Aquaculture has been playing a leading role over the years to satisfy the global growing demand for seafood. Moreover, innovative techniques are necessary to increase the competitiveness, sustainability and profitability of the seafood production chain, exploiting new species from the aquaculture, such as meagre (Argyrosomus regius), to develop value-added products and diversify their production. In the present work, the effectiveness of cold smoking combined with antioxidants (SA) compared to cold smoking alone (S) on meagre fillets, the quality and shelf life were investigated. Sensory, biochemical, physical–chemical and microbiological analyses were performed on the smoked fillets during vacuum-packaged storage for 35 days at 4 ± 0.5 °C. The results showed positive effects of the SA treatment on the biochemical parameters of meagre fillets. The total volatile basic nitrogen (TVB-N) in smoked meagre fillets was significantly lower in the SA treatment at the end of storage compared to the S treatment. Moreover, SA had a positive effect on lipid peroxidation. Lower values of malondialdehyde (mg MDA/kg) were observed in the SA treatment during preservation compared to the S treatment. This work will contribute to the growth of the fish production chain, producing a value-added fish product by exploiting meagre, whose production has been increasing over decades.

Background: The fish being highly perishable food item consumed in all strata of people. The production of freshwater fish is on the rise and need to be processed in a variety of forms to make them available for people. Nowadays, numbers of value added fish products are available in the market for consumption to achieve health beneficial effect and to cope up with malnutrition. However, consumers are unaware of the quality of the products available in the market. Therefore, the present work was undertaken to evaluate the quality of fish fingers produced from tilapia and pangasius during storage at -18±2°C. Methods: The fresh tilapia and pangasius were purchased from local market to prepare fillets. The fingers were prepared from tilapia and pangasius fillets and par fried at 180°C for 30 seconds. The fried fingers were cooled at once at room temperature and stored in deep freeze at -18±2°C for shelf-life study during November 2019 to March 2021. Result: The results indicated that the fish fingers prepared from tilapia could be stored for 33 days and pangasius fingers had a shelf-life of only 27 days. All biochemical parameters viz. pH, TVB-N, PV, FFA and TBA were found increasing as the storage study progresses. The sensory score of the fish fingers produced from both the fishes were got drastically reduced at the end of deep freeze storage at -18±2°C. Overall study indicated that tilapia and pangasius fish can be successfully utilized for the preparation of various value added fish product such as fish fingers and would have sufficient shelf life at deep freeze storage at -18±2°C.

Fish is one of the food items that become famous of the capture fisheries sector such as Skipjack fish. However, fish is categorized as perishable food therefore efforts are needed to inhibit the spoilage process by preserving and processing the fish. One of traditional Japanese fish product is Katsuo-bushi or smoked fish which processed by low temperature smoking in many hours.The purpose of this study is to study the quality and shelf life of katsuo-bushi flakes (hana-katsuo) that is packed in plastic with nitrogen and without nitrogen The methods used were organoleptic test, water content and Total Place Count (TPC), and the storage period for 0 day, 7 days and 14 days. The results showed that the organoleptic test for appearance, smell and texture with an average value of 7 which complies Indonesia national standard (SNI). Based on the water content showed that hanakatsuo which packed with plastic in nitrogen and without nitrogen have increased water content at a shelf life of 0, 7 and 14 days with the highest value with a value of 13.15%, the product still complies the SNI standards. Furthermore, the results of TPC showed that hana-katsuo which is packed in plastic with nitrogen does not complies the SNI, whereas hana-katsuo which is packed in plastic without nitrogen on day 0 is too little to count while on day 7 and 14 it does not comply the SNI.Ikan adalah salah satu bahan pangan yang banyak dicari orang sehingga ikan menjadi primadona sektor Perikanan tangkap yang diantaranya adalah ikan  Cakalang. Diperlukan adanya upaya untuk menghambat proses pembusukan dengan cara pengawetan dan pengolahan. Pengasapan ikan merupakan penggabungan dari proses penggaraman,pengeringan, dan pemberian asap untuk mencegah kerusakan ikan. Tujuan penelitian iniuntuk mengetahui dan mempelajari mutu dan masa simpan ikan  kayu bubuk yang dikemas dengan nitrogen dan tanpa.nitrogen.Metode yang dilakukan untuk uji organoleptik, uji kadar air (AOAC, 2005) dan Angka Lempeng Total (ALT) dengan perlakuan penyimpanan 0 hari, 7 hari dan 14 hari. Berdasarkan hasil penelitian uji organoleptik kenampakan, baud an tekstur dengan nilai rata-rata 7 memenuhi standar SNI. Berdasarkanhasil uji kadar air ikan kayu bubuk yang dikemas plastik dengan nitrogen dan tanpa nitogen mengalami kenaikan kadar air pada masa simpan 0, 7 dan 14 hari dengan nilai tertinggi dengan nilai 13,15 %, produk masih memenuhi standar SNI.Berdasarkan hasil penelitian ALT ikan kayu bubuk yang dikemas plastik dengan nitrogen tidak memenuhi SNI, sedangkan ikan kayu bubuk yang dikemas plastik tanpa nitrogen pada hari ke 0 terlalu sedikit untuk dihitung sedangkan pada hari ke 7 dan 14 tidak memenuhi SNI.

Novel Strategy

A novel strategy for the oxidation of Mg-based intermetallic compounds using CO<sub>2</sub> as an oxidizing agent was realized via simple thermal treatment, called ‘CO2-thermic Oxidation Process (CO-OP)’. Furthermore, as a value-added application, electrochemical properties of one of the reaction products (carbon-coated macroporous silicon) was evaluated. Considering the facile tunability of the chemical/physical properties of Mg-based intermetallics, we believe that this route can provide a simple and versatile platform for functional energy materials synthesis as well as CO<sub>2</sub> chemical utilization in an environment-friendly and sustainable way.

Depuration Process

Microbiological contamination of bivalve molluscs is one of the major concerns inherent to food safety, thus depuration is frequently needed to assure food safety levels associated with their consumption. Salinity plays an important role in the metabolic activity of bivalves and as such can influence their depuration capacity. This study aimed to evaluate the effect of salinity (25, 30, 35 and 40) on the efficiency of the depuration process, along with the quality and shelf-life of Crassostrea gigas. For this, a 24-h depuration was carried out, followed by a storage period at 5 ± 1 °C for six days. Microbiological analyses and biochemical parameters related to oxidative stress response were analysed. Escherichia coli load was reduced in only 24 h, disregarding the salinity of the system. After the shelf-life period, the activity of the antioxidant defences at salinities 35 and 40 is higher but is still not sufficient to avoid lipid peroxidation. Over time, there is a decrease in oyster metabolism probably due to being chilled and to the action of exposure to air. In sum, this study suggests salinities between 25 and 30 as preferential for the depuration process of C. gigas and subsequent quality during shelf-life.
