The Influence of Milk Standardization on Chemical Composition, Fat and Protein Recovery, Yield and Sensory Properties of Croatian PGI Lički Škripavac Cheese

The aim of this work was to evaluate the influence of cheese milk standardization on chemical composition, fat and protein recovery, yield and sensory properties of Croatian soft Protected Geographical Indication (PGI) Liˇcki škripavac cheese. Standardization of milk to the casein/fat ratio of 0.7 was carried out by adding skimmed milk powder (SMP) to cheese milk and by skimming part of the milk fat. Results showed that losses of fat by whey were significantly (p < 0.05) lower after Liˇcki škripavac cheese produced from standardized milk by skimming part of the milk fat. Standardization of cheese milk by addition of SMP caused higher losses of protein (p < 0.05) and total solids (p < 0.0001) by whey. Both methods of cheese milk standardization caused a significant (p < 0.01) decrease in milk fat and fat in dry matter content in cheese. In contrast, standardization of cheese milk caused a significant (p < 0.01) increase in protein content in cheese milk. Moisture in non-fat substance (MNFS) significantly (p < 0.05) decreased. Optimization of the casein/fat ratio did not cause a significant increase in fat recovery, but protein recovery significantly increased (p < 0.01). Addition of SMP to cheese milk significantly (p < 0.01) increased actual and adjusted cheese yield. The addition of SMP led to a noticeably higher (p = 0.10) sensory score of Liˇcki škripavac cheese.
