Ten samples of domestic lards, obtained from abdomen and back, were prepared and their Bömer number was measured. At the same time, fatty acid composition of the crystallized glyceride was measured by gas chromatography to examine the correlation, if any, between that and Bömer number. 1) Fatty acid composition of the crystallized glyceride from abdominal fat gave a mean value of 41.2% of C16 and 56.1% of C18 acids, while that of the back was 40.5% and 56.8%, respectively. Calculated from the C16 acid, amount of stearo-dipalmitin was 23.6% from the abdomen and 21.5% from the back, on an average. Amount larger than 30% was found in four samples. 2) Oleic acid content was 2.3% on the average and assuming from the oleic acid content, amount of mono-unsaturated glyceride was 7.5%. There were three samples with more than 10% of its content. 3) When the crystallized glyceride contains a large amount of stearo-dipalmitine and mono-unsaturated glycerides, Sg-Sf values become higher and causes high value Bomer number.
