Review of the polymorphism of saturated even glycerides

Abstract: In order to give a unified picture of recent findings on glyceride polymorphism a review is presented which covers in some detail the saturated single fatty acid triglycerides, the mixed C16−C18 saturated triglycerides, saturated diglycerides, and saturated monoglycerides. Mention is made, merely by way of comparison, of unsaturated and saturated-unsaturated triglycerides and unsaturated diglycerides. The value of a knowledge of glyceride polymorphism in the identification of naturally occurring glycerides is indicated by a number of examples.

Fat Crystal Networks

Abstract: This paper reviews the identification of the various levels of structure present in milk fat crystal networks, and the development of analytical techniques to quantify these levels. The relationship of the various levels of structure to macroscopic physical indicators of the mechanical strength of the network is discussed. The analysis of the microstructural level of the network via fractal geometrical methods is outlined, as well as mechanical models relating the structure to mechanical properties. The effect of processing conditions on the different levels of structure and mechanical properties also discussed. Keywords: microstructure; fat crystal network; fractal dimension; polymorphism; triglyceride; processing conditions

The polymorphism of glycerides

Abstract: During the past century, numerous workers have studied the interesting problem of the “double melting” of glycerides, and whilst it has long been known that this was due to polymorphism, the exact nature of this, and the relationship between the various polymorphic forms, was little understood. Indeed, as we now know, a clear explanation was hardly possible before the advent of x-ray diffraction methods. Once, however, that this new weapon had revealed the structure and also the general habit of polymorphism of simple long chain compounds (see Vol. 1, Ch. 1), the way was open for a new attack on this long-standing problem, and from 1934 onwards there appeared a series of thermal and x-ray studies of glycerides, by Malkin and his collaborators, which developed the present views on glyceride polymorphism. More, recently, Daubert, Lutton , and other U.S. workers have joined Malkin in this field.
