Optimization and characterization of polysaccharides extraction from Giant African snail (Achatina fulica) using pressurized hot water extraction (PHWE)

Achatina fulica was treated by pressurized hot water to extract bioactive polysaccharides and the extraction process was optimized with the extraction yield by response surface methodology (RSM). The optimized condition was temperature of 133.53 °C, water to solid ratio of 54.11 mL/g, and time of 14.95 min, and the yield of the polysaccharide was 42.39% ± 0.85%. The characterization of polysaccharide was comprised of preliminary, physical, and...
