Biodiesel, fatty acid methyl esters derived from vegetable oils, is a well-established alternative to petroleum diesel. We have developed a rapid H diffusion-ordered nuclear magnetic resonance spectroscopy (DOSY NMR)method to resolve mixtures of mono-, di-, and triacyglycerols alongwith their methyl esters. Because of the differences in diffusion coefficients between the starting materials (tri...

A method for the determination of fatty acids in vegetable oils by capillary electrophoresis with indirect UV-vis detection has been developed. The separation of fatty acids was optimized in terms of Brij surfactant nature and concentration and organic modifier (2-propanol) percentage. The optimal background electrolyte consisted of 10 mM p-hydroxybenzoate, 5 mM Tris at pH 8.8, 80 mM Brij 98, 4...

Background and Objectives: Previous research has established that Vitamin D3 (Cholecalciferol) deficiency is considered to be a highly prevalent nutritional problem worldwide. Data from National Food and Nutrition Surveillance Program (2015) revealed that prevalence of vitamin D3 deficiency in Iran is more than 70% of the population. Vegetable oils are considered to be potential candidates for ...

The solvent extracted vegetable seed oils of Cucurbitaceae family viz. Bitter gourd (Momordica charentia), Small bitter gourd (Momordica dioica), Bottle gourd (Lagenaria siscraria) and Ridge gourd (Luffa acutangula) were evaluated as grain protectant against callosobruchus chinensis on the stored legume-pulse grains. All the vegetable seed oils were found effective as legume-pulse grain protect...

A precise and selective liquid chromatographic procedure for determining tocopherol and tocotrienol isomers in vegetable oils, formulated preparations, and biscuits was developed and validated. The proposed method quantitates vitamin E in better conditions of recoverability and reproducibility than the standard saponification procedure. Tocopherols and tocotrienols were extracted in hexane from...

The purpose of this project research is focused on the study of surface roughness and chip formation during milling operation of Mild Steel using vegetable based oil as a lubricant. Experimental set up designed by using milling machine. Taguchi Method of Orthogonal Array with factorial design of experiments used to analysis the response. Surface roughness and chip formation predicting models wa...

Vegetable oil fundamentally differs from other available products in its composition, ingredients and properties. Ensuring food security adapting to the requirements of a modern market economy is an important urgent problem. Particular attention this direction paid vegetable oils. Therefore, it conduct scientific research improve quality refined colored oils, as well safety. The paper recommend...

Fats and oils are chemically diverse group of compounds, which have the highest energy density among all macro nutrients. Besides having high caloric values, they are major sources of essential fatty acids (Ω-3 and Ω-6), fat soluble vitamins (A, D, E and K) and lecithin. Moreover, supplementation of fats and oils to poultry rations increases the metabolizable energy of the total ration, the cal...
