全自动定氮仪测定鲜牛奶氮含量条件的响应面优化
Optimization of the condition of the nitrogen content in fresh milk with response surface method by FOSS-2300 automatic Azotometer
摘要
Abstract
To determine the optimum conditions of the nitrogen content in fresh milk with the method of Plackett Burman,Steepest ascent design and response surface and optimized the optimal conditions by the experiment of stability and recovery rate,then compared with the national standard.The results showed that the optimal conditions were as followed:catalyst 8.3 g,digestion temperature 399 ℃,digestion time 230 mins.The method of determination after optimized is of better stability and recovery rate compared with the national standard method and could be practically used.关键词
