The effect of extraction methods, and deep-frying process on the Physico-chemical Properties of (shea oil) vitellaria paradoxa ssp.

The main goals of this research were to study the effect of extraction methods, and deep frying process on the Physico-chemical Properties of vitellaria paradoxa ssp. niloticabeside the chemical composition of shea nuts, the sensory evaluation of potato chips fried in shea butter, groundnut, and their blend oil (1:1) and finally the fatty acid profile of shea butter.

The samples were collected from Alradoum area Southern Darfour State – Sudan. Samples were well prepared and kept in deep freezer for further analysis. This study was evaluated the effect of both extraction methods (solvent and boiling) on the physical properties of shea butter concerning, their specific gravity, viscosity, refractive index and color intensity. The reported results for solvent extraction method were, (0.9410 at 30˚c (g/cm ), 1.1(CP), 1.47 and 3.57) were the obtained results for boiling extraction method were, (0.8901 at 30˚c (g/cm ), 3.6 (CP), 1.48 and 10.37) respectively. These findings indicated that, there was no significant difference (P0.05).
