Abstract: A reaction mixture for manufacturing polyol fatty acid polyesters comprises a polyol, a fatty acid lower alkyl ester, a base initiator and a phase transfer catalyst. The phase transfer catalyst can be a quaternary ammonium compound, a crown ether, a polyethylene glycol, a polyethylene glycol ether, a polyethylene glycol ester or mixtures thereof. The process of making polyol fatty acid polyesters is carried out at low temperatures and essentially in the absence of a solvent or emulsifier. The polyol fatty acid polyester product stream produced by the foregoing process and reaction mixture has a lower concentration of reaction by-products such as di-fatty ketones and beta-ketoesters and of caramelized by-product which results from the breakdown of the polyol reactant.

Abstract: Nondigestible fat compositions useful as replacements for triglyceride fats or oils in foods are disclosed. These compositions have relatively flat solid Fat Content (SFC) profile slopes between typical room temperature and body temperature. The nondigestible fat compositions comprise a liquid nondigestible oil and nondigestible solid polyol polyester particles dispersed in the oil in an amount sufficient to control passive oil loss. The solid polyol polyester particles of the composition herein comprise from about 10% to 50% polyol polyester polymer and from 50% to about 90% polyol polyester monomer. The polyol polyester material which forms these solid particles must contain a relatively high proportion of long chain saturated fatty acid ester groups. Edible fat-containing products comprising these nondigestible fats can be less waxy tasting due to the lower level of solids required for passive oil loss control.

Abstract: Solid nondigestible polyol polyesters wherein the ester groups contain (1) fatty acid radicals having at least one hydroxyl group that is esterified with another fatty acid or other organic radical, and (2) at least about 15% long chain (C.sub.20 or higher) saturated fatty acid radicals. The molar ratio of (1):(2) is from about 0.1:7.9 to about 3:5. These solid nondigestible polyol polyesters are very efficient passive oil loss control agents for liquid nondigestible oils. Edible fat-containing products including nondigestible fats containing these solid polyol polyesters can be less waxy tasting due to the lower level of solids required for passive oil loss control.

Abstract: Nondigestible fat compositions useful as a replacement for triglyceride fats or oils in foods are disclosed. These compositions have relatively flat Solid Fat Content (SFC) profile slopes between typical room and body temperatures. The nondigestible fat compositions comprise a liquid nondigestible oil and nondigestible particles of solid polyol polyester material dispersed in the oil in an amount sufficient to control passive oil loss. The ester groups of the solid polyol polyester material comprise (i) at least about 15% ester groups formed from C.sub.20 -C.sub.26 long chain saturated fatty acid radicals, and (ii) ester groups formed from fatty or other organic acid radicals which are dissimilar said long chain saturated fatty acid radicals. The molar ratio of said dissimilar acid radicals to said long chain saturated fatty acid radicals ranges from about 0.1:7.9 to about 3:5. Moreover, the dissimilar acid radicals cannot consist solely of C.sub.2 -C.sub.12 short chain saturated fatty acid radicals, C.sub.

Abstract: Polyol polyesters having reduced color content are prepared by base-catalyzed transesterification of lower (i.e., C.sub.1 -C.sub.3) alkyl fatty esters having a carbonyl content of less than about 200 ppm with polyols. The esters can be prepared by a pretreatment comprising distilling the said alkyl fatty esters (in a liquid state), preferably with a base, and discarding both the top cut in an amount that is about 5% or less and at least about 2% of the still bottoms.

Abstract: Spent copper "chromite" catalyst from the hydrogenation of carboxylic acids or esters of such acids is regenerated by vacuum treatment at high temperature to reduce the level of organic residue on the catalyst to less than about 25%, followed by oxidation.
