Prediction of thermal behaviour of fats and oils: application to palm oil and derivatives
In order to resolve the difficult problem of the relationship between properties of fats and glyceride compositions, a method of predicting the DTA curves of a complex mixture of triglycerides is proposed. This method is based on the concept of crystallisation inducer triglycerides (CITG), which induce the formation of various solid phases on cooling of the melt. A binary representation is used to evaluate the melting temperature of the phases, where CITG are opposed for their alpha and beta forms, to the alpha and beta forms of a fictitious hyperethylenic entity. The predicted DTA curve is constructed by combined triangular figures simulating DTA peaks, in proportions related to their enthalpies. The method was tested on a refined palm oil and two products resulting from hydrogenation and random interesterification of this oil. Encouraging results were obtained
