Table 2. The binding constant (Ka) values for the fractions (S40 and S45) extracted with supercritical CO2 fluid extraction with isolated whey protein and casein matrices without (C0) and with (T0) transglutaminase-mediated crosslinking.

Results are presented as mean value±standard deviation. Different lower case letters in a column denote significant differences between the Ka of the same sample for different fatty acids; different upper case letters in a row denote significant differences for the same Ka and fatty acid within different samples using Tukey’s test (p<0.05). The extract used for quenching experiments was a mixture of fractions m(S40):m(S45)=1:1 obtained from the extraction at 60 °C and 300 MPa
