The aim of this study was to evaluate the effect of β-cyclodextrin ( β-CD) on trans C18:1 fatty acid isomers, conjugated linoleic acid (CLA), polyunsaturated fatty acids (PUFA) and phospholipids in pasteurized milk. The individual trans C18:1 isomers were not significantly affected by the β-CD. trans-11 C18:1 (vaccenic acid) was found to be the major isomer (1.31 ± 0.12%) followed by trans-15 C18:1 (0.35 ± 0.06%). Individual trans linoleic acids did not show differences from the effect of β-CD, representing the high amount of the isomer trans-11 cis-15 C18:2 (0.433 ± 0.087%). The main CLA isomer cis-9 trans-11 C18:2 (rumenic acid) did not show differences between the control milk (0.672 ± 0.080%) and β-CD milk (0.663 ± 0.074%). PUFA and omega-3 and -6 fatty acids were not also significant by the effect of β-CD. Total phospholipids were not significantly affected by effect of the β-CD (0.023 ± 0.001% vs. 0.022 ± 0.001%). β-CD is a effective oligosaccharide for cholesterol removal from pasteurized milk and does not significantly affect the lipid components of the milk fat.
