The principles of extraction are quite simple and frequently used in our daily lives. When you brew a pot of coffee or make a cup of tea, the principles of chemical separation are occurring where you are splitting compounds such as the aroma, flavor, and nutrients from the organic matter. In chemistry, extraction consists of removing desired and sometimes undesirable constituents from a given matrix via a chemical or physical mechanism. There are several methods of extraction including but not limited to liquid-liquid, solid phase, supercritical & subcritical fluid, ultrasound- & microwave- assisted and solventless mechanical extraction.
