چکیده

One of the promising types vegetable raw materials in Ukraine, which can be used for development resource-saving technologies, are oils. The products their processing serve as obtaining surface-active substances, production food additives, pharmaceutical products, detergents and cosmetics, biofuels additives. most common oil Ukraine is sunflower, which, like other oils, processed to form fatty acids salts. initial process hydrolysis. technological parameters sunflower hydrolysis under different conditions were studied. It was investigated that alkaline presence sodium hydroxide proceeds fastest comparison with thermal methods sulfuric acid superheated steam, conversion reaches 100 % 25th minute experiment, at a temperature 60 °C. waste this glycerol solution, obtain its esters purpose implementing zero-waste technology scheme. A method using proposed, consists esterification acetic acid, result triacetin formed – valuable product use many sectors national economy. In industry, known additive code E1518, humectant stabilizer preserve freshness, plasticizer binder thickener, solvent odor fixer. Due ability broken down into components absorbed without any side effects human body, safe use. reaction between solution glycerin water took place %, while selectivity target remained constant level 80 %. At same time, concentration did not affect either amount or value selectivity. As catalyst process, p-toluenesulfonic relatively small 1.0 by volume, so it significantly composition this, future, makes possible conduct additional purification from traces catalyst.

Aflatoxin B1 contamination in sunflower oil collected from sunflower oil refinery situated in Karnataka

In the present study, the aflatoxin B1 contamination at various stages of oil refining and in refined oil were carried out. This was subsequently compared with commercial vegetable oil samples. Among the 23 different sunflower oil samples were tested, 10 of them showed positive results to AFB1 and the remaining 13 showed negative results to AFB1. All the refined oil samples were free from AFB1 ...

New natural injection-moldable composite material from sunflower oil cake.

Through a twin-screw extrusion process the native structure of sunflower oil cake was completely transformed (globular protein denaturation/texturization and husk fiber defibration) into a simpler matrix-fiber structure, as could be seen on SEM micrographs. Further chemical reduction of protein disulfide bridges greatly reduced the melt viscosity of the moistened composite that it could be inje...

Olive oil, high-oleic acid sunflower oil and CHD.

The low levels of CHD morbidity and mortality in Mediterranean regions is partly attributed to dietary factors. Olive oil is a key component of the traditional Mediterranean diet, therefore there has been intensive investigation to determine how olive oil mediates this effect. CHD has a very complex pathophysiology characterised by atherosclerosis, which is the result of aberrant lipoprotein me...
