Valorization of a biomass: phytochemicals in oilseed by-products

A huge amount of residue is released every year in agricultural and food industries. If this waste is valorised properly, it would be very beneficial from both economic and environmental aspects. Recently, seeds of oil crops have been getting great interest due to their waste rich in a great variety of lipophilic and hydrophilic phytochemicals. On the other hand, oilseed processing by-products comprise approximately 35 millions of tons seed for oil in European Union. Therefore, this remarkable amount of residue should be considered as a resource from waste to health. The purpose of the present research is to introduce the types of oilseed by-product and their high added value phytochemicals by summarizing the recent studies on the valorization of different wastes of several oilseed crops. This research also supplies an overview of the oilseed sources with their botanical names, production regions and target phytochemical ingredients. Moreover, further remarks with some certain concerns are discussed
