由you於yu牛niu乳ru中zhong的de蛋dan白bai質zhi是shi含han氮dan的de有you機ji化hua合he物wu，因yin此ci其qi測ce定ding原yuan理li是shi，將jiang樣yang品pin與yu硫liu酸suan和he催cui化hua劑ji在zai分fen路lu數shu顯xian消xiao化hua爐lu中zhong一yi同tong加jia熱re消xiao化hua，使shi蛋dan白bai質zhi分fen解jie，分fen解jie的de氨an與yu硫liu酸suan結jie合he生sheng成cheng硫liu酸suan銨an，然ran後hou堿jian化hua蒸zheng餾liu使shi氨an遊you離li，用yong硼peng酸suan吸xi收shou後hou再zai用yong鹽yan酸suan標biao準zhun溶rong液ye滴di定ding
，根gen據ju酸suan的de消xiao耗hao量liang計ji算suan出chu氮dan的de含han量liang，再zai乘cheng以yi換huan算suan係xi數shu即ji得de蛋dan白bai質zhi含han量liang。
