The sourcing ingredient is cleaned and potentially also washed. Then, it’s about extraction which can happen in a number of ways. Solvent extraction, steam distillation, and supercritical fluid extraction are just some of the methods to do it. For example, in solvent extraction, the sourcing ingredient is immersed in ethanol or water which then is subject to heat or stirring of the solution. After that, it’s purified through filtration and possibly other forms of purification. Then, evaporation or vacuum distillation can be applied to increase the concentration of the bioactive compounds. Then, standardization can also take place (a step that basically adjusts concentration). Finally, it’s processed and formulated into whatever form is required (be it liquid, powder, or oil-based extract). |
