(FR) MODIFICATION DE L'HUILE
Abstract
(EN)
A pseudo-steady state fractionation of a polymorphic fat, resulting in a product which is in a kinetically stable crystal form is performed in a way that a $g(s)-value is maintained below 0.5, formula (I) wherein Sc being: the percentage solids in crystalliser at crystallisation temperature, SE being: the percentage solids after stabilisation for 48 hrs at exit temperature of crytalliser.
(FR)
Un fractionnement à l'étape pseudostable d'une graisse polymorphe, donnant un produit se présentant sous forme cristalline cinétiquement stable, est effectué de telle manière qu'une valeur $g(s) est maintenue au-dessous de 0,5 selon la formule (I) dans laquelle Sc est le pourcentage de solides dans le cristallisoir à la température de cristallisation, et SE est le pourcentage de solides après stabilisation pendant 48 heures à la température de sortie du cristallisoir.
