✦ Synopsis

Abstract

The non‐glyceridic fraction of fats transesterified in the presence of Na‐K alloy, and the unsaponifiable fraction of these fats were studied by chromatographic methods. α‐Diketones derived from the fatty acids components have been found to be the main by‐products of the non‐glyceridic fraction, mono‐ketones being also present as minor products. These α‐dike tones are destroyed during alkaline hydrolysis and when the unsaponifiable fraction is studied, monoketones are found as the main components. On the basis of these findings a method for detecting transesterified fats in natural fats, particularly in milk fat, is proposed.
