Vegetable oils can be adjusted by different methods to enhance their commercial applications and to increase their pure quality nutrition. One of the most leisurely ways of creating new innovative products with desirable textured and oxidative properties is the mixing of vegetable fats/oils of various properties. Pure sunflower (SFO) blended with pure moringa (MOO) and sesame (SEO) oils in the ratio of 95:5 and 90:10 w/w. The outcomes showed that the highest acid value was observed at SFO + SEO 10% (0.782). Sunflower oil stabilized when blended with MOO and the levels of conjugated dienes (CD) and trienes (CT) were depressed compared to control. The TPC value was higher when the sunflower blended with moringa oil. The highest scavenging activity percentage was observed in SFO + MOO 5% and SFO + SEO 10% respectively. Meanwhile, the highest induction period at 100 °C was 11.45 hours in the treatment of SFO + MOO 5%. The master fatty acids in the sunflower and moringa oils are combined (SFO:MOO, 90:10), oleic, and palmitic acids. It seems from the current findings that suitable mixing of high linoleic oils with MOO will result in oil mixtures that can satisfy nutritional wants with expanded balance for home cooking and deep-frying.

To examine the role of NH3 on bundles of aligned bamboo-shaped carbon–nitrogen (C–N) nanotube were synthesized the pyrolysis of ferrocene (Fe(C5H5)2) and sunflower oil mixtures with NH3 being the source of nitrogen. The concentration of NH3 was varying in volume (vol). Optimized temperature and concentration of ferrocene were 825°C and 10 mg/ml, respectively. With the increase of nitrogen concentration the bundles are breaking in nearly equal parts. With nitrogen doping, the nanotubes have a bamboo-like structure and reveal degraded crystallinity of graphitic sheets. Nitrogen plays key role in generating equal compartments inside the carbon nanotube. The nanotubes were characterized by scanning electron microscopy and transmission electron microscopy that reveal the vertically aligned and hollow structural features of the nanotubes. FTIR shows the incorporation of N atom inside carbon framework and Raman spectrum indicates the enhancement of the defects inside C–N nanotube due to the N atom in C–N nanotube.

Cold Pressed

The aim of the study was to evaluate the stability of cold-pressed sunflower oil mixed with different seeds and herb. The seeds and herb were added at 1% and 5% concentrations; samples were divided into 2 groups: stored in the dark and light. The primary products of oxidation and chlorophyll content were monitored during 3 months of storage. The results showed very low oxidation stability of experimentally produced cold-pressed oil mixtures/dressings, especially during storage on the light. The samples with 5% of hemp herb addition showed the best stability since they have peroxide value under 20 mekv O2.kg-1, both in the dark and on the light. Other samples, both stored in the dark and on light, were declared as not for human consumption due to high oxidative product development. The research represents an important storability evaluation of products that can be found on the market and that can be found very attractive for consumers.

Wild Berries

Many species of forest plants in combination with vegetable oils are the sources of new types of functional products with increased biological efficiency. In respect that the high demand for vegetable oils among the population and industry, the growing anthropogenic pressure on various components of the natural environment, the goal of the research was to create oil mixtures based on sunflower oil and wild berries selected in the forest areas of Kazkhstan`s regions, assess their quality and food safety. The base of the oil mixture was sunflower oil obtained from sunflower seeds by the "cold squeeze" method. Wild berries selected from forest areas of northern (Elaeagnusrhamnoides (L.) A. Nelson) and eastern (Rosa majalisHerrm.,Vacciniummyrtillis L.) of Kazakhstan were used as bio-additives. In the obtained oil mixtures, the basic parameters of their qualitative and quantitative composition were studied. It was found that by density (917-918), refractive index (1,473), acid number (1,4 mg KOH/g), iodine number (130-132 g J2/100), saponification number (188 mg/g) of the tested oil mixtures they correspond to unrefined vegetable oil of higher grade. The content of heavy metals (Pb, As, Cd, Cu, Zn, Mg) and radionuclides (90Sr, 137Cs) does not exceed the maximum permissible concentrations and meets the requirements of regulatory documents and standards. In samples of vegetable oils, the amount of oleic acid (52,21%), linoleic acid (28,97%) is determined, which are within the normal range, although they are adjacent to the levels of the upper limits. NMR spectroscopy confirmed that the optimal ratio of ω-6 and ω-3 polyunsaturated fatty acids in the composition of the studied vegetable oils correspond to their name in the ratio of monounsaturated and polyunsaturated fatty acids.

Relationship Of

<p>This paper is written to show comparison between the naphthenic mineral oil with namely olive oil and sunflower oil in the context of voltage breakdown as insulating transformer oil. Olive oil is known to have been tested as alternative oil for transformer insulation and sunflower oil is a new oil being tested in this paper. The oils are mixed within certain ratios in order to determine the withstand breakdown voltages. The relationship of the breakdown voltages are also tied with the viscosity of the mixtures, and the mixture of oils are also exposed to ageing test and of tan-delta balancing test. All test follow IEC60156 standard test procedure for liquid insulation test. The mixtures were compared to the existing mineral oils and the findings will be discussed.</p>
