Abstract:

To optimize the ultrasonic-assisted extraction of phytic acid from peanut meal, response surface method (RSM) was used to investigate the interactive effects of length of ultrasonic treatment, ultrasonic powder, temperature, material/liquid ratio and concentration of hydrochloric acid on phytic acid yield. The optimum conditions for the ultrasonic-assisted extraction of phytic acid were determined as follows: using 11-fold volume (mL/g) of 0.01mol/L hydrochloric acid to extract the material with the assistance of the ultrasonic treatment for 24 min at 72 W. Under such conditions, the observed value of phytic acid yield was 1.48%, in basic agreement with the predicted value, 1.44%.

Key words: peanut residue, phytic acid, ultrasonic-assisted extraction, response surface methodology
