| Abstract | Tuna heads, by-products from canned tuna industry, areused as raw materials for processing fish oils.Lipid composition of tuna head is a good source of beneficial fatty acids,especially Eicosapentaenoic acid (EPA)and Docosahexaenoic acid (DHA). They are the importantkeysof fish oil quality. The proposeof this research work was aimed to determine the fatty acid composition in the heads of three different tuna species (Katsuwonus pelamis, Thunnus tonggol, and Euthynnus affinis) collected from canned tuna industry in SamutSakhon Province, Thailandin different seasons. The results showedthat high quality tuna oil processed from E. affinissample caught between February and May had the highest contents of PUFA with 46.25% and 28.86% of DHA contents (p<0.05). The percentageof major fatty acids composition of tuna headspredicted by regression correlation from the fatty acid profiles over three different periods between 2014 to 2015 from Februaryto May, from June to September, and from October to January were used to study seasonal variation. The spawning season of tunas(October to January) gave the lowest DHA, Omega-3 and PUFA compositions compared to the other two periodsof time. |
