“…Export of live SC is preferred as the price per kilo is about four times that of clusters (www.seafood.no). In addition, it is more favorable to be paid per kilo of the entire animal, rather than just the clusters, as by-products represent about 30% of the total SC weight (Beaulieu et al, 2009;Stenberg et al, 2012). As observed in RKC fisheries in Norway , that due to the higher price of live crabs, the proportion of SC exported live is expected to increase significantly if live storage methods improve.…”

“…By-products from the processing of SC and RKC amount to approximately 30% of the weight of the crab (Beaulieu et al, 2009;Stenberg et al, 2012). Due to the large quantities harvested, fisheries generate large amounts of crab by-products (Lage-Yusty et al, 2011;Stenberg et al, 2012).…”

“…Thus, utilizing these by-products can lead to added product-value and can benefit the environment. The byproducts of RKC and SC consist of everything but the legs or clusters of claws: the shell, the cephalothorax, the digestive system including the hepatopancreas, and physiological liquid (hemolymph; Beaulieu et al, 2009). Several valuable components are present in these by-products, such as marine oils, antioxidants like astaxanthin, chitin, minerals, as well as proteinaceous compounds (Shahidi and Synowiecki, 1991;Beaulieu et al, 2009;Lage-Yusty et al, 2011).…”

“…The proteinaceous hydrolysate from SC by-products has displayed a well-balanced amino acid composition (Beaulieu et al, 2009;Lage-Yusty et al, 2011). Similar results have been reported when analyzing the meal obtained from the by-products and shells of RKC (Stenberg et al, 2012).…”

Current Status of the Red King Crab (Paralithodes camtchaticus) and Snow Crab (Chionoecetes opilio) Industries in Norway

Red king crab and snow crab have both become important species for the Norwegian seafood industry. Since the first commercial harvest of red king crab in 2002 and of snow crab in 2012, the Norwegian seafood industry has developed new technology and knowledge for handling these species. This includes new fishing gear, conditions for live storage and processing, handling of byproducts, and entrance into new markets. The total Norwegian quota for red king crab increased from 220 metric tons in 2002 to 2350 metric tons in 2017, with a free-red king crab harvesting zone to the west of the quota-regulated area to prevent further expansion of the crab. At present, there is no established quota for snow crab. In 2016, a volume of about 5300 metric tons of snow crab was landed in Norway. In 2016, the export of red king crab and snow crab in Norway amounted to 529 million and 338 million Norwegian Kroner, respectively. Based on regular surveys of crab populations in the Barents Sea, it is assumed that the volumes red king crab and snow crab will remain steady and increase, respectively. Thus, these industries will continue to be important to the Norwegian seafood industry.

“…However, in this study, only about 20% of the total lipid entered into the lipid phase of centrifuged hydrolysates with 4 h of hydrolysis. There has been a lower value (13%) reported for snow crab (Beaulieu et al 2009). However, the results reported in other similar studies on fish by-products indicated that a much higher value could be achieved (Šližytė et al 2005;Kechaou et al 2009).…”

Abalone gonad, the major processing by-product, contains many useful components beneficial to health such as polysaccharides, proteins (peptides) and lipids. In the present study, the distribution of dry matter, protein, polysaccharide and lipid between the three centrifuged phases (sludge, aqueous and lipid phases) of the hydrolysates from abalone (Haliotis discus hannai Ino) gonad was investigated to reveal the possibility for the simultaneous recovery of the valuable components. Before hydrolysis, the dry matter, protein and sugar distributing in insoluble sludge phase were 82.05, 89.12 and 60.65% of their total amounts. After 4 h of hydrolysis, the corresponding values were reduced to 56.28, 55.47 and 31.64% for neutral protease-hydrolyzed abalone gonad, and were reduced to 57.60, 50.82 and 36.25% for alkaline protease-hydrolyzed abalone gonad. The results indicated that enzymatic hydrolysis caused the solubilization of proteins and polysaccharides from the substrate, and the two valuable components could be recovered from the soluble matters simultaneously.

Valorization of snow crab (Chionoecetes opilio) cooking effluents for food applications

BACKGROUND: Seafood processing generates significant amounts of solid and liquid waste in the environment. Such waste represents a potential source of high-value biomolecules for food, pharmaceutic and cosmetic applications. There are very few studies on the valorization of wastewaters compared to solid by-products. However, cooking waters are characterized by a high organic polluting load, which could contain valuable molecules such as proteins, pigments and flavor compounds. Snow crab (Chionoecetes opilio) processing is included among the most important processes in Canadian fisheries, although its cooking effluent composition is not well characterized. RESULTS:The present study concentrated and valorized the biomass in snow crab cooking wastewaters for the development of products for food applications. A membrane process was designed and optimized to concentrate the effluents. The chemical composition of the concentrates was analyzed, including characterizing the flavor profile compounds. The extracts were mainly composed of proteins (592 g kg −1 ) and minerals (386 g kg −1 ) and contained desirable flavor compounds. Their functional properties (solubility, water-holding capacity, oil-holding capacity) and antioxidant activities were also assessed, and their safety was verified. CONCLUSION: The cooking effluents generated by snow crab processing facilities, usually considered as waste, can be concentrated and turned into a natural aroma for the food industry.
