Patent number: 5451416Abstract: 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.

Patent number: 5124166Abstract: Novel fat mimetic compounds and their uses in food compositions are disclosed. These compounds comprise a backbone to which is attached one hydroxyl group acylated with a fatty acid, forming a pendant carboxy substituent (--O.sub.2 C--R', where R' is an aliphatic group having 1 to 30 carbons), and one carboxylic acid group esterified with a fatty alcohol, forming a pendant carboxylate substituent (--CO.sub.2 R', with R' as defined above).Type: GrantFiled: May 21, 1990Date of Patent: June 23, 1992Assignee: Nabisco, Inc.Inventors: Peter T. Jacklin, Ronald P. D'Amelia, Lawrence P. Klemann, John W. Finley
