摘要

Mechanical pressing and subsequent solvent extraction of oil cake, succeeds in extracting most of the oil from sunflower seeds, peanuts and olives. Consumer demand for specialised oils such as avocado, evening primrose and grape seed is increasing and to produce these specialised oils requires a technique such as Supercritical Fluid Extraction, in order to yield a high quality product. The triglycerides from destoned, dried avocado fruit were extracted with unmodified supercritical carbon dioxide. The extraction rate was found to be influenced, not only, by fluid flow rate, temperature, pressure and particle size but is strongly by the degree of entrainment in the fluid stream.
