g, which was 4.9% lower than that of CCSF. The major amino acids in CSFP were aspartic acid (11.0%), glutamic acid (14.8%), and lysine (10.6%), which accounted for 36.4% of the total amino acid content. The CSFP was high in calcium and phosphorus, while it was low in magnesium and zinc. The major fatty acids in CSFP were 16:0 (15.2%), 18:1n-9 (17.0%), 18:2n-6 (16.7%), 20:5n-3 (9.3%), and 22:6n-3 (8.8%). Based on the results, CSFP is a high-quality canned food in terms of hygiene and nutrition.
