Characterization and Bioactivities of Sequentially-Prepared Sea Cucumber Ethanolic Extracts and Protein Hydrolysates
ABSTRACT The sea cucumber ethanol extracts (SCEEs) and protein hydrolysates (SCPHs) of Holothuria atra(HA), H. leucospilota(HL), and Bohadschia marmorata (BM) were prepared sequentially using 60% ethanol and Neutrase. The SCEE of HL contained phenolic acids (4.63 ± 0.50 µg GAE/mg extract) and was the most potent radical scavenger (91.76 ± 0.76%) at 10 mg/mL; whereas its SCPH contained hydrophobic amino acids (31.25 g/100 g) and inhibited glycation by 86.16 ± 5.92% at 5 mg/mL. Furthermore, the SCEE of HA inhibited tyrosinase by 49.93 ± 0.27% at 10 mg/mL, related to sulfated saponins (121.82 ± 3.52 µg xylose/mg extract). This study reports SCEEs as antityrosinase and SCPHs as antiglycation agents for the first time.
期刊介绍:
The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The journal features articles on various aspects of basic and applied science in topics related to:
-harvesting and handling practices-
processing with traditional and new technologies-
refrigeration and freezing-
packaging and storage-
safety and traceability-
byproduct utilization-
consumer attitudes toward aquatic food.
The Journal also covers basic studies of aquatic products as related to food chemistry, microbiology, and engineering, such as all flora and fauna from aquatic environs, including seaweeds and underutilized species used directly for human consumption or alternative uses. Special features in the journal include guest editorials by specialists in their fields and book reviews covering a wide range of topics.
