Abstract
Enzyme-Ultrasonic combined method is researched to extract sodium alginate, and the parameters are optimized as following: enzyme (cellulose and protease add content) 8%(w/v), pH 4, temperature 50°C, ultrasonic power 160 W, enzyme solution time 3.5 h. The FTIR spectrum shows the extraction material is sodium alginate. By the optimum parameters, the extraction rate is 23.1%, which is 27% higher than the traditional methods. Therefore, the extraction of sodium alginate can be increased observably by enzyme-ultrasonic combined method.
