Mercury is an element of special concern for human health. Measurements of total mercury levels in fish have been taken into consideration to assess risk. In this study, the Antarctic toothfish Dissostichus mawsoni was evaluated as a potential safe food source through measurement of total mercury contents. Total mercury concentrations in Antarctic toothfish ranged from $0.101{\pm}0.047mg/kg$ to $0.139{\pm}0.075mg/kg$. The total mercury concentration was significantly correlated with macroscopic values including total fish length, weight, gonadosomatic index, and maturity (P < 0.01 or 0.05). Furthermore, according to the risk assessment, the total mercury body exposure rate from Antarctic toothfish ranged from 2.125% to 2.847% of the Provisional Tolerable Weekly Intake. Therefore, the Antarctic toothfish could be used as a potential safe seafood source.

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 recent mass appearances of jellyfish in Korea have caused economic and social damage, as they plague swimmers and fishermen. However, jellyfish have high economic and nutritional value, and contain low levels of calories and hydrolysates. Thus, jellyfish are a natural, healthy food that can improve high blood pressure, bronchitis, and a multitude of other diseases. Here, we present research on the ecology, classification, bloom, damage caused, food component characterization, and tissues of jellyfish, with the aim of facilitating further study. Research on use of jellyfish as salted products, and for collagen and qniumucin would also be valuable. A jellyfish body is classified into three parts: the body, termed the umbrella; the oral arm; and the tentacle. Jellyfish are planktonic marine members of a group of invertebrate animals comprising the classes Schypozoa (phylum Cnidaria) and Cuboza. In Korea in 2012, jellyfish damage resulted in decreases of annual catch and commercial value estimated at 177 and 141 billion won, respectively. Because concentrations of heavy metals are below the safety limits for seafood, dried jellyfish appear to be safe raw materials for food. The proximate compositions of Nemopilema nomurai and Aurelia aurita were 97.1% and 96.5% moisture, 0.9% and 1.2% crude proteins, undetected and 0.1% crude lipids, and 1.7% and 1.8% ash, respectively. According to their total contents of essential, total, and non-essential amino acids, jellyfish gonads were deemed good-quality protein. Because the major functional components of jellyfish are collagen and qniumucin, jellyfish can be used salted, or these components of healthy diets can be extracted from them. For more effective use of jellyfish, unit costs should be decreased and safety guaranteed. Additionally, dehydrators attached to conveyor belts should be developed. Since jellyfish can be used throughout the year, they should be listed in the Korean Food Standards Codex as a food source.

오징어 내장유를 식용자원으로 이용하기 위한 일련의 연구로서 젤라틴, 물 및 정제 오징어 내장유로 형성된 유화물의 첨가에 의한 어육버거의 품질개선을 시도하였다. 과산화물값, 갈변도, 헌터색조, 젤리강도 및 관능검사의 결과로 미루어 보아, 고등어버거의 기능성 개선을 위한 유화물의 적절한 첨가량은 마쇄한 고등어육에 대하여 6%로 판단되었다. 채육한 고등어육에 대하여 6%에 해당하는 유화물을 첨가하여 제조한 고등어버거는 휘발성 염기질소, 총균수 및 히스타민함량이 각각 19.0 mg/100g, $6.2{\times}10^4CFU/g$ 및 50.7 mg/100g으로 그 함량이 낮아 식품위생적으로 안전하다고 판단되었다. 유화물 첨가 고등어버거의 포화산에 대한 고도불포화지방산의 비율은 1.13이었다. 색조, 젤리강도, 지방산조성 및 관능검사를 측정한 결과 유화물 첨가에 의해 고등어버거의 색조, 조직감 및 지질의 기능성을 일부 개선할 수 있었다.
