Special Issue Information

Dear Colleagues,

Fish and seafood are excellent sources of many bioactive molecules, providing high-quality protein rich in essential amino acids, vitamin D, selenium, and other nutrients. Seafood is also the world’s best source of omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Their consumption has been shown to positively influence health, being related to lower blood pressure, plasma triglycerides, resting heart rate, and inflammation and the improvement of myocardial filling and efficiency and vascular function, etc.

Moreover, seafood processing is increasing with the consequent increase in by-products that are considered low value and usually discarded as waste during processing. However, seafood (fish, mollusks, crustaceans, echinoderms) by-products or waste in the form of non-edible tissues like bones, skin/scales, swim bladders, fins, visceral organs and mantle, intestines, blood, roes, liver, shell, etc., are still a rich source of valuable functional compounds with diverse biological activities.

Therefore, it is fundamental to recycle these wastes into marketable products of high value, minimizing the environmental threat. The valorization of seafood by-products and waste, which can take place in different sectors, is an interdisciplinary issue and involves various research experts such as farmers, engineers, food scientists, economists, and so on.

In this Special Issue, we invite researchers to submit original research, short communications, or review articles providing the following:

  • Physicochemical characterization and nutritional evaluation of seafood to highlight their superior biological value considering their health benefits;
  • Isolation and characterization of bioactive substances of seafood by-products and waste;
  • New strategies to improve the valorization of specific bioactive compounds;
  • New findings on potential applications of bioactive compounds.

Glycosaminoglycans (GAGs) play a crucial role due to their significant biomedical functions. Chondroitin sulfate (CS) and dermatan sulfate (DS), the main representative family of GAGs, were extracted and purified from garfish (Belone belone) by-products, i.e., skin (GSB), bones (GCB), and heads (GHB), and their composition and anticoagulant activity were investigated. CS/DS were purified by ion-exchange chromatography with yields of 8.1% for heads, 3.7% for skin, and 1.4% for bones. Cellulose acetate electrophoresis was also explored for analyzing the extracted CS/DS. Interestingly, GHB, GSB, and GCB possessed sulfate contents of 21 ± 2%, 20 ± 1%, and 20 ± 1.5%, respectively. Physico-chemical analysis showed that there were no significant differences (p > 0.05) between the variances for sulfate, uronic acid, and total sugars in the GAGs extracted from the different parts of fish. Disaccharide analysis by SAX-HPLC showed that the GSB and GCB were predominately composed of ΔDi-4S [ΔUA-GalNAc 6S] (74.78% and 69.22%, respectively) and ΔDi-2,4S [ΔUA2S-GalNAc 4S] (10.92% and 6.55%, respectively). However, the GHB consisted of 25.55% ΔDi-6S [ΔUA-GalNAc 6S] and 6.28% ΔDi-2,6S [ΔUA2S-GalNAc 4S]. Moreover, classical anticoagulation tests were also used to measure their anticoagulant properties in vitro, which included the activated partial thromboplastin time, prothrombin time, and thrombin time. The CS/DS isolated from garfish by-products exhibited potent anticoagulant effects. The purified CS/DS showed exceptional anticoagulant properties according to this research and can be considered as a new agent with anticoagulant properties. Full article
