Optimization of Ultrasonic Extraction of Sugarcane Leaf Polysaccharides via Response Surface Method
Response surface methodology was used to optimize ultrasonic-assisted polysaccharide(SLP)extraction from sugarcane leaves,under the optimal process conditions(360 W ultrasound power,60℃ultrasound temperature,60 min ultrasound time,and 40 mL/g liquid/feed ratio).The maximum yield of SLP was obtained to be 1.96%±0.12%.Compared with the traditional hot water extraction(HWE)method,the maximum yield of SLP was higher,which greatly improved the SLP yield(about 120%)and shortened the extraction time of SLP.The ultrasound-assisted extraction effectively increased the SLP yield,which provided reference value for the further development and application of sugarcane leaf polysaccharide extraction process.
