The quantitative estimation of the protein content in milk by means of ultraviolet spectrophotometry. 5. Possibilities for simultaneous analysis of the protein and fat content in homogenized whole milk

A new method for simultaneous analysis of the protein and fat content in milk, based on the use of UV spectroscopy, is described. The milk is homogenized to produce fat globules with mean diam. of <=1 micro m, then diluted with a 0.6% solution of alkylsulphate or alkylpolykolethersulphate. The absorption difference, A205 - A233, shows the highest correlation with the protein concn., while absorbance at 295 nm has the best correlation with the fat content.
