Title: Distribution of trans-unsaturated fatty acids in milk fat
Abstract: Milk fat, before and after randomization, was separated into 8 fractions by crystallization from acetone. The trans-unsaturated fatty acid content of the milk fat was 8.6% and in the fractions ranged from 8.1 to 11.1%. The ratio of trans to total unsaturation was 0.23 in the whole fat and decreased from 0.82 in the highest melting fraction to 0.16 in the lowest melting fraction. As randomization caused only minor changes in these values it was concluded that ttrans-unsaturated fatty acids are distributed at random between glycerides. The 2-monoglycerides isolated from original and randomized milk fat and their fractions contained no measurable amounts of trans unsaturation, and it was, therefore, concluded that virtually all of the trans-unsaturated fatty acids were located in the 1 and 3 positions of the glycerides.
