Abstract
A method for extracting an unsaponifiable fraction from a renewable raw material selected among oilfruits, oleaginous seeds, oleoproteaginous seeds, seed husks, oil-yielding almonds, sprouts, stones and cuticles of fruits, high-fat raw materials from animals, algae, fungus or yeast, includes the following steps: a) dehydrating and packaging the renewable raw material, not resulting in any extraction of the fat; b) reactive crushing of the fatty packaged raw material in the presence of a light alcohol and a catalyst; c) evaporating the light alcohol; d) concentrating the liquid phase such as to obtain a concentrate including the unsaponifiable fraction diluted in fatty acid alkyl esters; e) saponifying the unsaponifiable concentrate; f) extracting the unsaponifiable fraction from the saponified mixture. The use of an unsaponifiable fraction or co-products obtained by implementing the method for preparing a composition such as a cosmetic, drug, food, or food additive or supplement is also described.
