Optimization of polysaccharides extraction from Pacific oyster (Crassostrea gigas) using subcritical water: Structural characterization and biological activities

Bioactive polysaccharide was extracted from Pacific oyster Crassostrea gigas using subcritical water (SW) and the extraction process was optimize by response surface methodology (RSM). The optimum condition was found to be temperature 125.01 °C, extraction time 14.93 min, and liquid to solid ratio of 44.69:1 (ml:g). At this condition, the yield of the C. gigas polysaccharides (CGPs) was found to be 18.66%. The polysaccharide was characterized...
