Introduction:
he separation of substances from natural materials to obtain standardized products plays a pivotal role in food technology. Traditionally organic solvents were used for extracting compounds from a mixture. It is hard to imagine that gases could also take over this challenge. However this process has been a reality on an industrial scale for several decades. To convert gasses into effective solvents a liquid like density has to be created by applying pressure. In the field of this high pressure technology supercritical CO₂ emerged as the most suitable solvent. CO₂ extraction is used particularly in the food and beverage sector due to its manifold advantages and areas of applications.
