Fractions lipidiques obtenues à partir des co-produits de la filière halieutique

Abstract

The purpose of this paper was to take stock of the economic situation on the co-products coming from the fish factories. Such co-products contain large amounts of long-chain polyunsaturated fatty acids (LC-PUFA), mainly docosahexaenoic acid (C22 :6 n-3) and eicosapentaenoic acid (C20 :5 n-3). Several extraction processes (thermal treatments, solvent extraction, enzymatic methods) are taking place, considering the importance of these components in human health. Some amphiphilic molecules, which contain high amounts of LC-PUFA may find outlets in nutraceutics, cosmetics and in the food industry, provided their safety and quality are guaranteed.
