| Abstract: | A method of microwave digestion-kjecdahc for the determination of protein content in soybean was introduced,and microwave digestion conditions were optimized.The RSD of the method was 1.75%,the recovery was 99.2%～102.2%.There were no significant differences between determination results by this method and those by the nation standard method of China.This method could operate easily,extract quickly and be less environmental pollution.So it would provide reference for quickly determine the protein content in soybean and improve the work environment. |
