they should immediately start to drink and eat. A dense starter feed, high in energy and protein (with appropriate amounts of lysine and threonine), highly digestible for young chicks, is essential to reach target bodyweight. The high energy content of a starter diet should never be achieved by adding fat or oil containing saturated fatty acids, because young chicks cannot digest them. Vegetabl...

Background: Previously, we showed that vegetable oil is necessary for carotenoid absorption from salad vegetables. Research is needed to better define the dose effect and its interindividual variation for carotenoids and fat-soluble vitamins.Objective: The objective was to model the dose-response relation between the amount of soybean oil in salad dressing and the absorption of 1) carotenoids, ...

Vegetable oils are a class of natural products very frequently used in phytocosmetology. Natural remedies with antiaging action are very popular in our days. Harmfulness of natural compounds on the skin, is quickly observed by the 24-48 hour patch test skin irritation and erythema measurement. Changes in the concentration of melanin and sebum in the dermis, represent real parameters which give ...

Compression ignition engine is a popular prime mover in rural areas, particularly in the places where electrical power is not available. The rapid depletion of fossil fuel has stimulated worldwide efforts to produce alternative fuel to diesel fuel. Use of bio fuel as an alternative fuel can contribute significantly towards the twin problem of fuel crises. The fuel of bio origin may be the bio d...

OBJECTIVE Long-chain n-3 fatty acid intake in Colombia is low because fish consumption is limited. Vegetable oils with high n-3 fatty acid content are recommended, but their concentrations of trans fats were high in previous studies. Thus, regular monitoring of the fatty acid composition of vegetable oils is required. Our objective was to quantify the fatty acid composition in commercially avai...

The adulteration of extra virgin olive oil with cheaper oils is a major problem in the olive oil market. In the present work, experimental determinations of low cost vegetable oils content in extra virgin olive oils (EVOO) were performed by Fourier Transform Infrared (FTIR) spectrometry and Raman spectrometry. To this purpose, a set of pure oils and mixtures of extra-virgin oils and different v...

Nickel nanoparticles have been synthesized using nickel nitrate, vegetable oil and sucrose. Ethanol has been used as a solvent since the heat of reaction shows the destabilization of nickel particles if water is present in the synthesis mixture. Nickel with fcc phase is obtained by reduction with sucrose followed by stabilization using vegetable oil. Nickel or possibly nickel carbide with hcp s...

erythromycin production is clearly enhanced by the addition of vegetable oils. however,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. the non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. in this research, sub-fractions of soybeanoil, including le...

Epidemiological studies have shown that increased dietary intake of natural antioxidants is beneficial for health because of their bioactivities, including antioxidant and anti-inflammation actions. Camellia oil made from tea seed (Camellia oleifera Abel.) is commonly used as an edible oil and a traditional medicine in Taiwan and China. Until now, the camellia oil has been widely considered as ...

Biodiesel is usually produced from food-grade vegetable oils that are more expensive than diesel fuel. Therefore, biodiesel produced from food-grade vegetable oil is currently not economically feasible. Waste cooking oils, restaurant grease and animal fats are potential feedstocks for biodiesel. These inexpensive feedstocks represent one-third of the US total fats and oil production, but are cu...
