Patent number: 7722909Abstract: The present invention relates to a method of preventing or reducing oxidation of a frying oil during frying. The method involves adding a terpene ester compound, including a terpenol esterified to a fatty acid, to a frying oil under conditions effective to prevent or reduce oxidation of the frying oil during frying. Also disclosed are frying oil compositions containing a frying oil and a terpene ester compound including a terpenol esterified to a fatty acid, as well as food products fried with such frying oil compositions.Type: GrantFiled: May 10, 2005Date of Patent: May 25, 2010Assignee: Iowa State University Research FoundationInventors: Pamela J.

Patent number: 6965044Abstract: A method for converting free fatty acids in acid oil or acid fat into fatty acid methyl esters is disclosed. The method involves adding a small amount of methanol and an acid catalyst to the acid oil or acid fat and subjecting the mixture to conditions that allow the fatty acid methyl esters to form. A lipid phase containing the fatty acid methyl esters and triglycerides can from and be separated from the rest of the reaction mixture. The lipid phase can then be subjected to conditions suitable for converting the triglycerides into fatty acid methyl esters. The method of present invention is especially useful for a process of generating biodiesel using a starting material of vegetable and animal oils and fats that contain a relatively high level of free fatty acids.Type: GrantFiled: July 5, 2002Date of Patent: November 15, 2005Assignee: Iowa State University Research FoundationInventors: Earl G. Hammond, Tong Wang

Patent number: 6133509Abstract: Soybeans (i.e., Glycine max L. Merr.) possessing a novel genetic determinant for the reduced production of linolenic acid in the endogenously formed vegetable oil of the seeds are provided. Such genetic determinant is the homozygous recessive fan3fan3 gene pair that has been found to be capable of formation through mutagenesis. Once formed, such genetic determinant can be readily transferred to other soybean lines and cultivars where it is similarly expressed on a reliable basis under conventional field growing conditions. In a preferred embodiment a soybean plant possesses the combined presence of the homozygous recessive gene pairs (1) fan1fan1 or fan1(A5)fan1(A5), (2) fan2fan2, as well as (3) fan3fan3 for reduced linolenic acid formation in the seeds and has been found that an unusually low expression for linolenic acid production in the resulting vegetable oil of the seeds is provided that is less than 1.3 percent by weight and most preferably is no more than 1.Type: GrantFiled: August 25, 1998Date of Patent: October 17, 2000Assignee: Iowa State University Research Foundation, Inc.Inventors: Walter R.

Patent number: 6060647Abstract: Soybeans (i.e., Glycine max L. Merr.) possessing a novel genetic determinant for the enhanced production of palmitic acid in the endogenously formed vegetable oil of the seeds are provided.
