Dear Rajendra I found it interesting that you mention on esterification that the chain length is broken from C18 or more down to a chain length of C11 - C13. Can such a difference be due to the variety of oil that is selected? The reason I ask is that I have been making BD from cold pressed virgin Canola oil, and I had a GC fatty acid analysis performed on my BD and the results were; C16:0 -C18:0-C18:1-C18:2-C18:3-C20:0-C20:1-C22:0 3.9 - 4.83 - 80.54- 9.29- 0.00 -0.37 - 0.00 - 1.07 The GC fatty acid composition dosn't show chain lengths as short as what you mention, but 98.56% of chain lengths are C18:2 or shorter. I would appreciate your comments. Regards Steven
