Abstract

Eating much fish has long been encouraged to prevent heart diseases and strengthen human health; however, there has been still a wonder why fish brings to people the wonderful usefulness like that. It's because of Omega-3 fatty acid found in fish. This famous micro-element helps prevent certain chronic diseases such as heart disease and arthritis, reduce cholesterol, and regulate blood pressure as well. Therefore, it's highly necessary to determine Omega-3 fatty acid in fish. In this paper, we use the method of the FT-IR Spectroscopy and the GC-MS to determine Omega-3 fatty acid in basa fish which are now popularly being fed in the area of Mekong-delta. The research results are compared with the different authors' works.
