BACKGROUND Lipid oxidation is a main problem during food processing, storage and consumption leading to losses of quality, stability, safety and nutritive value. Antioxidants have been used to prevent oxidation changes and off - flavor development in food products. Aim of the research was to evaluate antioxidative effect of thyme ethanol extract on sunflower oil during its storage in different ...

AIM Dietary fats may affect coronary artery disease risk by influencing factors other than serum cholesterol. The effect of diets containing coconut oil and sunflower oil without cholesterol supplementation on oxidative stress and lipid peroxidation were studied in male New Zealand White rabbits. METHODS Animals assigned to four groups (control, cholesterol-fed, coconut oil-fed and sunflower ...

Sunflower (Helianthus annuus L.) oil remains under-utilised albeit one of the major seed oils produced world-wide. Moreover, the high oleic sunflower varieties make the oil attractive for applications requiring high temperature processes and those targeting the C=C double bond functionality. Herein an overview of the recent developments in olefin metathesis of sunflower-based feedstocks is pres...

OBJECTIVE Although key roles for dietary vitamin E (VITE) and fatty acid (FA) in fertility have been confirmed, limited data are available on the effects of VITE alone, or a constant level of VITE supplemented by dietary omega-6 and omega-3 FAs in combination on male reproduction. Consequently in this paper, the effects of VITE, sunflower oil, fish oil and their combination on rat sperm were in...

Sunflower (Helianthus annuus L.) grain and oil quality are defined by grain weight and oil percentage, oil fatty acid composition and the amount of antioxidants. The aim of this work was to establish and validate a simple model, based on published relationships, which can estimate not only yield and its components, but also grain and oil quality aspects which are of relevance for industrial pro...

The effects on aortic and platelet fatty acid compositions and on blood levels of prostacyclin and thromboxane A2 of low- and high-fat diets containing olive oil or sunflower oil were studied. For 4 weeks, four groups of weanling rats were fed a basal diet containing 5% or 25% olive oil or sunflower oil. Rats fed olive oil diets showed higher levels of 18:1(n-9) and polyunsaturated fatty acids ...

The study is about measuring the unsaturated fatty acids, as well as, Omega acids by using GC/Mass in addition to HPLC extract and measure of some Iraqi local nurtures. Concentrated extracts linseed oil, sunflower butter, black seed, and, extracted oil Carp fish were measured. results are shown tables 6 7.Calcium, Potassium, Iron, Zinc, Magnesium rates into oils measured Atomic Absorption appar...

Natural oils are advocated and used throughout the world as part of neonatal skin care, but there is an absence of evidence to support this practice. The goal of the current study was to ascertain the effect of olive oil and sunflower seed oil on the biophysical properties of the skin. Nineteen adult volunteers with and without a history of atopic dermatitis were recruited into two randomized f...

Introduction. Edible oils containing > 60 % monoenoic acids (i. e. oleic acid), in particular olive oil and Canola oil have been shown to exhibit beneficial effects on lipid metabolism in human (LDL-cholesterol blood levels, triacylglycerol blood levels) within the last few years [1]. These findings are in contrast to earlier recommandations by nutrition experts who strongly favored high-linole...

We studied and quantified the elimination of sunflower oil from a wastewater influent using a biological treatment by activated sludge. Estimation of the biodegraded material was obtained doing a mass balance, and we conducted a follow-up of the different operational parameters and design. We delivered information about the operation of a system for treatment by activated sludge fed with an inf...
