tea and sesame seed oils extracted by different methods (including supercritical fluid extraction (sfe), at a pressure of 350 atm, a temperature of 60oc, a static extraction time of 20 minutes, a dynamic extraction time of 30 minutes and 150 g kg-1 of ethanol as a modifier). solvent (se) and ultrasound-assisted solvent extraction (ue)), as natural anti-oxidants, were evaluated during 15 days st...

abstract: degumming and neutralization processes are two essential stages carried out on crude edible oils in order to remove some unwanted impurities namely gums and free fatty acids. in this research study two popular less expensive commercial oils that are consumed to a great extent namely soyabean and sunflower seed oils are selected and subjected to both degumming and neutralization proces...

Sunflower plant (Helianthus annuus) is a miraculous oil seed crop which is cultivated globally for its seeds. Sunflower seeds, a nutrient dense food has been found to have a potential role in chronic inflammatory conditions, bacterial and fungal infections, cardiovascular diseases, skin diseases and even cancers. These benefits of sunflower seeds are attributed to the presence of phytosterols, ...

Vidrih R., Vidakovič S., Abramovič H. (2010): Biochemical parameters and oxidative resistance to thermal treatment of refined and unrefined vegetable edible oils. Czech J. Food Sci., 28: 376–384. In human nutrition fats are physiologically important food constituents but also the components most liable to oxidative degradation. The oils included in the study were refined (sunflower, extra-sunfl...

bleaching process is an essential stage in the refining of vegetable oils and fats. in this process the colour and the primary and secondary oxidation products are removed by the treatment with the acid activated bleaching earth .the aim of this project is to understand the effect of bleaching on the physical characteristics and chemical constituents of neutralized canola and sunflower seed oil...

Let n ≥ t ≥ 3. Suppose that F is a family of t-element subsets of [n] satisfying |F| > ( n t−1 )t−1 + o(nt−1). Our main result implies that there exists a t-element subset S of [n] such that {E ∩ S : E ∈ F} contains all 2-element subsets of S, and this is asymptotically sharp. When t = 3, we prove the same result whenever |F| > ⌊ (n−1)2 4 ⌋ , which is sharp for all n ≥ 3. Our proofs use the Erd...

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...

The effects of dietary lipids on the abundance of dendritic cells in adipose tissue in anatomically defined relationships to chronically inflamed lymph nodes were investigated in mature male rats fed plain chow or chow plus 20 % sunflower-seed or fish oil. The popliteal lymph nodes were stimulated by local subcutaneous injection of 20 microg lipopolysaccharide to both hindlegs three times/week ...

This study describes an eighteen-year-old filly after an injury in the region of the dorsal left metatarsus, admitted to veterinary assistance. In addition to the normal treatment, which was characterized by cleaning and topical application of povidone-iodine, sunflower-seed oil was applied locally in order to improve and fasten wound healing. Macroscopic and clinical improvements of the wound ...
