Les agro-solvants pour l'extraction des huiles végétales issues de graines oléagineuses

Abstract

Oils represent an important part in human diet and contain essential nutriments. Consumers are more and more swayed by the argument of product origin. As for industries, they understood it's not possible anymore to produce without thinking about the environment. This article deals with the use of agro-solvents to substitute hexane which is the most widely used solvent in oilseed extraction. Indeed, hexane presents numerous drawbacks like high flammability, dangerousness for health and environment and a non-renewable origin. Its use in the field of extraction is discussed since the 80s with a renewed intensity since the 00s. An overview of alternative solvents was presented. © 2013 F.
