When the ultrasonic power is 80W, the polysaccharide yield reaches a relative maximum. Ultrasound power is also one of the factors affecting the polysaccharide yield. The decrease in polysaccharide yield when the ultrasonic power is 90W may be due to excessive ultrasonic shear forces and shock waves. Destruction of polysaccharide molecules has led to a reduction in polysaccharide yield [71].
