Abstract: | An analytical study of the monoethylenic isomers in commercial samples of partially hydrogenated herring, whale and seal oils
is presented. The results show that with hydrogenated herring oil there is a slight decline in monoenetrans content from 37% in C16 through to 32% in C22. With both whale and seal oils, monoenetrans contents were constant at 54% and 59%, respectively, throughout all chain lengths. In general thecis andtrans positional isomers from hydrogenated whale and seal oils were more scattered than those from hydrogenated herring oil; however
in each oil the majorcis isomers of each chainlength were indicative of originalcis fatty acid isomers in the raw oils. |
