Abstract [eng] A high-performance liquid chromatography method for determination of glycomacropeptide in skim milk was improved. The effects of milk proteins precipitation temperature and freezing temperature of the samples were investigated. The use of TSK gel G 2000 SWXL column, instead of two TSK 2000 SW columns in series, reduced glycomacropeptide peak eliution time in HPLC chromatogram by 7 min. No statistically significant differences were observed in the concentrations of glycomacropeptide in frozen milk samples during the preparation of which proteins were precipitated by different methods (trichloracetic acid was added to the frozen, warmed to 8 °C or 25 °C samples).
