interesterification1941

1941 T. P. Hilditch Industr. Chem. Fats & Waxes (ed. 2) iv. ii. 305 Suggestions have..been made..with the objects either of interchanging the acyl radicals between the triglyceride molecules of the mixture of fats used, or of introducing a certain amount of butyroglycerides into the margarine fats. Brief reference may be made to these ‘interesterification’ processes.

1961 Times Rev. Industry July 8/2 Interesterification..brings about a molecular rearrangement in the fat. This manifests itself in changes both in melting characteristics and crystal type.
