摘　　要：本文在探讨豆渣膳食纤维(soybeandregsdietaryfiber,SDF)在生理条件下(37℃、pH2、pH7)对重金属离子的吸附过程上,研究了瞬时高压作用(instantaneoushighpressure,IHP)对其过程的影响。实验结果表明:瞬时高压作用增大了SDF的最大吸附量,比40MPa处理的SDF的吸附量增加了30%～33%。经过瞬时高压处理后,SDF的吸附作用效果明显增强。On the basis of the soybean dregs dietary fiber sorption with heavy metal ions under the physiological conditions, was further studied the impact of the instantaneous high pressure （IHP） on the process. It showed that the IHP enhances the optimum sorption of soybean dregs dietary fiber, which increases 30% -33% with respect to the 40MPa process; Having been treated by IHP, the sorption of soybean dregs dietary fiber becomes quite obvious.
