Optimization of ultrasonic‐microwave synergistic extraction of polysaccharides from Morchella conica

Ultrasonic-microwave synergistic extraction (UMSE) was used to extract from Morchella conica polysaccharide (MCP). The effect of three independent variables (microwave power, ratio of water volume to raw material weight (W/M ratio), extraction time) on extraction yield was optimized using response surface methodology with a Box–Behnken design. The high R2 values (>.966) demonstrated the response and independent variables predicted by polynomial...
