Vegetable oils (VOs), being our major dietary fat source, play a vital role in nourishment. Different VOs have highly contrasting fatty acid (FA) profiles and hence possess varying levels of health ...protectiveness. Consumption of a single VO cannot meet the recommended allowances of various FA either from saturated FA (SFA), monounsaturated FA (MUFA), polyunsaturated FA (PUFA), Ω-3 PUFAs, and medium-chain triglycerides (MCTs). Coconut oil (CO), flaxseed oil (FO), olive oil (OO), and sunflower oil (SFO) are among the top listed contrast VOs that are highly appreciated based on their rich contents of SFAs, Ω-3 PUFAs, MUFAs, and Ω-6 PUFA, respectively. Besides being protective against various disease biomarkers, these contrasting VOs are still inappropriate when consumed alone in 100% of daily fat recommendations. This review compiles the available data on blending of such contrasting VOs into single tailored blended oil (BO) with suitable FA composition to meet the recommended levels of SFA, MUFA, PUFA, MCTs, and Ω-3 to Ω-6 PUFA ratios which could ultimately serve as a cost-effective dietary intervention towards the health protectiveness and improvement of the whole population in general. The blending of any two or more VOs from CO, FO, OO, and SFO in the form of binary, ternary, or another type of blending was found to be very conclusive towards balancing FA composition; enhancing physiochemical and stability properties; and promising the therapeutic protectiveness of the resultant BOs.
With a continuous increase in population and economic development, the demand for high quality seed oils keeps increasing in China. In the last decades, many minor edible oils become increasing and ...popular.
In this review, the chemical composition and nutritional properties of minor edible oils, including flaxseed oil, corn oil, rice bran oil, camellia oil, safflower oil, almond oil, grape seed oil, walnut oil, perilla seed oil, pumpkin seed oil, evening primrose oil, Eucommia ulmoides Oliver seed oil, penoy seed oil, sea buckthorn seed oil, Acer truncatum Bunge seed oil, Torreya grandis seed oil and tomato seed oil, were summarized. The characteristic chemical compositions of these 17 kinds of minor edible oils were analyzed from fatty acid composition, phytosterols, tocopherols, total phenolic content, squalene and β-carotene contents.
Different types of vegetable oils have their own specific advantages and biological activities, and appropriate vegetable oils can be selected to meet individual needs accordingly. For example, Acer truncatum Bunge seed oil contains 5.52% nervonic acid (C24:1) that can promote the repair and regeneration of nerve cells and tissues damaged, while corn oil and rice bran oil have higher contents of campesterol and total phytosterol and might be therefore better choices for patients with high cholesterol and cardiovascular diseases. This review could benefit comprehensive understanding nutritional values of minor vegetable oils and future researches on nutrition and product development.

Well activation is one of the most important aspects in the oil and gas industries and nitrogen gas is predominately used. The gas, being light, is sent down the producing reservoir which will ...enhance the production or improve the flow of crude oil. In addition to the methods used to increase production there are several problems like sand production and water production from the producing wells.Sand production occurs when the destabilizing stresses at the formation face exceed the strength of the natural arching tendencies and/or grain-to-grain cementation strength. Ideally, during oil production, the formation should be porous, permeable and well consolidated through which hydrocarbons can easily flow into the production wells. But sometimes, especially during production from unconsolidated sandstone reservoirs, the produced hydrocarbons may also carry large amounts of sand into the well bore and sand entering production wells is one of the oldest problems faced by oil companies and one of the toughest to solve. These unconsolidated formations may not restrain grain movement, and produce sand along with the fluids especially at high rates.Water production is also a problem that many reservoir or production engineers face in day-to-day life. As engineers we should be able to decide whether water control solutions should be applied or not. The excess production of water is caused by the depletion of the reservoir and simply sweeps away most of the oil that the reservoir can produce.This book gives an information how well activation using nitrogen is carried out, and how sand control and water control issues can be resolved.

Extra virgin olive oil has been one of the most common targets for economically motivated food adulteration. This research employed the hand‐held FTIR spectrometer to develop the simple and portable ...screening methods for extra virgin olive oils adulterated with other cheaper vegetable oils. With the help of the ATR probe and chemometrics tools, oil samples can be measured directly without any pretreatment, then the spectra can be interpreted automatically to determine the possibility of adulteration and estimate the content of adulterant oil. A feasibility study of the hand‐held FTIR screening method was carried out using olive oils adulterated with canola oil, peanut oil, corn oil, soybean oil, and sunflower oil. The SIMCA model using the hand‐held FTIR spectra can identify different kinds of vegetable oils correctly and recognize olive oils with not less than 10% of adulterant oils. Meanwhile, the content of adulterant oil in the range of 5% to 45% can be estimated by the PLS model using the hand‐held FTIR spectra within an error of 3%. This research shows the potential of the hand‐held FTIR technique in the rapid and field screening of olive oils adulterated with some cheaper vegetable oils.
Practical Application
This research provide a rapid and automatic detection method for olive oils adulterated with other cheaper vegetable oils. An oil sample can be measured directly within one minute, and the hand‐held instrument can be used anywhere needed.
The Arab Spring holds the promise of improved living standards and a more prosperous future for the peoples of the Middle East and North Africa region. At the same time, the region is witnessing ...uncertainty and economic pressures from domestic and external sources, which will likely be exacerbated by the recent worsening of the global economy. The main challenge in the short term will be to manage expectations while maintaining economic stability. To that end, better-targeted subsidies and transfers will help free up resources for investment in infrastructure, education, and health. Policies aimed at fostering inclusive growth will also help cement the longer-term benefits of the ongoing changes in the region. In the Caucasus and Central Asia, the economic outlook is broadly positive. Exports and remittances--key growth drivers in 2010--are continuing to grow solidly, helping the recovery gain firm momentum. At the same time, uncertainties over the robustness of the global recovery constitute a downside risk to the growth outlook. Key challenges facing the region over the medium term are to create jobs and foster high and inclusive growth.
