Dietary supplementation exerts beneficial effects in reducing incidence of chronic neurodegenerative diseases. The purpose of this study was to examine protective effects of mussel (Mytilus edulis) oligopeptides supplementation on brain function in D-galactose induced aging mice. Sixty female 8-month-old mice were randomly divided into five groups: vehicle(More)
BACKGROUND Hydrolysates prepared from sea urchin (Strongylocentrotus nudus) gonad by enzymatic treatment showed strong 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity and reducing power. RESULTS Hydrolysis of S. nudus gonad by the commercial protease papain was optimised for maximum degree of hydrolysis (DH) and trichloroacetic acid-soluble(More)
The red yeast Rhodosporidium toruloides is a known lipid producer capable of accumulating large amounts of triacylglycerols and carotenoids. However, it remains challenging to study its carotenoid production profiles owing to limited biochemical information and inefficient genetic tools. Here we used an Agrobacterium tumefaciens-mediated transformation(More)
In this study, glycogen was extracted from oyster Ostrea talienwhanensis Crosse and used as a model to investigate the structure-activity correlation of polysaccharides. Purified oyster glycogen was characterized by methylation analysis, nuclear magnetic resonance (NMR) spectroscopy and infrared spectroscopy (IR). The oyster glycogen was subsequently(More)
BACKGROUND This study has elucidated moisture dynamics in the soybean peptide, Ser-His-Glu-Cys-Asn (SHECN) powder by using dynamic vapor sorption (DVS) and nuclear magnetic resonance (NMR). We also tried to investigate the effects of moisture absorption on the biological activity and chemical properties of SHECN with some effective methods such as(More)
BACKGROUND Aquatic source gelatins are gaining more attention due to the advantages in safety and religion acceptability compared with mammalian sources. For understanding the effects of extracting temperature on gelatins from chum salmon (Oncorhynchus keta) skins (GCSS), gelatins were extracted at temperatures from 40 to 90°C and the physiochemical(More)
