With the intensified exploration of marine resources, marine bioactive peptides have become one of the research focuses in biomedicine, food science, and materials science because of their structural diversity, unique biological activities, and broad application potential. At present, the extraction of marine peptides has expanded beyond conventional chemical extraction and enzymatic hydrolysis, with microbial fermentation and gastrointestinal simulation technologies further broadening peptide diversity. In addition, the integration of multiple chromatographic techniques with advanced detectors has significantly improved the efficiency of marine peptide identification. Owing to their diverse biological activities, including immunoregulatory, antioxidant, antibacterial, antitumor, hypotensive, and hypoglycemic effects, marine peptides not only enrich the pool of candidates for marine drug development but also provide new perspectives for addressing numerous health challenges. Importantly, substantial progress has been made in the screening, identification, and mechanistic elucidation of marine bioactive peptides, driven by advances in high-throughput technologies and the bioinformatics. However, marine peptide research still faces several challenges, including complex sourcing, difficulties in large-scale acquisition, and insufficient exploration of biological activities. Therefore, this article concisely reviews recent progress in the extraction, purification, and identification of marine bioactive peptides, summarizes current research on their biological activities, and highlights the application of bioinformatics in marine peptide studies.

What’s new? Extraction and identification techniques are leveling up fast. The old chemical extraction and enzymatic hydrolysis methods aren’t going away, but now scientists are leveraging microbial fermentation and even gastrointestinal simulation. The result: a much broader range of marine peptides to work with, and more complex structures to analyze. On the detection side, researchers are pairing multi-step chromatography with high-end detectors, speeding up identification and screening.
Here’s why marine peptides matter for research:
Wide range of documented activities—antioxidant, immunoregulatory, antibacterial, antitumor, hypotensive, and hypoglycemic, just to name a few.
Real potential for new marine-derived research compounds in pharma and nutrition.
Ongoing advances in high-throughput tech and bioinformatics are making it easier to screen, map, and understand these peptides’ mechanisms.
Challenges? Sure, sourcing is still complex and scaling up production isn’t trivial. But the field is moving. Each new method—whether it’s microbial fermentation or smarter chromatography—makes these peptides more accessible for research.
Key takeaway: Marine peptide research is pushing into new territory, both in extraction tech and in the range of bioactivities being discovered.
