Kinetic mechnisms for the extraction of active constituents from waste residue of the soybeans using extraction method

The kinetic mechanism of the soybean isoflavones extraction process was researched by organic solvent extraction. The kinetic of solvent extraction process agreed with the first-order rate equation. The experiments for extracting soybean isoflavones from the waste residue of the soybeans were studied under different conditions to evaluate the kinetic equation based on Fick's first law of diffusion. Experimental data could match the kinetic equation. It gives a valuable theory basis for the comprehensive utilization and extraction of active constituents from the waste residue of the soybeans.
