Indirect Heating

EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) content in common fresh water fish : mujahir (Oreochromis mossambicus) after indirect heating were analysed. The aims of this study were to determine the effect of indirect heating process and α-tocopherol additions on both fatty acid stability.Lipids content in the mujahir fillets were extracted by Folch method using chloroform-metanol (2:1) mixture. Fatty acids in fish oil were converted to fatty acid methyl esters and then injected into gas chromatography to determine the EPA and DHA concentration. Operating condition of gas chromatography were programmed as follows: injection port temperature at 270 oC, detector at 280 oC, initial column temperature at 200 oC, and the final at 280 oC, the carrier gas was helium with flow rate of 10 ml per minute and temperature of column was increased gradually at 10 oC per minute. The effect of α-tocopherol addition on the stability of EPA and DHA was studied by adding α-tocopherol at 50 to 200 mg per kilogram sample before indirect heating process was carried out.The analysis of mujahir fish oil showed that the content of EPA and DHA in 100 grams fresh sample was 105 and 406,5 mg respectivelly. Indirect heating caused the EPA and DHA content decreased significantly. The addition of α-tocopherol results in a positive corelation between α-tocopherol concentration added and the decrease of EPA and DHA content during the heating process.   Keywords: fatty acid, eicosapentaenoic acid, docosahexaenoic acid

Hypertrophic Changes

A growing body of evidences report the cardiovascular benefit of fish oil including eicosapentaenoic acid (EPA) in humans and experimental animals. While many studies link EPA to cardiac protection, the effect of EPA on endothelin (ET)-1-induced cardiomyocyte hypertrophy is unknown. On the other hand, the previous study demonstrated peroxisomal proliferator-activated receptor (PPAR) -α ligand (fenofibrate) prevents ET-1-induced cardiomyocyte hypertrophy. Though EPA is one of the lignads of PPAR-α, there was no study linking relationship between EPA and PPAR-α on hypertrophied cadiomyocyte. The present study investigated whether ET-1-induced cardiomyocyte hypertrophy could be prevented by the pre-treatment of EPA. Cardiomyocytes were accumulated from neonatal rat heart, cultured and at day 4 of culture, the cardiomyocytes were divided into three groups: control, ET-1 (0.1nM) treated and EPA-pre-treated (10μM) ET-1 groups. A 90% increase in cardiomyocyte surface area, a 75% increase in protein synthesis rate and an elevated actinin expression in cardiomyocyte were observed after ET-1 administration and these changes were greatly prevented by EPA pre-treatment. ET-1-induced hypertrophied cardiomyocytes showed a 2.3-fold and 2.1-fold increase in ANP and BNP mRNA expression, respectively, which were also suppressed by EPA pre-treatment. Pre-treatment of EPA could also attenuate phosphorylated JNK (an important component of MAPK cascade), c-Jun and PPAR-α in ET-1-induced hypertrophied cardiomyocytes. In conclusion, the present study showed that ET-1 can induce significant hypertrophic changes in cardiomyocytes with upregulation of important hypertrophic markers, and that this remodeling was effectively prevented by the pre-administration of EPA through suppressing PPAR-α, phosporylated JNK, and c-Jun.

Fa Composition

The present study evaluated the effects of wash-out on the fatty acid (FA) composition in the muscles of Mediterranean yellowtail. After 109 days during which fish were fed either a fish oil (FO)-based diet (FO 100) or a diet (FO 0) in which FO was completely substituted by vegetable oils, all fish were subjected to a wash-out with FO 100 diet for 90 days. The FA profile of muscles in fish fed FO 0 diet at the beginning of the experiment reflected that of dietary vegetable oils, rich in linoleic acid (LA), and α-linolenic acid (ALA), and was deficient in AA (arachidonic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid). No essential FA were fully restored in fish previously fed FO 0 diet on 45th or 90th day of wash-out. At the end of wash-out, the FA composition showed that AA, EPA, and DHA in the white muscles increased by +33%, +16%, and +43% (p < 0.001), respectively. Similarly, AA and DHA in the red muscles increased by +33% and +41% respectively, while EPA remained similar to fish fed FO 0 diet exclusively. Therefore, a 90-d wash-out can partially improve the FA profile in muscles of Mediterranean yellowtail previously fed vegetable oil-based diets.
