Insoluble protein occurring in dried skim-milk during storage was determined by staining with amido black 10B, following disk electrophoresis. Increases of alpha s- and beta -caseins and a remarkable increase in relative proportion of alpha s-casein were observed, with a significant decrease in kappa -casein during storage. By carbohydrate staining with acid-Schiff technique following electrophoresis, insoluble protein was detected in 3 fractions.
