Abstract

The aim of this study was to analyze the protein fractions of ricotta available on the Polish market. The experimental material comprised fresh (unripened) ricotta supplied by six manufacturers, purchased in retail in the city of Olsztyn. Ricotta samples were assayed for the content of water and total protein. The proteins contained in the analyzed products were separated, and the percentages of the identified protein fractions were determined. The water content of ricotta ranged from 70.76 to 80.77%, and total protein content ranged from 7.78 to 9.12%. Caseins and whey proteins, including α-lactalbumin, β-lactoglobulin, immuno­globulins, serum albumin and lactoferrin, were identified in the analyzed products. Whey proteins were the predominant protein fraction in ricotta, and their total percentage share of the identified proteins ranged from 62.70 to 95.60%.
