Early observations of partitioning effects were reported in milk fat fractionation
studies . Dolby ( 1970 ) observed that flavors concentrate in lower melting ( liquid
) milk fat , while higher melting point fats had a flat flavor . These initial ...

Observations from the study support the theory that water forms transient ice - like
ordering in the presence of apolar groups . Partition coefficients of alcohols
between milk fat and water phases deviate significantly from 1 - octanol and
water .
