Polyphenols are potent antioxidants that are particularly abundant in the Mediterranean diet, with olive oil being the main fat source. A number of investigations have reported that phenolic compounds found in dietary oils are antioxidants and could provide protective effects by inhibiting DNA oxidative damage. However, few studies have been published on the biological activity of vegetable oil...

The chlorophyll content of canola oil, especially when extracted from frost-damaged seed is high, and results in dull, dark brown oil unless very large quantities of bleaching clay are used. We found that treatment with phosphoric acid, under vacuum in the absence of moisture precipitates most of the chlorophyll. At 140°C 2400 mg/L phosphoric acid precipitated 98 % of the chlorophyll in canola ...

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...

This study was undertaken to determine the non-target impacts of rangeland grasshopper control using liquid bait formulations of insecticides (canola and corn oil as carriers of carbaryl, diflubenzuron, and malathion). The research was conducted on native rangeland in Wyoming under drought conditions. Three collection methods (pitfall traps, yellow sticky cards, and sweep nets) were used to est...

The objective of the study was to ascertain whether human health beneficial omega-3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) content in heart, kidney and liver can be enhanced by supplementing prime lambs with graded levels of canola and flaxseed oil. Health status of the lambs, as a consequence of the supplementation, was also investigated by examining their plasma metabolite...

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

To study factors controlling plasma cholesterol levels, the effect of dietary fat type on cholesterol synthesis was examined in 15 hypercholesterolemic subjects (low-density lipoprotein [LDL] cholesterol > 130 mg.dL-1) consuming over a period of 32 days (1) a baseline diet (36% kcal as fat: 15% saturated, 15% monounsaturated, and 6% polyunsaturated fat; 180 mg cholesterol.1000 kcal-1) and diets...

compounds derived from lipid oxidation endangering human health and lead to cardiovascular disease and cancer. the addition of antioxidants is effective in retarding the oxidation of lipids and lipid containing foods. due to the toxicological effects of synthetic antioxidants, decrease their use and replacing them with natural antioxidants. this study investigates antioxidant effect of pimpinel...

Abstract Inconel 600 is a Ni-based superalloy having exclusive properties like high strength and stability in harsh conditions. However, its accurate machining challenging via conventional cutting methodologies. As result, the use of electric discharge common precisely. But intrinsic issue overcut associated with traditional EDM limits appreciation alloy. Moreover, dielectric oil used releases ...

Background There has been an alarming increase in the dumping of Hong Kong’s municipal solid waste (MSW), predominantly food waste, in landfill (9,547 tonnes of MSW per day in 2013) [1]. One way of promoting an environmentally friendly method of minimising food waste is to turn the waste into energy by producing biodiesel from waste cooking oils. Biodiesel is a biodegradable fuel that can be ma...
