Special Issue Information

Dear Colleagues,

Recently, the development and application of marine-derived functional factors have received extensive attention. Active peptides, polysaccharides, and oligosaccharides; polyunsaturated fatty acids; and saponins from sea cucumbers, seaweeds, mollusks, crustaceans, and other marine biological resources have shown good physiological functions, making important contributions to human health. Marine biological resources are considered a treasure house of functional factors for marine functional food. Their development has become one of the important ways to realize the efficient utilization of marine biological resources. Correspondingly, many scientific problems still require clarification regarding the metabolism and action mechanism of marine functional food in vivo, as well as the interaction mechanisms with intestinal microorganisms. In addition, toxins, heavy metals, pathogens, organic pollutants, and microplastics carried by marine biological resources also pose a huge potential safety risk to the development of marine functional food.

For this reason, a Special Issue of Foods is being released that is focused on developing technology, physiological function and metabolism, and safety control of marine functional food. It will add value to marine functional food’s scientific and technological progress, industrial development, and contribution to human health.

In recent years, cardiovascular and cerebrovascular diseases have been the focus of several studies. In this study, oyster protein hydrolysate was produced via enzyme hydrolysis and used as a fermentation substrate to ferment recombinant strain PSP2 to produce nattokinase. Using the synergism strategy, fermentation products with fibrinolytic and angiotensin I-converting enzyme (ACE) inhibitory activities were obtained and evaluated. The fermentation medium contained 1.0% trypsin, 1.0% oyster protein hydrolysate, 2.0% maltose, and 0.5% sodium chloride, with an initial pH of 7.0. The maximum nattokinase activity was 390.23 ± 10.24 FU/mL after 72 h of fermentation. The flavor of the product was improved, and heavy metals and volatile salt nitrogen were partially removed via fermentation. The ACE inhibitory activity (IC50) of the fermentation products was 1.433 mg/mL. This study provides a novel approach for the development of marine functional foods with hypotensive and antithrombotic properties. Full article

Diabetes mellitus (DM) has become the world’s third major disease after tumors and cardiovascular disease. With the exploitation of marine biological resources, the efficacy of using polysaccharides isolated from marine organisms in blood glucose regulation has received widespread attention. Some marine polysaccharides can reduce blood glucose by inhibiting digestive enzyme activity, eliminating insulin resistance, and regulating gut microbiota. These polysaccharides are mainly fucose-containing sulphated polysaccharides from algae and sea cucumbers. It follows that the hypoglycemic activity of marine fucosyl-polysaccharides is closely related to their structure, such as their sulfate group, monosaccharide composition, molecular weight and glycosidic bond type. However, the structure of marine fucosyl-polysaccharides and the mechanism of their hypoglycemic activity are not yet clear. Therefore, this review comprehensively covers the effects of marine fucosyl-polysaccharides sources, mechanisms and the structure–activity relationship on hypoglycemic activity. Moreover, the potential regulatory effects of fucosyl-polysaccharides on vascular complications caused by hyperglycemia are also summarized in this review. This review provides rationales for the activity study of marine fucosyl-polysaccharides and new insights into the high-value utilization of marine biological resources. Full article
