For processing less than thirty tones of oil per 24 hours, and when oil has F.F .A. Based on the Soxhlet methods by Randall, the DET-GRAS-N extracts fats (and or other substances) from the sample by dis-solving them in a solvent. Historically, a number of methods have been developed for the analysis of fats in various food products.
The cooking oils that we use come primarily from nuts and seeds. The values of PV and p-AnV significantly differed depending on the extraction methods and shells.We measured the AV of oils obtained by different extraction methods by cold solvent indicator titration. Jadhav et al. Several researchers have shown that supercritical fluid extraction (SFE) could replace solvent extraction methods in a large variety of samples. There are many extraction methods, among which cold and hot extraction are conventional extraction processes. 5. This method takes a comparatively short time and is usually extracted in the laboratory using a fat extractor (Soxhlet extractor). For instance, fats and oils are the most concentrated form of energy, providing approximately 9 kcal of energy per gram compared to only 4 kcal per gram for proteins and carbohydrates (Ali et al., 2005). Shea butter is used as table oil due to its high nutritive value (Okullo et al., 2010; Olaniyan and Oje, 2007).It also finds use as a non-orthodox traditional plant used for the treatment of leprosy and other ailments in Nigeria and other Africa countries. The physicochemical properties (refractive index, saponification value, percent free fatty acid content, iodine value, acid value, peroxide value, melting point, moisture content, hydroxyl value, unsaponifiable matter and ash .
