    3. Results and discussion 3.1 Nutritional analysis In the present study‚ the potential benefits were shown by nutritional attributes of dried bathua (Table1). Moisture content and dry matter analysis‚ reporting during nutritional analysis is very important because it directly affects the nutritional content of vegetable. The moisture content was quite low (5.06%) which may be advantageous in view of increasing the sample’s shelf life. Bathua was found to be rich in carbohydrates (40.84%). There

    (glycerides) and methanol are combined with sodium hydroxide as a catalyst. This causes the oils to break apart and reaction of the oils with the methanol. As seen in Figure 1‚ this produces biodiesel (in the form of esters) and glycerol. Figure 1: The production of biodiesel (esters) from glyceride (cooking oils) and an alcohol (methanol). In combustion‚ a substance can be completely or incompletely combusted. In complete combustion‚ a fuel is combined with oxygen to produce water and carbon dioxide

    used. IODIESEL consists of a mixture of fatty acid alkyl esters‚ that can be used as an alternative fuel in compression-ignition engines; it is obtained from renewable resources‚ such as vegetable oils and animal fats‚ which makes it biodegradable and non-toxic [1]‚[2]. Biodiesel might be produced by transesterification‚ which is a three-step reversible reaction that converts the initial triglyceride into a mixture of alkyl esters and glycerol‚ in the presence of a catalyst. Currently‚ biodiesel
