Extraction Technologies for Functional Lipids

Sammanfattning

Algal functional lipids are a group of compounds that have recently attracted a lot of interest both from a scientific and an economic point of view. Microalgae are particularly rich in functional lipids such as omega-3 polyunsaturated fatty acids and carotenoids. These interesting compounds are often tightly entrapped inside the algal cells; hence they need to be extracted to be collected. Generally extraction can include different steps such as pretreatment (dehydration, cell disruption), extraction, and post-treatment (separation/fractionation). Extraction methods can be divided into conventional and nonconventional or novel methods. Conventional methods are based on traditional organic solvents, while novel methods include new greener and environmentally friendly solvents such as ionic liquid and/or methods such as supercritical fluid (CO2) extraction. In this chapter conventional and novel extraction methods and the most common cell disruption techniques are discussed. Among the novel methods, the chapter focuses on ionic liquid, supercritical fluid extraction, and pressure liquid extraction.
