| Abstract: | The rapid determination method of protein content in soy protein isolate has been set up by using the KDN - 08A automatic - manual nitrogen determination apparatus that was designed based on the kjeldahl principle. There is no significant difference between the results from above method and kjeldahl, The recovery rate reached 99.53% -100.19%. So the rapid method is accurate, rapid,and simple;and can practically used for the determination of protein content in soy protein isolate. |
