  • Nondigestible fat compositions containing diversely esterified polyol polyester for passive oil loss control
    Patent number: 5480667
    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.

  • Nondigestible fat compositions containing cocrystallized blend of polyol polyester hardstock and crystal modifier as a passive oil loss control agent
    Patent number: 5451416
    Abstract: Nondigestible fat compositions having relatively flat Solid Fat Content (SFC) profile slopes between typical room and body temperatures are disclosed. These nondigestible fat comprise a liquid nondigestible oil and relatively small nondigestible particles dispersed in the oil to control passive oil loss. These nondigestible particles consist essentially of a cocrystallized blend of a nondigestible solid polyol fatty acid polyester hardstock and a crystal modifier capable of inducing this hardstock to form these relatively small particles. Edible fat-containing products comprising these nondigestible fat can be less waxy tasting due to the lower level of solids required for passive oil loss control.

  • Salad/cooking oil balanced for health benefits
    Patent number: 4948811
    Abstract: Triglyceride cooking/salad oil compositions with fatty acid content balanced for health purposes. The fatty acid composition of the triglycerides comprises by weight:Oleic: 60-92%Linoleic: 5-25%.alpha.-Linolenic: 0-15%Saturates: Less than about 3%At least about 20% of the triglycerides are triglycerides of mixed fatty acids.
