Recent developments in Fourier transform infrared (FT-IR) spectroscopy instrumentation extend the application of this technique to the field of food research, facilitating particularly the studies on edible oils and fats. In this work, FT-IR spectroscopy is used as an effective analytical tool in order: (a) to determine extra virgin olive oil adulteration with lower priced vegetable oils (sunfl...

In a refrigeration cycle, some of the oil circulates and resides in cycle components. The worst scenario of oil circulation in the cycle is where a large amount of oil is retained outside the compressor. High oil retention causes system performance and reliability degradations. The purpose of this study is to experimentally clarify oil retention and pressure drop characteristics due to the pres...

The interactions between bees that depend on floral oil for their larvae and flowers that offer oil involve an intricate mix of obligate and facultative mutualisms. Using recent phylogenies, new data on oil-offering Cucurbitaceae, and molecular-dating, we ask when and how often oil-offering flowers and oil-foraging bees evolved, and how frequently these traits were lost in the cause of evolutio...

Three growth trials and one digestion trial were conducted to compare the effect of dietary fat sources and combinations on starter pig performance, nutrient digestibility and intestinal morphology. Growth trials 1 and 2, utilizing a total of 324 weanling pigs (21 +/- 3 d), were conducted to determine the influence of addition of soybean oil, coconut oil, choice white grease, 50% soybean oil: 5...

Abstract—The aim of this study was to determine the effect of oils on chemical, physical, and sensory properties of deep-fried dough stick. Five kinds of vegetable oil which were used for addition and frying consist of: palm oil, soybean oil, sunflower oil, rice bran oil, and canola oil. The results of this study showed that using different kinds of oil made significant difference in the qualit...

We investigated the effect of olive oil, rapeseed oil, and sunflower oil on blood lipids and lipoproteins including number and lipid composition of lipoprotein subclasses. Eighteen young, healthy men participated in a double-blinded randomized cross-over study (3-week intervention period) with 50 g of oil per 10 MJ incorporated into a constant diet. Plasma cholesterol, triacylglycerol, apolipop...

The effect of fish oil and corn oil supplementation on plasma lipids and lipoproteins and on low density lipoprotein (LDL) oxidation was examined in 20 treated hypertensive subjects. The randomized double-blind crossover study consisted of two 6-week interventions with 4 g/day of a highly purified fish oil or corn oil. Fish oil significantly (-24%, P < 0.01) reduced plasma triglyceride, and inc...

The coconut oil, coconut water and palm kernel oil was administered orally at a dose of 400mg/kg body weight to white albino rats to check for some effect on biochemical parameters. Twenty (20) rats divided into four (4) groups of five (5) rats each. One group was treated with distilled water and feed only serving as control, second group was treated with coconut water only while the third grou...

There has been much attention paid to oil security in China in recent years. Although China has begun to establish its own strategic petroleum reserve (SPR) to prevent potential losses caused by oil supply interruptions, the system aiming to ensure China's oil security is still incomplete. This paper describes and provides evidence for the benefits of an auxiliary strategic oil policy choice, w...
