Experiments on the grading of butter by chemical analysis


, : Experiments on the grading of butter by chemical analysis. Vorratspfl. u. Lebensmittelf orsch, 2: 11/12, 672-681

The numbers of points given for flavour when butters were graded were compared with the results of various chemical tests proposed as measures of flavour. Tests included estimations of steam-volatile acids and steam-volatile esters, pH of a steam distillate, colorimetric estimation of methylnonylketone inmolten butter before and after filtration, reduction of permanganate by a distillate, and numerous other procedures.
