THE PHYSICAL AND RHEOLOGICAL PARAMETERS O F TRANSESTERIFICATED FATS

The model mixtures of triacylglycerols containing the various ratio of saturated and unsaturated fatty acids were prepared by noncontroling basic catalyze interesterification. According to the ratio of palmitic acid and stearic acid three types of mixtures varying in the content of trisaturated triacylglycerols: a) tripalmitylglycerol, b) monopalmi tyldistearylglycerol, c) tristearylglycerol were prepared. The physica l and rheological properties of transesterificated and nontransesterif icated mixtures (especially the melting point, the solidification poin t, the solid fat con-tent and the yield value - Haighton) were compare d. These parameters were correlated in dependence on the ratio of satu rated and unsaturated fatty acids and especially on the ratio of the c ontent of palmitic acid and stearic acid which seemed to be of a great value in intended system.
