The heat-treatment of cheese milk, or whey, to denature the whey proteins has long been the most applied means of recovering these proteins, either directly in the cheese curd, or as added to the cheese milk prior to renneting. In heat-treated milk, the interaction of the denatured whey proteins with the casein micelles, however, limits the primary phase of the enzymatic reaction, and prevents ...

The cheese industry faces many challenges to optimize cheese yield and quality. A very precise standardization of the cheese milk is needed, which is achieved by a fine control of the process and milk composition. Thorough analysis of protein composition is important to determine the amount of protein that will be retained in the curd or lost in the whey. The fluorescence-based Amaltheys analyz...

Milk samples with low (<500,000/ml), medium (500,000-1,000,000/ml) and high (1,000,000-2,000,000/ml) Somatic Cell Counts (SCC) were obtained from a flock of 120 Sarda breed ewes. Milk was analysed for chemical composition and rheological properties (Formagraph), and used for a laboratory scale cheesemaking. The milk of the three groups showed differences (P<0.01) in pH, lactose, whey protein an...

Cheese is the most complex of the dairy products, involving chemical, biochemical and microbiological processes. The steps in all cheesemaking include milk acidification, milk coagulation, whey removal, packaging and storage. Most cheesemaking also includes heating the cheese curd and salting the curd. Even slight changes in these processes can lead to significant differences in the final chees...

Milk protein is often standardised prior to cheese-making using low concentration factor ultrafiltration retentate (LCUFR) but the effect of LCUFR addition on the microstructure of full fat gel, curd and Cheddar cheese is not known. In this work, Cheddar cheeses were made from cheese-milk with or without LCUFR addition using a protein concentration of 3.7%-5.8% w/w. The fat lost to sweet whey w...
