The extraction method chosen must be fast, inexpensive, versatile and efficient and should have anease performance and no toxicity. The most widely used method for extracting capsaicin is based on extraction with hexane, which is very toxic and produces residual solvent.[10,11,12]

4.5: Extraction Theory

In a multiple extraction of an aqueous layer, the first extraction is procedurally identical to a single extraction. In the second extraction, the aqueous layer from the first extraction is returned to the separatory funnel (Figure 4.16b), with the goal of extracting additional compound. Since the organic layer from the first extraction had ...
