A flowable nondigestible oil composition having a Consistency in a temperature range of 20 ~C to 40 ~C of less than about 600 P.sec(n-1), preferably less than about 400 P.sec(n-1). The flowable nondigestible oil contains a liquid polyol polyester having a complete melt point less than 37 ~C, and a solid polyol polyester having a complete melt point of at least about 37 ~C. The solid polyol polyester can be a solid saturated polyol polyester, a solid diversely esterified polyol polyester, a polyol polyester polymer, or a combination thereof, which are crystallized, or co-crystallized, into unaggregated crystal particles of typically less than 10 microns in maximum dimension. The flowable nondigestible oil is made by a process which includes the steps of melting completely the nondigestible oil, crystallizing the solid polyol polyester while applying shear to avoid formation of clusters of crystallized aggregates which can prevent the composition from being flowable. A preferred equipment for crystallizing the solid polyol polyester to form the flowable composition is a scraped wall heat exchanger. |
