Abstract
Little information exists on recovering polyunsaturated fatty acids fr om microalgae; however, methods for concentration and purification of PUFAs from fish oil have been extensively reported. This review examin es recovery and purification of microalgae derived PUFAs, but techniqu es developed for use with fish oil are also reviewed as being potentia lly useful for concentration and purification from microalgae. The two main techniques for concentrating and purifying-urea fractionation an d high performance liquid chromatography-are discussed in depth and at tention is focused on the process developed by the authors for obtaini ng highly pure PUFA. Other potentially useful techniques, such as supe rcritical fluid extraction and lipase-catalyzed processing are detaile d. (C) 1998 Elsevier Science Inc.
