Title (EN) POLYOL POLYESTER SYNTHESIS
(FR) SYNTHESE DE POLYESTERS DE POLYOL
Abstract:
(EN) Polyol polyesters useful as nondigestible fat substitutes are prepared by improved heterogeneous interesterification processes between fatty acid esters of easily removable alcohol and polyol characterized by having one or more improvements such as using low levels of soap emulsifying agent, catalyst, and/or excess fatty acid ester; reducing the size of the polyol by mechanical means; removing extraneous particulate material during the reaction; using low temperature and/or high pressure and compensating by increasing the mass transfer area; and/or using backmixing in the initial stage(s) and plug-flow conditions in the final stage(s).
(FR) Polyesters de polyol utiles en tant que succédanés gras non digestibles préparés par des procédés améliorés d'interestérification hétérogène entre des esters d'acides gras d'alcool et de polyol facilement séparables, caractérisés par le fait qu'ils ont été l'objet d'une ou plusieurs améliorations telles que l'utilisation de faibles quantités d'agent émulsifiant savonneux, de catalyseur et/ou d'ester d'acides gras excédentaire, la réduction de la taille du polyol par des moyens mécaniques, l'évacuation des matières particulaires étrangères pendant la réaction, l'utilisation de températures basses et/ou de hautes pressions et la compensation par augmentation de la zone de transfert de matière, et/ou l'utilisation du mélange à contre-courant dans le(s) stade(s) initial(aux et des conditions d'écoulement idéal dans le(s) stade(s) final(aux).
