background: autoxidation is considered to be the main route of edible oil deterioration, which produces undesirable odors and flavors (attributed to primary and secondary products of unsaturated fatty acids) during storage and heating. objective: antioxidant activities of zataria multiflora (zmeo) and bunium persicum (bpeo) essential oils (eos) in linseed oil (containing higher ω-3 in vegetable...

1. Six wether sheep were each provided with a permanent cannula in the rumen and re-entrant cannulas in the proximal duodenum. 2. In a preliminary study, the sheep consumed 200 g hay and 400 g concentrates supplemented with up to 40 g linseed oil, coconut oil or cod-liver oil daily. Feed was refused at higher levels of supplementation. 3. Five of the sheep were used in a 5 x 5 Latin-square expe...

Aim of study: To evaluate which vegetable lipid source promotes better growth performance, whole-body composition and fatty acid profile for juvenile giant trahira (Hoplias lacerdae).
 Area Fish Nutrition Laboratory the University Viçosa (UFV), MG, Brazil.
 Material methods: A 50-day feed trial with four treatments, consisting diets containing different sources (canola, linseed, soybe...

The fixed oil of L. usitatissimum (flaxseed/linseed) inhibited PGE2-, leukotriene-, histamine- and bradykinin-induced inflammation. The oil also inhibited arachidonic acid-induced inflammation, suggesting its capacity to inhibit both cyclooxygenase and lipoxygenase pathways of arachidonate metabolism. In tail immersion model, the oil raised the pain threshold to a lesser extent than morphine bu...

The optimization of a gelled oil-in-water emulsion was performed for use as fat replacer in the formulation of ω-3 PUFA-enriched cooked meat products. The linseed oil content, carrageenan concentration and surfactant-oil ratio were properly combined in a surface response design for maximizing the hardness and minimizing the syneresis of the PUFA delivery system. The optimal formulation resulted...

Some dietary factors could inhibit lead toxicity. The aim of this study was to evaluate the effect of dietary compounds rich in unsaturated fatty acids (FA) on blood lead level, lipid metabolism, and vascular reactivity in rats. Serum metallothionein and organs' lead level were evaluated with the aim of assessing the possible mechanism of unsaturated FA impact on blood lead level. For three mon...

Fatty acids of marine origin have been shown to affect blood coagulation in the rat. In an attempt to gain insight into the mechanisms of this phenomenon, we studied the effects of dietary linseed and fish oils on the liver antioxidant status and plasma coagulation parameters in rats on a time-course basis. Dietary enrichment in eicosapentaenoic and docosahexaenoic acids resulted in strong hypo...

An experiment was conducted to study the effects of soybean, linseed and sunflower oil (various sources of fatty acids) with and without L-carnitine supplements (0 and 50 mg kg-1) on performance, blood biochemical parameters and carcass traits of Japanese quail. One hundred and ninety-two of 7-day old female Japanese quail were randomly assigned to 6 dietary treatments with 4 replicates and fed...
