Publication number: 20050159610Abstract: The present invention is directed to a process of producing polyol esters possessing desirable composition and color. Preferably, such a process does not require molecular distillations or decoloration steps to yield a light-colored polyol ester composition. Materials that are dark in color are often produced during the esterification of polyols with vegetable oil fatty acids. It has been discovered that the present process yields the desired ester products that are light in color. The present process comprises an esterification of a polyol, such as propylene glycol, and a fatty acid ester, such as a vegetable oil fatty acid methyl ester, in the presence of a catalyst and borohydride, wherein a polyol ester having a Lovibond color below about 0.6 Red and below about 1.5 Yellow is produced.Type: ApplicationFiled: January 16, 2004Publication date: July 21, 2005Inventor: George Poppe

Publication number: 20050038270Abstract: This invention pertains to the preparation of a sterol ester-enriched food ingredient utilizing a base-catalyzed tranesterification of free sterol with fatty acyl glyceride. Phytosterols are subject to transesterification with fatty acyl glyceride from vegetable oils in the presence of an alkali catalyst. The reaction is performed under vacuum in the range of 0.01-1 Torr. Following an initial period of transesterification, the reaction mixture is distilled to remove glycerol to enhance the formation of sterol esters. A sterol ester-rich fraction can be isolated from the reaction mixture using organic solvents in combination with aqueous washes.Type: ApplicationFiled: September 22, 2004Publication date: February 17, 2005Inventors: Brent Flickinger, Richard Grabiel, George Poppe

Patent number: 6723863Abstract: A process of producing a light-colored, high-monoester mixture from a polyol and an oil is provided wherein the process eliminates the use of organic solvents, multiple water washings and/or molecular distillation. The reactants, a polyol and an oil, described herein, condense in the presence of a catalyst, described herein, at a temperature range from about 180° C. to about 280° C. under an inert atmosphere or the vapor pressure of the polyol with a pressure of about 0 to about 500 psig to yield a monoester mixture possessing a desirable monoester composition and color. The present process yields a final product similar to that of processes which require the use of solvents, multiple water washings and/or molecular distillation.Type: GrantFiled: August 7, 2002Date of Patent: April 20, 2004Assignee: Archer-Daniels-Midland CompanyInventors: Inmok Lee, George Poppe
