In this study rainbow trout (Oncorhynchus mykiss) fillets were vacuum packed, frozen and stored at -18°C and  the effect of this packaging method on proximate composition, fatty acids and amino acid profile and their changes compared to control conditions during 9 months of storage were studied. The results showed that 18 fatty acids were identified. The unsaturated fatty acid (UFA) were 56.77 ...

The effects of grazed grass, grass silage, or concentrates on fatty acid composition and conjugated linoleic acid (cis-9, trans-11-18:2; CLA) concentrations of i.m. fat of steers fed to achieve similar carcass growth rates were investigated. Fifty steers were divided into 10 blocks based on body weight and assigned at random from within blocks to one of five dietary treatments. The experimental...

BACKGROUND Effects of major dietary macronutrients on glucose-insulin homeostasis remain controversial and may vary by the clinical measures examined. We aimed to assess how saturated fat (SFA), monounsaturated fat (MUFA), polyunsaturated fat (PUFA), and carbohydrate affect key metrics of glucose-insulin homeostasis. METHODS AND FINDINGS We systematically searched multiple databases (PubMed, ...

This paper investigates the possibilities of using two types vegetable oil emulsions as animal fat substitutes in cooked emulsified sausages. The sausage samples were made with full or partial substitution pork back emulsions. use oils meat formulations led to a reduction SFA/UFA ratio. PUFA/SFA ratio was improved where substituted chia (samples 2, 4 and 6), this most probably resulted from emu...

The study was aimed at assessing the effect of dietary supplementation with black pepper (Piper nigrum) on chemical and fatty acid composition in meat rainbow trout (Oncorhynchus mykiss W.), farmed a recirculating system.
 Rainbow were distributed two groups – experimental fed 1% powdered extract from (BPE) control (C) without extract. After end experiment, 6 fish each group euthanized, fi...

In the present study, we investigated the effect of long-acyl chain SFA, namely palmitic acid (16:0) and stearic acid (18:0), at sn-1, 3 positions of TAG on obesity. Throughout the 15 weeks of the experimental period, C57BL/6 mice were fed diets fortified with cocoa butter, sal stearin (SAL), palm mid fraction (PMF) and high-oleic sunflower oil (HOS). The sn-1, 3 positions were varied by 16:0, ...

Consumption of fish or fish oils rich in the n-3 long chain PUFA EPA and DHA may improve multiple risk factors for CVD. The objective of this study was to determine whether regular consumption of foods enriched with n-3 long-chain PUFA can improve n-3 long-chain PUFA status (erythrocytes) and cardiovascular health. Overweight volunteers with high levels of triacylglycerols (TG; >1·6 mmol/l) wer...

Phospholipids containing PUFAs are important vehicles for their delivering to the targeted tissues. In our research project we established enzymatic methods for the enrichment of natural egg-yolk PC with n-3 PUFAs. Instead of synthetic PUFA ethyl esters, the new strategy was developed using polyunsaturated fatty acids enriched fraction (PUFA-EF) from cod liver oil as the natural acyl donors. PU...

The objective of this study was to compare the fatty acid (FA) composition of intramuscular fat from the LM of 3 divergent breeds of cattle: Angus (AN, n = 9), Brahman (BR, n = 7), and Romosinuano (RM, n = 11). Cattle were blocked by breed and finished 129 d before slaughter in one year and 157 d in the next year. Longissimus muscle samples were collected from each carcass between the 10th and ...

To the Editor: Longitudinal studies suggest that nutrition plays an important role in healthy aging.1 As people age, eventually they become less active, theirmetabolism slows, and energy requirement and dietary intake decrease.2 At the same time, nutrient requirementsmayeven increase as the ability to absorb and utilizemany nutrients becomes less efficient, thus maintaining a nutrient-dense and...
