  • Patent number: 5527866
    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.

  • Patent number: 5342642
    Abstract: This invention relates to a pie or pastry dough, which provides a flaky tender pie crust when baked. The product is a laminate of two phases, a dough like mixture of flour, water, salt and oil, and a shortening and starch phase. One or both phases can contain a polyol. These phases are laminated to make a heterogeneous pastry dough which has a flaky tender texture when baked. The dough is characterized by having multiple, discontinuous layers which are interrupted by regions of gluten and the starch/fat/polyol phase, an increased dough strength and less water absorption over 24 hours.

  • Patent number: 5334764
    Abstract: Amines such as methyl amine are reacted with materials such as reducing sugars in hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amines. Accordingly, glucose is reacted with methyl amine and the resulting adduct is hydrogenated to yield N-methylglucamine. The N-alkyl polyhydroxyamines can be subsequently reacted with fatty esters to provide polyhydroxy fatty acid amides useful as detersive surfactants. Thus, detersive surfactants are available from non-petrochemical precursors such as sugars and sugar sources such as corn syrup, and fatty acid esters derivable from various fats and oils.

  • Patent number: 5275835
    Abstract: An improved process is disclosed for preparing flavored confectionery compositions containing certain reduced calorie cocoa butter substitute fats. The improvement involves rapidly cooling such a composition from a non-crystalline state to a temperature of less than about 70.degree. F. (21.1.degree. C.) using a swept-wall, scraped-wall, or screw-type heat exchanger. The cooled composition is then conditioned for at least about 5 minutes by warming it to a temperature of about 70.degree. to 85.degree. F. (21.1.degree. to 29.4.degree. C.) in an agitated vessel before further processing into finished confectionery pieces. Under these dynamic tempering conditions, bloom-stable products can be produced much faster than with static tempering.
