For this purpose,317different varieties of soybean samples were prepared. Method Forty-five soybean powder samples were treated by different sieving process, the rest of 272 soybean samples were treated by modeling analysis under optimal crushed size. Results The results showed that crushing over 60 mesh sieve crushed soybean samples had the best modeling effect, coefficient of determination in internal cross-validation of protei
