摘要:

用响应面法研究超声波辅助提取花生粕中植酸的最佳工艺,考察超声温度、超声时间、超声功率、液料比和盐酸浓度5 个因素对植酸提取率的影响。经响应面优化的超声波辅助提取植酸的优化工艺条件:超声温度40℃、超声时间24min、超声功率72W、液料比11:1(mL/g)、盐酸浓度0.01mol/L,此时提取率为1.48%,与模型预测值1.44% 相差不到3%。实验结果说明超声波方法可较好地应用于花生粕中植酸的提取,同时得到一个能较好预测实验结果的提取模型方程。

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
