The aim of the investigation was to determine the changes in fatty acids profile and chemical quality indexes of Red Tilapia fillets during frozen storage at -18°C. The fish were filleted by hand. The prepared fillets were then placed to the polyamide pouches and stored at -18°C for 150 days. Fatty acid profile, sensory properties and chemical quality indices were determined for a five month pe...

The aim of this study was to characterize the tissue-associated differences in the fatty acid profiles of intramuscular, subcutaneous and hepatic lipids and their quality indices from Lithuanian indigenous wattle pig and wild boar backcross to lean breed. The samples from hybrid pigs (1/4 Lithuanian indigenous wattle, 1/4 wild boar and 1/2 Landrace) were used in the experiment. There was little...

Edible insects may be a source of long-chain polyunsaturated fatty acids (LC-PUFA). The aim of this article is to test for differences in aquatic and terrestrial insects used in human nutrition. We implemented linear models and discovered that differences in the proportion of LC-PUFA between aquatic and terrestrial insects do exist, with terrestrial insects being significantly richer in particu...

The long-chain polyunsaturated fatty acids, arachidonic (AA) and docosahexaenoic acid (DHA), are essential structural lipid components of biomembranes. During pregnancy, long-chain polyunsaturated fatty acids (LC-PUFA) are preferentially transferred from mother to fetus across the placenta. This placental transfer is mediated by specific fatty acid binding and transfer proteins. After birth, pr...

Effects of butter and 2 types of margarine on blood lipid and lipoprotein concentrations were compared in a controlled diet study with 23 men and 23 women. Table spreads, added to a common basal diet, provided 8.3% of energy as fat. Diets averaged 34.6% of energy as fat and 15.5% as protein. Each diet was fed for 5 wk in a 3 x 3 Latin-square design. One margarine (TFA-M) approximated the averag...

There is controversy about the effect of saturated and polyunsaturated fats on 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase, the main regulatory enzyme of cholesterogenic pathway. Results from dietary studies are difficult to interpret because diets normally contain a mixture of fatty acids. Therefore, we have used Reuber H35 hepatoma cells whose phospholipids were enriched in different i...

MODULATION OF LIPOPOLYSACCHARIDE-STIMULATED ADIPOKINE SYNTHESIS AND SECRETION BY N-3 AND N-6 POLYUNSATURATED FATTY ACIDS Mary Margaret Cranmer-Byng Advisor: University of Guelph, 2013 Dr. Lindsay E. Robinson Dysregulation of adipokines in obese adipose tissue contributes to inflammation and insulin resistance. Fatty acids and lipopolysaccharide (LPS) can modulate adipokine secretion, however, l...

The composition of fatty acids in the diets of both human and domestic animal species can regulate inflammation through the biosynthesis of potent lipid mediators. The substrates for lipid mediator biosynthesis are derived primarily from membrane phospholipids and reflect dietary fatty acid intake. Inflammation can be exacerbated with intake of certain dietary fatty acids, such as some ω-6 poly...

Received: 30/01/2014 Revised: 25/02/2014 Accepted: 02/03/2014 Abstract Polyunsaturated fatty acids (PUFA) are getting more attention due to their role in human health. Nowadays, a growing awareness of health benefits of omega-3 (ω-3 or also referred as n-3) fatty acid has been found. Present overview provides importance, source and different methods used for the production of PUFA concentrates....
