Positional distribution of fatty acids on hoki and tuna oil triglycerides by pancreatic lipase and13C NMR analysis

What is it about?

Fish oil contains bioactive omega‐3 fatty acids (DHA and EPA), however bioavailability and oxidative stability of these omega‐3 fatty acids depends on their positional distribution. Pancreatic lipase has been used in determination of positional distribution of fatty acids in fish oil, but this method involves heat and is time consuming and not suitable for fish oil with more than one molecule of PUFA in a single triglyceride. NMR has gained popularity in positional distribution determination of n‐3 fatty acids in fish oil as it is a rapid and non‐destructive method compared to the conventional chemical and enzymatic methods.
