Manufacture of fresh soft white cheese (Domiati-type) from ultrafiltered goats' milk
2002
Mehaia, Mohamed A.
Manufacturing procedures and compositional characteristics were studied for fresh soft white cheese (Domiati-type) made from goats' milk, using ultrafiltration (UF) and conventional processes. Yields, recovery of protein, fat, total solids and sensory characteristics of this type of cheese were also evaluated. The cheeses made by UF process was higher in pH, moisture content and ash, whereas protein and fat contents were lower compared to those cheeses made by the conventional process. An increase of 21% in cheese yields, 21-26% in protein recovery, 15-19% in fat recovery and 17-22% in total solids recovery was achieved by the UF process. Moreover, the UF process showed 83-85, 83.3, 75, 82.5 and 75% reduction in the total process time, salt, starter culture, rennet and calcium chloride used, respectively. The mean score for texture of cheeses made by UF was significantly higher than that of cheeses made by the traditional process. However, a difference in flavour and overall acceptability between UF cheeses and traditional process cheeses was not verified. The most acceptable cheeses were these made with yogurt or lactic ferment starter culture.
