Abstract
The present invention is a composition of matter comprising an edible, wholly or partially nondigestible low calorie fat material having a non-Newtonian pseudoplastic rheology at body temperature. In particular, at 100.degree. F. (37.8.degree. C.) the fat material has: (a) a viscosity of at least about 2.5 poise at a shear rate of 800 seconds.sup.-1, a viscosity of at least about 4.0 poise at a shear rate of 100 seconds.sup.-1, and a viscosity of at least about 15.0 poise at a shear rate of 10 seconds.sup.-1 ; (b) a yield point of at least about 2,500 dynes/cm.sup.2 ; (c) a thixotropic area of at least about 0.20.times.10.sup.6 dynes/cm.sup.2 -sec.; and (d) a liquid/solid stability of at least about 50%. The composition is useful as a substitute for triglyceride fats in low calorie fat-containing food products, and as a method for reducing serum cholesterol. Examples of specific low calorie fat materials that can be used in this invention include sugar fatty acid polyesters, polyglycerol fatty acid polyesters, and tricarboxylic acids esterified with fatty alcohols.
