A simple and rapid procedure for phytate determination in soybeans and soy products

Abstract A rapid and simple analytical procedure to determine the phytate (myo‐inositol hexaphosphate) content in soybeans and soy products is described. Minimal sample preparation and automated HPLC analysis were achieved for large numbers of samples. Determination of the phytate content in a variety of soybean samples, including animal feeds, demonstrated the simplicity, reliability, and economy of the procedure compared with other time‐consuming, complicated, and laborious methods.
