Summary

The freeze concentration technology, based on the concentration of a liquid food at low temperatures, can contribute to the processing of milk, promoting the concentration of some specific components, such as casein, that has great impact in the rheological and functional properties of milk. The objective of this work was to evaluate the casein content of skimmed goat milk and the concentrated fractions obtained through the block freeze concentration. The application of this technology allowed the concentration of a skimmed goat milk with an initial casein content of 1.98 ± 0.01 g 100 g-1 up to 5.32 ± 0.22 g 100 g-1 in the third stage. However, by increasing skimmed goat milk concentrations, the process efficiency decreases, going from 84.59% in the first stage to 48.79% in the third stage. This new knowledge can be exploited by the industry to improve the quality of dairy products.
