Determination of whey proteins in different types of milk

Popis výsledku v původním jazyce

Protein analysis is very important both in terms of milk protein allergy, and of milk and dairy product adulteration (beta-lactoglobulin may be an important marker in the detection of milk adulteration). The aim of this study was to detect major whey proteins alfa-lactalbumin and beta-lactoglobulin and their genetic variants by reversed-phase high-performance liquid chromatography. Milk samples from cows (n = 40), goats (n = 40) and sheep (n = 40) were collected at two farms and milk bars in the Czech Republic from April to June 2010. The concentration of alfa-lactalbumin was higher in goat's milk (1.27 +- 0.05 g?l-1, P { 0.001) and cow's milk (1.16 +- 0.02 g?l-1, P = 0.0037) compared to sheep's milk (0.95 +- 0.06 g?l-1); however, concentration of alfa-lactalbumin in goat's milk and cow's milk did not differ significantly (P { 0.05). Goat's milk contained less beta-lactoglobulin (3.07 +- 0.08 g?l-1) compared to cow's milk (4.10 +- 0.04 g?l-1, P { 0.001) or sheep's milk (5.97 +- 0.24 g?
