Continuous Flow Analysis Of Non-Casein Protein In Milk, Robert Steven White
Continuous Flow Analysis Of Non-Casein Protein In Milk, Robert Steven White
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Technicon AutoAnalyzer II was evaluated for automatic quantitation of non-casein protein (NCP) in milk. The Lowry method for colorimetric measurement of proteins was adapted to the automated method and found to be accurate in the determination of non-casein protein in milk. The automated Lowry method obeyed Beer's law. Casein content was calculated by difference between total protein determined by infrared milk analysis (IRMA) and non-casein protein. In the analysis of twenty-five replicate milk samples, the standard deviation was 0.32 and the coefficient of variability was 0.90. The casein content as a percentage of total protein in the milk of …
