Optimization of Ultrasonic-Assisted Extraction of Polysaccharides from Blackcurrant Using RSM

Abstract:

Ultrasonic-assisted extraction (UAE) method was applied for polysaccharides from blackcurrant and response surface methodology (RSM) was used to optimize the effects of processing parameters on polysaccharides yields. Three major independent variables such as ultrasonic power (W), extraction time (min), liquid to solid ratio (mL/g) were studied. The optimal extraction conditions of polysaccharides were determined as follows: ultrasonic power 402.2 W, extraction time 25.5 min, liquid to solid ratio 20.3:1 mL/g. Under a modified conditions (ultrasonic power 400W, extraction time 25 min, liquid to solid ratio 20:1 mL/g, the experimental yield of polysaccharides was 11.19%, which was agreed closely with the predicted value (11.24%).
