Sammendrag
The effect of the composite genotypes of αS1-κ-casein (BBAA, BBBB, BCAA) on renneting properties and yield during cheese-making of a Havarti-type cheese was investigated. Milk with αS1-κ-CN BCAA showed a shorter renneting time, while milk with αS1-κ-CN BBAA obtained the highest cheese yield. 24 h after starter addition, different protein profiles were found between the cheeses with different αS1-κ-CN genotypes. After 5 months of ripening, cheese with αS1-κ-CN BBBB contained more free amino acids than αS1-κ-CN BCAA. Cheese with αS1-κ-CN BCAA expressed a higher intensity of sweetness and lower intensity of hardness than the αS1-κ-CN BBBB and BBAA cheeses. Cheeses with αS1-κ-CN BBAA had a higher intensity of sunlight flavour than cheeses with the two other αS1-κ-CN genotypes and were assessed to be less juicy than αS1-κ-CN BBBB cheeses. The composite genotypes of αS1-κ-casein affect milk coagulation, cheese yield and cheese maturation and are highly relevant for the dairy industry.
