Patent number: 8361173Abstract: Provided herein are blends oils or fatty acids comprising more than 50% medium chain fatty acids, or the fatty acid alkyl esters thereof, and having low melting points. Such blends are useful as a fuel or as a starting material for the production of, for example, a biodiesel. Also provided genetically altered or modified plants, modified such that the amount of medium chain fatty acids generated by the plant are increased. Further provided is a method of predicting the melting point of a blend of fatty acid methyl esters and the use of such a method for identifying blends suitable for use as, for example, a biodiesel.Type: GrantFiled: September 7, 2011Date of Patent: January 29, 2013Assignee: Nucelis Inc.Inventors: Mark Knuth, Peter R.
