摘要
针对凯氏定氮法无法快速、直接测量牛乳蛋白含量的问题,通过理论和实验数据分析,建立了利用消光法快速测量酪蛋白模拟液浓度的理论模型.利用Matlab拟合得到了消光度和酪蛋白含量的关系曲线.经研究表明,关系模型的建立使得酪蛋白含量能够被快速检测出来,证明该方法具有快速检测酪蛋白含量的可行性,这就为快速检测蛋白质含量仪器的研制和在线检测提供了理论依据.
Aiming at the problem of Kjeldahl determination cant be fastly and directly measured the protein con- tent of milk. Through analysing the theoretical and experimental data, simulation model measured the concentration of the fluid casein by using rapid extinction method was established. Using MATLAB fitting got the curve of the extinc- tion and casein content. The test results show that the establishment of the relational model makes the casein content can be quickly detected. The method has been proved that it can rapidly detect the casein content＇s feasibility, and provides a theoretical basis for the rapid detection of protein content and on-line testing equipment research.
