  • Patent number: 6080853
    Abstract: Polyol polyesters useful as nondigestible fat substitutes are prepared by improved heterogeneous interesterification processes between fatty acid esters of easily removable alcohol and polyol wherein the particle size of the polyol is reduced to less than 100 microns, and when the degree esterification of the polyol is between about 15% and no more than 75% substantially all of the unreacted polyol is removed. In the initial or early stages of the reaction, reaction conditions are adjusted to maintain a sufficient level of lower partial fatty acids to act as an emulsifier.
