| dc.description.abstract | Watermelon fruit contains large quantities of seeds and the seed oil has got many benefits. In order to make effective and efficient utilization of seeds, in the present investigation the physical properties of watermelon and their seeds were measured. The oil from watermelon seeds was extracted using mechanical screw press and the oil content was estimated using Soxtherm apparatus which works on the principal of solvent extraction and found 38 % oil in the seeds. To optimize the effect of temperature and moisture content on oil recovery, factorial completely randomized design of experiments was employed and the oil was extracted at five different temperatures viz., 30, 40, 50, 60 and 70 ºC and moisture contents viz., 4, 6, 8, 10 and 12 %. The best combination for maximum oil recovery was observed to be at 10 % moisture content and 50 ºC temperature. As the watermelon seed oil is the renewable energy source, the extracted oil was converted into biodiesel and subjected to study for its quality parameters at five different levels viz., extracted crude oil, obtained biodiesel (B-100) and three different blends such as B-30 (30 % biodiesel:70 % diesel), B-20 (20 % biodiesel:80 % diesel) and B-10 (10 % biodiesel: 90 % diesel). The best performance for flash point, fire point, viscosity, free fatty acid value and calorific values were found to be 70 ºC, 80.50 ºC, 25.37 millipoise, 0.36 mg KOH/g and 43845.03 kJ/kg, respectively. | en_US |
