Effect of genetic polymorphism of milk proteins on rheology of chymosin-induced milk gels
Individual milk samples from 121 cows in mid lactation of the Swedish Red and Swedish Holstein breeds with known protein genotypes of β- and κ-casein and β-lactoglobulin were analysed. Chromatographically pure chymosin was added to skim milk and rheological properties of the gels were measured using...

description | Individual milk samples from 121 cows in mid lactation of the Swedish Red and Swedish Holstein breeds with known protein genotypes of
β- and
κ-casein and
β-lactoglobulin were analysed. Chromatographically pure chymosin was added to skim milk and rheological properties of the gels were measured using a Bohlin VOR Rheometer. Coagulation time (CT) and curd firmness after 25
min (G′
25) were registered for each sample. The B allele of
κ-casein was associated with improved coagulating properties of milk, whereas the E allele showed a negative effect on these traits. The
β-casein A
2A
2 genotype was associated with inferior milk coagulation characteristics. Total protein concentration of milk was positively associated with curd firmness, but showed no association with milk coagulation time. |
