Optimization of Enzyme Assisted Extraction Technology of Flavonoids from Seabuckthorn Fruit Peel Marc
Abstract:
Enzyme assisted extraction of flavonoids from seabuckthorn fruit peel marc was studied by response surface methodology(RSM), using a Box-Behnken experimental design. A mathematical polynomial model was proposed with regard to investigate the effect of cellulase dosage (x1), enzymolysis temperature (x2), and pH value (x3)to the flavonoids yields. These factors were further optimized using RSM. The optimal conditions were: cellulase enzyme dosage was at 73.3IU/g, temperatur was at 53.7°C and the pH was at 4.14. Under the optimum conditions, gave rise to the highest flavonoids yields, approaching 8.02 mg/g of flavonoids yields.
