Turning waste into value: Extraction and effective valorization strategies of seafood by-products

Waste Management Bulletin, Journal Year: 2024, Volume and Issue: 2(3), P. 84 - 100

Published: July 2, 2024

Seafood by-products from various organisms like fish, shellfish, squids, and bivalves are often thrown away as waste, even though they could be utilized in creating new types of valuable foods. Up to 75% the entire organism consists industrial processing wastes, which can lead a loss profit ecological sustainability if natural resources not recycled efficiently. Various fish parts byproducts, such heads, viscera, skin, bones, scales, exoskeletons, pens, ink, clam shells, categorized waste based on their weight percentages, vary depending species taxonomy. This review paper delves into extraction valorization strategies seafood by-products, with focus transforming resources. Marine provide bioactive substances collagen, peptides, polyunsaturated fatty acids, antioxidants, chitin, catalysts for biodiesel production. highlights utilization innovative techniques microwave- ultrasound-assisted well supercritical fluid subcritical water extract compounds section also discusses optimization processes enhance efficiency yield. Furthermore, explores potential applications across industries, emphasizing sustainable resource creation high-value products applied our current circular economy.

Characterization and Structural Analyses of Enolase from Shrimp (Litopenaeus vannamei)

Journal of Agricultural and Food Chemistry, Journal Year: 2023, Volume and Issue: 71(49), P. 19783 - 19790

Published: Nov. 30, 2023

Transcriptome analysis had recognized enolase from shrimp Litopenaeus vannamei (L. vannamei), which is termed LvEnolase, as one of the allergens, but its amino acid sequence and protein structure have been lacking. In this study, natural LvEnolase was isolated L. characterized for first time. The full-length cDNA effectively cloned, encoded 434 residues. crystal successfully determined at a resolution 2.5 Å by X-ray crystallography (PDB: 8UEL). Notably, it observed that near active center, loop exists in either an open or closed state, associated with product release phase. Furthermore, enzyme activity assays were conducted to validate catalytic capabilities purified LvEnolase. These findings significantly enhance our comprehension family provide valuable support delving into functions characteristics

Quality determination of pacific white shrimp (Litopenaeus vannamei) postlarvae using salinity shock, thermal hock, and formaldehyde dipping

E3S Web of Conferences, Journal Year: 2023, Volume and Issue: 442, P. 02021 - 02021

Published: Jan. 1, 2023

The methods of determination for Pacific white shrimp (Litopenaeus vannamei) postlarvae/PL quality were not well recognized by the user or PLs producer. objectives these trials to determine correlation salinity shock, thermal and formaldehyde (37%) dipping (dose duration) survival rate/SR 10. shock was conducted at 9, 12, 15, 18 oC. Salinity with 0, 5, 10, 15 ppt. Formaldehyde accomplished 300, 600, 900, 1.200 ppm. rate (SR) tested observed every minutes 60 minutes. results showed that demonstrated 100% in all test levels but 0 ppt, which caused a decrease SR after 30 longer exposures. lowest threshold temperature stress oC 90% SR. below 600 ppm exposure durations. findings this study provide basic information farmers regarding level salinity, temperature, during aquaculture handlings.
